PGAS and Games::Golf presentation
So you want to host a Perl golf contest? These games can be quite successful: for example the golf game organised by The Perl Review volume 0 issue 1 had more than 100 players, and a total of 500 entries were submitted.
So you need tools to run one of those fun and successful games.
PGAS (Perl Golf A S) is such a tool. Based on Games::Golf, a serie of modules to help writing tests for golf games, it should make the

Referee: Creating a test suite for use with Games::Golf
The test script used by the players makes use of the methods provided by the Games::Golf::TestSuite object.
A test suite is written in Perl. But since that code is in fact eval()ed somewhere deep in Games::Golf::TestSuite, you really have very little work to do.
A typical test suite will look like this:
# First test: the player script should at least compile
$test->compile;
$test->ioee( << INPUT, << OUTPUT, "", 0 );
This is the input
INPUT
We wait for this output
OUTPUTTesting a script
Two methods are used only for scripts:
- compile
- ioee
Testing a sub
Three methods are used only for subs:
- makesub
- sub
- ok
Other available methods
The following methods are used to test the code itself:
- not_string
- not_match
Placing restrictions on the code
You can force any test to break if some restrictions are not respected. More precisely, you can limit the running time of the script (by a timeout), and the size of stdout and stderr.
