--- Expert is the official language server implementation for the Elixir programming language.
|
|
---
|
|
--- 'root_dir' is chosen like this: if two or more directories containing `mix.exs` were found when
|
|
--- searching directories upward, the second one (higher up) is chosen, with the assumption that it
|
|
--- is the root of an umbrella app. Otherwise the directory containing the single mix.exs that was
|
|
--- found is chosen.

root_dir = function(bufnr, on_dir)

local fname = vim.api.nvim_buf_get_name(bufnr)
|
|
--- Elixir workspaces may have multiple `mix.exs` files, for an "umbrella" layout or monorepo.
|
|
--- So we specify `limit=2` and treat the highest one (if any) as the root of an umbrella app.
|
|
local matches = vim.fs.find({ 'mix.exs' }, { upward = true, limit = 2, path = fname })
|
|
local child_or_root_path, maybe_umbrella_path = unpack(matches)
|
|
local root_dir = vim.fs.dirname(maybe_umbrella_path or child_or_root_path)
