* lisp/calc/calc-prog.el: Switch to new method of detecting end of kbd macro

2024-03-10T14:40:19+00:00

'read-char' will no longer return -1 as of
ac82baea1c41ec974ad49f2861ae6c06bda2b4ed. This switches to a cleaner
method of detecting whether the end of a keyboard macro has been
reached.

* lisp/calc/calc-prog.el (calc--at-end-of-kmacro-p): New function.
(calc-kbd-skip-to-else-if): Use the function.

Calc parses fractions written using U+2044 FRACTION SLASH

2024-01-27T14:42:47+00:00

Fractions of the form 123⁄456 are handled as if written 123:456. Note
in particular the difference in behavior from U+2215 DIVISION SLASH
and U+002F SOLIDUS, which result in division rather than a rational
fraction.
* lisp/calc/calc-aent.el (math-read-replacement-list): Substitute a
colon for any fraction slash.  (Bug#66944)

* test/lisp/calc/calc-tests.el (calc-frac-input): Test various
fraction types.

* etc/NEWS:
* doc/misc/calc.texi (Fractions): Mention fraction slash, precomposed
fractions.

Calc: speed up math-read-preprocess-string (bug#67536)

2023-12-19T16:11:07+00:00

`math-read-preprocess-string` is one of the bottlenecks of `calc-eval`
and was unnecessarily slow even with no substitutions made.
This affected org-mode in particular, where `calc-eval` is called
repeatedly to recalculate tables.

Reported by Raffael Stocker who also wrote the unit tests here.

* lisp/calc/calc-aent.el (math--read-preprocess-re-cache): New.
(math-read-preprocess-string):
Use math--read-preprocess-re-cache, first computing it if necessary.
* test/lisp/calc/calc-tests.el (calc-math-read-preprocess-string):
New test.
