format for LanguageID not supported: yaml

[horseinthesky]

Here is my efm.lua:

local M = {}

M.luafmt = {
  formatCommand = "luafmt -i 2 --stdin",
  formatStdin = true
}

M.flake8 = {
  lintCommand = "flake8 --ignore=E501 --stdin-display-name ${INPUT} -",
  lintStdin = true,
  lintIgnoreExitCode = true,
  lintFormats = {"%f:%l:%c: %m"}
}

M.isort = {
  formatCommand = "isort -",
  formatStdin = true
}

M.autopep8 = {
  formatCommand = "autopep8 --ignore E501 -",
  formatStdin = true
}

M.yapf = {
  formatCommand = "yapf",
  formatStdin = true
}

M.black = {
  formatCommand = "black --quiet -",
  formatStdin = true
}

M.mypy = {
  lintCommand = "mypy --show-column-numbers --ignore-missing-imports",
  lintFormats = {"%f:%l:%c: %trror: %m", "%f:%l:%c: %tarning: %m", "%f:%l:%c: %tote: %m"}
}

M.prettier = {
  formatCommand = "prettier --stdin-filepath ${INPUT}",
  formatStdin = true
}

return M

And hehe is lsp config:

local efm = require "efm"
local flake8 = efm.flake8
local isort = efm.isort
local black = efm.black
local mypy = efm.mypy
local luafmt = efm.luafmt
local prettier = efm.prettier

local languages = {
  python = {isort, flake8, black, mypy},
  lua = {luafmt},
  yaml = {prettier},
  json = {prettier},
  html = {prettier},
  css = {prettier},
  markdown = {prettier}
}

When I try to run lua vim.lsp.buf.formatting() on the file bla.yml:

bla:
  a: 1
    b: 2
    c: 3

I get RPC[Error] code_name = unknown, code = 0, message = "format for LanguageID not supported: yaml" message.

The same prettier formatter works great for JSON.

~~I'm having exactly the same issue.~~ Update: Seems I had installed efm-langserver via Homebrew and then again via lspinstall plugin. Removing the Homebrew install and restarting cleared the issue for me.

try installing pritterd or stylua manully with Mason and config accordingly say in lspsaga.nvim.

Not relevant anymore. Disregard.
