This is mainly a bug fix release.

What’s Getopt::Declare?

It is yet another command-line parser, that uses regular expressions  
in its engine. It is designed to be extremely easy to use, but very  
powerful.

Example:

require “Getopt/Declare”  
args = Getopt::Declare.new(\<\<‘EOF’)

-q, --quiet quiet  
-f, --files files:if… input files  
-n, --number num:n a float number  
-i, --integer num:i an integer number

EOF

p args[‘-q’]  
p args[‘-f’]  
p args.unused

What’s new:

1.23 - \* Added all samples as Ruby unit tests, which lead to the  
discovery  
of some bugs.  
\* Fixed silly bug with foundid that would make some parsing not  
work (required parameters).  
\* Fixed a silly bug when parsing from a string file, which  
would  
modify the string in place  
\* Fixed a bug in that would make it not parse Rh+ and Rh- in  
cmdline\_pvttype demo and other potential regexes.  
\* Removed 3 warnings from parsing multiple times.  
\* Fixed a bug with cluster: singles not working.  
\* Fixed a stack trace bug with optional single text arguments.  
\* Improved handling of optional integer/float arguments,  
leaving  
them as nil instead of 0 as before.  
\* Added ‘used’ function to allow returning the flags that are  
used.  
\* Made CSV demo work again, albeit I am not too happy with the  
regex.

Neat-o. Thanks, gga. I learned something new from your example code  
too… that having a closing paren around the start of a heredoc  
string is OK. Cool!
