According to `:help topleft` and `:help botright`, these commands creates a window with the full height of the Vim window when used with `vnew`, so we don't need to update the `height` variable when using these commands.
Before: Given two sets of hover documentation, a) longer text (more lines) and b) shorter text (fewer lines).. when moving from a) to b), the extra lines from a remain in the buffer.
After: With this change, the buffer is cleared before adding new hover text, thus removing the excess trailing lines from any previous hover text.
* refactor: use Lua API for user command
• remove "plugin" dir
• make toggle() local
* feat: add "bottom" as valid "position" opt
If "bottom" is given as "position" configuration value, open
the docs window at the bottom of the window. Adding the "height"
option complicates setting the window dimensions, e.g. if we are
opening a split on the sides but also change the height of the
window, it will resize "prev_win" as well. As a consequence, we
want to "reset" the width or height vals back to the current win
dimension depending on the position we choose.
Associated refactors:
• add default "height" value in default configuration
• rename user and default configuration tables for clarity
• programatically set default configuration table
* refactor: cleanup after change request
• use tbl_extend() to produce a new configuration table from
the default cfg and user cfg
• choose local variables over updating the default cfg when
updating height and width inside of toggle() based on the
chosen window position
• move the default cfg table inside of setup()
* Update README.md
Add GIF displaying functionality
* include demo.gif in the repo
