From 87942d51215f6aa6dcc83da4ed3171ab24d34426 Mon Sep 17 00:00:00 2001 From: Mikhail Burshteyn Date: Tue, 21 May 2019 00:56:41 +0300 Subject: [PATCH 0001/1817] Add check in @addpattern whether the function is pattern-matching Compiler now emits a statement which sets `_coconut_is_pattern_matching` flag on pattern-matching functions. This flag is checked in `@addpattern`, which emits a `UserWarning` if it encounters a function for which the flag is missing.

Lazy lists use the same machinery as iterator chaining to make themselves lazy, and thus the lazy list `(| x, y |)` is equivalent to the iterator chaining expression `(x,) :: (y,)`, although the lazy list won't construct the intermediate tuples. diff --git a/coconut/compiler/util.py b/coconut/compiler/util.py index 257812024..c6a8377bf 100644 --- a/coconut/compiler/util.py +++ b/coconut/compiler/util.py @@ -423,12 +423,12 @@ def tokenlist(item, sep, suppress=True): def itemlist(item, sep, suppress_trailing=True): - """Create a list of items seperated by seps.""" + """Create a list of items separated by seps.""" return condense(item + ZeroOrMore(addspace(sep + item)) + Optional(sep.suppress() if suppress_trailing else sep)) def exprlist(expr, op): - """Create a list of exprs seperated by ops.""" + """Create a list of exprs separated by ops.""" return addspace(expr + ZeroOrMore(op + expr)) From 5b97a39db7d7939a5ad9dc27302c08d1509ae973 Mon Sep 17 00:00:00 2001 From: Evan Hubinger Date: Sun, 13 Sep 2020 16:31:12 -0700 Subject: [PATCH 0130/1817] Only wrap annotations when necessary Resolves #553. --- coconut/compiler/compiler.py | 13 ++++++++++--- coconut/root.py | 2 +- 2 files changed, 11 insertions(+), 4 deletions(-) diff --git a/coconut/compiler/compiler.py b/coconut/compiler/compiler.py index 375d0c576..56ce27c7a 100644 --- a/coconut/compiler/compiler.py +++ b/coconut/compiler/compiler.py @@ -421,8 +421,6 @@ def setup(self, target=None, strict=False, minify=False, line_numbers=False, kee "unsupported target Python version " + ascii(target), extra="supported targets are " + ', '.join(ascii(t) for t in specific_targets) + ", or leave blank for universal", ) - if no_wrap and not target.startswith("3"): - logger.warn("--no-wrap argument has no effect on target " + ascii(target if target else "universal"), extra="only Python 3 targets support non-comment type annotations") logger.log_vars("Compiler args:", locals()) self.target = target self.strict = strict @@ -431,6 +429,15 @@ def setup(self, target=None, strict=False, minify=False, line_numbers=False, kee self.keep_lines = keep_lines self.no_tco = no_tco self.no_wrap = no_wrap + if self.no_wrap: + if not self.target.startswith("3"): + errmsg = "only Python 3 targets support non-comment type annotations" + elif self.target_info >= (3, 7): + errmsg = "annotations are never wrapped on targets with PEP 563 support" + else: + errmsg = None + if errmsg is not None: + logger.warn("--no-wrap argument has no effect on target " + ascii(target if target else "universal"), extra=errmsg) def __reduce__(self): """Return pickling information.""" @@ -2177,7 +2184,7 @@ def unsafe_typedef_handle(self, tokens): def wrap_typedef(self, typedef): """Wrap a type definition in a string to defer it unless --no-wrap.""" - if self.no_wrap: + if self.no_wrap or self.target_info >= (3, 7): return typedef else: return self.wrap_str_of(self.reformat(typedef)) diff --git a/coconut/root.py b/coconut/root.py index 23833c4ac..b3a7f9ce3 100644 --- a/coconut/root.py +++ b/coconut/root.py @@ -26,7 +26,7 @@ VERSION = "1.4.3" VERSION_NAME = "Ernest Scribbler" # False for release, int >= 1 for develop -DEVELOP = 46 +DEVELOP = 47 # ----------------------------------------------------------------------------------------------------------------------- # CONSTANTS: From 811291f12da8913469ce5eb8a4af35839d4844c1 Mon Sep 17 00:00:00 2001 From: Evan Hubinger Date: Sun, 13 Sep 2020 17:35:17 -0700 Subject: [PATCH 0131/1817] Add support for breakpoint built-in Resolves #552. --- DOCS.md | 26 ++++++++-- coconut/__init__.py | 6 +-- coconut/compiler/header.py | 4 +- coconut/constants.py | 5 +- coconut/root.py | 59 ++++++++++++++++++----- coconut/stubs/__coconut__.pyi | 4 ++ tests/src/cocotest/agnostic/main.coco | 14 +++++- tests/src/cocotest/agnostic/specific.coco | 6 +++ 8 files changed, 104 insertions(+), 20 deletions(-) diff --git a/DOCS.md b/DOCS.md index b9dcf3418..ea7c71e5d 100644 --- a/DOCS.md +++ b/DOCS.md @@ -204,7 +204,27 @@ By default, if the `source` argument to the command-line utility is a file, it w While Coconut syntax is based off of Python 3, Coconut code compiled in universal mode (the default `--target`), and the Coconut compiler, should run on any Python version `>= 2.6` on the `2.x` branch or `>= 3.2` on the `3.x` branch on either [CPython](https://www.python.org/) or [PyPy](http://pypy.org/). -To make Coconut built-ins universal across Python versions, **Coconut automatically overwrites Python 2 built-ins with their Python 3 counterparts**.

Immutable data can be very useful because it guarantees that once you have some data it won't change, but in Python creating custom immutable data types is difficult. Coconut makes it very easy by providing `data` blocks. -##### Python Docs - -Returns a new tuple subclass. The new subclass is used to create tuple-like objects that have fields accessible by attribute lookup as well as being indexable and iterable. Instances of the subclass also have a helpful docstring (with type names and field names) and a helpful `__repr__()` method which lists the tuple contents in a `name=value` format. - -Any valid Python identifier may be used for a field name except for names starting with an underscore.

As a result of this, many of Coconut's open issues are [labeled](https://github.com/evhub/coconut/labels) with bounties denoting the compensation available for resolving them. If you successfully resolve one of these issues (defined as getting a pull request resolving the issue merged), you become eligible to collect that issue's bounty. To do so, simply [file an expense report](https://opencollective.com/coconut/expenses/new#) for the correct amount with a link to the issue you resolved. - -If an issue you really want fixed or an issue you're really excited to work on doesn't currently have a bounty on it, please leave a comment on the issue!

Additionally, Coconut adds special syntax for making type annotations easier and simpler to write. When inside of a type annotation, Coconut treats certain syntax constructs differently, compiling them to type annotations instead of what they would normally represent.

