Looks like most ST extension authors are now moving to vscode. There seems to be fewer and fewer extensions that work 
quite unfortunate as Iāve just recently bought my copy.
Are there any not-too-technical documentation on creating ST plugins? Particularly with regards to syntax highlighting? Iād like to update an existing codebase for nunjucks syntax.
Iām not sure what makes it look ālike most ST extension authors are now moving to vscodeā. New packages are submitted at a rate of several per week.
Here is the syntax definition documentation.
It looks like the existing Nunjucks package was only maintained for a short time and has been abandoned for years. It also looks like that syntax definition is based on a very old version of the core HTML definition. If I were you, Iād start from scratch rather than trying to extend the old syntax.
If you do create a better Nunjucks package, and the author of the original agrees, the āNunjucksā name in Package Control can be moved to point to the newer package instead.
Iām publishing many of my packages for three platforms: Sublime Text, Atom and Visual Studio Code. There are many features I like (and prefer) in the latter two, both from a userās and a package developerās point of view. Visual Studio Code has some amazing features, Atom has the most powerful API. However, since performance matters to me, so I still use Sublime Text for all my projects.
Iām only publishing for Sublime Text at the moment because of lack of time. I also am not a fan of Atom or VS Code because theyāre so slow compared to Sublime Text. And Notepad++ had memory leaks in most of the plugins I use and I donāt feel like porting to it at the moment especially since it doesnāt support threading natively ( searching in file causes the entire application to lock up for minutes at a time ).
I do like Atom and VS Code for supporting advanced panels because it provides more options - but Sublime Text supports Python meaning you can use TKInter and create your own panels and use a networking or other communication package to transfer the data between sublime text and backā¦ I may end up going this route because itād provide a more uniform setup and less bloatā¦ Weāll seeā¦
you can use jinja2 syntax definition for nunjucks, or twig syntax. and itās fine
i have merged both in one file and had some customization, and it looks like in my theme(but theme is customized too)
