NAME
Poet::Environment -- Poet environment
SYNOPSIS
# In a script...
use Poet::Script qw($poet);
# In a module...
use Poet qw($poet);
# $poet is automatically available in Mason components
# then...
my $root_dir = $poet->root_dir;
my $file = $poet->path("some/file.txt");
my $path_to_script = $poet->bin_path("foo/bar.pl");
my $path_to_lib = $poet->lib_path("Foo/Bar.pm");
DESCRIPTION
The Poet::Environment object contains information about the current environment and its directory paths.
PATH METHODS
- root_dir
-
Returns the root directory of the environment, i.e. where .poet_root is located.
- path (subpath)
-
Returns the root directory with a relative subpath added. e.g. if the Poet environment root is
/my/env/root
, then$poet->path("somefile.txt"); ==> returns /my/env/root/somefile.txt
- bin_dir
- comps_dir
- conf_dir
- data_dir
- db_dir
- lib_dir
- logs_dir
- static_dir
-
Returns the specified subdirectory, which by default will be just below the root dirctory. e.g. if the Poet environment root is
/my/env/root
, then$poet->conf_dir ==> returns /my/env/root/conf $poet->lib_dir ==> returns /my/env/root/lib
- bin_path (subpath)
- comps_path (subpath)
- conf_path (subpath)
- data_path (subpath)
- db_path (subpath)
- lib_path (subpath)
- logs_path (subpath)
- static_path (subpath)
-
Returns the specified subdirectory with a relative subpath added. e.g. if the Poet environment root is
/my/env/root
, then$poet->conf_path("log4perl.conf"); ==> returns /my/env/root/conf/log4perl.conf $poet->lib_path("Data/Type.pm"); ==> returns /my/env/root/lib/Data/Type.pm
OTHER METHODS
- app_class
-
Returns the full class name to use for the specified class, depending on whether there is a subclass in the environment. e.g.
$poet->app_class('Cache')
will return
MyApp::Cache
if that module exists, and otherwisePoet::Cache
. This is used internally by Poet to implement auto subclassing. - app_name
-
Returns the app name, e.g. 'MyApp', found in .poet_root.
- conf
-
Returns the Poet::Conf object associated with the environment. Usually you'd access this by importing
$conf
. - current_env
-
A class method that returns the current (singleton) environment for the process. Usually you'd access this by importing
$poet
.
OBTAINING $poet SINGLETON
In a script:
use Poet::Script qw($poet);
In a module:
use Poet qw($poet);
$poet
is automatically available in components.
You can also get it via
my $poet = Poet::Environment->current_env;
CONFIGURING ENVIRONMENT SUBDIRECTORIES
Any subdirectories other than conf_dir can be overridden in configuration. e.g.
# Override bin_dir
env.bin_dir: /some/other/bin/dir
With this configuration in place,
$poet->bin_dir
==> returns /some/other/bin/dir
$poet->bin_path("foo/bar.pl")
==> returns /some/other/bin/dir/foo/bar.pl
