README

This library helps to create command line (CLI) operator for PHP in Windows, Mac and Linux

Features

✅ Windows, Linux and Mac Compatible.

✅ This library truly minimalist and simple, it only consists of 2 classes and nothing more and no external dependency.

✅ Arguments & user input

✅ This library was aimed to (optionally) fallback to user-input if the argument is missing.

✅ Colors available

✅ The design is mostly fluent (it adjusts to the width of the screen)

✅ Validation of values

✅ Support NO_COLOR environment variable. See https://no-color.org/

Getting started

Add the library using composer:

composer require eftec/clione

And create a new instance of the library

$cli=new CliOne(); // instance of the library

Usage

For example, let's say we need to create a CLI code to read an information and save into a file.

>php basic.php read -o result.json

We have two arguments, the first (read) is in the first position, and it doesn't have any "-". The second is "-o" that it is our flag with a value.

So we could create our arguments.

$cli=new CliOne();
$cli->createParam('read',[],'first')->add(); // a positional argument (the first one) value-less
$cli->createParam('o',[],'flag')->add(); // a simple flag "-o"

And we could evaluate as

$cli->evalParam('read');
$cli->evalParam('o');
// So we could obtain our values as:
var_dump($cli->getParameter('read')->value); 
var_dump($cli->getParameter('o')->value);
// or as
var_dump($cli->getValue('read'));
var_dump($cli->getValue('o'));

It will return false if we don't set a value, and it will return the value it we set it.

>php basic.php read -o result.json
string(4) "read"
string(11) "result.json"

The parameters are created and evaluated separately because it allows to do more powerful operations with it.

For example, sometimes we want to show the help (the list of parameters available) without evaluating the parameters.

Ok, but now what if we want to create an alias of "-o"

var_dump($cli->getParameter('o',['output','outputresult'])->value);

So we could call using this line

php basic.php read --output result.json
# or also
php basic.php read --outputresult result.json
# or also
php basic.php read -o=result.json

If the parameter is a flag, then the alias is a longflag ("--"). If the parameter is a longflag then the alias is a flag.

But let's say we need to ask for a password, however we want to be entered interactively.

$cli->createParam('pwd',[],'flag') // we create the parameter
    ->setInput(true,'password') // and we ask (if the parameter is not entered as flag) 
                                //for user input of the type password (however the password is not hidden visually)
    ->add();
$cli->evalParam('pwd');   // and don't forget to evaluate the parameter

So it will look like:

> php .\basic.php read -o result.json
Select the value of pwd [*****] :123

Now, let's say something more advanced, multiple options, we want to select the type of file: json, csv, html and xml

Our code

$cli->createParam('type',[],'flag')
    ->setInput(true,'option',['json','csv','xml','html'])
    ->add();

And the result:

PS > php .\basic.php read -o result.json
Select the value of pwd [*****] :111
[1] json                     
[2] csv                      
[3] xml                      
[4] html                     
Select the value of type [] :2 #you could use TAB key for autocomplete, cool!

List of values are divided in two values, the visual value (simply called value), and the key-value.. In this example, "csv" is a value and its key-value is "2".

The list of values allows associative arrays and indexed arrays. Indexed arrays are renumbered to start in 1.

You could also enter

php .\basic.php read -o result.json -pwd 123 -type json

Now, you can show the parameters ("show the syntax help") as follows:

$cli->showParamSyntax2('parameters:');

But it will look plain.

It is because you can add a description, change the question and add more help information

$cli->createParam('type',[],'flag')
    ->setDescription('it is the type of output','what is the option?',['it is the help1','example: -option xml'])
    ->setInput(true,'option',['json','csv','xml','html'])
    ->add();

So it will look like: (in colors)

parameters:
read                         The command [read]
-o, --output, --outputresult The output file without extension [result.json]
                             example: -o file
-pwd                         It is the password [*****]
-type                        it is the type of output [csv]
                             it is the help1
                             example: -option xml

There are more operations available but the basic is there.

