# it

*UNIX ed for a new age...*

Just kidding, no need to use this over ed.
This is just my take on a line editor, heavily inspired by ed.

For disambiguation it's suggested that this project be referred to as "ited", pronounced however one likes (suggested: "iht-ehd").

## Included commands

### !

Passes arguments to Python `subprocess.run`.

### buffer

This is where code relating to the Buffer class is kept but calling this from within the editor will allow you to view the current buffer's attributes.

### dot

Change the current position within the buffer.
### exit

Will exit via sys.exit rather than telling main.py to break out of the main loop. Functionally identical to `Q`.

### f

Displays or changes the filename associated with the current buffer.

### it

Launches a new instance of `it`.

It should be noted that quitting a nested instance of `it` through the usual means (`exit`, `q`, or `Q`) will exit all nested instances of `it` as well.
To return to a higher instance of `it`, send an EOF character via your terminal. In xterm this is CTRL+d.

### load\_module

Manually loads a module, whether or not it was already loaded.

### parse\_command

Used by `it`'s main Python module but calling this from within the editor will allow you to test the command argument splitting.

### Q

Quits.

### q

Quits, unless your current buffer is unsaved.

### saved

With no arguments given, flips the buffer's "saved" boolean attribute.
Otherwise, sets the buffer's "saved" attribute to the first argument or errors if multiple arguments given.

### version

Prints the versions of given modules.
If no modules are specified, prints the version of module "it".

## Making new commands

Making new commands is very easy.
Read `buffer.py` and `it.py` (<100 LOC total).
