vi-mode: editor function

vi-mode: editor function

[Sepp Tannhuber]

Dear all,

I have written a theme for the oh-my-zsh prompt from robbyrussel because I was 
sometimes confused about the different vi modes. My prompt shows, at a glance,
which vi mode is active, similar to the vim airline plugin.

For the indicators, the theme uses functions like the following:
    vi-insert() {
      MODE="INSERT"                                                                                                           
      builtin zle .vi-insert
    }   
    zle -N vi-insert
    bindkey -M vicmd "i" vi-insert

    vi-replace() {
      MODE="REPLACE"
      builtin zle .vi-replace
    }   
    zle -N vi-replace
    bindkey -M vicmd "R" vi-replace

The MODE variable finally sets the indicator for the prompt.
This works very well, except in the following case. When I call the editor with
    [ESC] [v] 
I can edit the command line with vi, as expected. But after closing the editor,
the zsh prompt is in INSERT mode. It has been in NORMAL mode before. And this is
not considered in my script. Thus, I would like to know, whether there is a
function, equivalent to the ones above. I am looking for something like this:
    vi-editor() {
      MODE="INSERT"                    # prompt is in INSERT mode after editing
      builtin zle .vi-editor
    }   
    zle -N vi-editor
    bindkey -M vicmd "v" vi-editor

Unfortunately I could not find something like vi-editor it in the zshzle manual.
Has anybody an idea what I can use instead? Or what is the default vicmd for [v]?

Best regards
Joseph

There is no default binding for v in vicmd mode, so you are encountering
something installed for you by oh-my-zsh.  Most likely it is the user-
contributed edit-command-line widget (man zshcontrib).

If oh-my-zsh hasn't already pre-empted the zle-line-init, zle-line-finish,
and zle-keymap-select widgets, you might find it more effective to set the
MODE variable with those, rather than trying to override all the individual
widgets that might change mode.

Dear Bart,

thank you for the hint. Indeed, I found an edit-command-line module in zshcontrib.
And yes, it is loaded by oh-my-zsh. So I could fix my theme script.

Unfortunately, I have no idea how to set the MODE variable the way you mentioned.
If anybody wants to tell me, you can find the script at 
  https://github.com/tannhuber/oh-my-zsh/blob/master/themes/budspencer.zsh-theme
But don't waste your time. Everything is working well, now.

Thank you
Joseph

FWIW, you could simplify your builtin redefinitions by using the ZLE_STATE
variable.

Changes from 4.3.11:
The parameter ZLE_STATE, available in user-defined line editor widgets,
gives information on the state of the line editor.  Currently this is
whether the line editor is in insert or overwrite mode.

Dear Julien,

I didn't know the ZLE_STATE variable before. There's also the KEYMAP variable with the two modes "main" and "vicmd". The combination of both variables does the trick. It seems a little bit weird that both variables cannot show all three modes correctly.

Thank you very much
Joseph
