While recommended configuration for Neovim at https://termux-language-server.readthedocs.io/en/latest/resources/configure.html#neovim works it's inconvenient to use together with lspconfig. I propose to add lspconfig support for termux-language-server.
I've already implemented and tested most of it (I've no idea is it exist and if yes then how to detect a "root dir" for Android Termux and ArchLinux projects, so I leave a TODO comment there). Probably needs some polishing and then you can make a couple PRs:
- Add server configuration file to https://github.com/neovim/nvim-lspconfig/tree/master/lua/lspconfig/server_configurations
- Add mapping between lspconfig's name "termux_ls" and mason's name "termux-language-server" to https://github.com/williamboman/mason-lspconfig.nvim/blob/main/lua/mason-lspconfig/mappings/server.lua
Here is setup I've used for testing.
~/.config/nvim/lua/lspconfig/server_configurations/termux_ls.lua:
local util = require 'lspconfig.util'
return {
default_config = {
cmd = { 'termux-language-server' },
filetypes = {
-- Android Termux
'sh.build', -- build.sh
'sh.subpackage', -- *.subpackage.sh
-- ArchLinux/Windows Msys2
'sh.PKGBUILD', -- PKGBUILD
'sh.install', -- *.install
'sh.makepkg.conf', -- makepkg.conf
-- Gentoo
'sh.ebuild', -- *.ebuild
'sh.eclass', -- *.eclass
'sh.make.conf', -- /etc/make.conf, /etc/portage/make.conf
'sh.color.map', -- /etc/portage/color.map
-- Zsh
'sh.mdd', -- *.mdd
},
root_dir = function(fname)
local gentoo_repo = util.root_pattern 'profiles/repo_name'(fname)
-- TODO: Root detection for Termux and ArchLinux?
return gentoo_repo or util.find_git_ancestor(fname)
end,
single_file_support = true,
},

description = [[
Termux is a language server for some specific bash scripts.
You can install termux-language-server using mason or follow the instructions here: https://termux-language-server.readthedocs.io/en/latest/resources/install.html
The file types are not detected automatically, you can register them manually (see below) or override the filetypes:
```lua
vim.filetype.add {
extension = {
-- ArchLinux/Windows Msys2
install = 'sh.install',
-- Gentoo
ebuild = 'sh.ebuild',
eclass = 'sh.eclass',
-- Zsh
mdd = 'sh.mdd',
},
filename = {
-- Android Termux
['build.sh'] = 'sh.build',
-- ArchLinux/Windows Msys2
['PKGBUILD'] = 'sh.PKGBUILD',
['makepkg.conf'] = 'sh.makepkg.conf',
},
pattern = {
-- Android Termux
['.*%.subpackage%.sh'] = 'sh.subpackage',
-- Gentoo
['.*/etc/make%.conf'] = 'sh.make.conf',
['.*/etc/portage/make%.conf'] = 'sh.make.conf',
['.*/etc/portage/color%.map'] = 'sh.color.map',
},
}
```
]],
},
}
- Somewhere else in my configs:
vim.filetype.add {
extension = {
-- ArchLinux/Windows Msys2
install = 'sh.install',
-- Gentoo
ebuild = 'sh.ebuild',
eclass = 'sh.eclass',
-- Zsh
mdd = 'sh.mdd',
},
filename = {
-- Android Termux
['build.sh'] = 'sh.build',
-- ArchLinux/Windows Msys2
['PKGBUILD'] = 'sh.PKGBUILD',
['makepkg.conf'] = 'sh.makepkg.conf',
},
pattern = {
-- Android Termux
['.*%.subpackage%.sh'] = 'sh.subpackage',
-- Gentoo
['.*/etc/make%.conf'] = 'sh.make.conf',
['.*/etc/portage/make%.conf'] = 'sh.make.conf',
['.*/etc/portage/color%.map'] = 'sh.color.map',
},
}
- At beginning of lspconfig setup (adding our config because it's not supported officially yet):
local configs = require 'lspconfig.configs'
if not configs['termux_ls'] then
configs['termux_ls'] = require 'lspconfig/server_configurations/termux_ls'
end
local server = require 'mason-lspconfig.mappings.server'
server.lspconfig_to_package['termux_ls'] = 'termux-language-server'
server.package_to_lspconfig['termux-language-server'] = 'termux_ls'That's it, the rest of setup is usual for lspconfig.
