Rogue strings are always stored internally as UTF-8.
"double-quote literal string"
'single-quote literal string'
''two-quote literal string''
@|verbatim
|string
|...
$fileString("filepath")
- A
'single-quote literal string'must have more than one character or else it will be treated as a Character instead of aString. - Verbatim Strings include everything exactly as typed. Escape characters have no effect.
- A file string creates a literal string from a specified file at compile time. To dynamically load a string from a file at runtime, use
String(File("filepath")).
Formatted strings are a way of easily building strings containing a mix of literal characters and variable values. The syntax is:
"literal string format with $ markers" (arg1,...)
Each $ marker is replaced with the corresponding argument.
local x=3, y=4
println "($,$)" (x,y+2) # prints: (3,6)
println "The cost is $$." ('$',dollars)
# There is no escape for expressing a literal '$' in a formatted string;
# you must use a '$' as an argument or string concatenation.
- You cannot use a string variable as the format because the underlying code transformation happens at compile time, not runtime.
