It can be triggered manually with $command->showHelp()
or automatic when -h
or --help
option is passed to $command->parse()
.
For above example, the output would be:
It can be triggered manually with $command->showVersion()
or automatic when -V
or --version
option is passed to $command->parse()
.
For above example, the output would be:
0.0.1-dev
Definitely check adhocore/phint - a real world console application made using adhocore/cli
.
Here we simulate a git
app with limited functionality of add
, and checkout
.
You will see how intuitive, fluent and cheese building a console app is!
$app = new Ahc\Cli\Application('git', '0.0.1');
$app
// Register `add` command
->command('add', 'Stage changed files', 'a') // alias a
// Set options and arguments for this command
->arguments('<path> [paths...]')
->option('-f --force', 'Force add ignored file', 'boolval', false)
->option('-N --intent-to-add', 'Add content later but index now', 'boolval', false)
// Handler for this command: param names should match but order can be anything :)
->action(function ($path, $paths, $force, $intentToAdd) {
array_unshift($paths, $path);
echo ($intentToAdd ? 'Intent to add ' : 'Add ')
. implode(', ', $paths)
. ($force ? ' with force' : '');
// If you return integer from here, that will be taken as exit error code
})
// Done setting up this command for now, tap() to retreat back so we can add another command
->tap()
->command('checkout', 'Switch branches', 'co') // alias co
->arguments('<branch>')
->option('-b --new-branch', 'Create a new branch and switch to it', false)
->option('-f --force', 'Checkout even if index differs', 'boolval', false)
->action(function ($branch, $newBranch, $force) {
echo 'Checkout to '
. ($newBranch ? 'new ' . $branch : $branch)
. ($force ? ' with force' : '');
})
;
// Parse only parses input but doesnt invoke action
$app->parse(['git', 'add', 'path1', 'path2', 'path3', '-f']);
// Handle will do both parse and invoke action.
$app->handle(['git', 'add', 'path1', 'path2', 'path3', '-f']);
// Will produce: Add path1, path2, path3 with force
$app->handle(['git', 'co', '-b', 'master-2', '-f']);
// Will produce: Checkout to new master-2 with force
Instead of inline commands/actions, we define and add our own commands (having interact()
and execute()
) to the app:
class InitCommand extends Ahc\Cli\Input\Command
{
public function __construct()
{
parent::__construct('init', 'Init something');
$help = '<cyan>Custom help screen</end>';
$writer = new Ahc\Cli\Output\Writer();
$this
->argument('<arrg>', 'The Arrg')
->argument('[arg2]', 'The Arg2')
->option('-a --apple', 'The Apple')
->option('-b --ball', 'The ball')
->help($writer->colorizer()->colors($help))
// Usage examples:
->usage(
// append details or explanation of given example with ` ## ` so they will be uniformly aligned when shown
'<bold> init</end> <comment>--apple applet --ball ballon <arggg></end> ## details 1<eol/>' .
// $0 will be interpolated to actual command name
'<bold> $0</end> <comment>-a applet -b ballon <arggg> [arg2]</end> ## details 2<eol/>'
)
->logo('Ascii art logo of your command');
}
// This method is auto called before `self::execute()` and receives `Interactor $io` instance
public function interact(Ahc\Cli\IO\Interactor $io) : void
{
// Collect missing opts/args
if (!$this->apple) {
$this->set('apple', $io->prompt('Enter apple'));
}
if (!$this->ball) {
$this->set('ball', $io->prompt('Enter ball'));
}
// ...
}
// When app->handle() locates `init` command it automatically calls `execute()`
// with correct $ball and $apple values
public function execute($ball, $apple)
{
$io = $this->app()->io();
$io->write('Apple ' . $apple, true);
$io->write('Ball ' . $ball, true);
// more codes ...
// If you return integer from here, that will be taken as exit error code
}
}
class OtherCommand extends Ahc\Cli\Input\Command
{
public function __construct()
{
parent::__construct('other', 'Other something');
}
public function execute()
{
$io = $this->app()->io();
$io->write('Other command');
// more codes ...
