Introduction

The WeBWorKTeam is pleased to announce the release of PG 2.3.2. This version builds on PG 2.3.1, adding several bug fixes and low-impact feature enhancements. Changes include:

  • MathObjects: Use Perl reals rather than MathObjects reals for adaptive parameters in matrices.
  • MathObjects: Add a new operator // to be the same as / except its TeX form is a/b rather than \frac{a}{b}. This makes it possible get horizontal fractions in exponents, for example, where vertical fractions often don't look so good.
  • MathObjects: Fix a problem with the TeX representation used in previewing students' answers. (Specifically, a + b would be represented as a\quadb. Now it is represented as a \quad b.)
  • MathObjects: Fix a problem with the custom list checker.
  • MathObjects: Added a Vector2D context that has i and j defined as vectors in 2-space so that they can be used to generate vectors in 2D. This avoids students getting the "incorrect number of coordinates" error.
  • MathObjects: Modified the way the Parser-based versions of the traditional answer checkers get copies of their contexts. They now use a new method getCopy to obtain the copy either from the problem's context table or the default table (rather than only from the default). That way the instructor can use parserCustomization.pl to customize the contexts used by the answer checkers.
  • MathObjects: Clear the error message in Context before it is used in an answer checker (prevents bleeding of one error into a later answer).
