libstring-expand-perl - 0.04-3 main

String::Expand implements utility functions for expanding embedded variables
in a string. Variable references are embedded in strings in a similar form to
the Bourne shell, namely, in the form $NAME or ${OTHER_NAME}. In the former
case, the NAME must consist of a capital letter or underscore, and may be
followed by zero or more capital letters, digits or underscores. In the
latter case, the name can consist of any characters, but will be terminated
by the first close brace character '}'.
.
This is especially useful if you want to expand environment variables
inside strings.
.
The string may also contain literal dollar marks, escaped by \$, and literal
escape marks, escaped by \\. These will be converted to $ and \ respectively
on return.
.
While there are many other modules that also provide expansion such as this,
this module provides the function expand_strings(), which will perform
variable expansions in all the values in a given hash, where values can refer
to other values within the same hash.
