eric  6-19.04
About: Eric is a full featured Python and Ruby editor and IDE (written in python; based on Qt and Scintilla).
  Fossies Dox: eric6-19.04.tar.gz  ("inofficial" and yet experimental doxygen-generated source code documentation)  

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies eric6-19.04.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).
README for the eric6 IDE

Installing eric6 is a simple process. Just execute the script (type python -h for some help). Please note that the installation has to be performed using the administrators account (i.e. root on linux). This installs a wrapper script called eric6 in the standard executable directory.

If you want to uninstall the package just execute the script. This gets rid of all installed files. In this case please send an email to the below mentioned address and tell me your reason. This might give me a hint on how to improve eric6.

eric6 may be used with any combination of Python 3 or 2, Qt5 or Qt4 and PyQt5 or PyQt4. If the required packages (Qt5/4, QScintilla2, sip and PyQt5/4) are not installed, please get them and install them in the following order (order is important).

  1. Install Qt5 (from The Qt Company)
  2. Build and install QScintilla2 (from Riverbank Computing)
  3. Build and install sip (from Riverbank Computing)
  4. Build and install PyQt5 (from Riverbank Computing)
  5. Build and install QScintilla2 Python bindings (part of the QScintilla2 package)
  6. Install eric6

If you want to use the interfaces to other supported software packages, you may install them in any order and at any time.

Please note, that the QScintilla2 Python bindings have to be rebuild, if the PyQt5 package gets updated. If this step is omitted, a bunch of strange errors will occur.

Note: This section is valid for PyQt4 and PyQt5 before 5.7.0.

Installing eric6 on Windows® is even easier. Just download the PyQt5 installer from Riverbank Computing and use it to install PyQt5. This includes all the required Qt5 libraries and tools as well as QScintilla. Once this installation is completed install eric6. That's all.

Note: This section is valid for PyQt5 5.7.0 or newer.

Installing eric6 and its pre-requisites is even easier using the PyQt5 Python wheels. In order to have access to the suite of Qt tools and documentation it is recommended to install the Qt development environment. These tools are not part of the PyQt5 wheels. Users of the Windows® operating system may use the 'pyqt5-tools' wheel available via the Python Package Index (PyPI) as of 2017-05-12.

  1. Download the Qt online installer from the Qt download site.
  2. Install Qt by executing the installer.
  1. Install the Qt tools by entering this command in a command window:
    pip install pyqt5-tools
  1. Install the eric6 pre-requisites (PyQt, sip and QScintilla) by entering this command in a shell / command window:

    pip install qscintilla

    or :

    pip3 install qscintilla

    This will install QScintilla and all dependencies, which are PyQt5 and sip.

  2. Install eric6 and configure the path to the Qt tools on the Qt page of the configuration dialog.
  3. Once the eric6 IDE is started the Qt documentation may be loaded into the eric web browser via the Settings ➡ Mange Qt Help Documents menu entry.

Translations of the eric6 IDE are available as separate downloads. There are two ways to install them.

The first possibility is to install them together with eric6. In order to do that, simply extract the downloaded archives into the same place as the eric6 archive and follow the installation instructions above.

The second possibility is to install them separately. Extract the downloaded archives and execute the script (type python -h for some help). This way you can make the translations available to everybody or just to the user executing the installation command (if using the -p switch).

Just call up eric6, which will start the IDE. Use the "what is"-help (arrow with ?) to get some help. The eric web site provides some documents describing certain aspects of eric. To start the unit test module in a standalone variant simply call up eric6_unittest. This will show the same dialog (though with a little bit less functionality) as if started from within eric6. The web browser can be started as a standalone program by executing the eric6_webbrowser script.

Please note, the first time you start eric6 it will recognize, that it hasn't been configured yet and will show the configuration dialog. Please take your time and go through all the configuration items. However, every configuration option has a meaningful default value.

If you want to run eric6 from within the source tree you have to execute the script once after a fresh checkout from the source repository or when new dialogs have been added. Thereafter just execute the script.

eric6 comes with a little utility called "eric6\_tray". This embeds an icon in the system tray, which contains a context menu to start eric6 and all it's utilities. Double clicking this icon starts the eric6 IDE.

eric6 provides an interface to the QScintilla auto-completion and calltips functionality. QScintilla2 comes with API files for Python and itself. PyQt4 and PyQt5 contain API files as well. These are installed by default, if the correct installation order (see above) is followed. An API file for eric6 is installed in the same place.

In order to use autocompletion and calltips in eric6 please configure these functions in the "Preferences Dialog" on the "Editor -\> APIs", "Editor -\> Autocompletion" and "Editor -\> Calltips" pages.

In order to enable the remote debugger start eric6, open the preferences dialog and configure the settings on the debugger pages.

The remote login must be possible without any further interaction (i.e. no password prompt). If the remote setup differs from the local one you must configure the Python interpreter and the Debug Client to be used in the Preferences dialog. Use the script to install the debug client files and set the entries of the a.m. configuration page accordingly.

To ease the installation process of the debug client, the eric6 sources include the script

Passive debugging mode allows the startup of the debugger from outside of the IDE. The IDE waits for a connection attempt. For further details see the file README-passive-debugging.rst.

eric6 contains a plug-in system, that is used to extend eric6's functionality. Some plug-ins are part of eric6. Additional plugins are available via the Internet. Please use the built-in plug-in repository dialog to get a list of available (official) plug-ins and to download them. For more details about the plug-in system please see the documentation area.

At the moment eric6 provides interfaces to the following software packages.

  • Qt-Designer
    This is part of the Qt distribution and is used to generate user interfaces.
  • Qt-Linguist
    This is part of the Qt distribution and is used to generate translations.
  • Qt-Assistant
    This is part of the Qt distribution and may be used to display help files.
  • Mercurial
    This is a distributed version control system available from <>. It is the one used by eric6 itself.
  • Subversion
    This is a version control system available from <>. eric6 supports two different Subversion interfaces. One is using the svn command line tool, the other is using the PySvn Python interface <>. The selection is done automatically depending on the installed software. The PySvn interface is prefered. This automatism can be overridden an a per project basis using the "User Properties" dialog.
    This is a tool to check Python code coverage. A slightly modified version is part of the eric6 distribution. The original version is available from <>
  • tabnanny
    This is a tool to check Python code for white-space related problems. It is part of the standard Python installation.
  • profile
    This is part of the standard Python distribution and is used to profile Python source code.

eric6 and its tools are prepared to show the UI in different languages, which can be configured via the preferences dialog. The Qt and QScintilla translations are searched in the translations directory given in the preferences dialog (Qt page). If the translations cannot be found, some part of the MMI might show English texts even if you have selected something else. If you are missing eric6 translations for your language and are willing to volunteer for this work please send me an email naming the country code and I will send you the respective Qt-Linguist file.

eric6 provides different window layouts. In these layouts, the shell window and the file browser may be embedded or be separat windows.

eric6 has a built in source code documentation generator, which is usable via the commandline as well. For further details please see the file README-eric6-doc.rst.

eric6 (and the others) is released under the conditions of the GPL. See separate license file for more details. Third party software included in eric6 is released under their respective license and contained in the eric6 distribution for convenience.
