NAME

Poet::Environment -- Poet environment

SYNOPSIS

# In a script...
use Poet::Script qw($env);

# In a module...
use Poet qw($env);

# $env is automatically available in Mason components

# then...
my $root_dir       = $env->root_dir;
my $file           = $env->path("some/file.txt");
my $path_to_script = $env->bin_path("foo/bar.pl");
my $path_to_lib    = $env->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

$env->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

$env->conf_dir
   ==> returns /my/env/root/conf

$env->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

$env->conf_path("log4perl.conf");
   ==> returns /my/env/root/conf/log4perl.conf

$env->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.

$env->app_class('Cache')

will return MyApp::Cache if that module exists, and otherwise Poet::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 $env.

CONFIGURING ENVIRONMENT SUBDIRECTORIES

Any subdirectories other than conf_dir can be overriden in configuration. e.g.

# Override bin_dir
env.bin_dir: /some/other/bin/dir

With this configuration in place,

$env->bin_dir
   ==> returns /some/other/bin/dir

$env->bin_path("foo/bar.pl")
   ==> returns /some/other/bin/dir/foo/bar.pl