CliOne
Table of contents

Flow

(optional) you can set the current value using the method setParam()
If the type of parameter is not "onlyinput" and "none", then it reads the parameter
- Example: php program.php -param1 value --param2 -param3="hello world" parampositional
If the parameter is found, then it is returned, end of the flow.
If the parameter is not found then
- If setCurrentAsDefault() is set, and the current value is not null, then the default value is the current value.
- Otherwise, the default value is the value set using the method setDefault(). If none, then it uses null.
if input is true setInput(true) then it asks to user-input the value
- if the user doesn't fill the information, then it returns the default value (if any), end of the flow
- if the user fills the information, but it is incorrect, then it asks again and again.
- if the user fills the right information, then it returns this value, end of the flow
if input is true setInput(false) then
- Note: we were unable to read the values of the argument, and we don't want to read from user input.
- it returns the default value, and it could raise an error, end of the flow

Note:

isRequired() if the value is missing, then it shows an error.
setAllowEmpty() if the value is empty (not missing), then it allows to enter an empty value

Input as arguments

php mycli.php subcommandfirst subcommandsecond -flag valueflag --longflag valueflag2 subcommandlatest

The system allows reading multiple types of arguments

first: this argument does not have value, and it is position (in the very first position), it must be not be prefixed with a "-", otherwise it would be considered a flag instead of a positional argument.

cliprogram.php first # the value obtained is "first".

command: it is similar to first, but it does not compare the name of the argument.

cliprogram.php com -flag # first returns "com" if the argument is named first.  command returns "com" regardless of its name.

second: this argument is also positional (second position) and does not have any value

cliprogram.php first second -someflag # the value obtained is "second"

last: this argument is also positional, and it is always at the latest argument

cliprogram.php first second  last # the value obtained is "last"

flag: the argument is prefixed with a single "-". This argument not need to be a single character.

cliprogram.php -flag hello # the value of the flag called "flag" is "hello"

longflag: the argument is prefixed with a double "--"

cliprogram.php --flag hello # the value of the doubleflag called "flag" is "hello"

onlyinput/none: the system never read it as argument, so it could be user-input.
- none means that the argument is only user-input, and it must not be stored.

cliprogram.php  # "onlyinput/none" could not be obtained via command line

The argument could be created as:

// program.php -f hello
// or
// program.php -f=hello
// or
// program.php -f "hello world"
$cli->createParam('f','flag')->add();  // add() is important otherwise the parameter will not be create.

And it could be read as:

$result=$cli->evalParam('name'); // $result->value will return "hello"

Now, what if you want to create multiples alias for the same parameter.

// program.php -h 
// or
// program.php --help 
$cli->createParam('h','flag',['help'])->add();  // it adds an alias longflag called "help"

Input interactive

There are several configuration to set an input interactively.

By default, every parameter is read as argument. If the value is read as argument, then it is not asked interactively.

However, if the parameter is of the type "none" or "onlyinput", then they are only obtained by user input ( interactively).

Example:

$cli->$t->createParam('paramname',[],'none');

User input (interactive)

With the method setInput() we set that this parameter could also be read interactively.

$cli->$t->createParam('paramname',[],'none')->setInput();

Example, let's say the next example:

$cli=new CliOne();
$cli->createParam('p1',[],'none')
    ->setInput()
    ->add(); // we create the param
$cli->evalParam('p1'); // and we evaluated the parameter

Now, this input accepts any kind of text. But there is many kind of user input.

Option returns a value and a value-key. Value is the content visible. And value-key, is the content selected by the user.

Example Option:

$cli=new CliOne();
$cli->createParam('p1',[],'none')
    ->setInput(true,'option2',['key1'=>'value1','key2'=>'value2','key3'=>'value3','key4'=>'value4'])
    ->add(); // we create the param
$cli->evalParam('p1');
$cli->showLine("value :".$cli->getValue('p1'));
$cli->showLine("valuekey :".$cli->getValueKey('p1'));

Example Multiple:

$cli=new CliOne();
$cli->createParam('p1',[],'none')
    ->setInput(true,'option2',['key1'=>'value1','key2'=>'value2','key3'=>'value3','key4'=>'value4'])
    ->add(); 
$cli->evalParam('p1'); // value returns an associative array with the values selected, example: ["value1","value3"]

