I'm working on a C# editor and currently focusing on its syntax highlighting system.
My problem is that the overlaps are overlapping! For example:
I want to write this comment in the editor: @* double quote: " *@
But because double quote is known as the character that makes the string, the result looks like this:
And also:
Single line comment Regex code: SINGLE_LINE_COMMENTS = "@.*"
Multi line comment Regex code: MULTI_LINE_COMMENTS = @"@\*.*?(\*@|$)"
And finally string Regex code:
STRINGS = @"(\\|f|\\f|f\\)?\s*(""""|""(.|\\"")*?([^\\]""|$)|''|'(.|\\')*?([^\\]'|$))"
I know, its a little bit of monster. But this is what it is (and its also supports ' and " for strings, like python). If you want more explanation about it, I can explain.
Also, this is a code that C# finds Regex.Matches (for comments and strings):
MatchCollection singleLineComments = Regex.Matches(code_section.Text, SINGLE_LINE_COMMENTS);
MatchCollection multiLineComments = Regex.Matches(code_section.Text, MULTI_LINE_COMMENTS, RegexOptions.Singleline);
MatchCollection strings = Regex.Matches(code_section.Text, STRINGS, RegexOptions.Singleline);
And finally for highlighting, I loop through each one of MatchCollections and highlight the code section that I want to be highlighted
I want to say: Is there a way in C# or Regex (maybe) to say, for example: If it was in the comment section, don't apply the string highlighting and stuff like that.
