README for the eric7 IDE

0. What is eric7?
eric7 is a full featured Python editor and IDE, written in Python. It is based
on the cross platform Qt UI toolkit, integrating the highly flexible Scintilla
editor control. It is designed to be usable as everyday quick and dirty editor
as well as being usable as a professional project management tool integrating
many advanced features Python offers the professional coder. eric7 includes a
plug-in system, which allows easy extension of the IDE functionality with
plug-ins downloadable from the net. For more details see

1. Installation
Installing eric7 is a simple process. There are various methods available.
Please choose the one best suited to your needs and skills. eric7 may be must
with Python 3, Qt5 and PyQt5.

1.1 Create a Python virtual environment for eric7
It is recommended to install eric7 into a Python virtual environment in order
to keep your Python distribution clean. In order to do that create it by
entering the following command in a terminal window.

**Linux, macOS**::

    python3 -m venv eric7_venv


    python.exe -m venv eric7_venv

Replace ``eric7_venv`` with the desired path to the directory for the virtual
environment. All further instructions will assume this environment name.

1.2a Variant 1: Installation via the "" script
This method results in the most complete install on all supported platforms.
After extracting the eric7 distribution archive just execute the following
command in a terminal window.

**Linux, macOS**::




Change the path to the Python executable appropriately. The installation script
will check for all prerequisites and will ask for confirmation to install
them. If the installation process needs tuning type
``~/eric7_venv/bin/python3 --help`` for some help. Using the
``--yes`` option answers yes to all questions automatically.

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 eric7.

During the installation process a file containing some information about the
installation will be created. If this is not desired, the ``--no-info``
command line option may be added to the above given install command.

1.2b Variant 2: Installation via the Python Package Index PyPI
This method is the easiest one but does not create a macOS® Application. Enter
the following command in a terminal window.

**Linux, macOS**::

    ~/eric7_venv/bin/python3 -m pip install --upgrade eric-ide


    eric7_venv\Scripts\python.exe -m pip install --upgrade eric-ide

Once the installation is finished navigate to the executable directory of
the Python virtual environment and execute the ``eric7_post_install`` script.
This will create application menu entries on Linux and desktop and start menu
entries on Windows® platforms.





1.3 Installation of Qt Tools via Qt online installer
In order to get the most out of eric7 it is recommended to install the Qt Tools
like ``Qt Designer`` or ``Qt Linguist``. The recommended way is this.

1. Download the Qt online installer from the Qt download site.

2. Install Qt by executing the installer.

3. Configure the path to the Qt tools on the ``Qt`` configuration page of the
   eric7 configuration dialog.

2. Installation of translations
The default distribution archive of eric7 includes all supported translations
already. If the above installation variant 1 was performed with this, you may
skip this section.

If the ``nolang`` archive was used, translations may be added later on by
downloading the desired language pack, extract it to a temporary directory
and execute the script (type

3. Running
Just call up eric7, 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 eric7_unittest. This will show the same
dialog (though with a little bit less functionality) as if started from within
eric7. The web browser can be started as a standalone program by executing the
eric7_browser script.

Please note, the first time you start eric7 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.

4. Running from the sources
If you want to run eric7 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.

5. Tray starter
eric7 comes with a little utility called "eric7_tray". This embeds an icon
in the system tray, which contains a context menu to start eric7 and all
it's utilities. Double clicking this icon starts the eric7 IDE.

6. Completions/Calltips
eric7 provides an interface to the QScintilla completion and call-tips
functionality. QScintilla2 comes with API files for Python and itself. PyQt4
and PyQt5 contain API files as well. These are installed by default. An API
file for eric7 is installed in the same place, if installation variant 1 was

In order to use completions and call-tips in eric7 please configure these
functions in the "Preferences Dialog" on the "Editor -> APIs", 
"Editor -> Autocompletion" and "Editor -> Calltips" pages.

Additional completions and call-tip providers are available through the eric7
plug-in system. See below for details.

7. Remote Debugger
In order to enable the remote debugger start eric7, 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 eric7 sources
include the script ````.

8. Passive Debugging
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.

9. Plug-in System
eric7 contains a plug-in system, that is used to extend eric7's 
functionality. Some plug-ins are part of eric7. 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.

10. Interfaces to additional software packages
At the moment eric7 provides interfaces to the following software

        This is part of the Qt distribution and is used to generate user
        This is part of the Qt distribution and is used to generate
        This is part of the Qt distribution and may be used to display help
        This is a distributed version control system available from
        <>. It is the one used by eric7 itself.
        This is another (and probably more widely known) distributed version
        control system. It is available from <>.
        This is a version control system available from
        <>. eric7 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 preferred.
        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 eric7 distribution. The original version is
        available from
        This is part of the standard Python distribution and is used to profile
        Python source code.

11. Internationalization
eric7 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 HMI might show English texts even if you have selected something else.
If you are missing eric7 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.

12. Window Layout
eric7 provides a configurable window layout. The visibility of the various tool
panes can be configured. The position of the shell pane may be configured as

13. Source code documentation
eric7 has a built in source code documentation generator, which is
usable via the command line as well. For further details please see
the file README-eric7-doc.rst.