Immutable data can be very useful because it guarantees that once you have some data it won't change, but in Python creating custom immutable data types is difficult. Coconut makes it very easy by providing `data` blocks. -##### Python Docs - -Returns a new tuple subclass. The new subclass is used to create tuple-like objects that have fields accessible by attribute lookup as well as being indexable and iterable. Instances of the subclass also have a helpful docstring (with type names and field names) and a helpful `__repr__()` method which lists the tuple contents in a `name=value` format. - -Any valid Python identifier may be used for a field name except for names starting with an underscore.

As a result of this, many of Coconut's open issues are [labeled](https://github.com/evhub/coconut/labels) with bounties denoting the compensation available for resolving them. If you successfully resolve one of these issues (defined as getting a pull request resolving the issue merged), you become eligible to collect that issue's bounty. To do so, simply [file an expense report](https://opencollective.com/coconut/expenses/new#) for the correct amount with a link to the issue you resolved. - -If an issue you really want fixed or an issue you're really excited to work on doesn't currently have a bounty on it, please leave a comment on the issue!

Additionally, Coconut adds special syntax for making type annotations easier and simpler to write. When inside of a type annotation, Coconut treats certain syntax constructs differently, compiling them to type annotations instead of what they would normally represent.

Implicit function application has a lower precedence than attribute access, slices, normal function calls, etc. but a higher precedence than `await`. Supported arguments to implicit function application are highly restricted, and must be either variables/attributes or **non-string** constants (e.g. `f x 1` will work but `f x [1]`, `f x (1+2)`, and `f "abc"` will not). Strings are disallowed due to conflicting with [Python's implicit string concatenation](https://stackoverflow.com/questions/18842779/string-concatenation-without-operator). Implicit function application is only intended for simple use cases—for more complex cases, use either standard function application or [pipes](#pipeline). diff --git a/coconut/compiler/compiler.py b/coconut/compiler/compiler.py index 053e5130e..d40779cd8 100644 --- a/coconut/compiler/compiler.py +++ b/coconut/compiler/compiler.py @@ -480,7 +480,7 @@ def bind(self): self.datadef <<= attach(self.datadef_ref, self.datadef_handle) self.match_datadef <<= attach(self.match_datadef_ref, self.match_datadef_handle) self.with_stmt <<= attach(self.with_stmt_ref, self.with_stmt_handle) -

In this case, `vector()` would only match a _zero-length_ vector, not just any vector. + The other new construct used here is the `|*>`, or star-pipe, operator, which functions exactly like the normal pipe, except that instead of calling the function with one argument, it calls it with as many arguments as there are elements in the sequence passed into it. The difference between `|>` and `|*>` is exactly analogous to the difference between `f(args)` and `f(*args)`. ### n-Vector Methods @@ -607,7 +628,7 @@ data vector(*pts): """Immutable n-vector.""" def __new__(cls, *pts): """Create a new vector from the given pts.""" - match [v is vector] in pts: + match [v `isinstance` vector] in pts: return v # vector(v) where v is a vector should return v else: return pts |*> makedata$(cls) # accesses base constructor @@ -806,7 +827,7 @@ data vector(*pts): """Immutable n-vector.""" def __new__(cls, *pts): """Create a new vector from the given pts.""" - match [v is vector] in pts: + match [v `isinstance` vector] in pts: return v # vector(v) where v is a vector should return v else: return pts |*> makedata$(cls) # accesses base constructor @@ -974,7 +995,7 @@ _Hint: Look back at how we checked whether the argument to `factorial` was an in Here's my solution—take a look: ```coconut - def angle(self, other is vector) = math.acos(self.unit() * other.unit()) + def angle(self, other `isinstance` vector) = math.acos(self.unit() * other.unit()) ``` And now it's time to put it all together.

By default, all multidimensional array syntax will simply operate on Python lists of lists. However, if [`numpy`](http://www.numpy.org/) objects are used, the appropriate `numpy` calls will be made instead. + +As a simple example, 2D matrices can be constructed by separating the rows with `;;` inside of a list literal +```coconut_pycon +>>> [1, 2 ;; + 3, 4] + +[[1, 2], [3, 4]] +>>> import numpy as np +>>> np.array([1, 2 ;; 3, 4]) +array([[1, 2], + [3, 4]]) +``` +and as can be seen, `np.array` (or equivalent) can be used to turn the resulting list of lists into an actual array. This syntax works because `;;` inside of a list functions as a concatenation/stack along the `-2` axis, with the inner arrays being broadcast to `(1, 2)` arrays before concatenation. Note that this concatenation is done entirely in Python lists of lists here, since the `np.array` call comes only at the end. + +In general, the number of semicolons indicates the dimension from the end on which to concatenate. Thus, `;` indicates conatenation along the `-1` axis, `;;` along the `-2` axis, and so on. Before concatenation, arrays are always broadcast to a shape which is large enough to allow the concatenation. + +Thus, if `a` is a `numpy` array, `[a; a]` is equivalent to `np.concatenate((a, a), axis=-1)`, while `[a ;; a]` would be equivalent to a version of `np.concatenate((a, a), axis=-2)` that also ensures that `a` is at least two dimensional. For normal lists of lists, the behavior is the same, but is implemented without any `numpy` calls. + +If multiple different concatenation operators are used, the operators with the least number of semicolons will bind most tightly. Thus, you can write a 3D array literal as: +```coconut_pycon +>>> [1, 2 ;; + 3, 4 + ;;; + 5, 6 ;; + 7, 8] + +[[[1, 2], [3, 4]], [[5, 6], [7, 8]]] +``` + +##### Comparison to Julia + +Coconut's multidimensional array syntax is based on that of [Julia](https://docs.julialang.org/en/v1/manual/arrays/#man-array-literals). The primary difference between Coconut's syntax and Julia's syntax is that multidimensional arrays are row-first in Coconut (following `numpy`), but column-first in Julia. Thus, `;` is vertical concatenation in Julia but **horizontal concatenation** in Coconut and `;;` is horizontal concatenation in Julia but **vertical concatenation** in Coconut. + +##### Examples + +**Coconut:** +```coconut_pycon +>>> [[1;;2] ; [3;;4]] +[[1, 3], [2, 4]] +``` +_Array literals can be written in column-first order if the columns are first created via vertical concatenation (`;;`) and then joined via horizontal concatenation (`;`)._ + +```coconut_pycon +>>> [range(3) |> list ;; x+1 for x in range(3)] +[[0, 1, 2], [1, 2, 3]] +``` +_Arbitrary expressions, including comprehensions, are allowed in multidimensional array literals._ + +```coconut_pycon +>>> import numpy as np +>>> a = np.array([1, 2 ;; 3, 4]) +>>> [a ; a] +array([[1, 2, 1, 2], + [3, 4, 3, 4]]) +>>> [a ;; a] +array([[1, 2], + [3, 4], + [1, 2], + [3, 4]]) +>>> [a ;;; a] +array([[[1, 2], + [3, 4]], + + [[1, 2], + [3, 4]]]) +``` +_General showcase of how the different concatenation operators work using `numpy` arrays._ + +**Python:** _The equivalent Python array literals can be seen in the printed representations in each example._ + +### Lazy Lists + +Coconut supports the creation of lazy lists, where the contents in the list will be treated as an iterator and not evaluated until they are needed. Unlike normal iterators, however, lazy lists can be iterated over multiple times and still return the same result. Lazy lists can be created in Coconut simply by surrounding a comma-separated list of items with `(|` and `|)` (so-called "banana brackets") instead of `[` and `]` for a list or `(` and `)` for a tuple. + +Lazy lists use [reiterable](#reiterable) under the hood to enable them to be iterated over multiple times. + +##### Rationale + +Lazy lists, where sequences are only evaluated when their contents are requested, are a mainstay of functional programming, allowing for dynamic evaluation of the list's contents. + +##### Example + +**Coconut:** +```coconut +(| print("hello,"), print("world!") |) |> consume +``` + +**Python:** +_Can't be done without a complicated iterator comprehension in place of the lazy list. See the compiled code for the Python syntax._ + +### Implicit Function Application + +Coconut supports implicit function application of the form `f x y`, which is compiled to `f(x, y)` (note: **not** `f(x)(y)` as is common in many languages with automatic currying). Implicit function application has a lower precedence than attribute access, slices, normal function calls, etc. but a higher precedence than `await`. + +Supported arguments to implicit function application are highly restricted, and must be either variables/attributes or **non-string** constants (e.g. `f x 1` will work but `f x [1]`, `f x (1+2)`, and `f "abc"` will not). Strings are disallowed due to conflicting with [Python's implicit string concatenation](https://stackoverflow.com/questions/18842779/string-concatenation-without-operator). Implicit function application is only intended for simple use cases—for more complex cases, use either standard function application or [pipes](#pipeline). + +##### Examples + +**Coconut:** +```coconut +def f(x, y) = (x, y) +print(f 5 10) +``` + +```coconut +def p1(x) = x + 1 +print <| p1 5 +``` + +**Python:** +```coconut_python +def f(x, y): return (x, y) +print(f(100, 5+6)) +``` + +```coconut_python +def p1(x): return x + 1 +print(p1(5)) +``` + ### Anonymous Namedtuples Coconut supports anonymous [`namedtuple`](https://docs.python.org/3/library/collections.html#collections.namedtuple) literals, such that `(a=1, b=2)` can be used just as `(1, 2)`, but with added names. @@ -2084,6 +2126,38 @@ depth: 1 --- ``` +### Expanded Indexing for Iterables + +Beyond indexing standard Python sequences, Coconut supports indexing into a number of built-in iterables, including `range` and `map`, which do not support random access in all Python versions but do in Coconut.

