Pretty_hover is a lightweight plugin that parses the hover message before opening the popup window. The output can be easily manipulated with. This will result in a more readable hover message.
An additional feature is number conversion
. If you are tired of constantly converting some numbers to hex, octal
or binary you can use this plugin to do it for you.
NOTE: The colors of the text depend on the color of your chosen colorscheme. These pictures are taken with colorscheme

Using native vim.lsp.buf.hover()
{
"Fildo7525/pretty_hover",
event = "LspAttach",
opts = {}
},
use {
"Fildo7525/pretty_hover",
config = function()
require("pretty_hover").setup({})
end
}
To open a hover window, run the following lua snippet (or bind it to a key)
require("pretty_hover").hover()
To close a hover window either move the cursor as with nvim's hover popup or run the following lua snippet (e.g. from a keymap)
require("pretty_hover").close()
NOTE: When focused on a hover window, you can also press q
to close the hover window

hl | This is a table of highlighting groups. You can define new groups by specifying at least two parameters. color and detect . Flag line is not mandatory, however by setting this flag you can ensure that the whole line is highlighted. When a detector from the table detect is found the detector is made uppercase, omits the beginning tag and gets highlighted. |
border | Sets the border of the hover window. (none |
max_width | Sets the maximum width of the window. If you don't want any limitation set to nil. |
max_height | Sets the maximum height of the window. If you don't want any limitation set to nil. |

function.
The plugin supports code blocks. By specifying @code{cpp}
the text in the popup window is highlighted with its filetype highlighter
until the @endcode
is hit. When the filetype is not specified in the flag @code
the filetype from the currently opened file is used.

Currently, neovim supports these markdown stylers: `, *, ```[language]. Unfortunately, you cannot do any of their combination. If the support is extended there will be more options to style the pop-up window. Newly this plugin started supporting highlighting see the Configuration for more information.
