5a9c5f681b clean up ascii art => unicode a little 
adjust the way it changes characters so it
doesn't change them when they are already the right
thing (this means set-modified is not always called
and also improves performance in the case that little
changes in a big diagram)

set-label-visible is really a boolean and make some of the

58e15cc2c7 fix tests for the "class:"-less object-name results 2012-12-22 18:25:43 -06:00
Robby Findler
b112a7ef0a adjust object-name on classes and interfaces to drop the prefix 
Before this commit, things like this:

  (define c% (class object% (super-new)))
  (object-name c%)

would produce

   'class:c%

but now classes and interfaces will be more like procedures and, in
the example above, just produce:

   'c%

The underlying goal is to make error messages generated from contracts
like

  (is-a?/c frame%)

have "(is-a?/c frame%)" in the message, instead of "(is-a?/c
class:frame%)"

a09c8f1857 Revert "racket/draw: fix another problem with the JPEG binding" 
This reverts commit c2468f1f9a.

The libjpeg documentation claims that it has no static state,
so atomic mode shouldn't be necessary. Also, the stress test is
still failing on some platforms, so there must be a different
problem than I thought.

1aebd171c5 Moar matrix review/refactoring 
* Consolidated Gauss and Gauss-Jordan elimination

* Fixed Gaussian elimination to return all indexes for pivotless columns,
  not just those < m

* Consolidated `matrix-row-echelon' and `matrix-reduced-row-echelon'

* Specialized row reduction for determinants; removed option to not do
  partial pivoting (it's never necessary otherwise)

* Added `matrix-invertible?'

* Removed `matrix-solve-many'; now `matrix-solve' solves for multiple
  columns

* Gave `matrix-inverse' and `matrix-solve' optional failure thunk arguments

* Made some functions that return multiple columns return arrays instead
  (i.e. `matrix-column-space')

* Added more tests

this may not be suitable code for RoR, I'm not sure, but it
avoids the compilation problem and was fun to try out
(at least for me)

use these files to determine if a file is dirty (and thus needs
to be recompiled) when another file is saved.