In this case, `fmap` is simply `map` plus a call to the object's constructor. ### n-Vector Constructor @@ -567,7 +567,7 @@ vector(1, 2, 3) |> print # vector(*pts=(1, 2, 3)) vector(4, 5) |> vector |> print # vector(*pts=(4, 5)) ``` -Copy, paste!

For example, `` x `isinstance` int `` will check that whatever is in that position `isinstance$(?, int)` and bind it to `x`. Can be used with [`match_if`](#match_if) to check if an arbitrary predicate holds. -- Classes or Data Types (`()`): will match as a data type if given [a Coconut `data` type](#data) (or a tuple of Coconut data types) and a class otherwise. -- Data Types (`data ()`): will check that whatever is in that position is of data type `` and will match the attributes to ``.

In this case, the constructor checks whether nothing but another `vector` was passed, in which case it returns that, otherwise it returns the result of passing the arguments to the underlying constructor, the form of which is `vector(*pts)`, since that is how we declared the data type. We use sequence pattern-matching to determine whether we were passed a single vector, which is just a list or tuple of patterns to match against the contents of the sequence.

To achieve this, Coconut provides the [built-in `makedata` function](./DOCS.md#makedata), which takes a data type and calls its underlying `data` constructor with the rest of the arguments. In this case, the constructor checks whether nothing but another `vector` was passed, in which case it returns that, otherwise it returns the result of passing the arguments to the underlying constructor, the form of which is `vector(*pts)`, since that is how we declared the data type. We use sequence pattern-matching to determine whether we were passed a single vector, which is just a list or tuple of patterns to match against the contents of the sequence.

Passing `--target` helps Coconut optimize the compiled code for the Python version you want, and, though [Tail Call Optimization](./DOCS.md#tail-call-optimization) is useful, it will usually significantly slow down functions that use it, so disabling it will often provide a major performance boost. +### When I try to use Coconut on the command line, I get weird unprintable characters and numbers; how do I get rid of them? + +You're probably seeing color codes while using a terminal that doesn't support them (e.g. Windows `cmd`). Try setting the `COCONUT_USE_COLOR` environment variable to `FALSE` to get rid of them. + ### I want to contribute to Coconut, how do I get started? That's great! Coconut is completely open-source, and new contributors are always welcome. Check out Coconut's [contributing guidelines](./CONTRIBUTING.md) for more information.

Second, if you're using runtime type checking, you'll need to pass the `--no-wrap` argument, which will tell Coconut not to wrap type annotations in strings. When using type annotations for static type checking, wrapping them in strings is preferred, but when using them for runtime type checking, you'll want to disable it. + +### When I try to use Coconut on the command line, I get weird unprintable characters and numbers; how do I get rid of them? + +You're probably seeing color codes while using a terminal that doesn't support them (e.g. Windows `cmd`). Try setting the `COCONUT_USE_COLOR` environment variable to `FALSE` to get rid of them. ### How will I be able to debug my Python if I'm not the one writing it? Ease of debugging has long been a problem for all compiled languages, including languages like `C` and `C++` that these days we think of as very low-level languages. The solution to this problem has always been the same: line number maps. If you know what line in the compiled code corresponds to what line in the source code, you can easily debug just from the source code, without ever needing to deal with the compiled code at all. In Coconut, this can easily be accomplished by passing the `--line-numbers` or `-l` flag, which will add a comment to every line in the compiled code with the number of the corresponding line in the source code. Alternatively, `--keep-lines` or `-k` will put in the verbatim source line instead of or in addition to the source line number. Then, if Python raises an error, you'll be able to see from the snippet of the compiled code that it shows you a comment telling you what line in your source code you need to look at to debug the error. +### If I'm already perfectly happy with Python, why should I learn Coconut? + +You're exactly the person Coconut was built for!

Definitely! While Coconut is great for functional programming, it also has a bunch of other awesome features as well, including the ability to compile Python 3 code into universal Python code that will run the same on _any version_. And that's not even mentioning all of the features like pattern-matching and destructuring assignment with utility extending far beyond just functional programming.

The LRU feature performs best when _maxsize_ is a power-of-two. +Distinct argument patterns may be considered to be distinct calls with separate cache entries.

