Vim syntax file for Sway

Installation

Pre-requisites:

1. Clone this repo
2. Ensure you have the forc-lsp binary with which forc-lsp. If not, install the Sway toolchain.

Neovim

1. Copy the folders 'ftdetect' and 'syntax' to the config folder:

   cp -R ~/sway.vim/syntax ~/.config/nvim && cp -R ~/sway.vim/ftdetect ~/.config/nvim

2. If you do not have ~/.config/nvim/init.lua, install kickstart.nvim.
3. If you already have init.lua, you may need to require extra dependencies, or simply copy this block.
4. Add the following to ~/.config/nvim/init.lua:

   
   -- Install Sway LSP as a custom server
   local lspconfig = require 'lspconfig'
   local configs = require 'lspconfig.configs'

-- Check if the config is already defined (useful when reloading this file) if not configs.sway_lsp then configs.sway_lsp = { default_config = { cmd = {'forc-lsp'}, filetypes = {'sway'}, on_attach = on_attach, init_options = { -- Any initialization options logging = { level = 'trace' } }, root_dir = function(fname) return lspconfig.util.find_git_ancestor(fname) end; settings = {}; }; } end

lspconfig.sway_lsp.setup{}

4. Check that the LSP is running by running `:LspInfo` and trying out features like Goto Definition (`gd`) and Hover (`K`). The key mappings are defined in `~/.config/nvim/init.lua`

1. Clone this repo
2. Copy the folders 'ftdetect' and 'syntax' to the config folder: 

cp -R ~/sway.vim/syntax ~/.vim && cp -R ~/sway.vim/ftdetect ~/.vim

3. Edit your `~/.vim/filetype.vim` to contain the following block:

if exists("did_load_filetypes") finish endif

augroup filetypedetect au! BufNewFile,BufRead *.[sS][wW] setf sway augroup END

4. Install [plug.vim](https://github.com/junegunn/vim-plug)
5. Add the following to your `~/.vimrc`

call plug#begin()

Plug 'prabirshrestha/vim-lsp'

6. Create a file called `~/.vim/lsp.vim` with the following contents, or add this to an existing vim script:

" vim-lsp for Sway (sway-lsp) if executable('sway-lsp') au User lsp_setup call lsp#register_server({ \ 'name': 'sway-lsp', \ 'cmd': {server_info->['sway-lsp']}, \ 'whitelist': ['sway'], \ }) endif

7. Open vim and `:source ~/.vim/lsp.vim`
8. Check that the LSP is running with `:LspStatus` and try out feature like `:LspDefinition` and `:LspHover`. The full list of commands are defined [here](https://github.com/prabirshrestha/vim-lsp).
