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%

:alt: Trying to run ``init:boot/1``
Tests in ``priv/test2.erl`` work. Running ``make test`` tries to run ``init:boot/1`` and produces the output above.
Compiling
`````````
* 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 `_
* 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
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).
Reference Material
``````````````````
* `BEAM Wisdoms `_ (I run this one)
* `The BEAM book `_
(I am also one of the editors there)
