Vim syntax files

[araspik]

SDLang is awesome, but I found no support for it in (Neo)Vi(m). As such, I took 2 hours to write it. Use it as you want, consider it public domain. Please publish this on the site as a useful add-on. Note that it is buggy and you want someone who's better at Vim syntax-ing to take a look at it, but it is a solid start. sdlang.zip

@araspik mind creating a separate GH repo?

[s-ludwig]

@araspik I'll add a link to the attachment for now, would indeed be great, though to have a repository link instead, where possible fixes would show up.

BTW, I've seen that you have a written D and Rust parsers - do you consider them stable enough to also be added to the list of implementations?

[araspik]

@s-ludwig Unfortunately (as you probably have seen) I haven't worked on either of the parsers in quite a while. I will, however, look back at the Rust parser (and if I can complete/improve the Rust parser, then maybe the D parser too). However, from what I remember, neither of the parsers are complete. I will look back at it.

Better SDLang vim syntax file, fixed bugs with boolean recognised as tags and strings being greedy ("this" is "still string" - all was recognised as string):

" quit when a syntax file was already loaded
if exists("b:current_syntax")
  finish
endif

syn case match

" boolean
syn keyword sdlangBool true false on off null
high def link sdlangBool Boolean

" tags
