Perl regex syntax error

[mcandre]

When I try to use the Perl parser in nano-highlight, Nano complains that the regular expression syntax contains an error.

Hmm... Can you send me the exact error message? And is it just including the Perl highlighting that does it or when loading an actual Perl file?

If you need to use lookahead or lookbehind behavior inside RegEx it might call exception, when nano runs. In that situation you'd better to use RegEx like this:

color white,blue start="\$\{" end="\}"
