man Padre (3): Perl Application Development and Refactoring Environment

SYNOPSIS

Padre is a text editor aimed to be an IDE for Perl.

After installation you should be able to just type in

padre

and get the editor working.

Padre development started in June 2008 and made a lot of progress but there are still lots of missing features and the development is still very fast.

Getting Started

After installing Padre you can start it by typing padre on the command line. On Windows that would be Start/Run padre.bat

You can start new files File/New ("Ctrl+N") or open existing files File/Open ("Ctrl+O").

You can edit the file and save it using File/Save ("Ctrl+S").

You can run the script by pressing Run/Run Script ("F5")

By default Padre uses the same Perl interpreter for executing code that it uses for itself but this will be configurable later.

FEATURES

Instead of duplicating all the text here, let us point you to the web site of Padre <http://padre.perlide.org/> where we keep a list of existing and planned features. We are creating detailed explanation about every feature in our wiki: <http://padre.perlide.org/trac/wiki/Features/>

DESCRIPTION

Configuration

The application maintains its configuration information in a directory called .padre.

Other

On Strawberry Perl you can associate .pl file extension with C:\strawberry\perl\bin\wxperl and then you can start double clicking on the application. It should work...

Run This ("F5") - run the current buffer with the current Perl this currently only works with files with .pl extensions.

Run Any ("Ctrl+F5") - run any external application

First time it will prompt you to a command line that you have to type in such as

  perl /full/path/to/my/script.pl

...then it will execute this every time you press "Ctrl+F5" or the menu option. Currently "Ctrl+F5" does not save any file. (This will be added later.)

You can edit the command line using the Run/Setup menu item.

Please Note that you can use $ENV{PADRE_VERSION} to detect whether the script is running inside Padre or not.

Navigation

  Ctrl+2          Quick Fix
  Ctrl+.          Next Problem
 
  Ctrl+H opens a help window where you can see the documentation of
  any Perl module. Just use open (in the help window) and type in the name
  of a module.
  Ctrl+Shift+H Highlight the name of a module in the editor and then
  press Ctrl+Shift+H. It will open the help window for the module
  whose name was highlighted.
  In the help window you can also start typing the name of a module. When the
  list of the matching possible modules is small enough you'll be able
  to open the drop-down list and select the name.
  The "small enough" is controlled by two configuration options in the
  Edit/Setup menu:
  Max Number of modules
  Min Number of modules
  This feature only works after you have indexed all the modules
  on your computer. Indexing is currently done by running the following command:
  padre --index

SQLite

Padre is using an SQLite database (~/.padre/config.db) for two things. Part of the preferences/configuration information is kept there and it is used for the POD reader.

Documentation POD reader

Padre currently can index (the names of) all the modules on your system and it was planned to have a search capability for modules/functions/etc.

Plug-ins

There is a highly experimental but quite simple plug-in system.

A plug-in is a module in the "Padre::Plugin::*" namespace.

At start-up time Padre looks for all such modules in @INC and in its own private directory and loads them.

Every plug-in must be a subclass of Padre::Plugin and follow the rules defined in the Padre::Plugin API documentation.

See also Padre::PluginManager and Padre::PluginBuilder

While Padre is running there is a menu option to show the plug-in configuration window that shows the list of all the plug-ins.

TO DO: What to do if a newer version of the same plug-in was installed?

TO DO: What to do if a module was removed ? Shall we keep its data in the configuration file or remove it?

TO DO: Padre should offer an easy but simple way for plug-in authors to declare configuration variables and automatically generate both configuration file and configuration dialog. Padre should also allow for full customization of both for those more advanced in Wx.

Tab and space conversion

Tab to Space and Space to Tab conversions ask the number of spaces each tab should substitute. It currently works everywhere. We probably should add a mode to operate only at the beginning of the lines or better yet only at the indentation levels.

Delete All Ending space does just what it says.

Delete Leading Space will ask How many leading spaces and act accordingly.

ARCHITECTURE

Padre.pm

is the main module.

Padre::Autosave

describes some of our plans for an auto-save mechanism. It is not implemented yet. (There is also some description elsewhere in this document).

Padre::Config

reads/writes the configuration files.

There is an SQLite database and a YAML file to keep various pieces of information. The database holds host related configuration values while the YAML file holds personal configuration options.

The SQLite database holds the list of modules available on the system. It will also contain indexing of the documentation Looking at the "" entries of modules List of functions

Padre::DB

The SQLite database abstraction for storing Padre's internal data.

Padre::Document

is an abstraction class to deal with a single document.

Padre::Document::PASM
Padre::Document::PIR
Padre::Document::Perl

Padre::PluginBuilder

Padre::PluginManager

locates and loads the plug-ins.

Padre::Plugin

Should be the base class of all plug-ins.

Padre::Pod2HTML

Padre::PPI

Padre::Project

Abstract class understanding what a project is.

Padre::Project::Perl

Is a Perl specific project. These are work in process. Not yet used.

Padre::TaskManager

Managing background tasks.

Padre::Task

Background tasks.

Padre::Util

Various utility functions.

Wx GUI

The "Padre::Wx::*" namespace is supposed to deal with all the Wx related code.

Padre::Wx
Padre::Wx::App: is the Wx::App subclass. Does not really do much.
Padre::Wx::Dialog::Bookmarks
Padre::Wx::Dialog::Find: This is the main Find dialog
Padre::Wx::Panel::FindFast: This is the newer Firefox like inline search box.
Padre::Wx::Dialog::PluginManager
Padre::Wx::Dialog::Preferences
Padre::Wx::Dialog::Snippets
Padre::Wx::FileDropTarget: The code for drag and drop
Padre::Wx::Editor: holds an editor text control instance (one for each buffer/file). This is a subclass of Wx::Scintilla::TextCtrl also known as Scintilla.
Padre::Wx::ComboBox::History
Padre::Wx::TextEntryDialog::History
Padre::Wx::Main: This is the main window, most of the code is currently there.
Padre::Wx::Menu: handles everything the menu should know and do.
Padre::Wx::Output: the output window at the bottom of the editor displaying the output of running code using "F5".
Padre::Wx::HtmlWindow
Padre::Wx::Frame::POD
Padre::Wx::Popup: not in use.
Padre::Wx::Printout: Implementing the printing capability of Padre.
Padre::Wx::SyntaxCheck: Implementing the continuous syntax check of Perl code.
Padre::Wx::ToolBar: handles everything the toolbar should know and do.

METHODS

The "Padre" class itself provides a number of convenience methods.

ide

  my $ide = Padre->ide;

The static "ide" method returns the Padre singleton object if the IDE has been created, or throws an exception if the IDE has not been created.

new

  my $ide = Padre->new(%options);

The "new" constructor creates the new singleton Padre object, or throws an exception if the IDE has already been created.

It takes a set of parsed command line options as a parameter, storing them until they are needed at startup.

wx

  my $app = Padre->wx;

The static "wx" method is a convenience wrapper around the underlying global variable $Wx::TheApp provided by the Wx module.

For convenience reasons, it can also be used as an instance method.

Returns a Wx::App object, or "undef" if the application object has not yet been created.

run

  $padre->run;

The "run" method starts the Padre IDE and enters the Wx main loop.
