E3 core. Tools and library for building and testing software

Project description

The `e3` Project

[![CII Best Practices](](
[![Documentation Status](](

This present project (`e3`) is a Python framework to ease the development
of portable automated build systems (compilation, dependencies management,
binary code packaging, and automated testing).

The `e3` framework is split across multiple Python packages named `e3-<name>`
and sharing the same namespace: `e3`.

`e3-core` content

`e3-core` package is organized in several packages and modules:

- *anod*: build system handling dependencies management and binary code
packaging. This includes a driver that can parse `.anod` specification
- *archive*: support for reading and writing tar and zip archives
- *collection*: generic collections, e.g. an implementation of Direct Acyclic
- *decorator*: Python decorators, e.g. a memoize decorator
- *diff*: functions to compute a diff or apply it
- *electrolyt*: support for parsing build plans
- *env*: global environment handling
- *error*: `e3` exceptions
- *event*: interface for notifying external services
- *fingerprint*: support for creating a synthetic view of set of
conditions and determining whether those conditions have changed
or not.
- *fs*: high-level file system operations, using globbing, walk,...
- *hash*: computation of sha1, md5
- *log*: logging helpers
- *main*: main program initialization, command line parsing,...
- *mainloop*: generic loop for running jobs
- *net*: network utilities
- *net.http*: helper for sending http requests and downloading files
- *net.smtp*: helper for sending emails through smtp
- *os*: platform independent interface to Operating System functions
- *os.fs*: low-level file system operations, no logging involved
- *os.platform*: tools to detect the platform
- *os.process*: interface to run process, to control the execution time,...
- *os.timezone*: platform independent interface to get the machine timezone
- *platform*: generic interface for providing platform information
- *platform_db*: knowledge base for computing platform information
- *store*: interface to download and store resources in a store
- *sys*: `e3` information, sanity check, ...
- *text*: text formatting and transformation
- *vcs*: high level interface to VCS repositories
- *yaml*: helpers for parsing yaml data

See [e3-core documentation]( for
more details.


requires: Python 2.7.x (experimental support of Python >=3.4)

To install `e3`, run:
