Setup plugin

[vsherratt]

Initial setup of a plugin

• Automatic detection in ftdetect/cylc.vim
• Current syntax file copied to syntax/cylc.vim
  • New syntax group cylcMultiString for triple-quoted strings, which is linked to String, unlike single-quoted strings which are not highlighed at all
• Simple local settings in ftplugin/cylc.vim (for :filetype plugin)
• Recommended indentation in indent/cylc.vim (for :filetype indent)

Check List

• I have read CONTRIBUTING.md and added my name as a Code Contributor.
• Contains logically grouped changes (else tidy your branch by rebase).

This is great, thanks!

Tested using vim-plug and NeoVim v0.7.2.

call plug#begin()
Plug 'vsherratt/cylc.vim', {'branch': 'setup-plugin'}
call plug#end()

Opened a PR to update the docs to point at this plugin: cylc/cylc-doc#624

[vsherratt]

Sorry I totally left this hanging - just reminded by recent prompts for people to get set up with cylc 8. I didn't realise how long it had been!

I'll address the existing comments shortly, and have a look for if the original syntax file has moved on at all. (Unless you're already aware of any changes and can easily point them out?)

[oliver-sanders]

No probs, thanks for contributing this.

Apologies, my vim script abilities aren't good enough to help out properly.

Not much has happened to the syntax file in the Cylc repo, main changes:

• support the ".cylc" file extension
• improvements to Jinja2 lexing (see also the PR).

I'll try to do a quick review too once you're done @vsherratt

Thanks for contributing this!

Pathogen seems a bit dead looking (note on the project saying not to use it).

Possibly replace with vim-plug:

Suggested change

	Otherwise, use your favourite plugin manager, such as
	[pathogen.vim](https://github.com/tpope/vim-pathogen).
	Otherwise, use your favourite plugin manager, such as
	[vim-plug](https://github.com/junegunn/vim-plug):
	`Plug 'cylc/cylc.vim'`

The note on pathogen is not because it's dead per se, it's because its behaviour is so close to vim 8's package management that you might as well use that. That's what I like it for: it backports that functionality. Could still make more sense to mention vim-plug than that, not sure...
