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 commit has 2 changes:
- preload.lua is now init.lua in the prelude folder. the reason
for the name change of preload to prelude is to make update/
overwrite not hell
- the guide command has been added which is a simple step through
getting started type of thing for new users
"xdg" is basically a linux specific thing and it acted linux specific also.
so replace that with a more portable and general "userDir" table
config is for the user's config directory and also defaults to xdg vars on linux.
data is a directory to store data, mostly for scripts.
on other oses beside linux, it is just the config directory for now
