(Better name to be determined.)
This is a simple web application for building proficiency with Paredit (for Lisp, with default Emacs keyboard shortcuts) in a quiz format.
The app will present you with a series of questions (in random order). A question has two snippets of Lisp code, with the current cursor position indicated. The goal is to get from the first code snippet (transform this) to the second (to this) using a single Paredit.
By default, the Meta key (M-) corresponds to whatever key sets the altKey property for a keyboard event in your browser. The Ctrl key (C-) is triggered by the ctrlKey property. (You can change this behavior by updating options.keyBindings in index.coffee.)
The majority of these examples come from the Paredit Reference Card (pdf), with a couple of additions. Some questions have multiple possible solutions. In this case, any solution is valid.
For a given example, this app checks to see if you've used the command that corresponds to the example in the Reference Card. It does not actually emulate Emacs or Paredit—if a command is listed on the cheatsheet, and it's applicable to an example, it should work; other Paredit commands, or other Emacs commands will not work.
If you find an example that has a keyboard shortcut that doesn't work, please file an issue. (Or, if you have any further examples.)
Install dependencies:
npm install --production
bower install
Compile CoffeeScript to JavaScript, SCSS to CSS, and move everything into the build directory:
gulp build
(If you're actively working on the application, run gulp watch to rebuild whenever a source file changes.)
To start a server, run:
cd docs/ && http-server
The app can then be accessed at http://localhost:8080/.
