Get text from diagnostic for vimscript

[otavioschwanck]

Hi,

at first, thanks for your attention.

I want to build a feature that get the text on the diagnostic, parse and insert at the end.

Example:

I want to pick the [Layout/IndentationConsistency] from the tooltip and insert at the end of the line with some text. At final:

before_action :populate_form, only: [:new_boleto, :create_boleto] # rubocop:disable Layout/IndentationConsistency

I have no clue of how to do this on vimscript. Im a ex emacs user and have this on my configuration.

Thanks for your attetion!

:h g:coc_last_float_win, :h winbufnr(), :h getbufline(), :h setline() or :h nvim_buf_set_text() (neovim > =0.6.1)

But it's better to create a simple coc extension for that.

[chemzqm]

const {diagnosticManager, workspace, Position, commands, TextEdit} = require('coc.nvim')

exports.activate = async context => {
  let {nvim} = workspace
  context.subscriptions.push(commands.registerCommand('rubocop.comment', async () => {
    let [pos, line, bufnr] = await nvim.eval('[coc#util#cursor(),getline("."),bufnr("%")]')
    let diagnostics = await diagnosticManager.getCurrentDiagnostics()
    if (diagnostics.some(d => d.message.includes('Inconsistent indentation'))) {
      // add comment
      let doc = workspace.getDocument(bufnr)
      let edit = TextEdit.insert(Position.create(pos.line, line.length), '# rubocop:disable Layout/IndentationConsistency')
      await doc.applyEdits([edit])
    }
  }))
}

Save the javascript to a js file in your ~/.vim/coc-extensions folder.

It would be better to use languages.registerCodeActionProvider() api, so it can be fixed by <Plug>(coc-fix-current)

i use neovim, where i put this JS file?

Just found already where to put, but the rubocop.comment has no action on the buffer.

My code:

const {diagnosticManager, workspace, Position, commands, TextEdit} = require('coc.nvim')

exports.activate = async context => {
  let {nvim} = workspace
  context.subscriptions.push(commands.registerCommand('rubocop.comment', async () => {
    let [pos, line, bufnr] = await nvim.eval('[coc#util#cursor(),getline("."),bufnr("%")]')
    let diagnostics = await diagnosticManager.getCurrentDiagnostics()
    if (diagnostics.some(d => d.message.includes('rubocop'))) {
      // add comment
      let doc = workspace.getDocument(bufnr)
      let edit = TextEdit.insert(Position.create(pos.line, line.length), diagnostics[0])
      await doc.applyEdits([edit])
    }
  }))
}

i think the textedit insert part is not working

[chemzqm]

Use pos[0] instead

      let edit = TextEdit.insert(Position.create(pos[0], line.length), '# rubocop:disable Layout/IndentationConsistency')

[otavioschwanck]

.some(d => d.message.includes('rubocop'))

I ended doing that:

const {diagnosticManager, workspace, Position, commands, TextEdit} = require('coc.nvim')

exports.activate = async context => {
    let {nvim} = workspace
    context.subscriptions.push(commands.registerCommand('rubocop.insert', async () => {
        let [, line, ] = await nvim.eval('[coc#util#cursor(),getline("."),bufnr("%")]')

        let diagnostics = await diagnosticManager.getCurrentDiagnostics()

        if (diagnostics.length > 0) {
            let message = diagnostics[0].message.split(" ")[0]
            let parsedMessage = message.substr(1, message.length - 2)

            if (line.includes("# rubocop:disable")) {
                await nvim.call('setline', ['.', line + ", " + parsedMessage])
            } else {
                await nvim.call('setline', ['.', line + " # rubocop:disable " + parsedMessage])
            }
        }
    }))
}

Worked like a charm!

Thanks!
