Revision history for Perl extension Math::Symbolic.
0.109 Fri Jul 18 00:34:00 2003
- Documentation patches.
- Added signature attribute to variables.
- Added signature() method to all tree elements.
- Added set_signature() method to variables.
- Some docs for the sig. changes.
- Tests for the sig. changes.
- Modified parser to parse unknown 'function(list)' constructs
as variables and their signatures.
- Tests for the parser changes.
- Documentation for the parser changes.
- Added some bad examples to the parser man-page.
0.108 Wed Jul 16 22:41:01 2003
- Added Math::Symbolic::Compiler (as a modified to_sub.pl).
- Modified value() semantics to optionally take arguments.
- Added set_value() method.
- Added lots of docs.
- Added some tests.
- TODO milestones met with this release:
+ Refactor the to_sub.pl code to a package that allows to
compile Math::Symbolic trees to subroutines and/or code.
0.107 Sun Jul 13 21:25:29 2003
- Fixed tests. (Note to self: recreate MANIFEST for dists.)
0.106 Sun Jul 13 19:56:29 2003
- Modified the parser to parse unknown identifiers as variables.
- Modified Operator constructor to send operands through the parser
if they aren't valid Math::Symbolic::* objects.
- Added and fixed docs. A lot.
- Added tests.
0.105 Wed Jul 9 18:56:33 2003
- Added several important items to the TODO.
- Accepted the fact that the TODO is growing faster than the code base.
- TODO milestones met with this release:
+ Add reasonable overloaded interface for arithmetic
operators and some mathematical functions as far as feasible.
+ Overloaded interface for exp, sqrt, log, +,-,*,/,**.
+ Overloaded interface for boolean context and stringification.
+ O. i. for unary minus
+ O. i. for trig functions
+ Overloaded interface for numerical context.
+ Tests for the above.
+ Documentation for the above changes
0.104 Sat Jul 5 19:17:00 2003
- Added to_sub.pl to the distribution. (Math::Symbolic -> Perl sub
compiler.) This is just a proof-of-concept.
0.103 Thu Jun 26 15:08:12 2003
- Fixed test errors.
- Added (very little) documentation.
0.102 Wed Jun 25 21:04:41 2003
- Added overloaded interface for arithmetic operators, exp, log,
sqrt, boolean context, numerical context, sin, cos, mutators.
- Added tests.
- Added docs.
0.101 Fri Jun 20 15:45:10 2003
- Documentation fixes
0.100 Fri Jun 20 01:32:32 2003
(Yep, I hack at random hours.)
- Implemented hyperbolic sine, h cosine.
- Implemented partial derivatives for h sine, h cosine
- Amended parser for h sine, h cosine.
- Same for tangents
- Myriad of bugfixes
- ExportConstants now includes (and exports) PI and EULER constants.
- Renamed class data in M::S::Operator.
- Cotangent.
- Arc sine, arc cosine, arc tangent, arc cotangent.
- Hyperbolic area sine, h. a. cosine
- Tests for the above.
- Broke the parser badly.
- (much later) Fixed it again.
- Some more documentation
- Renamed test files
- TODO milestones met with this release:
+ Add sine/cosine
+ Amend parser to parse sine/cosine.
+ Add sinh/cosh or at least allow the user to use them in the
input string to the parser and have them replaced with
(e^x ± e^-x)/2
+ Amend parser to parse hyperbolic sine/h. cosine.
+ Add tan, arctan, arcsine, arccosine
+ Amend parser to parse tan / arctan, arcsine / arccosine.
+ Find a more reasonable naming scheme for class data and
rename appropriately.
+ Add tests for the new features.
