Looking for a pointer on what to search for to find information on command expansion / substitution.

Looking for a pointer on what to search for to find information on command expansion / substitution.

Hi,

I need some help knowing what to search for / where to look to find 
information on something I want to rebuild after recently loosing access 
to a system with a working config.  (Please don't ask, I can't tell.)

I had a Zsh feature configured such that I could type "sclient<space>" 
and it ZLE (?) would replace that with "openssl s_client".

I'd like to rebuild this functionality on my current system, but I'm not 
sure what Zsh feature this was.  I do know that it wasn't aliase.  I 
also think that it wasn't a function.  I /think/ it was a ZLE tweak.

Will someone point me at what I need to search for in the man page to 
rebuild this functionality?

My best guess is that you had the following snippet in .zshrc that
you'd copied from zshwiki.org:

    typeset -gA abbreviations=(
      'sclient' 'openssl s_client'
    )

    magic-abbrev-expand() {
        emulate -L zsh -o extended_glob
        local MATCH
        LBUFFER="${LBUFFER%%(#m)[_a-zA-Z0-9]#}"
        LBUFFER+="${abbreviations[$MATCH]:-$MATCH}"
        zle self-insert
    }

    no-magic-abbrev-expand() {
        LBUFFER+=' '
    }

    zle -N magic-abbrev-expand
    zle -N no-magic-abbrev-expand
    bindkey ' ' magic-abbrev-expand
    bindkey '^x ' no-magic-abbrev-expand

Thank you Roman.  That does seem to function the way that -- I think -- 
I want.

The magic-abbrev-expand() function seems to be more complex than I 
remember.  But perhaps I'm mis-remembering and / or this version is more 
robust than what I was using.

Either way, this does provide the desired functionality.

I will use this as is for now and spend more time learning about the 
components in the coming days.

Thank you again.  :-)

This is exactly the same message you posted two days ago.  Did you
resend it erroneously?  Did you see Roman's reply to the original?

Looks like some kind of email delivery mishap. See below:

I didn't /personally/ re-send it.  But -- as Roman indicated -- it seems 
as if there was some sort of yet unexplained email communications error 
that caused the message to be duplicated - now triplicated.

I've never seen this type of failure before.

There seems to have been a transient routing problem that was causing havoc.

My mail server doesn't think that the message was successfully delivered 
until just a little bit ago.  It's been trying to communicate with 
mail.zsh.org for days but couldn't because of routing problems.

Yes I did.

As evident by my reply to Roman thanking him.

Which wasn't delivered to the list until two hours ago.

I wanted to provide some follow up on some minor tweaks that I've made 
to be compatible with an older version of Zsh; 4.3.10.

I have changed the following:

     typeset -gA abbreviations=(
       'sclient' 'openssl s_client'
     )

To be:

     typeset -gA abbreviations
     typeset abbreviations=(
       'sclient' 'openssl s_client'
     )

I have also remarked the following:

     emulate -L zsh -o extended_glob

I am indeed getting the desired functionality, even on older versions of 
Zsh.

Thank you again Roman for pointing to the documentation and for the 
solution.
