# OptsLib
|
|
|
|
A very simple Options parser and command-line arguments
|
|
handling library for PHP.
|
|
|
|
## Installation
|
|
|
|
The library can be installed using ncc:
|
|
|
|
```bash
|
|
ncc install -p "nosial/libs.opts=latest@n64"
|
|
```
|
|
|
|
or by adding the following to your project.json file under
|
|
the `build.dependencies` section:
|
|
|
|
```json
|
|
{
|
|
"name": "net.nosial.optslib",
|
|
"version": "latest",
|
|
"source_type": "remote",
|
|
"source": "nosial/libs.opts=latest@n64"
|
|
}
|
|
```
|
|
|
|
If you don't have the n64 source configured you can add it
|
|
by running the following command:
|
|
|
|
```bash
|
|
ncc source add --name n64 --type gitlab --host git.n64.cc
|
|
```
|
|
|
|
## Compiling from source
|
|
|
|
The library can be compiled from source using ncc:
|
|
|
|
```bash
|
|
ncc build --config release
|
|
```
|
|
|
|
or by running the following command:
|
|
|
|
```bash
|
|
make release
|
|
```
|
|
|
|
## Usage
|
|
|
|
The usage of this library is very simple, there are
|
|
two functions that you can use to parse options.
|
|
|
|
### parseArgument()
|
|
|
|
Can be used to parse a single argument string/array, this is useful for
|
|
parsing command line arguments. The second argument is the maximum number
|
|
of arguments that can be parsed, this is to prevent infinite loops.
|
|
|
|
```php
|
|
<?php
|
|
|
|
require_once('ncc');
|
|
import('net.nosial.optslib', 'latest');
|
|
|
|
$input = '--foo --bar="test" -y --username test';
|
|
$parsed = \OptsLib\Parse::parseArgument($input);
|
|
|
|
echo $parsed['foo']; // true
|
|
echo $parsed['bar']; // "test"
|
|
echo $parsed['y']; // true
|
|
echo $parsed['username']; // "test"
|
|
```
|
|
|
|
### getArguments()
|
|
|
|
This method is used to access the `$argv` array
|
|
if it's not set, an empty array is returned.
|
|
|
|
```php
|
|
<?php
|
|
|
|
require_once('ncc');
|
|
import('net.nosial.optslib', 'latest');
|
|
|
|
$arguments = \OptsLib\Parse::getArguments();
|
|
|
|
echo $arguments['output-file']; // "test.txt"
|
|
echo $arguments['input-file']; // "test.txt"
|
|
echo $arguments['log']; // "verbose"
|
|
```
|
|
|
|
Optionally, if you want arguments after a specific argument/option
|
|
to be parsed, you can pass the argument name as the first argument.
|
|
|
|
This is ideal if you are using a command line tool that has
|
|
a sub-command, for example:
|
|
|
|
```bash
|
|
$ mytool subcommand --foo --bar="test" -y --username test
|
|
```
|
|
|
|
In this case, you can pass the `subcommand` argument to the
|
|
`getArguments()` method to parse the arguments after it.
|
|
|
|
```php
|
|
<?php
|
|
|
|
require_once('ncc');
|
|
import('net.nosial.optslib', 'latest');
|
|
|
|
$arguments = \OptsLib\Parse::getArguments('subcommand');
|
|
|
|
echo $arguments['foo']; // true
|
|
echo $arguments['bar']; // "test"
|
|
echo $arguments['y']; // true
|
|
echo $arguments['username']; // "test"
|
|
```
