I am processing an input format that can use either @ or \ to introduce inline directives. when a literal @ or \ is in the input, either character can be used to escape either character. IE: @@ or \@ or \\ or @\
Currently, I replace the escape sequences with place holders, then extract directives, then replace the placeholders with the intended literal occurrences of @ and \ in the string.
print "Extracted code '$1'\n";
I'm sure there's a better way, but my search-foo is lacking. And so is my regex-foo. (And there's likely an input file that will break this.)
(and no, it's not LaTeX, despite the similarities)
