* calc: Improve handling of invalid 'calc-string-maximum-character'Jacob S. Gordon2026-01-171-56/+16
| | | | | | | | | | | | | | | 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.

* calc: Allow strings with character codes above Latin-1Jacob S. Gordon2025-06-141-0/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (Bug#78528)

* | Calc: speed up math-read-preprocess-string (bug#67536)Mattias Engdegård2023-12-191-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `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.

* Calc: don't treat nil as an integer (bug#40155)Mattias Engdegård2020-03-271-0/+11
| | | | | | | | | | | Make Math-num-integerp return false for nil, following Math-integerp which was changed in the bignum reform. This fixes a crash in calc-graph-fast. Reported by Narendra Joshi. * lisp/calc/calc-macs.el (Math-num-integerp): Not true for nil. * test/lisp/calc/calc-tests.el (calc-Math-integerp): New tests.

| | | | | | | | * lisp/calc/calcalg2.el (math-try-solve-for): To solve Ax^n=0 where A is a nonzero constant and x the variable to solve for, solve x^n=0 instead of solving A=0 (which obviously fails) or something equally stupid. * test/lisp/calc/calc-tests.el (calc-test-solve-linear-system): New.

(math-absolute-from-julian-dt): Use Julian, not Gregorian, leap year rules for counting days within a year. (math-julian-date-beginning, math-julian-date-beginning-int): Change constants to be consistent with their doc strings and the code: use Rata Die epoch at Dec 31, 1 BC Gregorian proleptic, not Julian. * doc/misc/calc.texi (Date Forms): Correct difference between Julian Day and Rata Die. * test/lisp/calc/calc-tests.el (calc-test-calendar): New test.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-3/+3
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
