<id>bd96450a09fc268fed35c0e8e8e181bed346c770</id>
<content type='text'>
Previously, if 'calc-string-maximum-character' wasn't a valid
character 'math-vector-is-string' would throw an error in the
comparison, leading to an incomplete display of the stack and a
cryptic error message.  Instead, have 'math-vector-is-string'
return nil, which effectively disables the display of strings.
Refines feature introduced in bug#78528.
* doc/misc/calc.texi (Customizing Calc): Update description of
behavior for invalid 'calc-string-maximum-character'.
* lisp/calc/calccomp.el (math-vector-is-string): Return nil when
'calc-string-maximum-character' doesn't represent a character.
* test/lisp/calc/calc-tests.el (calc-math-vector-is-string): Correct
and simplify tests.

<title>calc: Allow strings with character codes above Latin-1</title>
<updated>2025-06-14T14:07:19+00:00</updated>

<name>Jacob S. Gordon</name>

<link rel='alternate' type='text/html' href='https://jason.zzq.org/git/emacs/commit/?id=5bd9fa084dcf0ce8efaaf9212c24addec48d824f'/>
<id>5bd9fa084dcf0ce8efaaf9212c24addec48d824f</id>
<content type='text'>
The current behavior of the functions 'calc-display-strings',
'strings', and 'bstrings' is to skip any vector containing
integers outside the Latin-1 range (0x00-0xFF).  We introduce a
custom variable 'calc-string-maximum-character' to replace this
hard-coded maximum, and to allow vectors containing higher
character codes to be displayed as strings.  The default value
of 0xFF preserves the existing behavior.

* lisp/calc/calc.el (calc-string-maximum-character): Add custom
variable 'calc-string-maximum-character'.
* lisp/calc/calccomp.el (math-vector-is-string): Replace hard-coded
maximum with 'calc-string-maximum-character', and the 'natnump'
assertion with 'characterp'.  The latter guards against the
maximum being larger than '(max-char)', but not on invalid types of
the maximum such as strings.

* test/lisp/calc/calc-tests.el (calc-math-vector-is-string): Add
tests for 'math-vector-is-string' using different values of
'calc-string-maximum-character'.

* doc/misc/calc.texi (Quick Calculator, Strings, Customizing Calc):
Add variable definition for 'calc-string-maximum-character' and
reference thereof when discussing 'calc-display-strings'.
Generalize a comment about string display and availability of 8-bit
fonts.

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.

`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):
