Some drupal drush commands used as experiments aimed at creating pipes for glup? I dunno. We'll see.

drush-experiments1.sh

# simple drupal calls via drush 
drush @d7Test ev '$a = node_type_get_types(); while (list($k,$v) = each($a)) {echo "\"$k\",\"$v->name\",\"$v->description\"\n\n";}'

drush @d7Test ev '$a = system_get_info("theme"); while (list($k,$v) = each($a)) {echo "\"$k\",\"$v->name\",\"$v->description\"\n\n";}'

#unions might be nice?
drush @d7Test ev '$a = system_get_info("module"); while (list($k,$v) = each($a)) {echo "\"$k\",\"$v->name\",\"$v->description\"\n\n";}'

drush @slndev ev '$a = array_keys(system_get_info("theme")); while (list($k,$v) = each($a)) {echo "$k\n";}'

# dump a return value
drush @slndev ev '$a = system_get_info("theme"); while (list($k,$v) = each($a)) {echo var_export($a, 1) . "\n\n";}'

# display first item in array
drush @slndev ev '$a = array_shift(system_get_info("theme")); {echo var_export($a,1) . "\n";}'

#display top level keys based on first item in array
drush @slndev ev '$a = array_keys(array_shift(system_get_info("theme"))); while (list($k,$v) = each($a)) {echo "$v\n";}'

# how check for null before array_keys call? - this throws an error
drush @slndev ev '$a = array_keys(array_shift(system_get_info("modules"))); while (list($k,$v) = each($a)) {echo "$v\n";}'

# active themes
drush @slndev ev '$a = array_shift(system_get_info("theme")); {echo $a["name"] . "\n\n";}'

# show theme regions
drush @slndev ev '$a = system_get_info("theme"); while (list($k,$v) = each($a)) {echo $k . ": " .  var_export($v["regions"], 1) . "\n\n";}'
