Pablo's own Editor

A small ncurses based console text editor with vi keybindings written in Python

This is a small editor I did with the intention of using it, it lacks vi POSIX compatibility and lacks a lot of commands, but it is easier to extend than others (at least for me)

Featuring:

• Somehow vi-alike keybindings
• Full UTF-8 support
• Syntax highlighting using pygments for a whole lot of languages
• A cool game (2048)
• Hellfire!!

Requirements

Requires Python 3.5, setuptools and pygments. To install on Debian Wheezy:

    apt-get install python3-pygments python3-setuptools

You will need also a terminal emulator and locale that support UTF-8, and a font that can display Unicode graphic characters. As a reference, i use 'Bitstream Vera Sans Mono' in an xterm (xterm -fs 12 -fa 'Bitstream Vera Sans Mono')

If you have a terminal that supports 256 colors, they will be used. But only if you set the $TERM environment variable correctly. I do export TERM=xterm-256color in xterm and TERM=screen-256color in tmux to get 256 colors.

Installation

Install system-wide, with executable in /usr/local/bin/hellfire:

    sudo python3 ./setup.py install

Supported vi commands

• Motion commands:
• k, j, h, l, +, -, cursor keys

Insert mode:

Ex (:) mode:

Unsupported vi features

There is no horizontal scroll...

You can not prefix a command with a repetition number (i.e. 10j)

Delete to end of line or to end of world (d$, dw) is not implemented

There is no undo (yet)