Customize user input

It is possible to customize the input by changing the help description, changing the question, showing an example or showing a value to the argument

$cli=new CliOne();
$cli->createParam('p1',[],'none')
    ->setInput()
    ->setDescription('it is for help','what is the value of p1?',['help line1','help line 2'],'the argument is called p1')
    ->add(); 
$cli->evalParam('p1');

Method addMenuItem()

It adds a menu item.
Example:

$this->addMenu('menu1');
// if op1 is selected then it calls method menufnop1(), the prefix is for protection.
$this->addMenuItem('menu1','op1','option #1','fnop1');
// if op1 is selected then it calls method menuop2()
$this->addMenuItem('menu1','op2','option #2');
$this->addMenuItem('menu1','op3','go to menu2','navigate:menu2');

return 'EXIT'; // if any function returns EXIT (uppercase), then the menu ends (simmilar to "empty to
exit")
}

If action starts with "navigate:" then it opens the menu indicated.
If action is "exit:" then exit of the menu.
If action is callable, then it calls the function (string|null|callable)

Method addMenuItems()

It adds multiples items to a menu

[index=>description]
(array|null)

Method addMenuService()

It adds a service object to be evaluated when we run evalMenu()
You can add menu services. Every service is evaluated in order, so if both service objects has the same method, then it is only called by the first object.
If evalMenu() uses a service then, the services defined here are ignored.
Example:

$objService=new Class1();
$this->addMenuService('menu1',$objService);
// or:
$this->addMenuService('menu1',Class1:class);

Parameters:

$idMenu The unique name of the menu (string)
$caller The caller object(s). It is used to the events and actions.
If null, then it use the services defined by addMenuService();
If it is an array, then it calls the first object that has the method
If this argument is used then addMenuService() is ignored (object|null|array)

Examples

Example using arguments

example/example1.php

And create the next code

// example1.php
// don't forget to add autoloader, namespace, etc.
$cli=new CliOne(); // instance of the library
if($cli->isCli()) { // we validate if we are running a CLI or not.
  $cli->createParam('param1') // the name of the parameter
        ->setDescription('Some description','question?') // description and question
        ->setRequired(true) // if the field is required
        ->setDefault('param1') // the default value If the value is not found
        ->add(); // it adds a parameter to the cli
  $param1=$cli->evalParam('param1'); // then we evaluate the parameter.
  var_dump($param1->value);  
}

So you can run as:

Example using user input

You can ask for user input of the user.

example/example2.php

$cli=new CliOne();
if($cli->isCli()) {
    $cli->createParam('param1')
        ->setDescription('This field is called param1 and it is required')
        ->setInput(true,'string')
        ->setRequired(true)
        ->setDefault('param1')
        ->add();
    $param1 = $cli->evalParam('param1');
    var_dump($param1->value);
}

It will show the next result

Types of user input

Types of colors

Definitions

You can find the definition of the classes, methods and fields at:

definitions.md

debug

To activate the debug mode, you must set the debug field as true:

$cli=new CliOne();
$cli->debug=true;

In debug mode, every user input is recored in the field $debugHistory

You can also see the history running the input ??history

And you can clear the history using the input ??clear

The goal is we could store a session and replace it using testUserInput()

You can also load and save the user input

??history it shows the history
??clear it clears the history
??load it load the user input and runs it.
??save it saves the user input in a file called _save.json
??load:file ??save:file you can also specify the filename where it will be saved

$cli = new CliOne();
CliOne::testUserInput([...]); // put your story here.

Compatibility

It must support all moderns interface that are compatibles with Virtual Terminal.
Since Windows TH2 (v1511, 2015), cmd.exe and powershell.exe has supports or VT, but it must be enabled.
- REG ADD HKCU\CONSOLE /f /v VirtualTerminalLevel /t REG_DWORD /d 1
Since Windows 10 Anniversary Edition (v1607, 2016), cmd.exe and powershell.exe has default supports of VT (AFAIK)
Windows 2019 (LTS, 2018) supports this library by default.
Windows Terminal supports all features.
The screen size width is -1 column less in older version of Windows. C'mon, Microsoft!
