elm-format spawning vim.ui.select in neovim

[smoothprogrammer]

The elm-format when returning error will spawn vim.ui.select in neovim.

Expected Behavior

I'm expecting the LSP to not spawn vim.ui.select when elm-format returning error. Just ignore it.

Current Behavior

As you can see, when elm-format is returning error, it will spawn vim.ui.select with message Running elm-format failed. Check the file for syntax errors. which annoys me as I need to close them every time it shown which is often when you want save to get a useful feedback from elm compiler.

Possible Solution

Steps to Reproduce (for bugs)

1. Using native LSP in neovim https://github.com/neovim/nvim-lspconfig/blob/master/doc/configs.md#elmls
2. Just default configuration, nothing fancy
3. Write a invalid elm code
4. Save and LSP will spawn vim.ui.select due to elm-format returning error

Context

Your Environment

• Version used:
• Editor used: Neovim
• Environment name and version (e.g. node.js 5.4):

Found the code that print the error message.

elm-language-server/src/common/providers/documentFormatingProvider.ts

Lines 68 to 70 in dcdcdd0

	this.connection.window.showErrorMessage(
	"Running elm-format failed. Check the file for syntax errors.",
	);

would be really nice to configure this

Maybe showErrorMessage isn't what's wanted here? Either RemoteConsole.error or showMessage?

showMessage

Not sure what you mean by that, there are also this.connection.window.showInformationMessage and this.connection.window.showWarningMessage - but I can't find showMessage

It was pointed out that the TS library for LSP doesn't seem to surface this feature, so maybe showMessage isn't an option?

For the future: I was shown this workaround:

https://github.com/joakin/nvim/blob/bddf8f52ec92a5e23425b1a26f13d1c22a70106b/lua/plugins/lspconfig.lua#L183 which I can confirm works.
