- Create a
Phakefilein the current directory or a parent directory - Invoke
./phake task:nameto invoke task or./phake -Tto list defined tasks
Define tasks like this:
task('dependency1', function() {
echo "i will run first!\n";
});
task('dependency2', function() {
echo "i will run second!\n";
});
task('task_name', 'dependency1', 'dependency2', function() {
echo "i will run last!\n";
});
This task would be invoked from the command line by ./phake task_name
Task bodies are optional if you want to create some sort of "super-task" that just invokes a bunch of others:
task('foo', 'dep1', 'dep2');
And multiple bodies can be added to tasks, all of which will be executed when the task is invoked:
task('foo', function() { echo "task work item 1\n"; });
task('foo', function() { echo "task work item 2\n"; });
Like Rake, we can group tasks:
group('db', function() {
task('init', function() {
echo "i'm initialising the database\n";
});
});
This would be invoked by ./phake db:init
Call desc() immediately before defining a task to set its description:
desc("Initialises the database");
task('db_init', function() { echo "oh hai it's a database\n"; });
Output from ./phake -T:
db_init Initialises the database
Sometimes you may want to specify that some code should run before or after a task (distinct from dependencies), a bit like Capistrano. Phake supports this:
before('foo', function() { ... });
after('baz:bar', function() { ... });
Phake allows arguments to specified on the command line:
# Execute task `quux` with the given args
./phake quux name=Jason city=Glasgow
This format must be matched exactly; do not put spaces between = and the argument name/value. If you need to put spaces in the argument value, place the entire assignment in quotes.
Arguments are made available to tasks by the application object's ArrayAccess implementation:
task('task_with_args', function($app) {
$name = $app['name'];
$city = $app['city'];
// do some stuff...
});
To abort execution of a task sequence, simply throw an exception.
desc('Demonstrate failure');
task('fail', function() {
throw new Exception;
});
Running phake fail will yield:
- jason@disco phake % ./bin/phake fail
(in /Users/jason/dev/projects/phake)
aborted!
Exception
(See full trace by running task with --trace)
This is what a complete Phakefile might look like. It also highlights some of the more complex name resolution issues arising when dealing with groups.
<?php
desc('Load the application environment');
task('environment', function() {
echo "I am the outer environment. I should run first.\n";
});
desc('Initialises the database connection');
task('database', function() {
echo "I am initialising the database...\n";
});
group('test', function() {
// 'environment' dependency for this task is resolved locally to
// task in same group. There is no 'database' task defined in this
// group so it drops back to a search of the root group.
desc('Run the unit tests');
task('units', 'environment', ':environment', 'database', function() {
echo "Running unit tests...\n";
});
// another level of nesting; application object is passed to all
// executing tasks
group('all', function() {
desc('Run absolutely every test everywhere!');
task('run', 'test:units', function($application) {
echo "All tests complete! ($application)\n";
});
});
});
// duplicate group definitions are merged
group('test', function() {
// duplicate task definitions are merged
// (although the first description takes precedence when running with -T)
desc("You won't see this description");
task('units', function() {
echo "Running a second batch of unit tests...\n";
});
// use ':environment' to refer to task in root group
// we currently have no cyclic dependency checking, you have been warned.
task('environment', ':environment', function() {
echo "I am the inner environment. I should run second.\n";
});
});
task('default', 'test:all:run');
?>
Here's the output from ./phake (implied task to run is default):
jason@ratchet phake [master*] $ ./phake
(in /Users/jason/dev/projects/phake)
I am the outer environment. I should run first.
I am the inner environment. I should run second.
I am initialising the database...
Running unit tests...
Running a second batch of unit tests...
All tests complete! (<phake\Application>)
And the corresponding output from phake -T:
jason@ratchet phake [master*] $ ./phake -T
(in /Users/jason/dev/projects/phake)
database Initialises the database connection
environment Load the application environment
test:all:run Run absolutely every test everywhere!
test:units Run the unit tests
Bashkim Isai has created phake-autocomplete, a bash-completion script for phake task names.
