Do I fail? You probably *should* be able to do this: zle -A vicmd main Unfortunately, if you do that, although the shell starts in vicmd mode, you can't get into viins mode, because the code which implements `vi-insert' switches to the main keymap, i.e. in this case straight back to vicmd. This is actually documented, but I'm not sure if it's necessary. You can get round it with: vi-insert() { zle -K viins; } zle -N vi-insert but unfortunately you need to rewrite every widget that switches to insert mode (those bound to I, a, A, c, etc. etc.) in a similar fashion. What does everyone think about tying vi-insert to switching to viins, rather than `main' (and other logically related changes)? This would need changes in the documentation, too. Note there's nothing to stop you copying another keymap onto viins, so I don't think this stops you doing anything you might want to. I think the problem comes with the vi-cmd-mode binding in Emacs mode. In this case, `i' or whatever will put you into vi insert mode, not back to Emacs mode. But that seems to me to be exactly what is documented: vi-insert (unbound) (i) (unbound) Enter insert mode. --- nothing about returning to the main keymap. You can write a widget to switch the keymap. main-map() { zle -K main; } zle -N main-map bindkey -M vicmd 'M' main-map then i etc. still do what are documented, but 'M' returns you to the main keymap. This seems to me more useful and predictable than the current arrangement. If there's deathly silence I won't dare change this.

I believe the intent was that in Emacs mode one could switch to vi command mode and then switch back to Emacs mode by invoking an insert command from the vicmd keymap. That is, one can have vi-style modal editing with the insert mode keymap actually being Emacs mode. Changing the vi insert commands to switch to the "viins" keymap would make this impossible in the current keymap arrangement. It would still be possible to get a similar effect by making "viins" an alias for the "emacs" keymap, but this is an extra setup step and comes at the expense of the real vi insert mode keymap. I suggest that to achieve starting editing in vi command mode what one wants to do is select the "vicmd" keymap instead of "main" when the editor is invoked. Perhaps there could be a specially-named widget that, if it exists, gets invoked as soon as ZLE has started up to start editing a new command line; this would be the in-ZLE equivalent of the precmd function. -zefram ^ permalink raw reply [flat|nested] 4+ messages in thread

I'm sure that's correct, but it's undocumented and to mind confusing. Further, I suspect few people use vicmd from Emacs at all. So I thought the new way would be more useful. > I suggest that to achieve starting editing in vi command mode what one > wants to do is select the "vicmd" keymap instead of "main" when the editor > is invoked.

That would be useful anyway. We could have zle-init-hook (at initialisation) and zle-start-hook (each time the editor is started). -- Peter Stephenson <pws@csr.com> Software Engineer CSR Ltd., Science Park, Milton Road, Cambridge, CB4 0WH, UK Tel: +44 (0)1223 692070 ********************************************************************** The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
