basically, i have a `c` alias which is `git commit`,
this would resolve to `git commit` literally to try
and complete `commit`, which wouldnt match.
this fixes that, and instead itll suggest commands
that start with `c`. if there is a space after and
completion is requested, itll use the alias properly
prelude is no longer. it is now nature.
organized the single file prelude into multiple
source files and renamed it to nature. this is coming
after thought that it can turn into a general hilbish
lua core, with user facing modules as well.
this introduces the `nature.dirs` module, to interact
and get recently changed to directories and last/old
cwd.
this also makes the completion functions `bins`
and `files` also return the prefix to pass
to the completion handler.
this is an overhaul to the completion system,
which gets the completion handler from lua
instead of being made to only have lua provided
*command* completions.
it does not have any performance deficit, even
though it calls in to golua for completions.
with the change of blocking changes to the
hilbish table, i took an opportunity
to make the highlighter and hinter callbacks
set in a more natural way. instead of being
a function which takes a callback, you set
the function itself.
changed the way file completions are handed
completely, which fixes#130 and makes the
full name appear in the completion menu instead
of it being cut off
if an alias is something which isn't valid syntax,
specifically if hilbish cant split up the input
properly to execute, it will report the error to
the user. the previous behaviour was a panic since
on error the args slice will be of length 0
this is basically an edge case and fixes a bug
which shouldnt happen normally
