Consola Python de QGIS¶

The Interactive Console¶

The interactive console is composed of a toolbar, an input area and an output one.

Consola¶

The console main features are:

• Code completion, highlighting syntax and calltips for the following APIs:
  • Python
  • PyQGIS
  • PyQt4
  • QScintilla2
  • osgeo-gdal-ogr
• Ctrl+Alt+Space to view the auto-completion list if enabled in the Opciones;
• Execute code snippets from the input area by typing and pressing Enter or Run Command;
• Execute code snippets from the output area using the Enter selected from the contextual menu or pressing Ctrl+E;
• Browse the command history from the input area using the Up and Down arrow keys and execute the command you want;
• Ctrl+Shift+Space to view the command history: double-clicking a row will execute the command. The Command History dialog can also be accessed from context menu of input area;
• Save and clear the command history. The history will be saved into the file ~/.qgis2/console_history.txt;
• Open QGIS API documentation by typing _api;
• Open PyQGIS Cookbook by typing _pyqgis.

Reuse executed commands from the output panel

You can execute code snippets from the output panel by selecting some text and pressing Ctrl+E. No matter if selected text contains the interpreter prompt (>>>, ...).

El Editor de código¶

Use the ^{Show editor} button to enable the editor widget. It allows editing and saving Python files and offers advanced functionalities to manage your code (comment and uncomment code, check syntax, share the code via codepad.org and much more). Main features are:

• Code completion, highlighting syntax and calltips for the following APIs:
  • Python
  • PyQGIS
  • PyQt4
  • QScintilla2
  • osgeo-gdal-ogr
• Ctrl+Space to view the auto-completion list.
• Sharing code snippets via codepad.org.
• Ctrl+4 Syntax check.
• Search bar (open it with the default Desktop Environement shorcut, usually Ctrl+F):
  • Use the default Desktop Environment shortcut to find next/previous (Ctrl+G and Shift+Ctrl+G);
  • Automatically find first match when typing in find box;
  • Set initial find string to selection when opening find;
  • Pressing Esc closes the find bar.
• Object inspector: a class and function browser;
• Go to an object definition with a mouse click (from Object inspector);
• Execute code snippets with the Enter selected command;
• Execute the whole script with the Run script command (this creates a byte-compiled file with the extension .pyc).

The Python Console editor

Opciones¶

Accessible either from the Console toolbar or the contextual menu of Console output panel or Code Editor, this adds further settings to manage and control the Python console behavior:

• Autocompletion: If checked the code completion is enabled. You can get autocompletion from current document, from installed APIs and both from APIs and current document.
• Autocompletion threshold: Sets the threshold to display the autocompletion list (in chars typed).
• Automatic parentheses insertion: If checked enables the autoclosing for bracket.
• Auto-save script before running: Allows you to save automatically the script to be executed in order to avoid to save it after any modification. This action will store a temporary file into the temporary system directory that will be automatically deleted after running.
• Using preloaded APIs file: You can choose whether use the preload APIs file or load some APIs files saved on your system.
• Using prepared APIs file: If checked the *.pap file will be used for code completion. To generate a prepared APIs file you have to load at least an *.api file and then compile it by clicking on [Compile Apis...] button.
