FAQ: What kind of patches will be approved?

Here are some informal guidelines on what kind of patches that are likely to be accepted or rejected, based on policies and/or the history of rejection/acceptance in the past.

Can I add an environment variable to configure some behavior or limit of the emulator?

No. We don’t want to add any new environment variables. Implement a new command line option to configure the behavior (example of an accepted patch). Any command line option can be passed in the environment variable ERL_FLAGS.