// If you return integer from here, that will be taken as exit error code
}
}
// Init App with name and version
$app = new Ahc\Cli\Application('App', 'v0.0.1');
// Add commands with optional aliases`
$app->add(new InitCommand, 'i');
$app->add(new OtherCommand, 'o');
// Set logo
$app->logo('Ascii art logo of your app');
// Custom help screen
$app->help('Custom help screen (if omitted one will be generated)');
$app->handle($_SERVER['argv']); // if argv[1] is `i` or `init` it executes InitCommand
Grouped commands are listed together in commands list. Explicit grouping a command is optional.
By default if a command name has a colon :
then the part before it is taken as a group,
else *
is taken as a group.
Example: command name
app:env
has a default groupapp
, command nameappenv
has group*
.
// Add grouped commands:
$app->group('Configuration', function ($app) {
$app->add(new ConfigSetCommand);
$app->add(new ConfigListCommand);
});
// Alternatively, set group one by one in each commands:
$app->add((new ConfigSetCommand)->inGroup('Config'));
$app->add((new ConfigListCommand)->inGroup('Config'));
...
By default, running your CLI app without any arguments will show the help screen. However you can set the default action to run one of your commands either by setting the third parameter of the add
function to true
or by using the defaultCommand
function.
$app->add(new InitCommand, 'i', true);
// Alternatively
$app->command('init', 'Init something', 'i');
$app->defaultCommand('init');
// Retrieve the name of the default command
$default_command = $app->getDefaultCommand();
Set a custom exception handler as callback. The callback receives exception & exit code. The callback may rethrow exception or may exit the program or just log exception and do nothing else.
$app = new Ahc\Cli\Application('App', 'v0.0.1');
$app->add(...);
$app->onException(function (Throwable $e, int $exitCode) {
// send to sentry
// write to logs
// optionally, exit with exit code:
exit($exitCode);
// or optionally rethrow, a rethrown exception is propagated to top layer caller.
throw $e;
})->handle($argv);
It can be triggered manually with $app->showHelp()
or automatic when -h
or --help
option is passed to $app->parse()
.
Note If you pass something like ['app', cmd', '-h']
to $app->parse()
it will automatically and instantly show you help of that cmd
and not the $app
.
For above example, the output would be:
Same version number is passed to all attached Commands. So you can trigger version on any of the commands.
Very thin shell wrapper that provides convenience methods around proc_open()
.
$shell = new Ahc\Cli\Helper\Shell($command = 'php -v', $rawInput = null);
// Waits until proc finishes
$shell->execute($async = false); // default false
echo $shell->getOutput(); // PHP version string (often with zend/opcache info)
$shell = new Ahc\Cli\Helper\Shell('php /some/long/running/scipt.php');
// With async flag, doesnt wait for proc to finish!
$shell->setOptions($workDir = '/home', $envVars = [])
->execute($async = true)
->isRunning(); // true
// Force stop anytime (please check php.net/proc_close)
$shell->stop(); // also closes pipes
// Force kill anytime (please check php.net/proc_terminate)
$shell->kill();
$shell = new Ahc\Cli\Helper\Shell('php /some/long/running/scipt.php');
// Wait for at most 10.5 seconds for proc to finish!
// If it doesnt complete by then, throws exception
$shell->setOptions($workDir, $envVars, $timeout = 10.5)->execute();
// And if it completes within timeout, you can access the stdout/stderr
echo $shell->getOutput();
echo $shell->getErrorOutput();
You can perform user interaction like printing colored output, reading user input programatically and moving the cursors around with provided Ahc\Cli\IO\Interactor
.
