Martijn Dekker 13c3fb21e9 emacs, vi: Support repeat parameters to VT220 keys (re: f2a3f4e3) ... In the vi and emacs line editors, repeat count parameters can now also be used for the arrow keys and the forward-delete key. E.g., in emacs mode, <ESC> 7 <left-arrow> will now move the cursor seven positions to the left. In vi control mode, this would be entered as: 7 <left-arrow>. src/cmd/ksh93/edit/emacs.c: - ed_emacsread(): Upon getting ^[ (ESC), save current repeat count in a new variable; restore and reset it upon the next character. - escape(): Minor bugfix: when processing a ^[[x sequence where 'x' is a character other than '~' (which would be DEL), also reinsert the final character into the buffer so scripts can detect them. src/cmd/ksh93/edit/vi.c: - cntlmode(): Do not reset the repeat count if the command is '[', the character following ESC in VT220 escape sequences. - mvcursor(): * Do not use getcount() to get the character following '[', as that was parsing repetition parameters in the wrong place. There wouldn't be any, so this would reset the repeat count. * After that, no more need for the special-casing of ^[[3~ (DEL) introduced in f2a3f4e3. Move it to within the 'switch' block. * When handling left and right arrows and Home and End keys, do not modify cursor directly but ed_ungetchar() the corresponding traditional command keys as with the rest. Otherwise a repeat count parameter would now wrongly survive those keys. src/cmd/ksh93/sh.1: - Document control character notation used for vi mode docs. - Since vi control mode beeps and aborts on ESC except if a subsequent [ is already in the input buffer upon receiving ESC, document that VT220 escape sequences only preserve repeat counts when entered into the input buffer all at once. - Don't skip the initial ESC in the documentation of the VT220 escape sequences. In control mode, skipping the initial ESC still works as before, but that is now undocumented, as it's really nothing more than an artefact of VT220 escape processing. - Move the two long paragraphs on '-o viraw' and canonical (i.e. line-based) input processing from the vi editor introduction to the options section under 'viraw'. It is much too arcane for the intro, and besides, ksh 93u+ (and hence also 93u+m) has SHOPT_VIRAW enabled by default, so the shell is compiled to force this option on at all times, making it even less relevant for most users.		2020-09-17 19:14:39 +02:00
