• Release 1.041.
• This is a small maintenance release that is mainly for improving documentation. Similar maintenance releases are being done with all of my distributions simultaneously. A lot of it was formatting issues that were easy to miss before; the other bullet points below list the non-formatting issues. These files had formatting fixes: ParamParser.pm, ChangeLog.
• The distribution file layouts have also been standardized, with modules going in a "lib" folder and tests going in a "t" folder. "test.pl" was changed to "t/Class-ParamParser.t" and "ParamParser.pm" was changed to "lib/Class/ParamParser.pm".
• Updated NAME in ParamParser.pm to match the official registered module list.
• Updated all Copyright statements to a better (and longer) version, which is dated 1999-2003. Your rights to use these modules haven't changed, but they may now be easier to understand. These statements appear once in the ReadMe file at the bottom (under "AUTHOR"), and twice in each module (.pm file), a full version at the bottom (under "AUTHOR") and a shorter version at the top (in code comments).
• Added the "use warnings" pragma at the top of all files beside "use strict"; every occurance of "use strict" gained a "use warnings" whether it was in the module proper or in its test script or in its SYNOPSIS. This should save users from having to put -w on the command line for them.
• Incremented the module $VERSION number by 0.0009, and all test scripts to require the new version. Also, where any of my modules use others of my modules, they now require the latest version as of this writing, for simplicity of maintenance.
• Updated all test scripts to read $verbose from @ARGV (command line arguments), and other test script improvements.
• Updated these sections of the ReadMe file: INSTALLATION.

• Release 1.0401.
• Corrected a warning that appears when converting a positional SOURCE to named where SOURCE has more array elements than NAMES. While the correct result was returned all along, warnings can be annoying in this context. Thanks to Laurie Shammel <lshammel@imt.net> for alerting me to this.

• Release 1.04.
• This module has been reorganized internally by separating its core functionality into a set of private methods: argsare_named(), positto_named(), namedto_posit(), renamenamed_args(). The two public methods, params_to_hash() and params_to_array() make use of these as much as possible and otherwise handle their proprietary details on their own.
• The above changes were made in preparation for merging this module with other existing named-arguments modules to produce a new standard module. Of course, there is a chance nothing will happen, in which case this module is simply better organized now than before, as well as easier to subclass.
• The pseudo-public method params_to_hash_or_array() no longer exists, so any code that calls it directly will break. No one should have been using it directly anyway, as it was just to implement the other public methods. The count of tests was reduced to 90 from 92 as the two missing ones called the removed method directly.
• Named arguments being renamed are now moved into a second hash during the process rather than being re-inserted into the one they came from. As a result, some name-collisions may result in one value overriding the other instead of the reverse. Note that the results of collisions are now easier to predict than before. This change affected two test results, which have been updated to make the new way correct. Of course, you should never set up your renaming such that there are collisions anyway.

• Release 1.03.
• This release fixes issues discovered by cpan-testers@perl.org, as detailed in brief below.
• Renamed some included files to "Makefile.PL", "test.pl", and "MANIFEST". Due to the case-sensitivity of some systems, it is like the files aren't there otherwise.
• The RENAME hash is now iterated over in the order of "sort keys %hash" instead of "keys %hash". This ensures that renaming pairs are always evaluated in the same order across different Perl installs (given the same hash, "keys %hash" returns its results in a different order on some systems than on others). During normal use, this wouldn't affect anything, because one isn't supposed to be renaming one key to the same thing another is renamed from. But in the odd circumstance that one is doing that, it does make a difference in which order "a->b,c->a" is evaluated.
• The serialize() function inside "test.pl", that I use to stringify the multi-dimensional data structures it needs to compare, has been modified such hashes are now serialized in the order of "sort keys %hash" instead of "keys %hash". This change was prompted by test failures on one system due to the fact that equal hashes were serializing in a different order across systems, so the comparisons as scalars didn't always match.
• Improved the install instructions in my ReadMe file.

• Release 1.02.
• This release is the first one that includes the CPAN standard files "MakeFile.pl", "Test.pl", and "Manifest", which were all created following the previous release. "Test.pl" was used to discover several bugs that my production use of the modules didn't; their fixes are detailed below. The content of "Manifest" was previously inside the "ReadMe" file.
• Added a third method, params_to_hash_or_array(), which is now used to implement both of the existing methods; this eliminates an 80% redundancy in their code. The first argument of the new method says which of the original two, params_to_hash() or params_to_array(), it acts like.
• Added a sixth argument to all methods, which lowercases (makes case-insensitive) named source parameters when true, for easier matching.
• Added programmer documentation to the various blocks of code, so it is easier to see how they work; useful because a lot is done with little code.
• Fixed bug where RENAME failed to match parameters for renaming to "", which is the explicit signal to delete them.
• Any SOURCE that has an odd number of elements will now be interpreted as positional format; previously, SOURCE needed to have exactly one element for this to happen. As before, tests for named format have higher precedence, so a SOURCE whose first element is either a hash or starts with a "-" is considered named regardless of the number of elements in SOURCE. This change fixed a bug causing an "Odd number of elements in hash list" warning when an odd number of SOURCE elements was interpreted as named format; however, that warning will still appear with an odd list starting with "-".
• If there are multiple "remaining" values in SOURCE, they are now all returned rather than just the first one. See the parameter documentation for REM for details. This means that previously ignored second and third "remaining" values will cause the return value for REM to be an array ref instead of a scalar, so your code may have to check for this.
• Fixed bug where NAMES defaulted to a single value of "" when it should have defaulted to an empty list; this had resulted in params_to_array() always returning a value when it should have returned none.
• Fixed bug occurring when we make positional output from an empty SOURCE whereby the output is an array containing "undef" values; the count of these values was the same as the number of values in NAMES; now the returned array is empty as it should be.

2001-01-01 Darren Duncan <perl@DarrenDuncan.net>

• Release 1.01.
• This release is the first one following official registrations with "The Perl 5 Module List". The updated entry would look like this:

Class::
::ParamParser bdpO Provides complex parameter list parsing DUNCAND

• Module POD has been significantly updated, particularly in the Synopsis section, and the ReadMe file was overhauled.
• There were no changes to the code itself.

2000-08-26 Darren Duncan <perl@DarrenDuncan.net>

• Release 1.0.
• This release contains my "Class::ParamParser" module which was previously a part of my "libdwg" distribution, but I have set it off on its own for those of you who only want to use this and not the other modules.
• This module contains complete POD within it.
• This module requires Perl version 5.004.

2000-08-23 Darren Duncan <perl@DarrenDuncan.net>

• libdwg 1.0, the first version of any distribution to include Class::ParamParser, was released on CPAN.

2000-04-21 Darren Duncan <perl@DarrenDuncan.net>