For example, `f(3)` and `f(3.0)` will be treated as distinct calls with distinct results. +If _typed_ is set to true, function arguments of different types will be cached separately. If typed is false, the implementation will usually regard them as equivalent calls and only cache a single result. (Some types such as str and int may be cached separately even when typed is false.) -To help measure the effectiveness of the cache and tune the _maxsize_ parameter, the wrapped function is instrumented with a `cache_info()` function that returns a named tuple showing _hits_, _misses_, _maxsize_ and _currsize_. In a multi-threaded environment, the hits and misses are approximate. +Note, type specificity applies only to the function’s immediate arguments rather than their contents. The scalar arguments, `Decimal(42)` and `Fraction(42)` are be treated as distinct calls with distinct results. In contrast, the tuple arguments `('answer', Decimal(42))` and `('answer', Fraction(42))` are treated as equivalent. The decorator also provides a `cache_clear()` function for clearing or invalidating the cache. The original underlying function is accessible through the `__wrapped__` attribute. This is useful for introspection, for bypassing the cache, or for rewrapping the function with a different cache. -An LRU (least recently used) cache works best when the most recent calls are the best predictors of upcoming calls (for example, the most popular articles on a news server tend to change each day).

When Coconut compiles a `.coco` (or `.coc`/`.coconut`) file, it will compile to another file with the same name, except with `.py` instead of `.coco`, which will hold the compiled code. If an extension other than `.py` is desired for the compiled files, such as `.pyde` for [Python Processing](http://py.processing.org/), then that extension can be put before `.coco` in the source file name, and it will be used instead of `.py` for the compiled files. For example, `name.coco` will compile to `name.py`, whereas `name.pyde.coco` will compile to `name.pyde`. -### Compilation Modes +#### Compilation Modes Files compiled by the `coconut` command-line utility will vary based on compilation parameters. If an entire directory of files is compiled (which the compiler will search recursively for any folders containing `.coco`, `.coc`, or `.coconut` files), a `__coconut__.py` file will be created to house necessary functions (package mode), whereas if only a single file is compiled, that information will be stored within a header inside the file (standalone mode). Standalone mode is better for single files because it gets rid of the overhead involved in importing `__coconut__.py`, but package mode is better for large packages because it gets rid of the need to run the same Coconut header code again in every file, since it can just be imported from `__coconut__.py`. By default, if the `source` argument to the command-line utility is a file, it will perform standalone compilation on it, whereas if it is a directory, it will recursively search for all `.coco` (or `.coc` / `.coconut`) files and perform package compilation on them. Thus, in most cases, the mode chosen by Coconut automatically will be the right one. But if it is very important that no additional files like `__coconut__.py` be created, for example, then the command-line utility can also be forced to use a specific mode with the `--package` (`-p`) and `--standalone` (`-a`) flags. -### Compatible Python Versions +#### Compatible Python Versions While Coconut syntax is based off of the latest Python 3, Coconut code compiled in universal mode (the default `--target`)—and the Coconut compiler itself—should run on any Python version `>= 2.6` on the `2.x` branch or `>= 3.2` on the `3.x` branch (and on either [CPython](https://www.python.org/) or [PyPy](http://pypy.org/)). @@ -275,7 +275,7 @@ Finally, while Coconut will try to compile Python-3-specific syntax to its unive - `a[x, *y]` variadic generic syntax (use [type parameter syntax](#type-parameter-syntax) for universal code) (requires `--target 3.11`), and - `except*` multi-except statements (requires `--target 3.11`). -### Allowable Targets +#### Allowable Targets If the version of Python that the compiled code will be running on is known ahead of time, a target should be specified with `--target`.

Specifically, instead of writing ```coconut -pairs = range(1, 11) |> groupsof$(2) +seq = get_elem() :: seq ``` +which will crash due to the aforementioned Python issue, write +```coconut +@recursive_iterator +def seq() = get_elem() :: seq() +``` +which will work just fine. -**Python:** -```coconut_python -pairs = [] -group = [] -for item in range(1, 11): - group.append(item) - if len(group) == 2: - pairs.append(tuple(group)) - group = [] -if group: - pairs.append(tuple(group)) +One pitfall to keep in mind working with `recursive_iterator` is that it shouldn't be used in contexts where the function can potentially be called multiple times with the same iterator object as an input, but with that object not actually corresponding to the same items (e.g. because the first time the object hasn't been iterated over yet and the second time it has been). + +##### Example + +**Coconut:** +```coconut +@recursive_iterator +def fib() = (1, 1) :: map((+), fib(), fib()$[1:]) ``` -### `reiterable` +**Python:** +_Can't be done without a long decorator definition. The full definition of the decorator in Python can be found in the Coconut header._ + +### Built-In Types -**reiterable**(_iterable_) +#### `multiset` -`reiterable` wraps the given iterable to ensure that every time the `reiterable` is iterated over, it produces the same results. Note that the result need not be a `reiterable` object if the given iterable is already reiterable. `reiterable` uses [`tee`](#tee) under the hood and `tee` can be used in its place, though `reiterable` is generally recommended over `tee`. +**multiset**(_iterable_=`None`, /, **kwds) + +Coconut provides `multiset` as a built-in subclass of [`collections.Counter`](https://docs.python.org/3/library/collections.html#collections.Counter) that additionally implements the full [Set and MutableSet interfaces](https://docs.python.org/3/library/collections.abc.html). + +For easily constructing multisets, Coconut also provides [multiset literals](#set-literals). + +The new methods provided by `multiset` on top of `collections.Counter` are: +- multiset.**add**(_item_): Add an element to a multiset. +- multiset.**discard**(_item_): Remove an element from a multiset if it is a member. +- multiset.**remove**(_item_): Remove an element from a multiset; it must be a member. +- multiset.**isdisjoint**(_other_): Return True if two multisets have a null intersection. +- multiset.**__xor__**(_other_): Return the symmetric difference of two multisets as a new multiset. Specifically: `a ^ b = (a - b) | (b - a)` +- multiset.**count**(_item_): Return the number of times an element occurs in a multiset. Equivalent to `multiset[item]`, but additionally verifies the count is non-negative. + +Coconut also ensures that `multiset` supports [rich comparisons and `Counter.total()`](https://docs.python.org/3/library/collections.html#collections.Counter) on all Python versions. ##### Example **Coconut:** ```coconut -def list_type(xs): - match reiterable(xs): - case [fst, snd] :: tail: - return "at least 2" - case [fst] :: tail: - return "at least 1" - case (| |): - return "empty" +my_multiset = m{1, 1, 2} +my_multiset.add(3) +my_multiset.remove(2) +print(my_multiset) ``` **Python:** -_Can't be done without a long series of checks for each `match` statement.

Note that all [Sequences/Mappings/Sets](https://docs.python.org/3/library/collections.abc.html) are always assumed to be reiterable even without calling `__copy__`. +`Expected` is primarily used as the return type for [`safe_call`](#safe_call). Generally, the best way to use `Expected` is with [`fmap`](#fmap), which will apply a function to the result if it exists, or otherwise retain the error. + +##### Example + +**Coconut:** +```coconut +def try_divide(x, y): + try: + return Expected(x / y) + except Exception as err: + return Expected(error=err) + +try_divide(1, 2) |> fmap$(.+1) |> print +try_divide(1, 0) |> fmap$(.+1) |> print +``` + +**Python:** +_Can't be done without a complex `Expected` definition. See the compiled code for the Python syntax._ + +#### `MatchError` + +A `MatchError` is raised when a [destructuring assignment](#destructuring-assignment) or [pattern-matching function](#pattern-matching-functions) fails, and thus `MatchError` is provided as a built-in for catching those errors. `MatchError` objects support three attributes: `pattern`, which is a string describing the failed pattern; `value`, which is the object that failed to match that pattern; and `message` which is the full error message. To avoid unnecessary `repr` calls, `MatchError` only computes the `message` once it is actually requested. + +Additionally, if you are using [view patterns](#match), you might need to raise your own `MatchError` (though you can also just use a destructuring assignment or pattern-matching function definition to do so). To raise your own `MatchError`, just `raise MatchError(pattern, value)` (both arguments are optional). + +### Generic Built-In Functions + +#### `makedata` + +**makedata**(_data\_type_, *_args_) + +Coconut provides the `makedata` function to construct a container given the desired type and contents.

