note 75918 added to features.commandline

I wrote this function to parse all command-line arguments. It parses both all kinds of options (-u or -uao or --user=admin or --verbose or -p asdf and all kinds of combinations between them) and commands (like cvs update), and returns them in an array. It works both on Windows and Unix/Linux/etc. <?php /** * Parse console arguments. * * @param $args * The console argument array (usually $argv) * @param $arg_opts * An array of options which are to be followed by an argument. * This is needed to seperate these arguments of options from commands. * e.g. shell.php -u admin -v * --> $arg_opts = array('u') * @param $default_options * @return * A associative array: * $return['commands'] ia a numeric array of all commands, * $return['options'] contains the options. The option keys * are always noted without - or -- and are set to TRUE if they were * invoked, to the argument if followed by an argument, and if not present * to their default value or FALSE if no default value was specified. * * @author Franz Heinzmann (frando) < http://unbiskant.org > * @license GNU GPL Version 2 < http://www.gnu.org/licenses/gpl.txt > */ function drush_parse_args($args = array(), $arg_opts = array(), $default_options = array()) { $options = $default_options; $commands = array(); for ($i = 1; $i < count($args); $i++) { $opt = $args[$i]; // Is the arg an option (starting with '-')? if ($opt{0} == "-" && strlen($opt) != 1) { // Do we have multiple options behind one '-'? if (strlen($opt) > 2 && $opt{1} != "-") { // Each char becomes a key of its own. for ($j = 1; $j < strlen($opt); $j++) { $options[substr($opt, $j, 1)] = true; } } // Do we have a longopt (starting with '--')? elseif ($opt{1} == "-") { if ($pos = strpos($opt, '=')) { $options[substr($opt, 2, $pos - 2)] = substr($opt, $pos + 1); } else { $options[substr($opt, 2)] = true; } } else { $opt = substr($opt, 1); // Check if the current opt is in $arg_opts (= has to be followed by an argument). if ((in_array($opt, $arg_opts))) { if (($args[$i+1] == NULL) || ($args[$i+1] == "") || ($args[$i + 1]{0} == "-")) { exit("Invalid input: -$opt needs to be followed by an argument."); } $options[$opt] = $args[$i + 1]; $i++; } else { $options[$opt] = true; } } } // If it's not an option, it's a command. else { $commands[] = $opt; } } return array('options' => $options, 'commands' => $commands); } ?> ---- Server IP: 217.160.72.57 Probable Submitter: 88.64.130.33 ---- Manual Page -- http://www.php.net/manual/en/features.commandline.php Edit -- https://master.php.net/note/edit/75918 Del: integrated -- https://master.php.net/note/delete/75918/integrated Del: useless -- https://master.php.net/note/delete/75918/useless Del: bad code -- https://master.php.net/note/delete/75918/bad+code Del: spam -- https://master.php.net/note/delete/75918/spam Del: non-english -- https://master.php.net/note/delete/75918/non-english Del: in docs -- https://master.php.net/note/delete/75918/in+docs Del: other reasons-- https://master.php.net/note/delete/75918 Reject -- https://master.php.net/note/reject/75918 Search -- https://master.php.net/manage/user-notes.php
