add to dictionary action in ltex-ls language server

[smason]

Just wondering if the "Add ... to dictionary " code action work for other people?

I've just configured helix to use this language server, and it's flagging some technical words. I tried using the above action which silently fails. Setting the log file:

[[language]]
name = "markdown"
language-server = { command = "ltex-ls", args=["--log-file=/tmp"] }

allowed me to see:

{"jsonrpc":"2.0","method":"workspace/executeCommand","params":{"arguments":[{"uri":"file:///home/smason/foo.md","words":{"en-US":["Smalltalk"]}}],"command":"_ltex.addToDictionary"},"id":13}

{"jsonrpc":"2.0","id":13,"result":{"success":false,"errorMessage":"Unknown command \u0027_ltex.addToDictionary\u0027, ignoring"}}

which suggests the problem could be in ltex-ls, but thought I should try here first

It does not work as it needs to be implemented in Helix. It is the same situation in Neovim, it is not implemented there yet either. I have made my own workaround in Neovim:

-- add vim user dictionary for ltex-ls
local path = vim.fn.stdpath 'config' .. '/spell/en.utf-8.add'
local words = {}

for word in io.open(path, 'r'):lines() do
  table.insert(words, word)
end

lspconfig.ltex.setup {
  on_attach = on_attach,
  capabilities = capabilities,
  settings = {
    ltex = {
      -- additionalRules = {
      --   languageModel = '~/ngrams/',
      -- },
      disabledRules = {
        ['en-US'] = { 'PROFANITY' },
        ['en-GB'] = { 'PROFANITY' },
      },
      dictionary = {
        ['en-US'] = words,
        ['en-GB'] = words,
      },
    },
  },
}

Would love to see "Add ... to dictionary " added to Helix!

that sounds weird, but does indeed seem to be how they expect things to work:

Some commands are handled by LTEX LS, while others must be handled by the language client. This is in contrast to the LSP specification, which recommends that the server handles all commands.

I'm also unsure how I pass settings to the language server so I can work around this manually.

To pass setting to the language server in Helix use config = { }, for example: config = { "provideFormatter" = true }. If you get anything interesting going on plz post it here :)
