Application to support working through sequential programming problems, with crowd-sourced code reviews.
This an experiment, and the code reflects that. Many features have been thrown in, only to be deprecated shortly thereafter, and there's scar tissue throughout the system.
Features may be here today, gone tomorrow.
Things do seem to have settled a bit in the past couple of months, so there's a chance that we'll reach some sort of 1.0 in early 2014.
The messaging right now is a disaster. The site is confusing, the process is opaque, and it's hard to figure out where you need to look to figure stuff out.
What we think we know
This is a process with two parts:
- practice (writing code, iterating)
- nitpicking (looking at code, providing insights and asking questions)
It's not about getting code perfect or right, but using the pieces of code to talk about the little details of what makes code simple, readable, and/or expressive.
The warmup exercises are collected from all over the web.
The common data for assignments are in
This includes some metadata that gets sewn into a README.
Not all assignments will be appropriate for all languages.
The actual assignment consists of a test suite, where all test are pending except the first one.
The languages paths are configured in
The list of assignments is just a really big array of assignment slugs in the order that they will be assigned.
Different languages/trails do not need to have the same assignments or the same order.
- Install postgresql with:
brew install postgresqlor
apt-get install postgresql-9.2
.ruby-versionif you use a Ruby version manager such as RVM, rbenv or chruby
- Install gems with:
gem install mailcatcher
- Get a client id/secret from GitHub at https://github.com/settings/applications/new.
- Presuming you have Postgres installed (if not:
brew install postgres):
- create db user with:
- create database with:
createdb -O exercism exercism_development.
- Run the database migrations with
- Run the database seed with
rake db:seed. If you want LOTS of data:
rake db:seedor some other big number.
.envto fill in the correct values, including the GitHub client id/secret procured earlier.
- Start the server with
- Login at http://localhost:4567.
- You can view the emails sent in MailCatcher in your browser at localhost:1080.
- Work through 'Frontend development setup' below and run lineman for correct styling at http://localhost:4567
Frontend development setup
- Install node and npm
- osx: brew install node
- others see: https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
- Install lineman via
sudo npm install -g lineman
cd frontendand start lineman with
- note lineman watches for file changes and compiles them automatically, it is not required to be running for the server to run
If you want to send emails, you will need to fill out the relevant environment variables in
.env and uncomment the lines so that the variables get exported.
There's a script in
bin/console that will load pry with the exercism environment loaded.
- Prepare the test environment with
RACK_ENV=test rake db:migrate.
- Make sure that
- Run the test suite with
To run a single test suite, you can do so with:
If it complains about dependencies, then either we forgot to require the correct dependencies (a distinct possibility), or we are dependening on a particular tag of a gem installed directly from github (this happens on occasion).
If there's a git dependency, you can do this:
bundle exec ruby path/to/the_test.rb
For the require, you'll need to figure out what the missing dependency is. Feel free to open an issue on github. It's likely that someone familiar with the codebase will be able to identify the problem immediately.
To enable code coverage run:
COVERAGE=1 rake test
