### CONFIGMELD

Compare two MAKEMAP configs using a visual file comparison tool

#### Description:

This script uses a visual file comparison tool such as " meld" , to display two sets of configuration parameters, highlighting the differences between them. Each config may be supplied directly, as is done when running MAKEMAP, or can be read from the History component of an NDF that was created by MAKEMAP.

#### Usage:

configmeld config1 config2 waveband defaults tool

#### Parameters:

##### CONFIG1 = LITERAL (Read)
The first configuration. This can be a normal config such as is supplied for the CONFIG parameter of MAKEMAP, or an NDF created by MAKEMAP.
##### CONFIG2 = LITERAL (Read)
The first configuration. This can be a normal config such as is supplied for the CONFIG parameter of MAKEMAP, or an NDF created by MAKEMAP. If a value is supplied for PARAM, then CONFIG2 defaults to null (!). []
##### WAVEBAND = LITERAL (Read)
This parameter is not used if either CONFIG1 or CONFIG2 is an NDF created by MAKEMAP. It should be one of " 450" or " 850" . It specifies which value should be displayed for configuration parameters that have separate values for 450 and 850 um. If either CONFIG1 or CONFIG2 is an NDF created by MAKEMAP, then the wavebands to use are determined from the headers in the NDFs.
##### DEFAULTS = _LOGICAL (Read)
If TRUE, then each supplied configuration (CONFIG1 and CONFIG2) is extended to include default values are any MAKEMAP parameters that it does not specify. These defaults are read from file " \$SMURF_DIR/smurf_makemap.def" . [TRUE]
##### PARAM = LITERAL (Read)
If supplied, then the value used for the specified parameter is displayed on standard output, and no visual comparison is displayed. Separate values are displayed for CONFIG1 and (if supplied) CONFIG2. [!]
##### TOOL = LITERAL (Read)
Gives the name of the file comparison tool to use. The named command should be available on the current PATH. It should take the names of two files to compare as command line arguments. If null (!) is supplied, the first available tool in the following list is used:
• meld: www.meldmerge.org

• opendiff: developer.apple.com

• diffmerge: www.sourcegear.com/diffmerge

• kdiff3: kdiff3.sourceforge.net

• tkdiff: sourceforge.net/projects/tkdiff

• diffuse: diffuse.sourceforge.net
