With higher values of 'calc-string-maximum-character', rules
made up of glyphs of non-unit width can be the wrong length.
Calculate the number of characters in the rule based on the
display width, rounded up to the nearest integer. Refines
feature introduced in bug#78528.
* lisp/calc/calccomp.el (math-comp-simplify-term): Calculate
rule width with a ratio of 'string-pixel-width's.
With higher values of 'calc-string-maximum-character' the
string length can differ from the displayed width. Calculate
alignment offsets based on the the display width, rounded up to
the nearest integer. Refines feature introduced in bug#78528.
* lisp/calc/calccomp.el (math-comp-width): Replace 'length' with
a ratio of 'string-pixel-width's.
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.
* doc/misc/calc.texi (Customizing Calc): Document the new option.
* etc/NEWS: Document the new option.
* lisp/calc/calc.el (calc-inhibit-startup-message): New option to
inhibit Calc’s startup message.
(calc): Respect the option in Calc’s startup code.
* test/lisp/calc/calc-tests.el (ert): Require ert-x for
'ert-with-message-capture'.
(calc-inhibit-startup-message): Test the new user option.
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.

* lisp/calc/calc-trail.el (calc-trail-kill): Remove the check
preventing the removal of the first trail line, which is no
longer relevant since commit 8e1376a391. (Bug#77816)
* lisp/calc/calc-ext.el (calc-init-extensions): Autoload calc-math
for math-ln-10.
* lisp/calc/calc-units.el (math-standard-units): Use new ln10
constant instead of ln(10) in the decibel definition.
(math-find-base-units-rec): Allow ln10 in expression.
(math-to-standard-rec): Recognize the ln10 constant. (Bug#75861)
* lisp/calc/calc-ext.el (calc-execute-extended-command): Use
M-x's ':affixation-function' to show the keybinding of the calc
command next to its name. (Bug#74829)
* lisp/calc/calc.el
(calc-embedded-open-close-new-formula-alist): Remove previously
introduced quotation marks, as they bring the width of the doc
string past 80.
'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.

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.

New test.
* lisp/calc/calc.el (touch-screen-display-keyboard):
* lisp/minibuffer.el (clear-minibuffer-message):
* lisp/term.el (touch-screen-display-keyboard): Declare
touch-screen-display-keyboard before binding or setting it.
* lisp/loadup.el: Don't autoload touch-screen.el outside X and
Android.
* lisp/touch-screen.el: Autoload functions called from commands
responding to touch screen events.
* lisp/calc/calc-units.el (math-standard-units): Update to 2018
CODATA adjustment. Use exact value for V0. Update some spellings,
e.g. "Planck constant" instead of "Planck's constant".

Immediately after `calc-mode' opens the minibuffer for input
(because you typed a digit, "e", etc), pressing backspace
should clear the minibuffer and return you to the *Calculator*
buffer. Instead, it leaves the minibuffer as-is and prints the
message "Text is read-only"; this is because the function used,
`erase-buffer', tries to erase the read-only minibuffer prompt.
Using `delete-minibuffer-contents' fixes this, since it doesn't
attempt to delete the prompt.
* lisp/calc/calc.el (calcDigit-backspace): Use
`delete-minibuffer-contents' instead of `erase-buffer'. (Bug#67395)
