unable to initialize vale-ls with custom config location

[augustomelo]

I have vale installed on my machine and the config are on $XDG_CONFIG_HOME, since vale only looks for vale.ini under $HOME the usual way that run vale is for example vale sync --config='$XDG_CONFIG_HOME/vale/vale.ini'.

So I am currently trying to run vale-ls and say that the way to pass the config location is through initializationOptions.configPath and I am doing so (example bellow with neovim lspconfig)

  require('lspconfig').vale_ls.setup{
      capabilities = capabilities,
      filetypes = { 'gitcommit', 'markdown', 'text' },
      init_options = {
        configPath = vim.env.XDG_CONFIG_HOME .. '/vale/vale.ini'
      },
    }

I also tried to pass a path (vim.env.XDG_CONFIG_HOME .. '/vale/) on the configPath, but I keep getting the following error (log from nvim):

I believe the error is coming form a couple a functions that runs the vale command without taking the --config into consideration.

Edit: updated hypothesis

I also experience that issue. I found that as a workaround, setting VALE_CONFIG_PATH does work:

vim.env.VALE_CONFIG_PATH = "/path/vale.ini"

[chrisgrieser]

since vale 3.0.0, VALE_CONFIG_PATH does not work anymore, so that my workaround above also does not work anymore. errata-ai/vale#750

edit: VALE_CONFIG_PATH issue has been fixed, works again
