Is there a text editor that would allow me to create syntax highlighting easily?
Is there a text editor that would allow me to create syntax highlighting easily?
Basically just the title said. The situation is basically I use a Domain-Specific Language called G'MIC, and to this day, I haven't found a satisfactory answer to the issue of lack of syntax highlighting. At the moment, I am using KDE Kate as it's pretty good at structuring the code with their find/replace feature, tab indicators, and multi-window support.
You're viewing a single thread.
What is stopping you from creating a syntax highlight file for Kate? I remember it as one of the more comfy formats.
I actually did that, but it was not satisfactory. And I had hard time making it work like how I want to.
Maybe I should use a XML editor or something to make it easier. I'll give it another try (I just found the file again). Maybe from scratch even.
EDIT: To make it clear, I have hard time getting "contexts" working.
To make it clear, I have hard time getting “contexts” working.
Are there any particular problems?
However, if you're using Windows/have Wine installed and feel that contexts are an overkill, there is Notepad++' User Defined Languages, which as far as I can tell is purely based on lexemes.
Getting highlighting for regex-based selection to work. That seems confusing. I have 7 criterias which is recommended for the G'MIC language.
Note:
- Strings that matches
#( |$|(#)+).*gets treated as if it was a comment. - Strings that matches
#@cli.*are treated as if they’re a header for CLI codes. - Strings that matches
\$(-\d+|\w+|\d+)gets treated as if they’re accessed variables. - Strings that matches
\w+:are treated as if they’re commands names. - Any texts under control-flow item list gets highlighted as long as they’re outside any characters between 2 quotation marks and of course, taking into account of / being used as escape character.
#@guigets bolded.- Anything between 2 quotation marks gets highlighted though escape characters would be considered.
That looks odd and I'm somehow unable to find convincingly representative gmic scripts. Maybe those other highlighter files could help? https://kate-editor.org/syntax/
I have a update for you, I am finally pulling it off!

There will be problems down the road, but I will worry about that later.
Nice job! Which was the most challenging part?
So far, the most challenging part was highlighting things that counts as comment rather than pointers to image pixels or accessible variables. That's not the end of my trouble though.
I do want to figure out how to highlight "expr" including newlines inside expr. expr is basically any mathematical expression that is utilized on JIT compilation.
- if expr
- repeat expr
- variable={expr}
- variable:=expr <- : can be replaced with operator and it will still apply.
- eval expr
- eval "expr"
- check "expr"
- fill expr
- fill "expr"
- eval>expr
- eval >"expr"
- fill >expr
- fill >"expr"
- {expr}
- for expr
- {"expr"}
- while expr
Along with that to set up regex inside it to highlight section of expr.
While still maintaining priority of regex. So, if one regex is more important, it'll overwrite whatever highlighted.
Was that what modes are for?
What do you mean? I'm pretty new to making syntax highlighting for KDE Kate, so I'm just now fixing my other thing before I get into much more advanced concept of it.
The way I remember stuff and it seems to be explained in here a context is a way to limit the amount of checked regexes. So as I understand you can start an expr context if you hit one of those keywords. Kind of like modes in XSL or working with a stack.
That document also describes how to handle newlines in context.
There's no standard regarding G'MIC scripting. That being said, here's a representative G'MIC script - https://pastebin.com/cEPW31HJ .
The first one is basically a example script for testing syntax highlighting. The second one is a real world case study. The second one can be found in https://github.com/GreycLab/gmic-community/blob/master/include/reptorian.gmic .
I haven't included some concepts in the example_cli as you can see that reptorian.gmic introduces some concepts not seen in both. Basically, writing a syntax highlighter for G'MIC would be a nightmare. But doable if I can figure things out.
