ErlangRT - Runtime
Erlang Replacement Therapy. This is an attempt to make Erlang runtime (BEAM emulator) in Rust. This is not the first attempt so I kinda know what I'm doing.
Progress to the Proof of Concept
- Term library 80% (remaining 80% are in progress)
- External Term Format (decoder 70%, encoder 0%)
- BEAM Loader - mostly done
- VM and processes 40%
- VM loop and opcodes 45% (74 of 168)
- Some basic BIFs <15%
- Binaries, sub-binaries, binary heap, binary opcodes: <20%
priv/test2.erl work. Running
make test tries to run
init:boot/1 and produces the output above.
The source assumes that you have Erlang OTP 22+ source in a Git submodule in
otp/, and the stdlib and preload BEAM files are compiled and ready. Makefile takes care of it.
Install latest Rust and Cargo via Rustup
makeand 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
make test- runs the tests
make build-rel- builds but does not run the debug and the release target respectively
Currently the emulator expects to have preloaded BEAM modules from OTP 22+ located in otp/ Git submodule (Makefile takes care of it).
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).
