An unofficial Erlang grammar adaptation in ANTLR v4. Typically, the only one on the web.

It is merely extracted from the official non-standard grammar from Erlang/OTP sources.

It is meant for students and people who work on Erlang's syntax.

• antlr4
• Erlang's erlc for preprocessing purposes.

Generate the grammar from Erlang.g4 with:

:::bash
make clean all

Live debug with tree representation:

:::bash
make debug
…type Erlang forms…
^D

Preprocess files in src/ and check Erlang.g4 against preprocessed files in examples/:

:::bash
./check.sh src examples

Check Erlang.g4 against the whole Erlang/OTP's .erl sources:

:::bash
make check