The behavior of `fmap` for a given object can be overridden by defining an `__fmap__(self, func)` magic method that will be called whenever `fmap` is invoked on that object. + +For `dict`, or any other `collections.abc.Mapping`, `fmap` will map over the mapping's `.items()` instead of the default iteration through its `.keys()`, with the new mapping reconstructed from the mapped over items. Additionally, for backwards compatibility with old versions of Coconut, `fmap$(starmap_over_mappings=True)` will `starmap` over the `.items()` instead of `map` over them. + +For [`numpy`](#numpy-integration) objects, `fmap` will use [`np.vectorize`](https://docs.scipy.org/doc/numpy/reference/generated/numpy.vectorize.html) to produce the result. + +For asynchronous iterables, `fmap` will map asynchronously, making `fmap` equivalent in that case to: +```coconut_python +async def fmap_over_async_iters(func, async_iter): + async for item in async_iter: + yield func(item) +``` + +For `None`, `fmap` will always return `None`, ignoring the function passed to it. + +##### Example + +**Coconut:** +```coconut +[1, 2, 3] |> fmap$(x -> x+1) == [2, 3, 4] + +class Maybe +data Nothing() from Maybe +data Just(n) from Maybe + +Just(3) |> fmap$(x -> x*2) == Just(6) +Nothing() |> fmap$(x -> x*2) == Nothing() +``` + +**Python:** +_Can't be done without a series of method definitions for each data type.

Thus, `ident` is effectively equivalent to: +```coconut +def ident(x, *, side_effect=None): + if side_effect is not None: + side_effect(x) + return x +``` + +`ident` is primarily useful when writing in a point-free style (e.g. in combination with [`lift`](#lift)) or for debugging [pipes](#pipes) where `ident$(side_effect=print)` can let you see what is being piped. + +### Built-Ins for Working with Iterators + +#### Enhanced Built-Ins + +Coconut's `map`, `zip`, `filter`, `reversed`, and `enumerate` objects are enhanced versions of their Python equivalents that support: + +- `reversed` +- `repr` +- Optimized normal (and iterator) indexing/slicing (`map`, `zip`, `reversed`, and `enumerate` but not `filter`) +- `len` (all but `filter`) (though `bool` will still always yield `True`) +- The ability to be iterated over multiple times if the underlying iterators can be iterated over multiple times +- [PEP 618](https://www.python.org/dev/peps/pep-0618) `zip(..., strict=True)` support on all Python versions +- Added attributes which subclasses can make use of to get at the original arguments to the object: + * `map`: `func`, `iters` + * `zip`: `iters` + * `filter`: `func`, `iter` + * `reversed`: `iter` + * `enumerate`: `iter`, `start` + +##### Indexing into other built-ins + +Though Coconut provides random access indexing/slicing to `range`, `map`, `zip`, `reversed`, and `enumerate`, Coconut cannot index into built-ins like `filter`, `takewhile`, or `dropwhile` directly, as there is no efficient way to do so. + +```coconut +range(10) |> filter$(i->i>3) |> .[0] # doesn't work +``` + +In order to make this work, you can explicitly use iterator slicing, which is less efficient in the general case: + +```coconut +range(10) |> filter$(i->i>3) |> .$[0] # works +``` + +For more information on Coconut's iterator slicing, see [here](#iterator-slicing). + +##### Examples + +**Coconut:** +```coconut +map((+), range(5), range(6)) |> len |> print +range(10) |> filter$((x) -> x < 5) |> reversed |> tuple |> print +``` + +**Python:** +_Can't be done without defining a custom `map` type.

The left argument, _x_, is the accumulated value and the right argument, _y_, is the update value from the _sequence_. If the optional _initial_ is present, it is placed before the items of the sequence in the calculation, and serves as a default when the sequence is empty.

If any exceptions are raised inside of `parallel_map`, a traceback will be printed as soon as they are encountered. Because `parallel_map` uses multiple processes for its execution, it is necessary that all of its arguments be pickleable. Only objects defined at the module level, and not lambdas, objects defined inside of a function, or objects defined inside of the interpreter, are pickleable. Furthermore, on Windows, it is necessary that all calls to `parallel_map` occur inside of an `if __name__ == "__main__"` guard. +`parallel_map` supports a `chunksize` argument, which determines how many items are passed to each process at a time. Larger values of _chunksize_ are recommended when dealing with very long iterables. Additionally, in the multi-iterable case, _strict_ can be set to `True` to ensure that all iterables are the same length. + If multiple sequential calls to `parallel_map` need to be made, it is highly recommended that they be done inside of a `with parallel_map.multiple_sequential_calls():` block, which will cause the different calls to use the same process pool and result in `parallel_map` immediately returning a list rather than a `parallel_map` object. If multiple sequential calls are necessary and the laziness of parallel_map is required, then the `parallel_map` objects should be constructed before the `multiple_sequential_calls` block and then only iterated over once inside the block. `parallel_map.multiple_sequential_calls` also supports a `max_workers` argument to set the number of processes. @@ -3681,7 +3684,7 @@ with Pool() as pool: #### `concurrent_map` -**concurrent\_map**(_function_, *_iterables_, *, _chunksize_=`1`) +**concurrent\_map**(_function_, *_iterables_, *, _chunksize_=`1`, _strict_=`False`) Coconut provides a concurrent version of [`parallel_map`](#parallel_map) under the name `concurrent_map`. `concurrent_map` behaves identically to `parallel_map` (including support for `concurrent_map.multiple_sequential_calls`) except that it uses multithreading instead of multiprocessing, and is therefore primarily useful only for IO-bound tasks due to CPython's Global Interpreter Lock. diff --git a/Makefile b/Makefile index bf772266c..0d39111b3 100644 --- a/Makefile +++ b/Makefile @@ -198,6 +198,10 @@ test-watch: clean test-mini: coconut ./coconut/tests/src/cocotest/agnostic ./coconut/tests/dest/cocotest --force --jobs 0 +.PHONY: debug-test-crash +debug-test-crash: + python -X dev ./coconut/tests/dest/runner.py + .PHONY: diff diff: git diff origin/develop @@ -214,12 +218,12 @@ docs: clean .PHONY: clean clean: rm -rf ./docs ./dist ./build ./coconut/tests/dest ./bbopt ./pyprover ./pyston ./coconut-prelude index.rst ./.mypy_cache -

