I know Nim already can do this (from documentation):
line =~ re"\s*(\w+)\s*\=\s*(\w+)":
# matches a key=value pair:
echo("Key: ", matches[0])
echo("Value: ", matches[1])
elif line =~ re"\s*(\#.*)":
# matches a comment
# note that the implicit ``matches`` array is different from the
# ``matches`` array of the first branch
echo("comment: ", matches[0])
else:
echo("syntax error")What about the following syntax for regex substitution? Can it be emulated with macros ou added to the core language?
string =~ s/regex/replacement/g;
It would be great to have regex syntax sugar in the core language. That would make Nim even more practical, while still remaining readable.
