completion inside vared

completion inside vared

[-- Attachment #1: Type: text/plain, Size: 736 bytes --]

Hello, when I execute the widget _complete_help inside vared I get:

tags in context :completion::complete:-value-,a,::
    use-compctl    (_default _value _value _in_vared)
    globbed-files  (_files _default _value _value _in_vared)

I would like to modify this to only display file completion when I call
vared from a certain function, how can I do it?
I tried with:
zstyle ':completion::complete:-value-*:*' completer _files
and
zstyle ':completion::complete:*' completer _files
but
 use-compctl    (_default _value _value _in_vared)
is still there, and I get various completion suggestion that aren't files
(or folders) in the current directory, such as environment variable names,
executable names, etc

thanks

Been busy and didn't have a chance to respond before.

The _in_vared completer forces use of _value which calls _default.  A
side-effect of _default is that compctl completions are attempted.

So what you need is:
zstyle ':completion::complete:-value-*:*' use-compctl no

Or if you want it to be specific to vared, something like:
zstyle -e ':completion::complete:-value-*:*' use-compctl '[[
$funcstack = *_in_vared* ]] && reply=no'

which admittedly is a bit convoluted ... _in_vared probably ought to
be doing some style checks of its own rather than pushing everything
down to _value.

yes that worked (apart from a space to be added between [[and $ funcstack),
thanks.
I'm having another annoyance:
when I exit with ctrl-c from

vared -ehp $prompt text

the history file gets emptied. I tried
trap 'zle send-break' INT
but it doesn't change the result

Is there something I can do to exit from vared with a key combination
(ctrl-d only works if the line is empty) without losing the history?
I could use zle to send the kill-whole-line widget, but how do I send
ctrl-d then? Is it possibile with zle to send key combinations?

thanks

Something to do with gmail line wrapping/unwrapping, sorry.

Which history is getting lost?  The global shell history i.e. $HISTFILE?

Have you tried exiting vared with ctrl-g ?  Does that have the same problem?

no, before invoking vared I do

fc -p -a $file 200 200

to have an history specific for the command

I just found out that replacing my previous trap with
trap 'return 1' INT

the history file is preserved after a ctrl-c.
If I instead do ctrl-g (send-break) the history file gets "cleaned" again
by cleaned I mean not really empty, but a file that contains just the first
row of the history, for example
if the history file contained:

: 1645479991:0;./Desktop/
: 1645480234:0;./Mail/
: 1645480247:0;./nltk_data/

and I enter vared, than send ctrl-g, the file contains then only

: 1645479991:0;./Desktop/

Is it possible to catch send-break? is it implemented through a trappable
signal?

thanks

I will try to bump up this question once more, since I am stuck on this

tldr: I would like to be able to use the send-break zle widget inside vared
to exit it, but when I do, the history file is cropped to one line.
Initially I had the same problem with ctrl-c, but I found out that a
trap 'return 1' INT
is able to prevent the behaviour in that case

thanks for any further help