$interactor = new Ahc\Cli\IO\Interactor;
// For mocking io:
$interactor = new Ahc\Cli\IO\Interactor($inputPath, $outputPath);
$confirm = $interactor->confirm('Are you happy?', 'n'); // Default: n (no)
$confirm // is a boolean
? $interactor->greenBold('You are happy :)', true) // Output green bold text
: $interactor->redBold('You are sad :(', true); // Output red bold text
$fruits = ['a' => 'apple', 'b' => 'banana'];
$choice = $interactor->choice('Select a fruit', $fruits, 'b');
$interactor->greenBold("You selected: {$fruits[$choice]}", true);
$fruits = ['a' => 'apple', 'b' => 'banana', 'c' => 'cherry'];
$choices = $interactor->choices('Select fruit(s)', $fruits, ['b', 'c']);
$choices = \array_map(function ($c) use ($fruits) { return $fruits[$c]; }, $choices);
$interactor->greenBold('You selected: ' . implode(', ', $choices), true);
$any = $interactor->prompt('Anything', rand(1, 100)); // Random default
$interactor->greenBold("Anything is: $any", true);
$nameValidator = function ($value) {
if (\strlen($value) < 5) {
throw new \InvalidArgumentException('Name should be atleast 5 chars');
}
return $value;
};
// No default, Retry 5 more times
$name = $interactor->prompt('Name', null, $nameValidator, 5);
$interactor->greenBold("The name is: $name", true);
Prompt hidden
On windows platform, it may change the fontface which can be fixed.
$passValidator = function ($pass) {
if (\strlen($pass) < 6) {
throw new \InvalidArgumentException('Password too short');
}
return $pass;
};
$pass = $interactor->promptHidden('Password', $passValidator, 2);
The interactor is composed of Ahc\Cli\Input\Reader
and Ahc\Cli\Output\Writer
while the Writer
itself is composed of Ahc\Cli\Output\Color
. All these components can be used standalone.
Color looks cool!
$color = new Ahc\Cli\Output\Color;
echo $color->warn('This is warning');
echo $color->info('This is info');
echo $color->error('This is error');
echo $color->comment('This is comment');
echo $color->ok('This is ok msg');
Ahc\Cli\Output\Color::style('mystyle', [
'bg' => Ahc\Cli\Output\Color::CYAN,
'fg' => Ahc\Cli\Output\Color::fg256(57), // 256 colors can be used as well
'bold' => 1, // You can experiment with 0, 1, 2, 3 ... as well
]);
echo $color->mystyle('My text');
There are a number of pre-defined built-in styles that allows you granular customization to different output conditions such as help and prompts:
- answer
- choice
- comment
- error
- help_category
- help_description_even
- help_description_odd
- help_example
- help_footer
- help_group
- help_header
- help_item_even
- help_item_odd
- help_summary
- help_text
- info
- logo
- ok
- question
- version
- warn
Overriding a built-in style works the same way as defining a new style:
Ahc\Cli\Output\Color::style('error', [
'fg' => Ahc\Cli\Output\Color::RED,
'bold' => 1,
]);
Move cursor around, erase line up or down, clear screen.
$cursor = new Ahc\Cli\Output\Cursor;
echo $cursor->up(1)
. $cursor->down(2)
. $cursor->right(3)
. $cursor->left(4)
. $cursor->next(0)
. $cursor->prev(2);
. $cursor->eraseLine()
. $cursor->clear()
. $cursor->clearUp()
. $cursor->clearDown()
. $cursor->moveTo(5, 8); // x, y
Easily add a progress bar to your output:
$progress = new Ahc\Cli\Output\ProgressBar(100);
for ($i = 0; $i <= 100; $i++) {
$progress->current($i);
// Simulate something happening
usleep(80000);
}
You can also manually advance the bar:
$progress = new Ahc\Cli\Output\ProgressBar(100);
// Do something
$progress->advance(); // Adds 1 to the current progress
// Do something
$progress->advance(10); // Adds 10 to the current progress
// Do something
$progress->advance(5, 'Still going.'); // Adds 5, displays a label
You can override the progress bar options to customize it to your liking:
$progress = new Ahc\Cli\Output\ProgressBar(100);
$progress->option('pointer', '>>');
$progress->option('loader', '▩');
// You can set the progress fluently
$progress->option('pointer', '>>')->option('loader', '▩');
// You can also use an associative array to set many options in one time
$progress->option([
'pointer' => '>>',
'loader' => '▩'
]);
// Available options
+---------------+------------------------------------------------------+---------------+
| Option | Description | Default value |
+===============+======================================================+===============+
| pointer | The progress bar head symbol | > |
| loader | The loader symbol | = |
| color | The color of progress bar | white |
| labelColor | The text color of the label | white |
| labelPosition | The position of the label (top, bottom, left, right) | bottom |
+---------------+------------------------------------------------------+---------------+
Write anything in style.
