Installation
# PHP8.0 and above v1.0.0 composer require adhocore/cli:^v1.0.0 # PHP 7.x composer require adhocore/cli:^v0.9.0
Usage
Argv parser
$command = new Ahc\Cli\Input\Command('rmdir', 'Remove dirs'); $command ->version('0.0.1-dev') // Arguments are separated by space // Format: `<name>` for required, `[name]` for optional // `[name:default]` for default value, `[name...]` for variadic (last argument) ->arguments('<dir> [dirs...]') // `-h --help`, `-V --version`, `-v --verbosity` options are already added by default. // Format: `<name>` for required, `[name]` for optional ->option('-s --with-subdir', 'Also delete subdirs (`with` means false by default)') ->option('-e,--no-empty', 'Delete empty (`no` means true by default)') // Specify santitizer/callback as 3rd param, default value as 4th param ->option('-d|--depth [nestlevel]', 'How deep to process subdirs', 'intval', 5) ->parse(['thisfile.php', '-sev', 'dir', 'dir1', 'dir2', '-vv']) // `$_SERVER['argv']` ; // Print all values: print_r($command->values()); /*Array ( [help] => [version] => 0.0.1 [verbosity] => 3 [dir] => dir [dirs] => Array ( [0] => dir1 [1] => dir2 ) [subdir] => true [empty] => false [depth] => 5 )*/ // To get values for options except the default ones (help, version, verbosity) print_r($command->values(false)); // Pick a value by name $command->dir; // dir $command->dirs; // [dir1, dir2] $command->depth; // 5
Command help
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:
Command version
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
Console app
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!
Git app
$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
Organized app
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'); $this ->argument('<arrg>', 'The Arrg') ->argument('[arg2]', 'The Arg2') ->option('-a --apple', 'The Apple') ->option('-b --ball', 'The ball') // 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/>' ); } // 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'); $app->handle($_SERVER['argv']); // if argv[1] is `i` or `init` it executes InitCommand
Grouping commands
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')); ...
Exception handler
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);
App help
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:
App version
Same version number is passed to all attached Commands. So you can trigger version on any of the commands.
Shell
Very thin shell wrapper that provides convenience methods around proc_open()
.
Basic usage
$shell = new Ahc\Cli\Helper\Shell($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)
Advanced usage
$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();
Timeout
$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();
Cli Interaction
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
$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
Single choice
$fruits = ['a' => 'apple', 'b' => 'banana']; $choice = $interactor->choice('Select a fruit', $fruits, 'b'); $interactor->greenBold("You selected: {$fruits[$choice]}", true);
Multiple choices
$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);
Prompt free input
$any = $interactor->prompt('Anything', rand(1, 100)); // Random default $interactor->greenBold("Anything is: $any", true);
Prompt with validation
$nameValidator = function ($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);
IO Components
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
Color looks cool!
$color = new Ahc\Cli\Output\Color;
Simple usage
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');
Custom style
Ahc\Cli\Output\Color::style('mystyle', [ 'bg' => Ahc\Cli\Output\Color::CYAN, 'fg' => Ahc\Cli\Output\Color::WHITE, 'bold' => 1, // You can experiment with 0, 1, 2, 3 ... as well ]); echo $color->mystyle('My text');
Cursor
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
Progress Bar
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 | +---------------+------------------------------------------------------+---------------+
Writer
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');
Output formatting
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');
Free style
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>');
Raw output
$writer->raw('Enter name: ');
Tables
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
Justify content (Display setting)
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
Reader
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(); });
Exceptions
Whenever an exception is caught by Application::handle()
, it will show a beautiful stack trace and exit with non 0 status code.
Autocompletion
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:
One time setup
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 -
Load ahccli plugin
This is also one time setup.
# Open .zshrc nano ~/.zshrc # locate plugins=(... ...) and add ahccli plugins=(git ... ... ahccli) # ... then save it (Ctrl + O)
Registering app
# 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
Trigger autocomplete
appname <tab> # autocompletes commands (phint <tab>) appname subcommand <tab> # autocompletes options for subcommand (phint init <tab>)
