A Language Server for Lua code, written in Lua.
It's still a work in progress, but it's usable for day-to-day. It currently supports:
- Limited autocompletion
- Goto definition
- As you type linting and syntax checking
- Code formatting
- Supports Lua 5.1-5.3 and Luajit
lua-lsp can be installed using luarocks:
$ luarocks install --server=http://luarocks.org/dev lua-lsp
This will install the
lua-lsp command. Language clients can then communicate
with this process using stdio as a transport. See editors.md for
more instructions specific to your editor of choice.
lua-lsp automatically integrates with common lua packages, when they are installed. For linting, install luacheck:
$ luarocks install luacheck
For code formatting, we currently support Formatter and LCF. Formatter is 5.1 only, whereas lcf is 5.3 only. 5.1:
$ luarocks-5.1 install Formatter $ luarocks-5.3 install lcf
If you have another package you'd like to see integrated, feel free to leave an issue/PR. Other plugins are always welcome, especially if they provide materially different results.
if lua-cjson is installed, we will optionally use it for a speed boost. It is unfortunately not supported by all versions of lua at the moment, but as soon as it is we will switch to making it mandatory.
$ luarocks install lua-cjson
lua-lsp reads a few project-level configuration files to do its work.
To configure linting, we read your standard .luacheckrc file.
For autocomplete support, we reimplement the .luacompleterc format
created by atom-autocomplete-lua. In particular, we need
properly understand your code.
More LSP-specific configuration flags will hopefully be provided through your editor's configuration support.
The LSP spec is big, and we don't implement all of it. here's a quick wishlist ordered by roughly by priority/feasibility.
