Re

An experimental editor written in Ruby.

The goal of Re is to remain tiny, pure-Ruby, and to leverage existing Ruby projects as much as possible. Where it makes sense I'll split code out into separate gems.

Suggestions/pull requests are welcome, but note that this is very much a quick and dirty work in progress, that I use for most of my editing, and that in many respects reflects very personal choices, so if you want to take things in a different direction I might not take your code - talk to me first if unsure (vidar@hokstad.com).

Ideally I'll turn this into mostly a set of gems providing generic editor-related functionality, and this project itself will be mostly tying other gems together.

Re uses DRb to implement a primitive client-server model (primitive as there are far more notifications than needed and far more redraws than needed as a consquence).

It tries to keep a dump of the state of open buffers in a JSON file for sessin recovery. Buffers remain open as long as the server process lives currently (not way of killing them).

Emacs style frame splits (alt+2/alt+3) are currently hardcoded to expect i3wm to open new view processes in new windows

Undo/Redo is buggy (it breaks if the modification deleted lines, at least). Needs test cases and a rework.

Note that lots of the code is horribly ugly and in need of refactoring.

Keyboard shortcuts

(likely outdated)

  • Ctrl-Q quits
  • Ctrl-S saves
  • Ctrl-P (previous), or the Up arrow key, moves the cursor up
  • Ctrl-N (next), or the Down arrow key, moves the cursor down
  • Ctrl-F (forward), or the Right arrow key, moves the cursor right
  • Ctrl-B (backward), or the Left arrow key, moves the cursor left
  • Ctrl-A or Home moves the cursor to the beginning of the line
  • Ctrl-E or End moves the cursor to the end of the line
  • Ctrl-H or Backspace deletes the previous character
  • Ctrl-D or Delete deletes the current character
  • Ctrl-U deletes the line text before the cursor
  • Ctrl-K deletes the line text after (and including) the cursor
  • Ctrl-- undoes the last change
  • Ctrl-R reloads from disk.

I (Vidar Hokstad) took Femto by Angelos Orfanakos, https://agorf.gr/ as a starting point, and modified it extensively.

There's not much left of Femto in here, so all blame for bugs here goes to Vidar.
