(:a) specifier for not existent files

(:a) specifier for not existent files

[Stefan Reichör]

Hi,

I am using the (:a) specifier to get absoulte file paths. But this works
only for existing files. Is there a way to make it work for not existing
files also?

These are some experiments:

% echo .(:a)
/home/stefan/work
% echo tgz(:a)
/home/stefan/work/tgz
% echo tgz2(:a)
zsh: no matches found: tgz2(:a)


And here is the function that uses the above feature:

function ec
{
    emacsclient --no-wait $1(:a)
}


It would be nice to allow the creation of not existing files in emacsclient...


Thanks,
  Stefan.

Not in general, because it can't sanity check the path so it doesn't
know what to do to it.  But you can handle some simple cases:

if [[ ! -e $1 ]]; then
  local dir=${1:h}
  if [[ -d $dir ]]; then
    dir=(${dir}(:a))
    1=${dir[1]}/${1:t}
  fi
fi

This works for names without a slash since ${1:h} returns ".".