$writer = new Ahc\Cli\Output\Writer;
// All writes are forwarded to STDOUT
// But if you specify error, then to STDERR
$writer->errorBold('This is error');
You can call methods composed of any combinations:
'<colorName>', 'bold', 'bg', 'fg', 'warn', 'info', 'error', 'ok', 'comment'
... in any order (eg: bgRedFgBlaock
, boldRed
, greenBold
, commentBgPurple
and so on ...)
$writer->bold->green->write('It is bold green');
$writer->boldGreen('It is bold green'); // Same as above
$writer->comment('This is grayish comment', true); // True indicates append EOL character.
$writer->bgPurpleBold('This is white on purple background');
Many colors with one single call: wrap text with tags <method>
and </end>
For NL/EOL just use <eol>
or </eol>
or <eol/>
.
Great for writing long colorful texts for example command usage info.
$writer->colors('<red>This is red</end><eol><bgGreen>This has bg Green</end>');
$writer->raw('Enter name: ');
Just pass array of assoc arrays. The keys of first array will be taken as heading. Heading is auto inflected to human readable capitalized words (ucwords).
$writer->table([
['a' => 'apple', 'b-c' => 'ball', 'c_d' => 'cat'],
['a' => 'applet', 'b-c' => 'bee', 'c_d' => 'cute'],
]);
Gives something like:
+--------+------+------+
| A | B C | C D |
+--------+------+------+
| apple | ball | cat |
| applet | bee | cute |
+--------+------+------+
Designing table look and feel
Just pass 2nd param $styles
:
$writer->table([
['a' => 'apple', 'b-c' => 'ball', 'c_d' => 'cat'],
['a' => 'applet', 'b-c' => 'bee', 'c_d' => 'cute'],
], [
// for => styleName (anything that you would call in $writer instance)
'head' => 'boldGreen', // For the table heading
'odd' => 'bold', // For the odd rows (1st row is odd, then 3, 5 etc)
'even' => 'comment', // For the even rows (2nd row is even, then 4, 6 etc)
'1:1' => 'red', // For cell in row 1 col 1 (1 based count, 'apple' in this example)
'2:*' => '', // For all cells in row 2 (1 based count)
'*:2' => '', // For all cells in col 2 (1 based count)
'b-c' => '', // For all columns named 'b-c' (same as '*:2' in this example)
'*:*' => 'blue', // For all cells in table (Set all cells to blue)
]);
You can define the style of a cell dynamically using a callback. You could then apply one style or another depending on a value.
$rows = [
['name' => 'John Doe', 'age' => '30'],
['name' => 'Jane Smith', 'age' => '25'],
['name' => 'Bob Johnson', 'age' => '40'],
];
$styles = [
'*:2' => function ($val, $row) {
return $row['age'] >= 30 ? 'boldRed' : '';
},
];
$writer->table($rows, $styles);
The example above only processes the cells in the second column of the table. Yf you want to process any cell, you can use the *:*
key. You could then customise each cell in the table
$rows = [
['name' => 'John Doe', 'age' => '30'],
['name' => 'Jane Smith', 'age' => '25'],
['name' => 'Alice Bob', 'age' => '10'],
['name' => 'Big Johnson', 'age' => '40'],
['name' => 'Jane X', 'age' => '50'],
['name' => 'John Smith', 'age' => '20'],
['name' => 'Bob John', 'age' => '28'],
];
$styles = [
'*:*' => function ($val, $row) {
if ($val === 'Jane X') {
return 'yellow';
}
if ($val == 10 || $val == 20) {
return 'boldPurple';
}
if (str_contains($val, 'Bob')) {
return 'blue';
}
return $row['age'] >= 30 ? 'boldRed' : '';
},
];
$writer->table($rows, $styles);
Note: Priority in increasing order:
odd
oreven
2:*
(row)*:2
orb-c <-> column name
(col)*:*
any cell in table1:1
(cell) = highest priority
If you want to display certain configurations (from your .env file for example) a bit like Laravel does (via the php artisan about
command) you can use the justify
method.
