CMake LSP Implementation.
Alpha Stage, work in progress.
## Features
- [x] Builtin command completion
- [x] Documentation for commands and variables on hover
- [x] Formatting (by [`cmake-format`](https://github.com/cheshirekow/cmake_format))
## Commands
- `cmake-language-server`: LSP server
## Installation
```bash
$ pip install cmake-language-server
```
### Tested Clients
- Neovim ([neoclide/coc.nvim][coc.nvim], [prabirshrestha/vim-lsp][vim-lsp])
#### Neovim
##### coc.nvim
```jsonc
"languageserver": {
"cmake": {
"command": "cmake-language-server",
"filetypes": ["cmake"],
"rootPatterns": [
"build/"
],
"initializationOptions": {
"buildDirectory": "build"
}
}
}
```
##### vim-lsp
```vim
if executable('cmake-language-server')
au User lsp_setup call lsp#register_server({
\ 'name': 'cmake',
\ 'cmd': {server_info->['cmake-language-server']},
\ 'root_uri': {server_info->lsp#utils#path_to_uri(lsp#utils#find_nearest_parent_file_directory(lsp#utils#get_buffer_path(), 'build/'))},
\ 'whitelist': ['cmake'],
\ 'initialization_options': {
\ 'buildDirectory': 'build',
\ }
\})
endif
```
### Configuration
* `buildDirectory`
This language server uses CMake's file API to get cached variables.
The API communicates using `<buildDirectory>/.cmake/api/`.
`buildDirectory` is relative path to the root uri of the workspace.
To configure the build tree, you need to run the cmake command such as `cmake .. -DFOO=bar`.
