Syntax highlight % and %% lines differently

jnbearon

Hi
I am creating a UDL using the GUI. I need to distinguish between lines starting with a single %, which marks a comment line, and those that start with %% which are quite different.
How do I do that please?
Thanks

Off the top of my head, the best way to do this is probably to use EnhanceAnyLexer.

^%(?!%).*$ matches any line that begins with a single %
^%%.*$ matches any line that begins with %%

In this case, you could use UDL’s own functionality by ensuring that you define two delimiters, with the %% defined first and both ending with the ((EOL)) marker.

Thanks Ekopalypse, that method does work if both are defined in “Operators and Delimiters”. What does not seem to work is to have % set as the comment marker in “Comment and Number” and %% set in the “Operators and Delimiters”. If there are consecutive lines starting with %% then they get coloured in alternating colours - seems to be something to do with how the ((EOF)) is interpreted.

I have a problem in that I am already short of Delimiter defs as the language definition form only allows 8 to be set. That then prompts 2 further questions:

Can I define more than 8 delimiters - by editing the XML file?
Can I assign more than 1 delimiter to a particular colour? (I would be quite happy to bundle a few of the less often used ones into a single colour, but have the more popular ones having their own specified coloured line.

Thanks

No. The number of colors is compiled into the program, and cannot be changed by a config file.

Yes. You can see an example of this in the “Markdown (preinstalled)” UDL that ships with Notepad++:

Just put the space-separated list of open and the space-separated list of close in the same order
