Following https://github.com/smallcloudai/refact-vs-classic/ , we need a first version of a plugin for Sublime Text that starts refact-lsp server, has completion, status bar, settings, and that's about it.

Completion should behave generally like in VS Code, more details about multiline and single line completion are here in a VS Classic issue and here is some more.

Clarification: this has nothing to do with completions that go inside a popup. Here we are only interested in inline completions (multiline or single line), also known as "grey text" or "ghost text".

Refact-LSP is an executable file that gets built here, download one for your platform, run it with --help to see what kind of options it accepts.

The relevant LSP part is textDocument/didOpen, textDocument/didChange, textDocument/didClose, workspace/didDeleteFiles -- to inform the LSP server about the source files open or changed. This is used for context, for a good completion for file1 probably it needs a context from file2. That's why refact-lsp needs those calls to happen.

The completion itself is a LSP call refact/getCompletions, but there's an effort to switch to a more standard 3.18.

Status bar like in this VS issue needs an idle state, rotating icon when it asks for a new completion, and an error state that shows text error in a tooltip.

Settings can be similar to VS Code settings, those are mainly go directly to refact-lsp command line. One that doesn't is "pause", it should be accessible via a context menu in the status bar or a hotkey -- an ability to pause completions if they get annoying in some cases.

This bounty supersedes the previous attempt over here that got stalled.
