Configuration in standalone setup

Hello! How can I configure this server? For example, to set the behaviour of diagnostics? I couldn't find any documentation for it.

I'm on a standalone setup, using it with coc plugin for neovim.

Thanks!

In the standard of LSP, the server obtains the configuration through Configuration.
For VSCode, the configuration is declared in package.json.
However, LSP does not specify how the language client resolves the settings, so neovim needs to refer to the package. JSON file for its own configuration.
In the future, it may be considered to parse a specific configuration file directly by the language server.

Thank you for your response!

I've found that writing

"Lua.diagnostics.disable": [
    "lowercase-global"
]

to coc-settings.json does the job in neovim with coc plugin.

Anyway, is there a place (apart from the package.json you linked above) where we can find the list of options to configure with some description explaining them? I mean, one more or less can guess the meaning of each option and the way to set it by looking at this json file, but it's much easier if there is, for instance, a wiki page for them.

But I understand it can be a big and tedious work. So it's OK if you don't have the time to write it.

Thanks again!

It's a good idea to explain the configuration options on the wiki, I will do it in these days. Thank you for your advice!

Would love to hear details about how you set things up? I am on windows and using neovim and coc @gustavo-hms, even if not on windows, please let us know.

Sure! Follow these steps:

first, if you didn't do it yet, follow these instructions to build lua-language-server as a standalone program: https://github.com/sumneko/lua-language-server/wiki/Build-and-Run-(Standalone)
open nvim
execute :CocConfig; it'll open a json file (this is the the file containing coc configuration
write the configuration for lua-language-server in that json.

For example, mine has the following json:

{
    ... many unrelated options here ...
    "languageserver": {
        "lua": {
	    "cwd": "full path of lua-language-server directory", (not sure this one is really necessary)
	    "command": "full path to lua-language-server executable",
	    "args": ["-E", "-e", "LANG=en", "[full path of lua-language-server directory]/main.lua"],
	    "filetypes": ["lua"],
	    "rootPatterns": [".git/"]
        }
    },
    "Lua.diagnostics.disable" : [
        "lowercase-global"
    ]
}

@gustavo-hms thanks for the instructions! I just tested this out locally, and when I build locally for macOS, the [full path of the lua-language-server directory] like you have mentioned doesn't have a main.lua in it, so I'm getting an error there that the file or directory doesn't exist. Should there be a main.lua there that I don't have for some reason?

Well, the [full path of the lua-language-server directory] is not the path of the executable, but the path of the base directory of the lua-language-server project (as you clone from github). So, the main.lua file refers to this file: https://github.com/sumneko/lua-language-server/blob/master/main.lua

By the way, for those interested, I also managed to configure Kakoune with kak-lsp. You have to add the following lines to ~/.config/kak-lsp/kak-lsp.toml:

[language.lua]
filetypes = ["lua"]
roots = [".git/"]
command = "full path to lua-language-server executable"
args = ["-E", "[full path of lua-language-server directory]/main.lua"]

I couldn't set lua-language-server options like the lowercase-global above though. I didn't find how.

Well, the [full path of the lua-language-server directory] is not the path of the executable, but the path of the base directory of the lua-language-server project (as you clone from github). So, the main.lua file refers to this file: /main.lua@master

ahhh duh, I interpreted that as the directory that directly contained the executable. I changed it and now it works fine. Thanks a ton!

#154 readme 添加 setting 指引

Yah I failed to get it working with coc.nvim: here is my config:

    let lua_lsp = glob('~/.local/lua-language-server')
    if len(lua_lsp)
        call coc#config('languageserver', {
            \ 'lua-language-server': {
            \     'cwd': lua_lsp,
            \     'command': lua_lsp . '/bin/Linux/lua-language-server',
            \     'args': ['-E', '-e', 'LANG="LANG=en","', lua_lsp . '/main.lua'],
            \     'filetypes': ['lua'],
            \ }
        \ })
    endif

Any suggestions, thanks

Hi, @tami5 !

I'm not on my machine right now to test your configuration, but may be you could try replacing:

       call coc#config('languageserver', {
            \ 'lua-language-server': {
            \     'cwd': lua_lsp,

with:

       call coc#config('languageserver', {
            \ 'lua': {
            \     'cwd': lua_lsp,

Tell me if it helps.

@gustavo-hms thanks so much for taking interest in my issue. same thing, here's the output of the error message

            \     'cwd': lua_lsp,

            \ }
        \ })
    endif

Hi, in vim, do we still need to do the json-schema part? Here is the output of CocInfo for me (without doing the json-schema) part.
