SYNOPSIS


use Config::Model::TkUI;
# init trace
Log::Log4perl->easy_init($WARN);
# create configuration instance
my $model = Config::Model -> new ;
my $inst = $model->instance (root_class_name => 'a_config_class',
instance_name => 'test');

DESCRIPTION

This class provides a GUI for Config::Model.

With this class, Config::Model and an actual configuration model (like Config::Model::Xorg), you get a tool to edit configuration files (e.g. "/etc/X11/xorg.conf").

USAGE

Left side tree

•
Click on '+' and '-' boxes to open or close content
•
Left-click on item to open a viewer widget.
•
Double-click or hit ``return'' on any item to open an editor widget
•
Use Ctrl-C to copy configuration data in an internal buffer
•
Use Ctrl-V to copy configuration data from the internal buffer to the configuration tree. Beware, there's no ``undo'' operation.
•
Before saving your modifications, you can review the change list with the menu entry "File -> show unsaved changes". This list is cleared after performing a "File -> save".
•
Pasting cut buffer into:
  • a leaf element will store the content of the buffer into the element.
  • a list element will split the content of the buffer with /\n/ or /,/ and push the resulting array at the end of the list element.
  • a hash element will use the content of the cut buffer to create a new key in the hash element.

Search

Hit "Ctrl-F" or use menu "Edit -> Search" to open a search widget at the bottom of the window.

Enter a keyword in the entry widget and click on "Next" button.

The keyword will be searched in the configuration tree, in element name, in element value and in documentation.

Editor widget

The right side of the widget is either a viewer or an editor. When clicking on store in the editor, the new data is stored in the tree represented on the left side of TkUI. The new data will be stored in the configuration file only when "File-"save> menu is invoked.

Wizard

A wizard can be launched either with "File -> Wizard" menu entry or with "Run Wizard" button.

The wizard will scan the configuration tree and stop on all items flagged as important in the model. It will also stop on all erroneous items (mostly missing mandatory values).

Methods

save(callback)

Save modified data in configuration file. The callback function is called only if the save was done without error. The callback is called with $@ in case of failed save.

TODO

- add tabular view ? - expand the whole tree at once - add plug-in mechanism so that dedicated widget
  can be used for some config Class (Could be handy for
  Xorg::ServerLayout)

FEEDBACK and HELP wanted

This project needs feedback from its users. Please send your feedbacks, comments and ideas to : 

  config-mode-users at lists.sourceforge.net

This projects also needs help to improve its user interfaces:

  • Look and feel of Perl/Tk interface can be improved
  • A nicer logo (maybe a penguin with a wrench...) would be welcomed
  • Config::Model could use a web interface
  • May be also an interface based on Gtk or Wx for better integration in Desktop

If you want to help, please send a mail to: 

  config-mode-devel at lists.sourceforge.net
