17:35:08BombeHmm, there doesn’t seem to be a maintained syntax highlighting library for Java. That makes me sad.
17:41:32BombeNot sure I understand. I have a String, I want some representation that allows e.g. colouring. Could be an AST, could be Markdown, could be HTML.
17:42:21BombeThat would be an acceptable outcome, yes.
17:45:40BombeMaybe my search engine skills have turned to shit, but the only thing I can find is commonmark, which doesn’t do syntax highlighting, and blogposts that list a number of syntax highlighting projects which support ~5 languagues and are unmaintained.
17:49:08BombeThe fuck, do I have to explain the difference between Java and JavaScript to you? :D
17:50:14BombeString -> (something)? -> HTML is pretty much exactly what I want to do.
17:51:19BombeClient-side is no good, though, I need it in Java.
17:51:51BombeWell, on the JVM, to be more precise, don’t care what it’s in exactly, unless it requires gigantic runtimes or is Scala. :)
17:53:08BombeI’m getting a String, I want to apply syntax highlighting, and I want to store the resulting HTML.
18:09:33ernimrilBombe, so what parts do you want help with? The tokenizer? the parser? the highlighter? the output handling?
18:14:01ernimrilBombe, depending on what you want, this can maybe be useful for a few of the above: https://github.com/bobbylight/RSyntaxTextArea

19:34:18Bombeernimri, what I would love is a library to take care of all of that for me. :D
19:35:32dreamrealconsidering the specificity of the requirement, that'd be a high expectation :D
19:35:49* sponkz joined #java
19:37:58BombeI’m not sure what is so incredibly hard to understand: I have a String, and I want a String.
19:39:00BombeThe final result will be stored; at some point in the future it will be sanitized and displayed in a browser, but that’s completely irrelevant because out of scope.
19:40:09dreamrealso you want a string, that presumably represents valid java source, to be highlighted in... html using... styles? no css?
19:40:15dreamrealno, like, external css
19:42:02dreamrealwhy not, in that case, start with a keyword search/replace: s/package/<span style="color:red">package</span>/
19:43:45dreamrealotherwise you're looking at generating an AST and using that to spit out bits based on token purpose
19:43:55dreamrealwhich is not particularly complicated, I suppose
19:44:51BombeYes, I know how (in theory) to do that manually, and if everything else is shit, I will probably do that.
19:45:03BombeStill, I would love to not do that myself. :)
