Use the Flux LSP with Vim

This page documents an earlier version of InfluxDB. InfluxDB v2.7 is the latest stable version. View this page in the v2.7 documentation.

Requirements

• Vim 8+
• npm

Install the Flux plugin

There are many ways to install and manage Vim plugins. We recommend either of the following two methods:

• Install with vim-lsp
• Install with vim-coc

Both methods require you to add the following to your .vimrc so that Vim can recognize the .flux file type:

" Flux file type
au BufRead,BufNewFile *.flux        set filetype=flux

Install with vim-lsp

1. Install flux-lsp-cli with npm

   npm i -g @influxdata/flux-lsp-cli

2. Install vim-lsp

   If it doesn’t exist yet, create a directory called pack/$USER/start/ in your ~/.vim/ and clone vim-lsp into it:

   cd ~
   mkdir -p .vim/pack/$USER/start/
   cd .vim/pack/$USER/start/
   git clone https://github.com/prabirshrestha/vim-lsp

3. Edit your .vimrc

   Next, edit your .vimrc configuration file to include the following:

   let g:lsp_diagnostics_enabled = 1
   if executable('flux-lsp')
       au User lsp_setup call lsp#register_server({
           \ 'name': 'flux lsp',
           \ 'cmd': {server_info->[&shell, &shellcmdflag, 'flux-lsp']},
           \ 'whitelist': ['flux'],
           \ })
   endif
   autocmd FileType flux nmap gd <plug>(lsp-definition)

Install with vim-coc

1. Install flux-lsp-cli from npm

   npm i -g @influxdata/flux-lsp-cli

2. Install plug-vim

   Install plug-vim, a plugin manager for Vim.

3. Install vim-coc

   Install vim-coc, a code-completion plugin for Vim.

4. Configure vim-coc

   vim-coc uses a coc-settings.json located in your ~/.vim/ directory. To run the Flux LSP, add the Flux section under languageserver:

   {
     "languageserver": {
         "flux": {
           "command": "flux-lsp",
           "filetypes": ["flux"]
         }
     }
   }

   To debug flux-lsp, configure it to log to /tmp/fluxlsp:

   {
     "languageserver": {
         "flux": {
           "command": "flux-lsp",
           "args": ["-l", "/tmp/fluxlsp"],
           "filetypes": ["flux"]
         }
     }
   }
