---
|
||||
--- Deno's built-in language server
|
||||
---
|
||||
--- To appropriately highlight codefences returned from denols, you will need to augment vim.g.markdown_fenced languages
|
||||
--- in your init.lua. Example:
|
||||
---
|
||||
--- ```lua
|
||||
--- vim.g.markdown_fenced_languages = {
|
||||
--- "ts=typescript"
|
||||
--- }
|
||||
--- ```
|
||||
---
|
||||
--- Some care must be taken here to correctly infer whether a file is part of a Deno program, or a TS program that
|
||||
--- expects to run in Node or Web Browsers. This supports having a Deno module that is a part of a mostly-not-Deno
|
||||
--- monorepo. We do this by finding the nearest package manager lock file, and the nearest deno.json or deno.jsonc.
|
||||
--- Note that this means that without a deno.json, deno.jsonc, or deno.lock file, this LSP client will not attach.
|
||||
---
|
||||
--- Example:
|
||||
---
|
||||
--- ```
|
||||
--- project-root
|
||||
--- +-- node_modules/...
|
||||
--- +-- package-lock.json
|
||||
--- +-- package.json
|
||||
--- +-- packages
|
||||
--- +-- deno-module
|
||||
--- | +-- deno.json
|
||||
--- | +-- package.json <-- It's normal for Deno projects to have package.json files!
|
||||
--- | +-- src
|
||||
--- | +-- index.ts <-- this is a Deno file
|
||||
--- +-- node-module
|
||||
--- +-- package.json
|
||||
--- +-- src
|
||||
--- +-- index.ts <-- a non-Deno file (ie, should use ts_ls or tsgo)
|
||||
--- ```
|
||||
---
|
||||
--- From the file being edited, we walk up to find the nearest package manager lockfile. This is PROJECT ROOT.
|
||||
--- From the file being edited, find the nearest deno.json or deno.jsonc. This is DENO ROOT.
|
||||
--- From the file being edited, find the nearest deno.lock. This is DENO LOCK ROOT
|
||||
--- If DENO LOCK ROOT is found, and PROJECT ROOT is missing or shorter, then this is a deno file, and we attach.
|
||||
--- If DENO ROOT is found, and it's longer than or equal to PROJECT ROOT, then this is a Deno file, and we attach.
|
||||
--- Otherwise, we abort, because this is a non-Deno TS file.
