* ; Minor changes to 'truncate-string-pixelwise' (bug#80244)Stéphane Marks2026-02-071-0/+10
| | | | Fix two bugs and add tests for them.
* New function 'truncate-string-pixelwise' (bug#80244)Stéphane Marks2026-01-311-0/+80
| | | | | | | | | | | | | | | This function will truncate a string on a pixelwise basis in a work buffer and using a binary search rather than brute force. * lisp/emacs-lisp/subr-x.el (work-buffer--prepare-pixelwise): New defun helper function. (string-pixel-width): Use the helper function. (truncate-string-pixelwise): New defun. * test/lisp/misc-tests.el (misc-test-truncate-string-pixelwise): (misc-test-truncate-string-pixelwise-unicode): New test. * doc/lispref/display.texi (Size of Displayed Text): Document the function. * etc/NEWS: Announce the function.

* Fix `string-pixel-width' with alternate text propertiesDavid Ponce2025-03-201-0/+64
| | | | | | | | | | | | Fix possible wrong result of `string-pixel-width' with alternate and default properties. Create new regression tests. * lisp/emacs-lisp/subr-x.el (string-pixel-width): Like for `face-remapping-alist', use in work buffer the value of `char-property-alias-alist' and `default-text-properties' local to the passed buffer, to correctly compute pixel width. (Bug#77042) * test/lisp/misc-tests.el: Add tests for `string-pixel-width'.

* Add duplicate-dwim (bug#56418)Mattias Engdegård2022-07-261-0/+38
| | | | | | | | | | | | Like duplicate-line but duplicates the region instead if active. Rectangular regions are duplicated on the right-hand side. The region remains active afterwards, to facilitate further duplication or other operations on the same text. * lisp/rect.el (rectangle--duplicate-right): * lisp/misc.el (duplicate-dwim): New. * test/lisp/misc-tests.el (misc--duplicate-dwim): New test. * etc/NEWS: Announce.
* duplicate-line: fix optional argument and add test (bug#46621)Mattias Engdegård2022-06-221-0/+16
| | | | | | | | | The test assumes that the current semantics are intended and desired, which may or may not be true, but it's better than not having any at all. * lisp/misc.el (duplicate-line): Don't crash if called with no argument. * test/lisp/misc-tests.el (misc--duplicate-line): New test.
* zap-to-char: case sensitive for upper-case charactersTino Calancha2022-05-211-1/+8
| | | | | | | | | | | | | | | | | In interactive calls, behave case-sensitively if the given char is an upper-case character. Same for zap-up-to-char (Bug#54804). This is analog to what the user-level incremental search feature does. * lisp/misc.el (zap-up-to-char): Add an optional arg INTERACTIVE. Perform a case-sensitive search when INTERACTIVE is non-nil and CHAR is an upper-case character. * lisp/simple.el (zap-to-char): Same. * etc/NEWS (Editing Changes in Emacs 29.1): Announce this change. * test/lisp/misc-tests.el (misc-test-zap-up-to-char): Add test cases. * test/lisp/simple-tests.el (with-zap-to-char-test): Add helper macro. (simple-tests-zap-to-char): Add a test.
