Even the existence of a PHP call in a bash_completion.d script or any
referenced Bash script may cause a complete completion failure, even
when all STDERR and STDOUT output is suppressed (redirected to
/dev/null), depending on what row it's effectively referenced from in
the top-most bash_completion.d script. From what little material there
is about this on the Internet, it appears that this problem might be a
result of particular Ubuntu versions. No matter.
Bash completion with PHP works fine when used with the CGI variant. For
example:
> /etc/bash_completion.d/foo
(Extends example at
http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_2)
============================
_foo()
{
local cur opts
COMPREPLY=()
cur="${COMP_WORDS[COMP_CWORD]}"
SAVE_IFS=$IFS
IFS=","
BUFFER="${COMP_WORDS[*]}"
IFS=$SAVE_IFS
opts=echo "$COMP_CWORD:$BUFFER" | /tmp/completiontest.php
if [[ ${cur} == -* ]] ; then
COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
return 0
fi
}
complete -F _foo foo
> /tmp/completiontest.php
=========================
#!/usr/bin/php5-cgi -q
<?php
// Just to 1) prevent writing to the bash_completion.d directory, and
// 2) nail-down where our output file, below, will end up.
chdir(dirname(__FILE__));
// Grab completion information from STDIN.
// Ex:
// dustin@mx4:~$ foo --arg1 --arg2 --to_be_complet<TAB>^C
// dustin@mx4:~$ cat /tmp/stdin.txt
// 3:foo,--arg1,--arg2,--to_be_complet
//
// Format of received STDIN information is "<number of
tokens>:<comma-sep list of tokens>"
file_put_contents('stdin.txt', file_get_contents('php://stdin'));
// Output the space-separated completion possibilities.
print("--abc --def");

Description:
------------
Calling PHP shell-scripts in any way (even if it doesn't do anything)
from a bash-completion script causes the bash-completion script to fail
(pressing TAB causes erratic spacing and tabbing at the console rather
than producing options for completion). Bash and Perl calls work fine.
This refers to calling PHP in any of the following ways:
o php -r '..'
o php script.php
o ./script.php (this references '/usr/bin/php' with a shebang at the
top)
I even tried calling Perl from the Bash, and then calling PHP from the
Perl. No change in behavior. I tried with both 5.2 and the latest
version of 5.3 .
Test script:
---------------
No test script necessary. Executing "php -r ''" in a bash completion
script causes the failure.
Contents of ~/completiontest can be found at:
http://www.randomingenuity.com/phpbugreference/20101010-2054_completiontest.php
You can commit this to the current bash-completion configuration by
executing:
~$ . completiontest
To test without PHP, just comment-out the PHP call.
Expected result:
----------------
dustin@ubuntu:~$ . completiontest
dustin@ubuntu:~$ completiontest --<TAB><TAB>
--help --verbose --version
dustin@ubuntu:~$ completiontest --
Actual result:
--------------
dustin@ubuntu:~$ . completiontest
dustin@ubuntu:~$ completiontest -- |<-- Cursor moves to here.
