* Use proper function pointer type instead of void *jca2020-05-081-5/+7
| | | | | | | | | | Mixing up function and void pointers isn't defined by POSIX or the C standard. POSIX only specifies that casting the result of dlsym(3) to an appropriate function pointer works. Avoid all this by using a typedef. from Michael Forney, ok tb@
* Bind ^L (C-l) to clear-screen instead of redrawjca2019-04-031-2/+2
| | | | | Slightly more useful for some, same defaults as bash. No objection deraadt@ phessler@, ok tb@ kn@ benno@
* Add clear-screen emacs editing command, currently not bound to amillert2018-06-181-6/+31

* Back out sign compare changes that appear to cause problems on hppa.millert2018-01-041-4/+4
| | | | Requested by deraadt@
* Add WARNINGS=yes to ksh and fix the resulting sign compare warnings.millert2018-01-011-4/+4
| | | | OK tb@
* Add -Wshadow to Makefile and fix the resulting warnings. Many ofmillert2017-12-271-3/+1
| | | | | | | the warnings are due to the use of globals with generic names, specifically "options" and "path". I've renamed "options" to "sh_options" since it holds the shell options and "path" to "search_path". OK jca@ tb@
* Add another pair of home/end key bindings; from Lari Rasku.anton2017-12-181-1/+3
| | | | ok jca@
* Remove the "version" interactive function in emacs mode.jca2017-11-261-32/+1
| | | | Not bound by default and not very useful. ok schwarze@ anton@
* Fix some incorrectness related to Emacs editing mode in ksh:anton2017-11-221-3/+3
| | | | | | | | - Keep the order of bindings in sync between the manual and implementation - Fix wrongly documented bindings in the manual - Break out commands without a default binding in the manual ok jmc@ tb@
* Stop exposing the emacs-usemeta option, and warn when trying to set it.jca2017-08-301-4/+1
| | | | | Unused since 2012, to be removed after 6.2. Input from anton@, ok anton@ millert@

* Kill a useless setlocale() queryjca2017-08-291-11/+3
| | | | | | | | Pointless since the removal of the setlocale() call in main.c:rev1.82, the emacs-usemeta flag isn't used in the code since 2012. This kills a chunk of code in a statically linked ksh. ok millert@
* No need to NUL-terminate the line buffer since it's handled by x_e_getu8() byanton2017-06-251-3/+1

* Don't output partial UTF-8 characters in ksh emacs mode. Instead, try to read aanton2017-06-251-12/+52
| | | | | | | | | complete UTF-8 character first. Fixes an issue while running ksh in tmux where UTF-8 characters inserted in columns other than the last one are discarded. With help from nicm@ and schwarze@ who also wrote the UTF-8 validation, thanks! ok schwarze@
* '^T' is documented to be bounded to transpose-chars while in emacsbrynet2017-06-201-40/+1
| | | | | | | | | | mode, not "stuff". While here, remove the poorly described "stuff" and "stuff" bind functions as well.. In the unlikely event anyone has those in .kshrc, they'll need to be removed. ok anton@
* Improve UTF-8 handling on lines that are wider than the terminal,schwarze2017-05-121-2/+4
| | | | | | | | | | | | | | in two respects: 1. During output in x_e_putc(), when counting display columns, skip UTF-8 continuation bytes. Fixes backward movements that cause horizontal scrolling. 2. After deleting characters, recalculate the last byte that fits on the line. Patch from <Anton dot Lindqvist at gmail dot com> on tech@. OK millert@ tb@
* In emacs incremental search mode (^R),schwarze2016-08-091-3/+4
| | | | | | make commands starting with the escape key (^[) work as documented. Long-standing bug, this time reported by Dave minus Cohen dot com. OK natano@ halex@

* Next step in UTF-8 support:schwarze2016-01-081-3/+9
| | | | | | | | | | | | | 1. Improve all functions involving words by allowing non-ASCII characters to be part of words. 2. Allow insertion of non-ASCII characters without screwing up the display, by backing up to the start byte after inserting a continuation byte, and starting to re-print there. 3. Fix forward movement which i didn't get quite right in my previous commit: Always advance to a start byte, never to a final continuation byte, or the next insertion would split the character in the middle. OK mpi@

* Move system headers from sh.h to those files that actually need them.tb2015-12-141-1/+3
| | | | ok mmcc@ a while ago
* In emacs command-line editing mode, make sure that moving left andschwarze2015-12-101-5/+24
| | | | | | | | | right can only move by whole characters, not into the middle of a character, and that deleting characters can only delete characters whole, not individual bytes out of characters. Based on parts of a patch by Frederic Nowak <fnwk at mailbox dot org>, tweaked by me. OK tedu@ semarie@ mpi@
