Pretty_hover is a light weight plugin that parses the hover message before opening the popup window. The output can be easily manipulated with. This will result in more readable hover message.
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.
How it looks
Using native vim.lsp.buf.hover() <img src="https://user-images.githubusercontent.com/59179935/230844931-49fdd776-2bf1-4017-8f08-fe4ac900c7c8.png">

Configuration
| Parameter | Description |
|---|---|
| line | If one of the supplied strings is located as the first word in line the whole line is surrounded by stylers.line. |
| listing | These words will be substituted with stylers.listing. |
| word | List of strings. If this word is detected at the beginning of a line the next word is surrounded by styles.word |
| header | List of strings. If this word is detected at the beginning of a line the word is substituted by styles.header |
| return statement | This words are substituted with Return (in bold) |
| references | If any word from this list is detected, the next word is surrounded by styles.references[1]. If this word is located in line section the next word is surrounded by stylers.references[2] (see Limitations) |
| hl | This is a table of highlighting groups. User can define new groups by specifying at least tow parameters. color and detect. Flag line is not mendatory, 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 hight of the window. If you don't want any limitation set to nil. |
| toggle | Flag detecting whether you want to have the hover just as a toggle window or make the popup focusable. |
NOTE: To really use this plugin you have to create a keymap that will call
require('pretty_hover').hover()function.
The plugin supports code blocks. By specifying @code{cpp} the text in 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.

-- Here you can setup your own highlight groups.
},
border = "rounded",
max_width = nil,
max_height = nil,
toggle = false,
}
Limitations
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.
