This script started from a simple necessity to run a program, multiple times, with different arguments, on Windows. Other restraints such as a no-external-dependency single-file were optional, but convenient, and they stuck until today (well, except external dependencies 🤭).
As it stands now, go.py is a needlessly large python script that finds an executable, and launches it with some arguments. (on Linux too!)
The format for any go call is:
go [go arguments...] [program name] [target arguments...]
Most go arguments revolve around reading and then processing different arguments for the target program.
In most cases, it shouldn't make any difference if you run a program with go prepended to the command line, more or less like prepending cmd /c.
Detailed help is available by running go without any arguments, or go /help.
Most features only require a standard Python 3.8+ interpreter.
However, there are a couple of optional requirements that either enhance or enable other features.
Run a program:
go calc
Run a specific program, regardless of it being found or not:
go C:\NotInPath\ayy.exe
Run a program in its directory:
go /cd cmd /c dir /b
Temporarily add an extension to the allowed list, and run a program with it:
go /ext+"bat" batchfile
Fetch all
61A3
urls listed in a file, with wget:
go /fapply-"urls.txt" wget
Use a go subcommand as an apply argument:
go /gapply-"cmd /c dir" cmd /c echo
Explicitly set apply argument position with inline markers:
go /iapply-"3,4" /iapply-"1,2" cmd /c echo %%1%% %%0%%
Generate all integers between 0 and 100, and format them as a 0 padded 3 digit number:
go /rapply-1,100+[fi:%03d] cmd /c echo
Print last 4 characters of all files in the current directory, read from stdin:
dir /b | go /papply+[ss:-4:] cmd /c echo
Print only the extensions of all files in the current directory, read from stdin; not using [^.]+ due to parsing issues:
dir /b | go /papply+[rs:\..+?$] cmd /c echo
Concatenate files using cmd's copy and go's format+flatten:
dir /b *.bin | go /asscript /papply+[f:\"%s\"]+[fl:+] copy /b %%%% out.bin
- sometimes, unicode strings perform jankily, but I am not sure how to fix this
- for example running
dir /b | go /papply cmd /c echoin a directory containing files with unicode names
- for example running
/parallelusually has weird output (but runs properly)
Most features were tested "by hand" only, and Linux support might be a bit below Windows.
This project has nothing to do with Go (the programming language).
