eric can be downloaded at SourceForge and installed manually with a python installer script.[2] Most major Linux distributions include eric in their software repositories, so when using such Linux distributions eric can be obtained and installed automatically by using the package manager of the particular distribution.[3] Additionally, the author offers access to the source code via a public Mercurial repository.[4]
Characteristics
eric is written in Python and uses the PyQt Python bindings for the QtGUI toolkit.[5] By design, eric acts as a front end for several programs, for example the QScintilla editor widget.[6]
Integrated graphical python debugger which supports both interactive probing while suspended and auto breaking on exceptions as well as debugging multi-threaded and multiprocessing applications
Integrated automatic code checkers (syntax, errors and style, PEP-8) for static program analysis as well as support of Pylint via plug-in
Integrated source code documentation system
Integrated unit testing support by having the option to run python code with command-line parameters
Integrated interface to the enchant spell checking library
Integrated interface to cx_freeze (as optional plug-in)
Many integrated wizards for regex and Qt dialogs (as core plug-ins)
Tools for previewing Qt forms and translations
Support for Python 2 and 3
Prior to the release of eric version 5.5.0, eric version 4 and eric version 5 coexisted and were maintained simultaneously, while eric 4 was the variant for writing software in Python version 2 and eric version 5 was the variant for writing software in Python version 3.
With the release of eric version 5.5.0 both variants had been merged into one, so that all versions as of eric version 5.5.0 support writing software in Python 2 as well as in Python 3, making the separate development lanes of eric version 4 and 5 obsolete. Those two separate development lanes are no longer maintained, and the last versions prior to merging them both to 5.5.0 were versions 4.5.25 and 5.4.7.[8]

Releases
Versioning scheme
Until 2016, eric used a software versioning scheme with a three-sequence identifier, e.g. 5.0.1. The first sequence represents the major version number which is increased when there are significant jumps in functionality, the second sequence represents the minor number, which is incremented when only some features or significant fixes have been added, and the third sequence is the revision number, which is incremented when minor bugs are fixed or minor features have been added.
From late 2016, the version numbers show the year and month of release, e.g. 16.11 for November 2016.[9]
Release strategy
eric follows the development philosophy of Release early, release often, following loosely a time-based release schedule. Currently a revision version is released around the first weekend of every month, a minor version is released annually, in most cases approximately between December and February.
Version history
The following table shows the version history of eric, starting from version 4.0.0. Only major (e.g. 6.0.0) and minor (e.g. 6.1.0) releases are listed; revision releases (e.g. 6.0.1) are omitted.

Several allusions are made to the British comedy group Monty Python, which the Python programming language is named after. Eric alludes to Eric Idle, a member of the group, as does IDLE, the standard python IDE shipped with most distributions.[16][failed verification]