$writer->justify('Environment');
$writer->justify('PHP Version', PHP_VERSION);
$writer->justify('App Version', '1.0.0');
$writer->justify('Locale', 'en');
Gives something like:
Environment ........................................
PHP Version .................................. 8.1.4
App Version .................................. 1.0.0
Locale .......................................... en
You can use the sep
parameter to define the separator to use.
$writer->justify('Environment', '', ['sep' => '-']);
$writer->justify('PHP Version', PHP_VERSION);
Gives something like:
Environment ----------------------------------------
PHP Version .................................. 8.1.4
In addition, the text color, the background color and the thickness of the two texts can be defined via the 3rd argument of this method.
$writer->justify('Cache Enable', 'true', [
'first' => ['fg' => Ahc\Cli\Output\Color::CYAN], // style of the key
'second' => ['fg' => Ahc\Cli\Output\Color::GREEN], // style of the value
]);
$writer->justify('Debug Mode', 'false', [
'first' => ['fg' => Ahc\Cli\Output\Color::CYAN], // style of the key
'second' => ['fg' => Ahc\Cli\Output\Color::RED], // style of the value
]);
For more details regarding the different color options, see Custom style
Read and pre process user input.
$reader = new Ahc\Cli\Input\Reader;
// No default, callback fn `ucwords()`
$reader->read(null, 'ucwords');
// Default 'abc', callback `trim()`
$reader->read('abc', 'trim');
// Read at most first 5 chars
// (if ENTER is pressed before 5 chars then further read is aborted)
$reader->read('', 'trim', 5);
// Read but dont echo back the input
$reader->readHidden($default, $callback);
// Read from piped stream (or STDIN) if available without waiting
$reader->readPiped();
// Pass in a callback for if STDIN is empty
// The callback recieves $reader instance and MUST return string
$reader->readPiped(function ($reader) {
// Wait to read a line!
return $reader->read();
// Wait to read multi lines (until Ctrl+D pressed)
return $reader->readAll();
});
Whenever an exception is caught by Application::handle()
, it will show a beautiful stack trace and exit with non 0 status code.
Any console applications that are built on top of adhocore/cli can entertain autocomplete of commands and options in zsh shell with oh-my-zsh.
All you have to do is add one line to the end of ~/.oh-my-zsh/custom/plugins/ahccli/ahccli.plugin.zsh
:
compdef _ahccli <appname>
Example: compdef _ahccli phint
for phint.
That is cumbersome to perform manually, here's a complete command you can copy/paste/run:
mkdir -p ~/.oh-my-zsh/custom/plugins/ahccli && cd ~/.oh-my-zsh/custom/plugins/ahccli
[ -f ./ahccli.plugin.zsh ] || curl -sSLo ./ahccli.plugin.zsh https://raw.githubusercontent.com/adhocore/php-cli/master/ahccli.plugin.zsh
chmod 760 ./ahccli.plugin.zsh && cd -
This is also one time setup.
# Open .zshrc
nano ~/.zshrc
# locate plugins=(... ...) and add ahccli
plugins=(git ... ... ahccli)
# ... then save it (Ctrl + O)
# replace appname with real name eg: phint
echo compdef _ahccli appname >> ~/.oh-my-zsh/custom/plugins/ahccli/ahccli.plugin.zsh
Of course you can add multiple apps, just change appname in above command
Then either restart the shell or source the plugin like so:
source ~/.oh-my-zsh/custom/plugins/ahccli/ahccli.plugin.zsh
appname <tab> # autocompletes commands (phint <tab>)
appname subcommand <tab> # autocompletes options for subcommand (phint init <tab>)
