   1  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.

  10  
  11  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  
  38  Inline Help

  61  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  .. ))
