Hi all,
within fish I'm heaviliy using drush, a shell extension for the Drupal
CMS with a lot of options that are also sometimes context sensitive.
For bash, the drush package contains a drush.complete.sh which can be
sourced for terminal sessions. That looks like this:
=================== START ============
# Completion function, uses the "drush complete" command to retrieve
# completions for a specific command line COMP_WORDS.
_drush_completion() {
# Set IFS to newline (locally), since we only use newline
separators, and
# need to retain spaces (or not) after completions.
local IFS=$'\n'
# The '< /dev/null' is a work around for a bug in php libedit stdin
handling.
# Note that libedit in place of libreadline in some distributions. See:
# https://bugs.launchpad.net/ubuntu/+source/php5/+bug/322214
COMPREPLY=( $(drush --early=includes/complete.inc "${COMP_WORDS[@]}"
< /dev/null 2> /dev/null) )
}
# Register our completion function. We include common short aliases
for Drush.
complete -o bashdefault -o default -o nospace -F _drush_completion d
dr drush drush5 drush6 drush7 drush.php
=================== FINISH ============
I'm trying to port this to fish and came as long as this:
complete -x -c drush -d "Dr" -a "(drush --early=includes/complete.inc)"
This is working to a certain extend such that it displays all options
almost all of the time. What I need is to provide the specific command
line COMP_WORDS to the script complete.inc. What is the right syntax
for that? I looked into variable expansion but could figure it out.
Once that's complete I should also define the local variable IFS=$'\n'
and I'd appreciate if anyone could give me a hint on how to get all of
this into a single command or a function for the fish shell.
Thanks in advance.
Jürgen