Second, if you're using runtime type checking, you'll need to pass the `--no-wrap` argument, which will tell Coconut not to wrap type annotations in strings. When using type annotations for static type checking, wrapping them in strings is preferred, but when using them for runtime type checking, you'll want to disable it. + +### When I try to use Coconut on the command line, I get weird unprintable characters and numbers; how do I get rid of them? + +You're probably seeing color codes while using a terminal that doesn't support them (e.g. Windows `cmd`). Try setting the `COCONUT_USE_COLOR` environment variable to `FALSE` to get rid of them. ### How will I be able to debug my Python if I'm not the one writing it? Ease of debugging has long been a problem for all compiled languages, including languages like `C` and `C++` that these days we think of as very low-level languages. The solution to this problem has always been the same: line number maps. If you know what line in the compiled code corresponds to what line in the source code, you can easily debug just from the source code, without ever needing to deal with the compiled code at all. In Coconut, this can easily be accomplished by passing the `--line-numbers` or `-l` flag, which will add a comment to every line in the compiled code with the number of the corresponding line in the source code. Alternatively, `--keep-lines` or `-k` will put in the verbatim source line instead of or in addition to the source line number. Then, if Python raises an error, you'll be able to see from the snippet of the compiled code that it shows you a comment telling you what line in your source code you need to look at to debug the error. +### If I'm already perfectly happy with Python, why should I learn Coconut? + +You're exactly the person Coconut was built for!

Definitely! While Coconut is great for functional programming, it also has a bunch of other awesome features as well, including the ability to compile Python 3 code into universal Python code that will run the same on _any version_. And that's not even mentioning all of the features like pattern-matching and destructuring assignment with utility extending far beyond just functional programming.

If typed is false, the implementation will usually regard them as equivalent calls and only cache a single result. (Some types such as str and int may be cached separately even when typed is false.) -To help measure the effectiveness of the cache and tune the _maxsize_ parameter, the wrapped function is instrumented with a `cache_info()` function that returns a named tuple showing _hits_, _misses_, _maxsize_ and _currsize_.

The scalar arguments, `Decimal(42)` and `Fraction(42)` are be treated as distinct calls with distinct results. In contrast, the tuple arguments `('answer', Decimal(42))` and `('answer', Fraction(42))` are treated as equivalent. The decorator also provides a `cache_clear()` function for clearing or invalidating the cache. The original underlying function is accessible through the `__wrapped__` attribute.

When Coconut compiles a `.coco` (or `.coc`/`.coconut`) file, it will compile to another file with the same name, except with `.py` instead of `.coco`, which will hold the compiled code. If an extension other than `.py` is desired for the compiled files, such as `.pyde` for [Python Processing](http://py.processing.org/), then that extension can be put before `.coco` in the source file name, and it will be used instead of `.py` for the compiled files. For example, `name.coco` will compile to `name.py`, whereas `name.pyde.coco` will compile to `name.pyde`. -### Compilation Modes +#### Compilation Modes Files compiled by the `coconut` command-line utility will vary based on compilation parameters. If an entire directory of files is compiled (which the compiler will search recursively for any folders containing `.coco`, `.coc`, or `.coconut` files), a `__coconut__.py` file will be created to house necessary functions (package mode), whereas if only a single file is compiled, that information will be stored within a header inside the file (standalone mode). Standalone mode is better for single files because it gets rid of the overhead involved in importing `__coconut__.py`, but package mode is better for large packages because it gets rid of the need to run the same Coconut header code again in every file, since it can just be imported from `__coconut__.py`. By default, if the `source` argument to the command-line utility is a file, it will perform standalone compilation on it, whereas if it is a directory, it will recursively search for all `.coco` (or `.coc` / `.coconut`) files and perform package compilation on them. Thus, in most cases, the mode chosen by Coconut automatically will be the right one. But if it is very important that no additional files like `__coconut__.py` be created, for example, then the command-line utility can also be forced to use a specific mode with the `--package` (`-p`) and `--standalone` (`-a`) flags. -### Compatible Python Versions +#### Compatible Python Versions While Coconut syntax is based off of the latest Python 3, Coconut code compiled in universal mode (the default `--target`)—and the Coconut compiler itself—should run on any Python version `>= 2.6` on the `2.x` branch or `>= 3.2` on the `3.x` branch (and on either [CPython](https://www.python.org/) or [PyPy](http://pypy.org/)). @@ -275,7 +275,7 @@ Finally, while Coconut will try to compile Python-3-specific syntax to its unive - `a[x, *y]` variadic generic syntax (use [type parameter syntax](#type-parameter-syntax) for universal code) (requires `--target 3.11`), and - `except*` multi-except statements (requires `--target 3.11`). -### Allowable Targets +#### Allowable Targets If the version of Python that the compiled code will be running on is known ahead of time, a target should be specified with `--target`.

Specifically, instead of writing ```coconut -pairs = range(1, 11) |> groupsof$(2) +seq = get_elem() :: seq ``` +which will crash due to the aforementioned Python issue, write +```coconut +@recursive_iterator +def seq() = get_elem() :: seq() +``` +which will work just fine. -**Python:** -```coconut_python -pairs = [] -group = [] -for item in range(1, 11): - group.append(item) - if len(group) == 2: - pairs.append(tuple(group)) - group = [] -if group: - pairs.append(tuple(group)) +One pitfall to keep in mind working with `recursive_iterator` is that it shouldn't be used in contexts where the function can potentially be called multiple times with the same iterator object as an input, but with that object not actually corresponding to the same items (e.g. because the first time the object hasn't been iterated over yet and the second time it has been). + +##### Example + +**Coconut:** +```coconut +@recursive_iterator +def fib() = (1, 1) :: map((+), fib(), fib()$[1:]) ``` -### `reiterable` +**Python:** +_Can't be done without a long decorator definition. The full definition of the decorator in Python can be found in the Coconut header._ + +### Built-In Types -**reiterable**(_iterable_) +#### `multiset` -`reiterable` wraps the given iterable to ensure that every time the `reiterable` is iterated over, it produces the same results. Note that the result need not be a `reiterable` object if the given iterable is already reiterable. `reiterable` uses [`tee`](#tee) under the hood and `tee` can be used in its place, though `reiterable` is generally recommended over `tee`. +**multiset**(_iterable_=`None`, /, **kwds) + +Coconut provides `multiset` as a built-in subclass of [`collections.Counter`](https://docs.python.org/3/library/collections.html#collections.Counter) that additionally implements the full [Set and MutableSet interfaces](https://docs.python.org/3/library/collections.abc.html). + +For easily constructing multisets, Coconut also provides [multiset literals](#set-literals). + +The new methods provided by `multiset` on top of `collections.Counter` are: +- multiset.**add**(_item_): Add an element to a multiset. +- multiset.**discard**(_item_): Remove an element from a multiset if it is a member. +- multiset.**remove**(_item_): Remove an element from a multiset; it must be a member. +- multiset.**isdisjoint**(_other_): Return True if two multisets have a null intersection. +- multiset.**__xor__**(_other_): Return the symmetric difference of two multisets as a new multiset. Specifically: `a ^ b = (a - b) | (b - a)` +- multiset.**count**(_item_): Return the number of times an element occurs in a multiset. Equivalent to `multiset[item]`, but additionally verifies the count is non-negative. + +Coconut also ensures that `multiset` supports [rich comparisons and `Counter.total()`](https://docs.python.org/3/library/collections.html#collections.Counter) on all Python versions. ##### Example **Coconut:** ```coconut -def list_type(xs): - match reiterable(xs): - case [fst, snd] :: tail: - return "at least 2" - case [fst] :: tail: - return "at least 1" - case (| |): - return "empty" +my_multiset = m{1, 1, 2} +my_multiset.add(3) +my_multiset.remove(2) +print(my_multiset) ``` **Python:** -_Can't be done without a long series of checks for each `match` statement.

