A interactive PHP Shell
|
|
|
2 |
=======================
|
|
|
3 |
|
|
|
4 |
The more I work with other languages like python and ruby I like their way how they
|
|
|
5 |
work on problems. While PHP is very forgiving on errors, it is weak on the debugging
|
|
|
6 |
side. It was missing a simple to use interactive shell for years. Python and Ruby have
|
|
|
7 |
their ipython and iruby shell which give you a direct way to interact with the objects.
|
|
|
8 |
No need to write a script and execute it afterwards.

Starting the Shell
|
|
|
12 |
------------------
|
|
|
13 |
|
|
|
14 |
Starting with PHP_Shell 0.2.1 starting the shell is done by calling the shell-wrappers:
|
|
|
15 |
|
|
|
16 |
$ php-shell.sh
|
|
|
17 |
|
|
|
18 |
or on Windows
|
|
|
19 |
|
|
|
20 |
> php-shell.bat
|
|
|
21 |
|
|
|
22 |
Write your own wrapper
|
|
|
23 |
----------------------
|
|
|
24 |
|
|
|
25 |
Sometimes you want to write your own shell where you provide your own defaults, colours and
|
|
|
26 |
error-handlers.
|
|
|
27 |
|
|
|
28 |
<?php
|
|
|
29 |
error_reporting(E_ALL);
|
|
|
30 |
|
|
|
31 |
require "php-shell-cmd.php";
|
|
|
32 |
?>
|
|
|
33 |
|
|
|
34 |
and execute it with:
|
|
|
35 |
|
|
|
36 |
$ php -q php-shell.php
|
|
|
37 |
|
|
|

Shell Colours
|
|
|
62 |
-------------
|
|
|
63 |
|
|
|
64 |
The shell supports colours to seperate Exceptions from normal output of your
|
|
|
65 |
functions. To enable the colours you can to set:
|
|
|
66 |
|
|
|
67 |
>> :set background=dark
|
|
|
68 |
|
|
|
69 |
By default the colour-schemes 'plain' (the default), 'light' and 'dark' are
|
|
|
70 |
defined.
|
|
|
71 |
|
|
|
72 |
You can also register your own colour schemes:
|
|
|
73 |
|
|
|
74 |
>> $__shell->registerColourScheme( 'custom', array(
|
|
|
75 |
.. "default" => PHP_SHELL::C_LIGHT_RED, /* colour of the prompt */
|
|
|
76 |
.. "value" => PHP_SHELL::C_BLACK, /* colour of a return value */
|
|
|
77 |
.. "exception" => PHP_SHELL::C_RED, /* colour of a exception */
|
|
|
78 |
.. ))
|
|
|
79 |
