I call it religious, because there is a strong faith in the "one true way"

of doing things. By that I mean things like: "the tab size is always an

equivalent to 8 spaces/characters" or "each line ends with '\n' symbol and

someone should end this '\r\n' madness" or "text files are always utf-8

encoded". Most editors provide customizable options for these things, but

godit takes a different approach in that area and has no settings at all. So,

that concludes the ideology behind godit.

If you're interested in what godit feels like, it would be fair to say that it

is an emacsish lightweight text editor. The godit uses many of the emacs key

bindings and operates using a notion of "micromodes". It's easier to explain

what a micromode is by a simple example. Let's take the keyboard macros feature

from both emacs and godit. You can start recording a macro using `C-x (` key

combination and then when you're ready to start repeating it, you do the

following: `C-x e (e...)`. Not only `C-x e` ends the recording of a macro, it

executes the macro once and enters a micromode, where typing `e` again, will

repeat that action. But as soon as some other key was pressed you quit this

micromode and everything is back to normal again. The idea of micromode is used

in godit a lot.

--== Current development state==--

I'm still in process of designing some parts of it. Bits of functionality are

missing, but frankly I write godit in godit already and I use godit for

everything else on my system (EDITOR=godit). This README was written in godit

from scratch, I write commit messages in godit, I write code in godit, I write

configs and scripts in godit. The editor is definitely usable, but it is

certain that some corner cases are not covered. Just try it, perhaps you would

like it. Oh and I'm very picky about feature suggestions at the moment,

suggest, but don't expect too much.
