Typo in lua-language-server variable name, with fix

[nospam2998]

Fixed on branch: https://git.netizen.se/ale/commit/?h=fix/lua-language-server_docs

Information

VIM version

% dpkg --list vim-gtk3 | sed -n 's/^ii\s*\(\S*\s*\S*\).*/\1/p'
vim-gtk3       2:9.0.1378-2

Operating System:

% lsb_release --description 2>/dev/null 
Description:    Debian GNU/Linux 12 (bookworm)

What went wrong

Following instructions for setting luals configuration from :help ale-lua-language-server does not result in any workspace/didChangeConfiguration method call. That's unexpected.

Reproducing the bug

Place in ~/.vimrc:

let g:ale_lua_lua_language_server_config = { 'key': 'value' }

A more expected behaviour occurs if changed into:

let g:ale_lua_language_server_config = { 'key': 'value' }

Subject: [PATCH] Fix lua_language_server_config variable name

Since added in commit f2a21c9, the implementation and documentation has
differed in their naming. The latter has had an additional lua_-prefix.

With this fix, setting the variable as documented actually results in a
'workspace/didChangeConfiguration' method being executed on the luals.
