Revision history for Perl extension Physics::Unit.

0.04

• Changed several tests in unit.t to use RE matches instead of exact numerical equality for floating point numbers. This should fix the failures that I got from some of the Perl testers on other platforms.

0.03

• Took out "print 'Howdy!'" from Unit.pm:ooops ! I had put that in there to make sure that when developing, I was using the correct copy of the module.
• Removed the example script MultiTypes.pl. It didn't really do anything unique.
• Simplified eg/UnitSimple.pl, and moved some of its test code into t/unit.t.
• Created eg/UnitDebug.pl, which turns on debugging when given the '-d' command-line option. I took this feature out of UnitSimple.pl, in order to make the latter as simple as possible.
• Similarly, I created eg/VectorDebug.pl, and simplified eg/VectorSimple.pl.
• Ditto for eg/ScalarDebug.pl and eg/ScalarSimple.pl.
• Fixed eg/ScalarMethods.pl - changed "lb" to "lbm" in the mass.
• Added lots of tests to t/scalar.t: everything that was in eg/ScalarMethods.pl and eg/ScalarSimple.pl.
• I took all the test statements out of the examples: things like "die if ...". This cleans up the examples. Wherever it made sense, I moved those tests into the test scripts, and converted them to use the Test::More functions.
• Added an example of automagic determination of a scalar type to the Scalar.pm documentation.
• I fixed the automatic generation of scalar type. This example from the Scalar.pm documentation: $d = new Physics::Unit::Scalar('3m'); now correctly produces a Physics::Unit::Distance object.
• That resulted in the VectorSimple.pl example script working now.
• Changed the header of one of the sections in the Scalar.pm documentation from "IMPLEMENTATION NOTES" to "UNITS ASSOCIATED WITH SCALARS".
• Added UnitsByName.html and UnitsByType.html to the MANIFEST. These are generated automagically by the UnitGenDoc.pl example script.

0.02

• Added the prefixes "semi" and "demi", for 0.5.
• Added the binary prefixes; see http://physics.nist.gov/cuu/Units/binary.html
• Added 'revolution', 'revolutions', and 'rpm'.
• Added 'cycle' and 'cycles'.
• Added 'degrees-rankine'
• Removed some old code that was commented out.
• Moved implementation-specific comments, including private method documentation, into UnitImpl.pm.
• Added the "EXPRESSION GRAMMAR" section to Unit.pm.
• Moved documentation about Scalar.pm private methods into ScalarImpl.pm.
• Added "pica" and "point" units to Unit.pm
• Also added "stone" and "stones"
• Also added jeweler's units 'carat', 'carats', 'karat', 'karats', and 'j-point'.
• Added a section to the Unit.pm documentation: "Naming Conflicts and Resolution". This describes all of the instances of units names that have multiple definitions (e.g. "point") and how each is resolved in this library.
• Improved the documentation of the unit expression grammar.
• Re-organized, slightly, the documentation of private methods in the Unit.pm module.
• Re-organized, slightly, the documentation in the Scalar.pm module.
• Changed all the files' newline format from DOS to Unix.
• Updated the README file.
• Unit.pm Documentation
  • Removed the "COMPILE-TIME STUFF" header and the associated paragraph.
  • InitBaseUnit() is showing up both under "Class Data" and "Public Utility Functions". I removed it from the former.
  • Ditto for InitPrefix(), InitTypes(), InitUnit(), and GetUnit(). Gene: was there some reason that I'm not seeing for including these under "Class Data"?
  • Added some of the grammar back into the documentation for the Parser methods.
• Scalar.pm Documentation
  • I added the header "IMPLEMENTATION NOTES" two paragraphs after the "DEBUG OPTION" header, since the following paragraphs there aren't related to the debug option.
  • I took the ScalarFactory() function out of "PUBLIC METHODS", and put it under "PUBLIC UTILITY FUNCTIONS" (a new heading).
