sciteco/expressions.h, branch v2.5.2

autoconf preparation: move everything into src/ subdir

2012-12-04T21:07:08+00:00

fixed command line termination

2012-11-24T17:19:52+00:00

 * do it only in start state: so double escapes in strings do not cause a termination and an empty string may be specified
 * clear arithmetic stacks on line termination

expressions.find_op(), can be used test whether we are in a loop (although that's inefficient)

2012-11-14T04:39:42+00:00

various arithmetic expression fixes: SUB must have higher precedence than ADD; fixed num_sign (unary minus) handling

2012-11-12T05:26:09+00:00

implemented F<, F>, F' and F| (flow) commands

2012-11-11T06:00:00+00:00

additional commands implemented

2012-11-07T22:06:38+00:00

make some Expression methods private

2012-11-07T19:16:00+00:00

simplified/cleaned up undo operations on value stack

2012-11-07T19:12:18+00:00

 * special undo tokens are private to the ValueStack class and automatically parameterized
 * undo_push() and undo_pop() methods hide the internals of pushing the undo tokens

fixed "," operator

2012-11-07T18:08:15+00:00

instead of pushing a special number (which wasn't that special...), use a dedicated "new" operator which does not count as an argument operator, nor does it count as an ordinary operator and it is popped before any number (and "number" operator) is pushed

expression stack fixes and some arithmetic commands
