believe the following are difficulties with converting WeBWorK 1.x
problems to WeBWorK 2.0.1. (That is, I copied a bunch of WeBWorK 1.x
files which we were using last year into WeBWorK 2.0.1 courses, and had
to change the following to get the problems to compile.)
image() when used between BEGIN_TEXT and END_TEXT gives an error about
the underbar in the parameter tex_size when that is included. If
image() is used outside of the problem text it appears to be fine,
image() fails to find image files named something.other.gif, I believe
because the pattern matching isn't greedy enough; if my memory serves
me correctly, it complains about not knowing what to do with files of
type other.gif or something like that.
str_cmp() returns errors when the filters trim_whitespace or
ignore_case are provided. I think those are default, but I was finding
that the problem was being rejected until I took the filters out.
