snippet support

[skewballfox]

not exactly a feature request, more of request to implement a feature (or whether to wait until extensions are supported).

I've been working on what I hope will be a cross editor snippet manager (link to project) where the client and server are written in rust. while I'm looking to support a few features not covered in the specification (hoping to achieve eventual feature parity with ultisnips), the syntax I'm working to support is a superset of the syntax defined in the lsp specification.

even with support for only basic dynamic snippets(ie vscode snippets), a major usecase is reducing the amount of effort to support snippets by emerging editors to defining the interface (similar to the benefit of the LSP).

the project is at the point to where I can get completions per keystroke and insert/navigate snippets in vscode, but I'm depending on features specific to vscode. Working to support vscode first is also slowing me down because I really dislike/suck with javascript.

I'm aware that extension support is ongoing, but this also might be supportable by the editor itself (I'm trying to make it to where client implementation should be very little code) and also would make sense to a certain degree given that, while no language server (that I know of) handles snippets, snippets are a part of the LSP specification.

Hi! sniper sounds like a very interesting project!

I assume @archseer's intention was to support LSP snippets natively so I don't know if sniper support will be a built-in feature (it is also obviously very young). At any rate, I hope we can at least see a plugin for that at some point hence the A-plugin label.

Regarding an eventual built-in support, if @archseer is favorable, you may want to get involved with helix development. Don't hesitate to drop in for a chat at Helix community Helix Space 😄

I think it's worth looking at the-way for inspiration.

While all these snippets managers are nice, I think they should be implemented as a plugin.

Regarding an eventual built-in support

It could be helpful to have simple built-in snippet support like vscode snippet:). Perhaps we can have a go at this?

edit: I did have a go that (#1178), aiming to support LSP snippet. It's far from complete but now we at least know what difficulties we might encounter if we eventually try to implement snippet inside helix-core, and whether we should leave it to a plugin of some sort.

Strongly need this feature. are there any alternatives?

You can implement it and send us a PR?
