ErlangRT - Runtime

Erlang Replacement Therapy. Another attempt to make Erlang runtime (BEAM emulator) in Rust.

  • The good news: I know what to do.
  • The bad news: I have no clue how to Rust, but will learn.

Progress to the Proof of Concept

  • Term library 70%
  • External Term Format (decoder 70%, encoder 0%)
  • BEAM Loader 95%
  • VM and processes 30%
  • VM loop and opcodes 20%
  • Some basic BIFs 5%
Test2.erl run output

Tests in priv/test2.erl partially work and would produce the output above.

Compiling

  • Install latest Rust and Cargo via Rustup

  • Run make and with the magic of Bash autocomplete see which targets it supports. You might like:

    • make run - runs the executable with test args, whatever set by the developer, do not expect it to show any magical tricks;
    • make doc - builds doc pages in target/doc/erlang_rt/
    • make test - runs the tests
    • make build and make build-rel - builds but does not run the debug and the release target respectively

Editing and Code Navigation

I am using and strongly recommend IntelliJ IDEA CE (free version) with IntelliJ-Rust plugin (available in repositories tab inside IntelliJ).
