This module provides methods to set and retreive variaous names associated with the program and the program version number.
These methods provide the accessor and set methods for various names associated with an application.
get_current
$ctx = UR::Context::Process->get_current();
This is the context which represents the current process.
Also available as UR::Context->get_process();
has_changes()
$bool = UR::Context::Process->has_changes();
Returns true if the current process has changes which might be committed back to the underlying context.
_create_for_current_process
$ctx = UR::Context::Process->_create_for_current_process(@PARAMS)
This is only used internally by UR. It materializes a new object to represent a real process somewhere.
TODO: Remove the exception from create(), and allow other processes to be created explicitly w/ the appropriate characteristics.
base_name
$name = UR::Context::Process->base_name;
This is basename($0, '.pl')).
basename($0, '.pl'))
prog_name
$name = UR::Context::Process->prog_name; UR::Context::Process->prog_name($name);
This method is used to access and set the name of the program name.
This name is used in the output of the version and usage subroutines (see "version" and "usage"). If given an argument, this method sets the program name and returns the new name or undef if unsuccessful.
version
usage
undef
It defaults to basename if unspecified.
basename
pkg_name
$name = UR::Context::Process->pkg_name; UR::Context::Process->pkg_name($name);
This method is used to access and set the GNU-standard package name for the package to which this program belongs. This is does NOT refer-to a Perl package. It allows a set of spefic programs to be grouped together under a common name, which is used in standard message output, and is used in the output of the version subroutine (see "version" output.
If given an argument, this method sets the package name and returns the the new name or undef if unsuccessful. Without an argument, the current package name is returned.
It defaults to prog_name when unspecified, which in turn defaults to base_name, which in turn defaults to basename($0).
basename($0)
title
$name = UR::Context::Process->title; UR::Context::Process->title($name);
This gets and sets the "friendly name" for an application. It is often mixed-case, with spaces, and is used in autogenerated documentation, and sometimes as a header in generic GUI components. Without an argument, it returns the current title. If an argument is specified, this method sets the application title and returns the new title or undef if unsuccessful.
It defaults to pkg_name when otherwise unspecified, which in turn defaults to prog_name when unspecified, which in turn defaults to base_name when unspecified, which defaults to basename($0) when unspecified.
$version = UR::Context::Process->version; UR::Context::Process->version($version);
This method is used to access and set the package version. This version is used in the output of the print_version method (see "print_version" in App::Getopt). If given an argument, this method sets the package version and returns the version or undef if unsuccessful. Without an argument, the current package version is returned.
print_version
This message defaults to $main::VERSION if not set. Note that $main::VERSION may be undef.
$main::VERSION
author
$author = UR::Context::Process->author; UR::Context::Process->author($author);
This method is used to access and set the package author. If given an argument, this method sets the package author and returns the author or undef if unsuccessful. Without an argument, the current author is returned.
author_email
$author_email = UR::Context::Process->author_email; UR::Context::Process->author_email($author_email);
This method is used to access and set the package author's email address. This information is used in the output of the usage method (see "usage" in App::Getopt). If given an argument, this method sets the package author's email address and returns email address or undef if unsuccessful. Without an argument, the current email address is returned.
support_email
$support_email = UR::Context::Process->support_email; UR::Context::Process->support_email($support_email);
This method is used to access and set the email address to which the user should go for support. This information is used in the output of the usage method (see "usage" in App::Getopt). If given an argument, this method sets the support email address and returns that email address or undef if unsuccessful. Without an argument, the current email address is returned.
real_user_name
$login = UR::Context::Process->real_user_name;
This method is used to get the login name of the effective user id of the running script.
effective_user_name
$login = UR::Context::Process->effective_user_name;
original_program_path
$path = UR::Context::Process->original_program_path;
This method is used to (try to) get the original program path of the running script. This will not change even if the current working directory is changed. (In truth it will find the path at the time UR::Context::Process was used. So, a chdir before that happens will cause incorrect results; in that case, undef will be returned.
