Arnold Pizer (1):
Set file and directory permission so that a WeBWorK admin can run remove_stale_images to remove old tmp images. Currently you have to be root to run this.
Davide P. Cervone (43):
Fix typos in comments
Fix differentiation of names constants, and add rules for dot and cross products
Fix name of Matrix context
Fix typos in comments
Fix typos in comments
Don't turn an undefined value into a MathObject
Merge branch 'differentiation'
Update POD documentation to include new flags, classes, and information about custom answer checkers. Format everything better using code, item, etc. Update samples problems and extensions. Remove unneeded differentiation macros (since now part of core MathObjects) and outdated answer-checker example, since checker option is much better.
Fix typo in comments
Improve paren position in one place, and remove unneeded comments
Merge branch 'docs'
Added missing =over
Fix a typo in the comments
Protect more characters in pattern for tokens (in particular, ^ and $)
Add Complex-Point, Complex-Vector, Complex-Matrix contexts
Add support for complex matrices, M^-1, M^-n, ~M
Merge branch 'docs'
Merge branch 'checkers'
Fix problem with ans_array where CSS for margins caused it to always be on a separate line
Add solve and order methods, since MathObjects take care of the LR part automatically
New macro files that add transpose, trace, determinant to Matrix contexts and conjugation to Complex contexts
Merge branch 'openwebwork/master' into 'dpvc/master' and resolve one line conflict
Add comment about lists being overridden in Parser/Context.pm
Allow vector functions to mark results as vectors, and make sure unit() is handled that way. Mark function of a constant as constant even if reduceConstantFunctions is false.
Move cmp_call_filter to Value package so ALL classes can use it, not just Formulas
Mark domainMismatch if student values can't be computed (used to only be done if checkUndefinedPoints was true). Use checkUndefinedPoints as a Context flag (like it is supposed to be), not just a property of the correct answer.
Make Compute($f,x => c) set up correct_ans and original_formula properly (note that equation is still the original unsubstituted formula)
Fix comments now that they are in POD format
Merge branch 'master' of https://github.com/openwebwork/pg-dev
Fix problem with detecting NAN when it is capitalized or negated
Fixed typo in comments
New OneOf MathObject for creating answers that can be one of several correct values.
Fix typo in comment.
Add parserFunctionPrime.pl macro file that implements prime notation for parserFunction objects.
Remove 'defined' from deprecated defined(@array) in MathObjects (resolves issue #17).
Use getVariableLimits to get limits for diagnostic graphs (so that they are handle the same way as the answer checking itself)
Fix some typos in the comments for PGML.pl
Prevent loading PGML.pl from setting the context to Typeset
Fix typos in comments for parserFormulaUpToConstant.pl
Add new parserFormulaAnyVar.pl file to allow formulas that a student can enter using any variable name
Put contextLimitedPolynomal and contextInequalities back into one file (since the problem that caused these to be broken into separate pieces was resolved by SHA d636150 in openwebwork/webwork2-dev). Note that these libraries need to be removed from the library list in the configuration file for webwork2.
Update unionTables and unionLists to not use the obsolete LaTeX2HTML mode (removes references to eHTML and bHTML, so resolves #2043 and #2421)
Remove unneeded x permissions from three macro files
Djun Kim (19):
Removing comments referencing dangerousMacros.pm as this file was removed. Removed unrestricted load of dangerousMacros.pm from CourseScriptsDirectory. This may break existing problems that use this mechanism; there should be a different, better way to address this (probably very rare) use case.
Corrected reference to dangerousMacros.pl in error messages
Removed commented-out code originally derived from dangerousMacros.pl. Removed references to dangerousMacros.pl from the documentation.
Fixed documentation and removed spurious references to dangerousMacros.pl
Fixed up HTML generation; layout of code
Cleanup HTML generation; code layout. Remove spurious references to dangerousMacros.pl. Fix POD errors.
Remove reference to dangerousMacros.pl.
Remove reference to dangerousMacros.pl.
Remove reference to dangerousMacros.pl.
Remove reference to dangerousMacros.pl.
