2024.05.01 - GNU nano 8.0 "Grus grus"
• By default ^F is bound to starting a forward search, and ^B to starting a backward search, while M-F and M-B repeat the search in the corresponding direction. (See the documentation if you want the old bindings back.) • Command-line option --modernbindings (-/) makes ^Q quit, ^X cut, ^C copy, ^V paste, ^Z undo, ^Y redo, ^O open a file, ^W write a file, ^R replace, ^G find again, ^D find again backwards, ^A set the mark, ^T jump to a line, ^P show the position, and ^E execute. • Above modern bindings are activated also when the name of nano's executable (or a symlink to it) starts with the letter "e". • To open a file at a certain line number, one can now use also `nano filename:number`, besides `nano +number filename`. • <Alt+Home> and <Alt+End> put the cursor on the first and last row in the viewport, while retaining the horizontal position. • When the three digits in an #RGB color code are all the same, the code is mapped to the xterm grey scale, giving access to fourteen levels of grey instead of just four. • For easier access, M-" is bound to placing/removing an anchor, and M-' to jumping to the next anchor. • Whenever an error occurs, the keystroke buffer is cleared, thus stopping the execution of a macro or a string bind. • The mousewheel scrolls the viewport instead of moving the cursor GNU nano is a simple and easy-to-use editor for on the terminal. https://nano-editor.org/manual.html A concise overview of nano's shortcut keystrokes: https://nano-editor.org/cheatsheet.html The tarball and its signature are here: https://nano-editor.org/dist/v8/nano-8.0.tar.xz https://nano-editor.org/dist/v8/nano-8.0.tar.xz.asc Specific issues that were addressed in this release: https://sv.gnu.org/bugs/?63520 (nano could crash when linting) https://sv.gnu.org/bugs/?63691 (wrong Replace-With help text) https://sv.gnu.org/bugs/?63702 ("{verbatim}" in a bind failed) https://sv.gnu.org/bugs/?63964 (format string vulnerabilities) https://sv.gnu.org/bugs/?64019 (flashing filename with --zero) https://sv.gnu.org/bugs/?64125 (nonstandard synopsis in man page) https://sv.gnu.org/bugs/?64168 (replacing gave unwanted feedback) https://sv.gnu.org/bugs/?64226 (misleading "Unbound key" message) https://sv.gnu.org/bugs/?64340 (URL in C was colorized as comment) https://sv.gnu.org/bugs/?64465 (vanishing folder could cause crash) https://sv.gnu.org/bugs/?64578 (spurious error with --mouse) https://sv.gnu.org/bugs/?64632 (X11 F13 symbol was not understood) https://sv.gnu.org/bugs/?64945 (poor wrapping with long words) https://sv.gnu.org/bugs/?64996 (pasting 39 bytes could hang) https://sv.gnu.org/bugs/?65193 ("specified" was misspelled) https://sv.gnu.org/bugs/?65196 (empty formatter string would crash) https://sv.gnu.org/bugs/?65204 (empty linter string would hang) https://sv.gnu.org/bugs/?65278 (crash after nested search) https://sv.gnu.org/bugs/?65279 (use-after-free during undo) https://sv.gnu.org/bugs/?65289 (heap-buffer-overflow during undo) https://sv.gnu.org/bugs/?65301 (macro could insert unwanted text) https://sv.gnu.org/bugs/?65317 (undoing justification could eat line) https://sv.gnu.org/bugs/?65334 ([wish] recognize also .mjs extension) https://sv.gnu.org/bugs/?65365 (uninitialized value during verbatim) https://sv.gnu.org/bugs/?65369 (crash after search during replace) https://sv.gnu.org/bugs/?65381 (searching overwrote replace string) https://sv.gnu.org/bugs/?65394 (invalid read when typing M-: fast) https://sv.gnu.org/bugs/?65396 ("Missing multidata" when justifying) https://sv.gnu.org/bugs/?65407 (overlong include path could crash) https://sv.gnu.org/bugs/?65426 ("Missing" when undoing justification) https://sv.gnu.org/bugs/?65428 ("Misplaced cursor" for Bsp at EOF) https://sv.gnu.org/bugs/?65435 ("Missing" when justifying a region) https://sv.gnu.org/bugs/?65445 (mis-sized indicator with --softwrap) https://sv.gnu.org/bugs/?65482 ("Missing" when justifying a region) https://sv.gnu.org/bugs/?65501 (no light background on Linux VT) https://sv.gnu.org/bugs/?65505 (setting a color twice leaked memory) https://sv.gnu.org/bugs/?65516 ("Missing" during macro replay) https://sv.gnu.org/bugs/?65560 (confusing feedback when converting) https://sv.gnu.org/bugs/?65565 (reading from stdin was undoable) https://sv.gnu.org/bugs/?65586 (misadjusted mark with --autoindent) https://sv.gnu.org/bugs/?65591 (new Makefile did not use syntax) https://sv.gnu.org/bugs/?65604 ("Span underflowed" for a hard-wrap) https://sv.gnu.org/bugs/?65611 ("Span underflowed" for redo of wrap) https://sv.gnu.org/bugs/?65636 (--break with --zap could crash) https://sv.gnu.org/bugs/?65649 (on laggy machine macro could hang) Almost half of these issues were reported by `correctmost`, who has been generating scripts that hammer nano with random keystrokes.
