-# diagnostic-nvim
+# diagnostic-nvim (DEPRECATED)
 
-The built- in Nvim language server support is amazing, but the diagnostics setting
-that it shipped with it by default may not be as great as other LSP plugins.
-Fortunately, it's very customizable with changing the default callback function
-with lua. This plugin tries to focus on wrapping the diagnostics setting up to
-make it a more user friendly without adding too much to it.
+After the creation of `vim.lsp.diagnostic` (See: https://github.com/neovim/neovim/pull/12655) 
+`nvim-lua/diagnostic.nvim` is deprecated. To find out how to migrate, checkout the [migration guide](https://github.com/nvim-lua/diagnostic-nvim/issues/73).
 
-## Features
-
-- Options to disable/enable virtual text.
-- Pipe diagnostic information into location list.
-- Jump to next/previous diagnostic under your cursor.
-- Automatically open pop up window that shows line diagnostic while jumping.
-- Show error sign in columns.
-- Show error underline in symbols.
-- Delay diagnostic when you're in insert mode.
-
-## Demo
-![Demo](https://user-images.githubusercontent.com/35623968/75627012-6824f380-5c07-11ea-8f25-59ce1751e902.gif)
-
-## Prerequisites
-
-- Neovim nightly
-- You should set up your language server of choice with the help of [nvim-lsp](https://github.com/neovim/nvim-lsp)
-
-## Install
-
-- Install with any plugin manager by using the path on GitHub.
-
-```vim
-Plug 'nvim-lua/diagnostic-nvim'
-```
-
-## Setup
-
-- Diagnostic-nvim requires several autocommands set up to work properly. You should
-  set it up using the `on_attach` function like this.
-
-```vim
-lua require'nvim_lsp'.pyls.setup{on_attach=require'diagnostic'.on_attach}
-```
-
-- Change `pyls` to whichever language server you're using.
-
-## Commands
-
-- Use `PrevDiagnostic` and `NextDiagnostic` to jump to the previous and next diagnostic
-  under your cursor.
-- `PrevDiagnosticCycle` and `NextDiagnosticCycle` not only jump to the previous and next diagnostic but also
-cycle through the diagnostic if you're at the first or last diagnostic.
-- `OpenDiagnostic` will open a location list and jump back to previous window.
-
-## Options
-
-### Enable/Disable virtual text
-
-- Diagnostic-nvim has an option that lets you toggle the virtual text. Virtual text
-  is disabled by default. You can enable it by
-
-```vim
-let g:diagnostic_enable_virtual_text = 1
-```
-
-### Change virtual text prefix
-
-- Diagnostic-nvim provides an option to change the virtual text prefix, the
-  default prefix is '■', but if you have nerd font or other power line font
-  support, you can make it a little more fancy by adding something like:
-
-```vim
-let g:diagnostic_virtual_text_prefix = ' '
-```
-
-### Trimming virtual text
-
-- Sometimes you can be working with language which has long virtual text,
-  Diagnostic-nvim provides an option to trim the virtual text to fit your usage by
-
-```vim
-let g:diagnostic_trimmed_virtual_text = '20'
-```
-
-- If the virtual text exceeds the value that you set, `...` will be displayed in the end.
-- Note that setting this option to `0` means that it will only show the prefix.
-- By default, this value is set to `v:null`, which means it's not trimmed at all.
-
-### Spaces before virtual text
-- By default, there will be only a space before virtual text. You can add more spaces by
-
-```vim
-let g:space_before_virtual_text = 5
-```
-
-### Enable/Disable Sign
-
-- By default, the build-in Nvim LSP will show a sign on every line that you have
-  a diagnostic message on. You can turn this off by
-
-```vim
-let g:diagnostic_show_sign = 0
-```
-
-- The default priority of the diagnostic sign is 20. You can customize it by
-
-```vim
-let g:diagnostic_sign_priority = 20
-```
-
-- Make sure to use the latest branch of Neovim which has sign support.
-
-- If you want to change the symbols of sign, use `sign_define` to change it
-
-```vim
-call sign_define("LspDiagnosticsErrorSign", {"text" : "E", "texthl" : "LspDiagnosticsError"})
-call sign_define("LspDiagnosticsWarningSign", {"text" : "W", "texthl" : "LspDiagnosticsWarning"})
-call sign_define("LspDiagnosticsInformationSign", {"text" : "I", "texthl" : "LspDiagnosticsInformation"})
-call sign_define("LspDiagnosticsHintSign", {"text" : "H", "texthl" : "LspDiagnosticsHint"})
-```
-
-### Enable/Disable Underline
-
-- By default, the build-in Nvim LSP will show a underline on every symbol that
-  you have a diagnostic message on. You can turn this off by
-
-```vim
-let g:diagnostic_enable_underline = 0
-```
-
-### Enable/Disable auto popup window
-
-- When you jump to next or previous diagnostic, line diagnostic message will popup
-  in a popup window, you can disable it by
-
-```vim
-let g:diagnostic_auto_popup_while_jump = 0
-```
-
-### Enable/Disable insert delay
-
-- Neovim's built-in LSP support will keep sending diagnostic messages when you're
-  in insert mode. Sometimes this can be kind of distraction especially when you have
-  virtual text enabled. If you don't want to show diagnostics while in insert mode,
-  set the following
-
-```vim
-let g:diagnostic_insert_delay = 1
-```
-
-## WARNING
-
-- This plugin is in the early stages and might have unexpected issues.
-- Feel free to post issues on any unexpected behavior or open a feature request!
+You should uninstall diagnostic-nvim if you are on latest master.
