# Toy interpreter for Brainf@@k https://en.wikipedia.org/wiki/Brainfuck ![screenshot](assets/bf.gif) Example program for trying out [driver.love](https://git.sr.ht/~akkartik/driver.love), a programming environment for modifying programs live, without restarting them. [Some reference documentation on how to create your own apps.](reference.md) This repo is an example of a [Freewheeling App](http://akkartik.name/freewheeling), designed above all to be easy to run, easy to modify and easy to share. ## Getting started Install [LÖVE](https://love2d.org). It's just a 5MB download, open-source and extremely well-behaved. [Run the app using LÖVE.](https://love2d.org/wiki/Getting_Started#Running_Games) ## Hacking To modify it live without restarting the app each time, download [the driver app](https://git.sr.ht/~akkartik/driver.love). ![screenshot of driver app showing overview of this repo](assets/bf-codemap.gif) If the app being modified by the driver lives in a .love file, your changes will go into the [save directory](https://love2d.org/wiki/love.filesystem.getSaveDirectory). If it lives in a directory (like this repo), your changes will go straight into the same directory. ## Keyboard shortcuts Press `f4` to evaluate a program. Within each editor panel: * `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 ## Mirrors and Forks This repo is a fork of [lines.love](http://akkartik.name/lines.html), an editor for plain text where you can also seamlessly insert line drawings. Its immediate upstream is [the template repo for freewheeling apps](https://git.sr.ht/~akkartik/template-live-editor). Updates to it can be downloaded from the following mirrors: * https://git.sr.ht/~akkartik/bf.love * https://tildegit.org/akkartik/bf.love * https://git.merveilles.town/akkartik/bf.love * https://nest.pijul.com/akkartik/bf.love (using the Pijul version control system) Further forks are encouraged. If you show me your fork, I'll link to it here. ## Feedback [Most appreciated.](http://akkartik.name/contact)
