Ethereum assembler / disassembler.

All dependencies are fetched and installed automatically provided you start with `python`_ and `pip`_.

This project only supports `pip`_ -based installation. The author also recommends `virtualenv`_.

Now: Clone this repository, then from the repository root, run pip install .

Future: Run pip install ethasm.

It's easiest to start by disassembling some bytecode to get a feel for the syntax:

$ ethasm -d < ./path/to/serpent-compile-output

FIXME: serpent outputs hex... either disassemble from hex or provide serpent-to-bytecode instructions.

Assembling the output of disassembly should produce bytewise identical code:

$ ethasm -d < ./path/to/serpent-compile-output | ethasm > /tmp/reassembled
$ diff -q ./path/to/serpent-compile-output /tmp/reassembled || echo 'Reassembly produced different output.'

Note however, that the output of disassembly is a subset of the (future / planned) assembler language.

The (future) goal is to track Ethereum PoC6 and later. In the future the python package version will reflect the target Ethereum bytecode version, in a manner similar to pyethereum's version.

This is still a hard-to-use proof-of-concept. The codebase is straddling PoC5 / PoC6 and incoherent.

• Full unit test coverage, developing tests to specify PoC6 bytecode (based on `pyethereum`_) and the assembler language.
• Define a python package versioning scheme to track Ethereum specs. Probably 0.N.j where N is the PoC<N> specification, and j is an incrementing integer unique to ethasm (and distinct from `pyethereum`_).
• Publish to pypi and announce in Ethereum venues.
