nunb / erlang_koans-1 Goto Github PK

Inspired by the ruby koans.

The koans are intended to only rely on erlang and the erlang scripting environment escript. The testing framework is eunit.

To run the koans use the koans executable with the command escript koans. This will compile your code and provide the next failing test in the suite to pass.

To run the development tests with substituted answers from answers.config use the command escript koans test.

To show a hint for the current koan, use escript koans hint.

Homebrew can be used to install Erlang, but it has an out-of-date version (R15B). To get the most updated version (R16B), you can tap into the homebrew/homebrew-versions repo, and get the erlang-r16 formula from there. To do this, run brew tap homebrew/versions followed by brew install erlang-r16.

Unfortunately, aptitude has an old version of erlang which is less than ideal.

First, install all necessary dependencies apt-get -y install build-essential m4 libncurses5-dev libssh-dev unixodbc-dev libgmp3-dev libwxgtk2.8-dev libglu1-mesa-dev fop xsltproc default-jdk

Next, move to some place to install erlang and pull the .tar.gz wget http://www.erlang.org/download/otp_src_R16B.tar.gz

Followed by tar -xvzf otp_src_R16B.tar.gz and chmod -R 777 otp_src_R16B

Move to the install directory cd otp_src_R16B

Then run ./configure, make, make install which will produce a bin/ directory. Place this bin/ directory on your path. Specifically, the koans require the erl, erlc, and escript binaries.
