Diagnostics in nvim

Neovim’s internal diagnostic tool vim.diagnostic is a framework for diagnostic producers to report diagnostics link.

Since Neovim v0.11+, the way to configure language servers has moved from the legacy require('lspconfig') to vim.lsp.config() & vim.lsp.enable().

This removes the need to install nvim-lspconfig package and in my opinion simplifies the process to get started with language servers.

Tiny inline diagnostic

While the Neovim does support inline citaton the difference is documented here

I installed the plugin tiny-inline-diagnositic due to ability to keep the diagnostic message compact and show the issues when I am on that line.

The lack of clutter leads to better clarity when writing code and triaging of issues.

To use this diagnostic tool you first need to switch off the virtual_text in the native inline diagnostics

vim.diagnostic.config({
	underline = true,     -- set underline for offending line to true
	virtual_text = false, -- set virtual_text as false
})

Then set the configs necessary for the tiny-inline-diagnositic plugin.

require('tiny-inline-diagnostic').setup({
	preset = 'ghost',                              -- icons set to ghosts
	options = {
		add_messages = { display_count = true },   -- additional messages count of errors encountered on line
		show_source = { enabled = true },          -- show the source of the error
		multilines = { enabled = true },           -- additional messages to bleed over to next line
	},
	blend = { factor = 0.2 },                      -- visbility of diagnostic
})

Once created the plugin will show as below
