Lua Carousel

screenshot

A lightweight environment for writing small, throwaway Lua and LÖVE programs. Tested on Windows, Mac, Linux, iOS and Android. The environment itself can be modified as it runs. In early release; please report issues, particularly with usability or accessibility.

This repo is an example of a Freewheeling App, designed above all to be easy to run, easy to modify and easy to share.

Getting started

Install LÖVE. It's just a 5MB download, open-source and extremely well-behaved.

Run the app using LÖVE.

Hacking

To modify it live without restarting the app each time, download the driver app. Here's an example session using a fork of this repo:

making changes without restarting the app

(Only on non-mobile platforms for now.)

Some reference documentation on how to create your own apps.

If the app being modified by the driver lives in a .love file, your changes will go into the save directory. If it lives in a directory (like this repo), your changes will go straight into the same directory.

Keyboard shortcuts

Within the editor widget:

  • ctrl+f to find patterns within a file
  • ctrl+c to copy, ctrl+x to cut, ctrl+v to paste
  • ctrl+z to undo, ctrl+y to redo
  • ctrl+= to zoom in, ctrl+- to zoom out, ctrl+0 to reset zoom
  • alt+right/alt+left to jump to the next/previous word, respectively
  • mouse drag or shift + movement to select text, ctrl+a to select all

Exclusively tested so far with a US keyboard layout. If you use a different layout, please let me know if things worked, or if you found anything amiss: http://akkartik.name/contact

Known issues

  • No support yet for Unicode graphemes spanning multiple codepoints.

  • No support yet for right-to-left languages.

  • Undo/redo may be sluggish in editor windows containing large files. Large files may grow sluggish in other ways.

  • If you kill the process, say by force-quitting because things things get sluggish, you can lose data.

  • Can't scroll while selecting text with mouse.

  • Some colors can't be customized yet.
