Removed vim-exchange which, while an amazing functionality, is also
exactly replicated in mini.nvim (along with even more operators).
Uses slightly different mapping - not `cx<movement>` anymore but
`gx<movement>`. But this actually makes sense and fits in well with
my other g-prefixed operators (`gc` for comment and `ga` for align).
It is also the prefix for the other additional operators supplied
by mini.operators: `gs` for sorting text, `gm` for multiplying,
`gr` for replacing, `g=` for evaluating.
Since we already have the mini library installed in our setup, we don't
need to make use of external base16 plugins. It provides the same exact
functionality, and seems slim and bug-free. Nothing changes for the
user, but we have 1 plugin less to take care of (and it was
mis-behaving in new versions anyway).
Also set lualine to be reloaded on theme switch so it takes on the
colorscheme as well.
Enabled bracketed module of mini.nvim plugin, which enables many
(many!) more bracket jumping options. Some examples are moving
through the bufferlist, comments, files, jumplist, etc with [
and ]. Integrated into whichkey through pre-defined 'desc'
options for each mapping.
Moved plugins into individual component module files which are
automatically required by lazy.nvim. Should make everything a tiny bit
more modular, or at least prepare the way for true modularity if I ever
have the time on my hands to ensure everything works with missing
modules.
Moved core settings into their own directory (`core`), and created a
`personal` folder which contains functions/plugins I wrote that do not
necessarily have to be their own imported plugin yet.
Finally, extended the utility functions a little, so we can detect if a
plugin exists and change e.g. key maps based on that (once again,
extending modularity a little more). Some simple attempts have been made
at that in the `mappings.lua` file, though it is nowhere near extensive
yet - most keymaps are still set regardless of plugin availability.
However, with this slimmer base to work off of, I feel more confident in
changing future things about this setup a little more ad-hoc without
having as many ripple repercussions as before.
