I'm a new Geany user. First, thanks all developers for your hard work on a great program. The editor is amazing!

My question is about what Geany automatically does when a single quote character (') is placed in front of a word and if its possible to control that behavior. I ask because one language I'm currently developing in is Maxima and the single quote is an operator (prevents evaluation).

For my colorscheme=zenburn.conf and lexer_filetype=C, when I type a single quote before a word, it italicizes the rest of the current line, and changes all colors to a light red (overwriting any colors per primary and secondary keywords I have defined in my filetypes.Maxima.conf)

Are there any settings / knobs I can turn to modify this behavior, such as lexer_properties or settings, in the filetypes.*.conf file? Preferably, I'd like to avoid writing my own lexer file to make this small change; but if its necessary, I'd appreciate some advice on how and where to make that change in the src.

Syntax highlighting is controlled by a lexer written in C++ that identifies syntactic elements. You have selected to use the C language lexer where single quotes identify character literals.

You should try other languages, but most use single quote as a character sequence opening. Perhaps Lisp would be more useful since single quote has a similar meaning in Lisp to Maxima (and come to think of it I believe Maxima is written in Lisp)..

You could create a colour scheme that sets the styling for characters to something neutral, but nothing in the rest of the line (or at least to the next single quote, that being what C requires to close a character) will be syntactically analysed since the lexer thinks its a character literal.

For anything else you would have to change the lexer to stop it identifying characters when it encounters a single quote. The lexer is part of the Scintilla editing widget Geany uses and is in the scintilla directory.

Thanks!
