do not add a space after completion

do not add a space after completion

[Eric Smith]

I have a completion function that when executed should supply
no extra space after the option is given (on pressing <tab>).

Ideally it should append an underscore instead.

How would I achieve that (just for this function and not globally)?

thanks.

When calling compadd, pass the -S option and possibly the -r option.
There is a partial example under the -r option description in the
manual.  For your specific case, probably you want:

    compadd -S _ -r '_ \t\n' ...

(replacing "..." with other options and potential matches, etc.)

invoking compadd so that completion is for the second argument

[Eric Smith]

I want to set up completion rules for the second argument
and not the first which appears to eb the default.

How would i do this?

Thanks

Could you provide an example command line to illustrate what you
intend to have happen?

For example, given a command line such as:

% roger dodger codger

Do you mean:

(1) The completion for "roger" is invoked, but the set of matches for
    "codger" is not the same as the set of matches for "dodger"; or

(2) The completion for "dodger" should be invoked (as if "roger" were
    not present) in order to generate matches for "codger"; or

(3) Some other thing entirely.

If (1), the best answer may be different if the matches for "codger"
are purely based on its position on the command line, or if they may
depend on what appears as the word in the "dodger" position.

Thanks Bart

Something like this, indeed.

I create commands that allow me to copy or move existing files to
special named files.  The prefix of these special names I want
to look up from a list in a file referenced by compadd.

So the command:
% prefix_cp sour<tab>
will just complete as per the default rules, but

% prefix_cp source_file.pdf <tab>
should give me:
% prefix_cp source_file.pdf aa_code_reference_00034
assuming this was the first match in the list

<parenthesis>
Oh I just had an idea for the first time now writing this.
If I went:
% prefix_cp source_file.pdf aa_code_reference_00034_<tab>
It would be great to have as the completion the first arg viz.
!#1 or `source_file.pdf'

But this is a bonus.

</parenthesis>

Thanks a lot.

Eric

You want something like:


#compdef prefix_cp

if (( CURRENT == 2 )); then
  _default
else
  local expl
  local -a array
  array=(special1 special2)
  _wanted special expl 'special value' compadd -a array
fi
