# Summary: Run an executable with the selected PHP version
#
# Usage: phpenv exec <command> [arg1 arg2...]
#
# Runs an executable by first preparing PATH so that the selected PHP
# version's `bin' directory is at the front.
#
# For example, if the currently selected PHP version is 1.9.3-p327:
#   phpenv exec bundle install
#
# is equivalent to:
#   PATH="$PHPENV_ROOT/versions/1.9.3-p327/bin:$PATH" bundle install

set -e
[ -n "$PHPENV_DEBUG" ] && set -x

# Provide phpenv completions
if [ "$1" = "--complete" ]; then
  exec phpenv shims --short
