read content of keywords.txt for text highlights

[aster94]

hello,
arduino uses a file inside the library folder caller "keywords.txt" used to generate some highlights for the function's names, costants, class and more

please see:
https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification#keywords

here there is the arduino core keywords.txt:
https://github.com/arduino/Arduino/blob/master/build/shared/lib/keywords.txt

here an example from a library i wrote:

+1 This would be a very interesting feature 👍

VS Code seems not support dynamical syntax highlighting currently. We leave this issue in backlog and ask VS Code team if they can do something for this feature request.

What do you mean exactly with "dynamical"? Would it be possible to load it only at startup of vscode?

Arduino IDE load all the keywords.txt files only at startup, a similar behaviour would be ok

[Sneezry]

Keywords needs be pre-defined in the extension in package.json, but not load from external files.

See https://code.visualstudio.com/docs/extensionAPI/language-support#_syntax-highlighting

mmm clear, ok let's see what can be done

Just saw this as I'm currently working hard on a proper IntelliSense implementation (currently alpha testing), see #438 and my branch notes. This will become obsolete as soon as latter is integrated. keywords.txt is a dirty hack of the Arduino IDE to work around the lack of something powerful as IntelliSense.

Added it to my list of related issues.

Agree with @elektronikworkshop, IntelliSense features, which need improvement, should provide the same but better functionality than the keywords.txt file. Reactivate if there is something I'm missing in this request.
