Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecom, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance.

OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems. It includes its own distributed database, applications to interface towards other languages, debugging and release handling tools.

Contributing to Erlang/OTP

Here are the instructions for submitting patches.

In short:

  • We prefer to receive proposed updates via email on the erlang-patches mailing list rather than through a pull request. Pull requests are not practical because we have a strict policy never to merge any untested changes to the development branch (the only exception being obviously correct changes, such as corrections of typos).

  • We merge all proposed updates to the pu (proposed updates) branch, typically within one working day.

  • At least once a day, the contents of the pu branch will be built on several platforms (Linux, Solaris, Mac OS X, Windows, and so on) and automatic test suites will be run. We will email you if any problems are found.

  • If a proposed change builds and passes the tests, it will be reviewed by one or more members of the Erlang/OTP team at Ericsson. The reviewer may suggest improvements that are needed before the change can be accepted and merged.

  • Once or twice a week, a status email called "What's cooking in Erlang/OTP" will be sent to the erlang-patches mailing list.