Note that all [Sequences/Mappings/Sets](https://docs.python.org/3/library/collections.abc.html) are always assumed to be reiterable even without calling `__copy__`. +`Expected` is primarily used as the return type for [`safe_call`](#safe_call). Generally, the best way to use `Expected` is with [`fmap`](#fmap), which will apply a function to the result if it exists, or otherwise retain the error. + +##### Example + +**Coconut:** +```coconut +def try_divide(x, y): + try: + return Expected(x / y) + except Exception as err: + return Expected(error=err) + +try_divide(1, 2) |> fmap$(.+1) |> print +try_divide(1, 0) |> fmap$(.+1) |> print +``` + +**Python:** +_Can't be done without a complex `Expected` definition. See the compiled code for the Python syntax._ + +#### `MatchError` + +A `MatchError` is raised when a [destructuring assignment](#destructuring-assignment) or [pattern-matching function](#pattern-matching-functions) fails, and thus `MatchError` is provided as a built-in for catching those errors. `MatchError` objects support three attributes: `pattern`, which is a string describing the failed pattern; `value`, which is the object that failed to match that pattern; and `message` which is the full error message. To avoid unnecessary `repr` calls, `MatchError` only computes the `message` once it is actually requested. + +Additionally, if you are using [view patterns](#match), you might need to raise your own `MatchError` (though you can also just use a destructuring assignment or pattern-matching function definition to do so). To raise your own `MatchError`, just `raise MatchError(pattern, value)` (both arguments are optional). + +### Generic Built-In Functions + +#### `makedata` + +**makedata**(_data\_type_, *_args_) + +Coconut provides the `makedata` function to construct a container given the desired type and contents.

The behavior of `fmap` for a given object can be overridden by defining an `__fmap__(self, func)` magic method that will be called whenever `fmap` is invoked on that object. + +For `dict`, or any other `collections.abc.Mapping`, `fmap` will map over the mapping's `.items()` instead of the default iteration through its `.keys()`, with the new mapping reconstructed from the mapped over items. Additionally, for backwards compatibility with old versions of Coconut, `fmap$(starmap_over_mappings=True)` will `starmap` over the `.items()` instead of `map` over them. + +For [`numpy`](#numpy-integration) objects, `fmap` will use [`np.vectorize`](https://docs.scipy.org/doc/numpy/reference/generated/numpy.vectorize.html) to produce the result. + +For asynchronous iterables, `fmap` will map asynchronously, making `fmap` equivalent in that case to: +```coconut_python +async def fmap_over_async_iters(func, async_iter): + async for item in async_iter: + yield func(item) +``` + +For `None`, `fmap` will always return `None`, ignoring the function passed to it. + +##### Example + +**Coconut:** +```coconut +[1, 2, 3] |> fmap$(x -> x+1) == [2, 3, 4] + +class Maybe +data Nothing() from Maybe +data Just(n) from Maybe + +Just(3) |> fmap$(x -> x*2) == Just(6) +Nothing() |> fmap$(x -> x*2) == Nothing() +``` + +**Python:** +_Can't be done without a series of method definitions for each data type.

Thus, `ident` is effectively equivalent to: +```coconut +def ident(x, *, side_effect=None): + if side_effect is not None: + side_effect(x) + return x +``` + +`ident` is primarily useful when writing in a point-free style (e.g. in combination with [`lift`](#lift)) or for debugging [pipes](#pipes) where `ident$(side_effect=print)` can let you see what is being piped. + +### Built-Ins for Working with Iterators + +#### Enhanced Built-Ins + +Coconut's `map`, `zip`, `filter`, `reversed`, and `enumerate` objects are enhanced versions of their Python equivalents that support: + +- `reversed` +- `repr` +- Optimized normal (and iterator) indexing/slicing (`map`, `zip`, `reversed`, and `enumerate` but not `filter`) +- `len` (all but `filter`) (though `bool` will still always yield `True`) +- The ability to be iterated over multiple times if the underlying iterators can be iterated over multiple times +- [PEP 618](https://www.python.org/dev/peps/pep-0618) `zip(..., strict=True)` support on all Python versions +- Added attributes which subclasses can make use of to get at the original arguments to the object: + * `map`: `func`, `iters` + * `zip`: `iters` + * `filter`: `func`, `iter` + * `reversed`: `iter` + * `enumerate`: `iter`, `start` + +##### Indexing into other built-ins + +Though Coconut provides random access indexing/slicing to `range`, `map`, `zip`, `reversed`, and `enumerate`, Coconut cannot index into built-ins like `filter`, `takewhile`, or `dropwhile` directly, as there is no efficient way to do so. + +```coconut +range(10) |> filter$(i->i>3) |> .[0] # doesn't work +``` + +In order to make this work, you can explicitly use iterator slicing, which is less efficient in the general case: + +```coconut +range(10) |> filter$(i->i>3) |> .$[0] # works +``` + +For more information on Coconut's iterator slicing, see [here](#iterator-slicing). + +##### Examples + +**Coconut:** +```coconut +map((+), range(5), range(6)) |> len |> print +range(10) |> filter$((x) -> x < 5) |> reversed |> tuple |> print +``` + +**Python:** +_Can't be done without defining a custom `map` type.

The left argument, _x_, is the accumulated value and the right argument, _y_, is the update value from the _sequence_. If the optional _initial_ is present, it is placed before the items of the sequence in the calculation, and serves as a default when the sequence is empty.

