CLIFramework

CLIFramework is a command-line application framework, for building flexiable, simple command-line applications.

Commands and Subcommands can be registered from outside of an application or your plugins.

Defining a new command is pretty simple, all you need to is declare a class which is inherited from CLIFramework\Command class.

Features

• Intuitive command class and option spec

• command options are supported, powered by GetOptionKit. including long option, short option, required|optional|default value.

• Hierarchical commands.

• Automatic help page generation.

• Automatic zsh completion generator.

• Automatic bash completion generator.

• Friendly message when command arguments are not enough.

• Testable, CLIFramework provides PHPUnit test case for testing the commands in PHP.

• Argument validation, suggestion,

• Command Groups

• HHVM compatible

Synopsis

class CommitCommand extends CLIFramework\Command {

    public function brief() { return 'brief of bar'; }

    public function options($opts) {
        $opts->add('C|reuse-message:','Take an existing commit object, and reuse the log message and the authorship information (including the timestamp) when creating the commit.')
            ->isa('string')
            ->valueName('commit hash')
            // ->validValues([ 'static-50768ab', 'static-c2efdc2', 'static-ed5ba6a', 'static-cf0b1eb'])
            ->validValues(function() {
                $output = array();
                exec("git rev-list --abbrev-commit HEAD -n 20", $output);
                return $output;
            })
            ;

        // Runtime completion by setting up a closure for completion
        $opts->add('c|reedit-message:','like -C, but with -c the editor is invoked, so that the user can further edit the commit message.')
            ->isa('string')
            ->valueName('commit hash')
            ->validValues(function() {
                // exec("git log -n 10 --pretty=format:%H:%s", $output);
                exec("git log -n 10 --pretty=format:%H:%s", $output);
                return array_map(function($line) {
                    list($key,$val) = explode(':',$line);
                    $val = preg_replace('/\W/',' ', $val);
                    return array($key, $val);
                }, $output);
            })
            ;

        $opts->add('author:', 'Override the commit author. Specify an explicit author using the standard A U Thor <[email protected]> format.')
            ->suggestions(array( 'c9s', 'foo' , 'bar' ))
            ->valueName('author name')
            ;

        $opts->add('output:', 'Output file')
            ->isa('file')
            ;

    public function arguments($args) {
        $args->add('user')
            ->validValues(['c9s','bar','foo']);

        // Static completion result
        $args->add('repo')
            ->validValues(['CLIFramework','GetOptionKit']);

        // Add an argument info expecting multiple *.php files
        $args->add('file')
            ->isa('file')
            ->glob('*.php')
            ->multiple()
            ;
    }

    public function init() {

        $this->command('foo'); // register App\Command\FooCommand automatically

        $this->command('bar', 'WhatEver\MyCommand\BarCommand');

        $this->commandGroup('General Commands', ['foo', 'bar']);

        $this->commandGroup('Database Commands', ['create-db', 'drop-db']);

        $this->commandGroup('More Commands', [
            'foo' => 'WhatEver\MyCommand\FooCommand',
            'bar' => 'WhatEver\MyCommand\BarCommand'
        ]);

        $this->logger->write('just write');
        $this->logger->writeln('just drop a line');
        $this->logger->newline();

        return "Return result as an API"; // This can be integrated in your web application
    }
}

Automatic Zsh Completion Generator

Zsh Completion With Lazy Completion Values:

Bash Completion

Documentation

See documentation on our wiki https://github.com/c9s/CLIFramework/wiki

Command Forms

CLIFramework supports many command-line forms, for example:

$ app [app-opts] [subcommand1] [subcommand1-opts] [subcommand2] [subcommand2-opts] .... [arguments] 

If the subcommand is not defined, you can still use the simple form:

$ app [app-opts] [arguments]

For example,

$ app db schema --clean dbname
$ app gen controller --opt1 --opt2 ControllerName 

Subcommand Hierarchy

Commands have methods for stages, like prepare, execute, finish, for a command like below:

$ app foo_cmd bar_cmd arg1 arg2 arg3

The call graph is like:

app->run
- app->prepare
  - foo_cmd->prepare
    - bar_cmd->prepare
    - bar_cmd->execute
    - bar_cmd->finish
  - foo_cmd->finish
- app->finish

Basic Requirement

• PHP 5.3

Installation

From composer

{
    "require": {
        "corneltek/cliframework": "*"
    }
}

Zsh Completion Generator

example/demo zsh demo > _demo
source _demo

demo <TAB>

Console Prompt (Readline)

simple prompt:

$input = $this->ask("Your name please");

$ php demo.php
Your name please: 

prompt and except valid values:

$input = $this->ask("Your name please", array('John', 'Pedro'));

Version Info

CLIFrameword has a built-in --version option, to setup the version info, you can simply override a const in your application class to setup version string:

class ConsoleApp extends CLIFramework\Application
{
    const NAME = 'YourApp';
    const VERSION = '1.2.1';
}

This shows:

$ yourapp.php --version
YourApp - version 1.2.1

Example

Please check example/demo.php

$ php example/demo.php

ArgumentEditor

use CLIFramework\ArgumentEditor\ArgumentEditor;

$editor = new ArgumentEditor(array('./configure','--enable-debug'));
$editor->append('--enable-zip');
$editor->append('--with-sqlite','--with-postgres');

echo $editor;
# ./configure --enable-debug --enable-zip --with-sqlite --with-postgres

Message style formatter

$formatter = new CLIFramework\Formatter;
$formatter->format( 'message' , 'green' );

Built-in styles:

'red'          => array('fg' => 'red'),
'green'        => array('fg' => 'green'),
'white'        => array('fg' => 'white'),
'yellow'       => array('fg' => 'yellow'),
'strong_red'   => array('fg' => 'red', 'bold'  => 1),
'strong_green' => array('fg' => 'green','bold' => 1),
'strong_white' => array('fg' => 'white','bold' => 1),

Building Phar Archive file

COMPOSER=tests/fixture/composer.json.phar-test composer install
php example/demo archive --working-dir /Users/c9s/work/php/CLIFramework \
        --composer tests/fixture/composer.json.phar-test \
        app.phar

Chooser Component

$chooser = new CLIFramework\Chooser;
$value = $chooser->choose( "System Options" , array( 
    'use php-5.4.0' => '5.4.0',
    'use php-5.4.1' => '5.4.1',
    'use system' => '5.3.0',
));

Debug Utilities

LineIndicator

use CLIFramework\Debug\LineIndicator;
$indicator = new LineIndicator;
echo PHP_EOL, $indicator->indicateFile(__FILE__, __LINE__);

ConsoleDebug class

use CLIFramework\Debug\ConsoleDebug;

ConsoleDebug::dumpRows($pdo->fetchAll());

ConsoleDebug::dumpException($e);

Todos in the next release

• [ ] provide a easy way to define chained commands
• [ ] inheritable options for subcommands.
• [ ] human readable exception renderer.
• [ ] interact utilities

Hacking

Setup

1. Download & install Onion from https://github.com/phpbrew/Onion

2. Use Onion to bundle the dependencies:

   $ onion bundle

3. Run tests, it should pass.

4. Hack hack hack.

5. Run tests.

How command class register works

• CLIApplication is inherited from CommandBase.
• Command is also inherited from CommandBase.
• To register a subcommand, we use the addCommand method to register commands or subcommands.
  • The command class is optional, if command class name is omitted, then the addCommand method will try to guess the real command class, and try to load the command class.
