NAME

Image::DS9::Constants::V1 - predefined constants

VERSION

version v1.0.0

SYNOPSIS

# import all of the constants
use Image::DS9::Constants::V1 '-all';

# import a subset
use Image::DS9::Constants::V1 qw( const1 const2 );

# change the prefix and import all of the constants
use Image::DS9::Constants::V1 { prefix => 'X_' }, '-all';

# change the prefix and import a subset
# imports X_const1, X_const2
use Image::DS9::Constants::V1
   { prefix => 'X_' }, qw( const1 const2 );

# list the available constants
use Image::DS9::Constants::V1;
Image::DS9::Constants::V1::list;

DESCRIPTION

This module provides Perl constants for option strings used to communicate with DS9, making it easier to spot typos in code. For example,

use Image::DS9::Constants::V1
   { prefix => 'X_' }, qw( reset );

$ds9->regions( 'resett' );

will be caught at run time, while

$ds9->regions( X_resett );

will be caught at compile time.

Renaming constants

Image::DS9::Constants uses Exporter::Tiny, so the constant names can be modified when they are imported into the user's package. See that module's documentation for more information (See also the above "SYNOPSIS").

Groups of constants

Image::DS9 uses CXC::Exporter::Util to provide enumerating functions for groups of constants. To import an entire group (e.g. the DSS_ESO_SURVEYS group)

use Image::DS9::Constants -dss_eso_surveys;

To import the enumerating function for a group (e.g. the DSS_ESO_SURVEYS group):

use Image::DS9::Constants 'DSS_ESO_SURVEYS';

Listing Constants

To list the available constants, use the list function:

perl -MImage::DS9::Constants=list -e 'list'

This will print a listing of all of the constants.

CONSTANT GROUPS

The following groups are available. The group name is also the enumerating function for the constants in the group, e.g.

say $_ for ANGULAR_FORMATS;

results in

MISC

These are available, but deprecated, as they are common names for existing subroutines. It's best to import them with a prefix, e.g.

use Image::DS9::Constants::V1 { prefix => 'X_' }, -misc;

They have not been updated for DS9 V8.4.1, so some are no longer valid.
