Obtaining a Copy
The source code for the book is available at https://github.com/lfe/casting-spels. To get a copy of this code, simply run:
$ git clone https://github.com/lfe/casting-spels.git $ cd casting-spels
In this repository, the file
code/game.lfe contains all the code one enters in the REPL as following along in the book.
If you choose, you may load all of this code into the REPL as if you had typed it yourself:
$ make repl
Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:4:4] [async-threads:10] [kernel-poll:false] ..-~.~_~---.. ( \\ ) | A Lisp-2+ on the Erlang VM |`-.._/_\\_.-'; | Type (help) for usage info. | g (_ \ | | n | | | Docs: http://docs.lfe.io/ ( a / / | Source: http://github.com/rvirding/lfe \ l (_/ | \ r / | LFE v1.0 (abort with ^G) `-E___.-' >
> (run "game.lfe") game-data-loaded
And now you will be able to execute the commands that would be available at the end of the book.
As mentioned in the previous section, source code for an OTP version of the game has been made available in
code/spels. To start the REPL for this version, simply run
make otp-repl. Note that this code is very different from the code that is entered into the REPL throughout the course of the book, and some commands will not be present (or will have been changed).
For more details, please see the previous section.
