Diagnostic Icons

[kaykhancheckpoint]

Hi, how do i get the diagnostic icons in the gutter?

Plug 'kyazdani42/nvim-web-devicons'
Plug 'folke/trouble.nvim'

Until my lsp.config PR lands, you can use the code below:

local signs = { Error = " ", Warning = " ", Hint = " ", Information = " " }
for type, icon in pairs(signs) do
  local hl = "LspDiagnosticsSign" .. type
  vim.fn.sign_define(hl, { text = icon, texthl = hl, numhl = "" })
end

[kaykhancheckpoint]

Added this after my plugins

lua << EOF
local signs = { Error = " ", Warning = " ", Hint = " ", Information = " " }
for type, icon in pairs(signs) do
  local hl = "LspDiagnosticsSign" .. type
  vim.fn.sign_define(hl, { text = icon, texthl = hl, numhl = "" })
end
EOF

It did not work

@folke Can you tihnk of anything else i might be missing?

udpate:

I found i can see the icons for one file but not the other, its quite strange.

[folke]

@kaykhancheckpoint are you using LSP saga by any chance? If so don't put in the code I posted and configure the symbols through saga

At least for me, I had to add the snippet from #52 (comment) to my config, otherwise errors in the gutter would show with "E":

:echo sign_getdefined("LspDiagnosticsSignError")
[{'name': 'LspDiagnosticsSignError', 'numhl': '', 'texthl': 'LspDiagnosticsSignError', 'linehl': '', 'text': 'E '}]

Is trouble.nvim supposed to set the signs automatically?

In my case this not works

Same for me. I'm wondering the same myself

[mrshmllow]

I cant seem to change it no matter what i do

FWIW, I was having the same issue. Changing the sign from LspDiagnosticsSign .. type to DiagnosticSign .. type resolved the issue for me.

local signs = {
    Error = " ",
    Warning = " ",
    Hint = " ",
    Information = " "
}

for type, icon in pairs(signs) do
    local hl = "DiagnosticSign" .. type
    vim.fn.sign_define(hl, {text = icon, texthl = hl, numhl = hl})
end

@coldis yep, exactly. For 0.6 there were a bunch of changes to diagnostics

[Johan-Palacios]

This works for me
vim.cmd [[ sign define DiagnosticSignError text= linehl= texthl=DiagnosticSignError numhl= sign define DiagnosticSignWarn text= linehl= texthl=DiagnosticSignWarn numhl= sign define DiagnosticSignInfo text= linehl= texthl=DiagnosticSignInfo numhl= sign define DiagnosticSignHint text=💡 linehl= texthl=DiagnosticSignHint numhl= ]]

If you use the bleeding edge dev build of nvim,
local hl = "DiagnosticSign" .. type works
For 0.51 build local hl = "LspDiagnosticsSign" .. type works

FWIW, I was having the same issue. Changing the sign from LspDiagnosticsSign .. type to DiagnosticSign .. type resolved the issue for me.

Thanks, that worked for me. I want to stress for people who try this:
It's Diagnostic not Diagnostics, it's not just the Lsp prefix that got removed

Warning and Information has been renamed too.
Here's the full difference between neovim 0.5.1 and 0.6.0:

 local signs = {
   Error = "E",
-  Warning = "W",
+  Warn = "W",
   Hint = "H",
-  Information = "I"
+  Info = "I",
 }
+
 for type, icon in pairs(signs) do
-  local hl = "LspDiagnosticsSign" .. type
+  local hl = "DiagnosticSign" .. type
   vim.fn.sign_define(hl, { text = icon, texthl = hl, numhl = "" })
 end