If any exceptions are raised inside of `parallel_map`, a traceback will be printed as soon as they are encountered. Because `parallel_map` uses multiple processes for its execution, it is necessary that all of its arguments be pickleable. Only objects defined at the module level, and not lambdas, objects defined inside of a function, or objects defined inside of the interpreter, are pickleable. Furthermore, on Windows, it is necessary that all calls to `parallel_map` occur inside of an `if __name__ == "__main__"` guard. +`parallel_map` supports a `chunksize` argument, which determines how many items are passed to each process at a time. Larger values of _chunksize_ are recommended when dealing with very long iterables. Additionally, in the multi-iterable case, _strict_ can be set to `True` to ensure that all iterables are the same length. + If multiple sequential calls to `parallel_map` need to be made, it is highly recommended that they be done inside of a `with parallel_map.multiple_sequential_calls():` block, which will cause the different calls to use the same process pool and result in `parallel_map` immediately returning a list rather than a `parallel_map` object. If multiple sequential calls are necessary and the laziness of parallel_map is required, then the `parallel_map` objects should be constructed before the `multiple_sequential_calls` block and then only iterated over once inside the block. `parallel_map.multiple_sequential_calls` also supports a `max_workers` argument to set the number of processes. @@ -3681,7 +3684,7 @@ with Pool() as pool: #### `concurrent_map` -**concurrent\_map**(_function_, *_iterables_, *, _chunksize_=`1`) +**concurrent\_map**(_function_, *_iterables_, *, _chunksize_=`1`, _strict_=`False`) Coconut provides a concurrent version of [`parallel_map`](#parallel_map) under the name `concurrent_map`. `concurrent_map` behaves identically to `parallel_map` (including support for `concurrent_map.multiple_sequential_calls`) except that it uses multithreading instead of multiprocessing, and is therefore primarily useful only for IO-bound tasks due to CPython's Global Interpreter Lock. diff --git a/Makefile b/Makefile index bf772266c..0d39111b3 100644 --- a/Makefile +++ b/Makefile @@ -198,6 +198,10 @@ test-watch: clean test-mini: coconut ./coconut/tests/src/cocotest/agnostic ./coconut/tests/dest/cocotest --force --jobs 0 +.PHONY: debug-test-crash +debug-test-crash: + python -X dev ./coconut/tests/dest/runner.py + .PHONY: diff diff: git diff origin/develop @@ -214,12 +218,12 @@ docs: clean .PHONY: clean clean: rm -rf ./docs ./dist ./build ./coconut/tests/dest ./bbopt ./pyprover ./pyston ./coconut-prelude index.rst ./.mypy_cache -

For example, `name.coco` will compile to `name.py`, whereas `name.abc.coco` will compile to `name.abc`. #### Compilation Modes Files compiled by the `coconut` command-line utility will vary based on compilation parameters. If an entire directory of files is compiled (which the compiler will search recursively for any folders containing `.coco`, `.coc`, or `.coconut` files), a `__coconut__.py` file will be created to house necessary functions (package mode), whereas if only a single file is compiled, that information will be stored within a header inside the file (standalone mode). Standalone mode is better for single files because it gets rid of the overhead involved in importing `__coconut__.py`, but package mode is better for large packages because it gets rid of the need to run the same Coconut header code again in every file, since it can just be imported from `__coconut__.py`. -By default, if the `source` argument to the command-line utility is a file, it will perform standalone compilation on it, whereas if it is a directory, it will recursively search for all `.coco` (or `.coc` / `.coconut`) files and perform package compilation on them. Thus, in most cases, the mode chosen by Coconut automatically will be the right one.

Sometimes, MyPy will not know how to handle certain Coconut constructs, such as `addpattern`. For the `addpattern` case, it is recommended to pass `--allow-redefinition` to MyPy (i.e. run `coconut --mypy --allow-redefinition`), though in some cases `--allow-redefinition` may not be sufficient. In that case, either hide the offending code using [`TYPE_CHECKING`](#type_checking) or put a `# type: ignore` comment on the Coconut line which is generating the line MyPy is complaining about and the comment will be added to every generated line.

Results can be streamed one at a time when iterating by passing _stream_=`True`, however note that _stream_=`True` requires that the resulting iterator only be iterated over inside of a `process_map.multiple_sequential_calls` block (see below). Because `process_map` uses multiple processes for its execution, it is necessary that all of its arguments be pickleable. Only objects defined at the module level, and not lambdas, objects defined inside of a function, or objects defined inside of the interpreter, are pickleable. Furthermore, on Windows, it is necessary that all calls to `process_map` occur inside of an `if __name__ == "__main__"` guard. `process_map` supports a `chunksize` argument, which determines how many items are passed to each process at a time. Larger values of _chunksize_ are recommended when dealing with very long iterables. Additionally, in the multi-iterable case, _strict_ can be set to `True` to ensure that all iterables are the same length. +_Deprecated: `parallel_map` is available as a deprecated alias for `process_map`.

If multiple sequential calls are necessary and the laziness of process_map is required, then the `process_map` objects should be constructed before the `multiple_sequential_calls` block and then only iterated over once inside the block. `process_map.multiple_sequential_calls` also supports a `max_workers` argument to set the number of processes. -_Deprecated: `parallel_map` is available as a deprecated alias for `process_map`.

To avoid such situations, only nest statement lambdas inside other statement lambdas, and explicitly partially apply a statement lambda to pass in a value from a list comprehension. +Additionally, statement lambdas have slightly different scoping rules than normal lambdas. When a statement lambda is inside of an expression with an expression-local variable, such as a normal lambda or comprehension, the statement lambda will capture the value of the variable at the time that the statement lambda is defined (rather than a reference to the overall namespace as with normal lambdas). As a result, while `[=> y for y in range(2)] |> map$(call) |> list` is `[1, 1]`, `[def => y for y in range(2)] |> map$(call) |> list` is `[0, 1]`. Note that this only works for expression-local variables: to copy the entire namespace at the time of function definition, use [`copyclosure`](#copyclosure-functions) (which can be used with statement lambdas). Note that statement lambdas have a lower precedence than normal lambdas and thus capture things like trailing commas.

Thus, `match def f(xs=[]) = xs` will instantiate a new list for each call where `xs` is not given, unlike `def f(xs=[]) = xs`, which will use the same list for all calls where `xs` is unspecified. This also allows defaults for later arguments to be specified in terms of matched values from earlier arguments, as in `match def f(x, y=x) = (x, y)`. Pattern-matching function definition can also be combined with `async` functions, [`copyclosure` functions](#copyclosure-functions), [`yield` functions](#explicit-generators), [infix function definition](#infix-functions), and [assignment function syntax](#assignment-functions).

The basic syntax is +``` +case def : + match(, , ... [if ]): + + match(, , ... [if ]): + + ... +``` +where the patterns in each `match` are checked in sequence until a match is found and the body under that match is executed, or a [`MatchError`](#matcherror) is raised.

[if ]): return +``` + +`case` function definition can also be combined with `async` functions, [`copyclosure` functions](#copyclosure-functions), and [`yield` functions](#explicit-generators). The various keywords in front of the `def` can be put in any order. + +`case def` also allows for easily providing type annotations for pattern-matching functions. To add type annotations, inside the body of the `case def`, instead of just `match(...)` statements, include some `type(...)` statements as well, which will compile into [`typing.overload`](https://docs.python.org/3/library/typing.html#overload) declarations. The syntax is +``` +case def []: + type(: , : , ...) -> + type(: , : , ...) -> + ... +``` +which can be interspersed with the `match(...)` statements. + +##### Example + +**Coconut:** +```coconut +case def my_min[T]: + type(x: T, y: T) -> T + match(x, y if x <= y) = x + match(x, y) = y + + type(xs: T[]) -> T + match([x]) = x + match([x] + xs) = my_min(x, my_min(xs)) +``` + +**Python:** +_Can't be done without a long series of checks for each pattern-matching.
