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
--------------------

```php
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 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'
]);
}

public function execute($user,$repo) {
$this->logger->notice('executing bar command.');
$this->logger->info('info message');
$this->logger->debug('info message');
$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
}
}
```

See documentation on our 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

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

Zsh Completion Generator
----------------------------

```sh
example/demo zsh demo > _demo
source _demo
```

```sh
demo
```

Console Prompt (Readline)
-------------------------

simple prompt:

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

$ php demo.php
Your name please:

prompt and except valid values:

```php
$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:

```php
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
----------------------

```php
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
--------------------

```php
$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
-----------------

```php
$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

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

### ConsoleDebug class

```php
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.

6. Send a pull request.

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.
