Variable

SYNOPSIS

NAME value

DESCRIPTION

The directive defines a variable that will be available either globally (if defined in interchange.cfg) or within a catalog (if defined in catalog.cfg).

Variable names are case sensitive and can only contain word characters (that is, a-z, A-Z, 0-9 and _).

Once the variable is defined, it can be accessed using the following syntax:

__NAME__ - to only look for a catalog variable
@@NAME@@ - to only look for a global variable
@_NAME_@ - to first look for a catalog variable, falling back to global unless found
Using the [var] tag

DIRECTIVE TYPE AND DEFAULT VALUE

Global directive,
Catalog directive

EXAMPLES

Example: Defining a variable

Variable EMAIL root@mydomain.local

Example: Defining a variable

Variable DOCUMENT_ROOT /usr/local/etc/httpd/htdocs

NOTES

Variable names do not need to begin with a capital letter (unlike the documentation prior to Interchange 5.4 release stated), even though specifying them in all-uppercase is a widely accepted practice.

Variable is available in Interchange versions:
