Setting environment variable PRETTIERD_DEFAULT_CONFIG doesn't appear to do anything

[petertriho]

.prettierrc.json

{
    "tabWidth": 4,
    "overrides": [
        {
            "files": [
                "*.yaml",
                "*.yml"
            ],
            "options": {
                "tabWidth": 2
            }
        }
    ]
}

Running cat /tmp/test.yaml | prettierd test.yaml (PRETTIERD_DEFAULT_CONFIG environment variable set to where .prettierrc.json is located) doesn't work but when test.yaml is in same directory as .prettierrc.json it works

Also doesn't work when I use the same config as https://github.com/fsouza/prettierd#editor-integration for efm-langserver + neovim lsp

Changed to using $HOME instead of ~ fixed this for me

@petertriho Sorry for the noob question... but how did you set the environment variable?

[fsouza]

Hi @zeitchef, it depends on what you're using to invoke prettierd. If you're using efm + lua + nvim-lsp, you'd need something like this:

local prettier = {
  formatCommand = 'prettierd ${INPUT}',
  formatStdin = true,
  env = {
    'PRETTIERD_DEFAULT_CONFIG=/home/myuser/.config/nvim/utils/linter-config/.prettierrc.json',
  },
}

(this was adapted from the readme)

@fsouza Thanks for your speedy response! I'm trying to use formatter.nvim and it's somehow not clear how to set it this way. I've tried a shell environment variable, but should it be in a global npm env? Somehow my results are exactly as described above, it only works if my config is in the same directory.

Can you try the following (untested):

require('formatter').setup({
  logging = false,
  filetype = {
    javascript = {
        -- prettierd
       function()
          return {
            exe = "env",
            args = {"PRETTIERD_DEFAULT_CONFIG=<full-path>", "prettierd"; vim.api.nvim_buf_get_name(0)},
            stdin = true
          }
        end
    }
    -- other formatters ...
  }
})

(assuming you're on Linux/MacOS/WSL/some unix flavor, I don't think that would work on Windows)

Thanks @fsouza - this didn't seem to work for me, but it could well be a problem with formatter.nvim as I was getting some error from the plugin.

I'd rather integrate with efm anyway, so using your updated example in the README, this is how I'm setup:

// efm/prettierd.lua
return {
  formatCommand = 'prettierd ${INPUT}',
  formatStdin = true,
  env = {
    string.format('PRETTIERD_DEFAULT_CONFIG=%s', vim.fn.expand('~/.config/prettierd/.prettierrc.json')),
  }
}

// efm.lua
local prettierd = require 'efm/prettierd'

require'lspconfig'.efm.setup {
  init_options = { documentFormatting = true },
  filetypes = {'css', 'html', 'javascipt', 'json', 'markdown', 'sh', 'typescript', 'vue', 'yaml'},
  settings = {
    rootMarkers = { '.git', 'package.json' },
    languages = {
      javascript = { prettierd }
    }
  }
}

And here are my prettier configs:

// .config/prettierd/.prettierrc.json
{
  "trailingComma": "es5",
  "tabWidth": 2,
  "semi": false,
  "singleQuote": true
}

Now when I try to format using :lua vim.lsp.buf.formatting() changes are being applied, the problem is that none of my configs are taken into account (ie. all quotes are double and semicolons are added). Clearly there is another config overriding it somehow.

What am I overlooking?

EDIT: I can also confirm that when the .prettierrc.json is in the current directory, all works as expected.

@zeitchef thanks for the detailed information. I'll reopen this issue and try to reproduce it later.

[petertriho]

@zeitchef You probably need to restart the prettierd process

ps aux | grep prettierd
kill <process number>

Thanks for the tip @petertriho - that seemed to fix it. @fsouza Thanks so much for all your help and hard work on this great project!
