UltiSnips plugin for Vis editor.

This isn't an official plugin reimplementation. I am not in any way affiliated with UltiSnips developer(s).

I needed this functionality in Vis, and UltiSnips seemed powerful and mature enough, and had plenty of templates available.

How to make it work

Configuration

1. copy snippets.lua into your .config/vis/plugins directory

2. (optional) if you don't already have snippets, get them. You can clone https://github.com/honza/vim-snippets

3. in snippets.lua modify the snippetfiles value so that it points to the absolute path where you keep your UltiSnip snippets. Trailing slash is necessary

Usage

In insert mode, hit <C-j> to show vis-menu with all snippets found for the currently set syntax - it literally looks for a file in your path called <syntax>.lua. You can also pre-type the snippet tabtrigger that you're looking for.

When snippet is expanded, all of its tags will be added to the selection jumplist. You can use Vis motions g< and g> to navigate between them.

What works

You can:

• get a list of snippets per syntax
• insert the snippet
• navigate around its anchor points

What is known to not work

Temporarily

1. Multiple selections for same tag numbers (only figured out half an hour ago a solution to multiple selections)

Is unlikely to work until someone fixes it (ie. I don't care much about it right now)

1. python interpolations, date interpolations, etc etc etc

2. nested tags (correctly parsed, but not correctly inserted)

3. options

What is supposed to work but might not

• Parsing of more complex snippets. Lpeg grammar for this is quite complex (I'm looking at you, nested tags feature)

• vis-menu for one or the other reason corrupts my terminal when invoked. This might be plugin doing something its not supposed to - but I don't know what. If you do, please PR. Mind you, dmenu has no such problems.

• who knows??? This was supposed to be few hours project max, ended up being a rabbit hole!

Final notes

All of this, because muscle memory from vim made me remember I can't just insert {-# LANGUAGE ...#-} pragma via template.

And I didn't like that.

So I spent upwards of 15h writing this plugin.

Go figure.
