# `eth_abi_lite` `eth_abi_lite` is a lite fork of `eth_abi`, aiming to support EVM abi encode/decode functionality without external dependencies on `eth_utils`, `eth_typing`, `toolz`, or `cytoolz`. `eth_abi_lite` can be used as a drop-in replacement for `eth_abi==3.0.0`. Install with `pip install eth_abi_lite` #### Motivation 1) Many packages in the ethereum ecosystem have conflicting version requirements for dependencies such as `eth_utils`, `eth_typing`, `toolz`, or `cytoolz`. Removing these dependencies allows a package to be used in more environments. 2) These dependencies are rather heavy if all you want is basic abi encoding/decoding functionality. #### Does `eth_abi_lite` work the same as `eth_abi`? `eth_abi_lite` can be used as a drop-in replacement for `eth_abi==3.0.0`. The one functional difference is that `eth_abi`'s low level pad functions are no longer curry-able. In most cases this difference will not be noticed. `eth_abi_lite` passes `eth_abi`'s standard test suite when running `tox`: ``` ... ======================== 751 passed, 3 skipped in 18.45s ======================== ____________________________________ summary ____________________________________ py37-core: commands succeeded py38-core: commands succeeded py39-core: commands succeeded py310-core: commands succeeded congratulations :) ``` (tests for linting and docs removed) #### Is `eth_abi_lite` faster? According to testing with [tuna](https://github.com/nschloe/tuna) on a good laptop: - `eth_abi_lite` takes about **18 ms** to import - `eth_abi` takes about **180 ms** to import `eth_abi_lite` is faster to import because it loads fewer dependencies. This is useful in the context of cli tools where startup times matter. ## Survey of imported items `eth_abi_lite` imports the following items from its dependencies: #### Items Imported From `eth_utils` - `big_endian_to_int` - `compose_if_tuple` - `int_to_big_endian` - `is_address` - `is_boolean` - `is_bytes` - `is_integer` - `is_list_like` - `is_number` - `is_text` - `to_canonical_address` - `to_checksum_address` - `to_normalized_address` - `to_tuple` #### Items Imported From `eth_typing` - `TypeStr` - `Decodable` #### Items Imported From `eth_utils.toolz` - `toolz.functoolz.curry` ## The Changes The changes from `eth_abi` to `eth_abi_lite` consist mostly of copying portions of `eth_utils` and `eth_typing`. The basic idea is that every time something is imported from `eth_utils` or `eth_typing`, that thing is instead imported from a lite version of that package. #### Step 1. Create `eth_utils_lite` Copy these items from `eth_utils` to `eth_utils_lite` - `eth_utils/abi.py` - `eth_utils/address.py` - `eth_utils/conversions.py` - `eth_utils/crypto.py` - `eth_utils/decorators.py` - `eth_utils/encoding.py` - `eth_utils/functional.py` - `eth_utils/hexadecimal.py` - `eth_utils/types.py` The only non-mutual dependency in these modules is `eth_hash.keccak()` in `eth_utils/crypto.py`. Replace this function with `pycryptodome`'s keccak implementation directly. Also in `eth_utils/functional.py`, remove the functions that are decorated by `toolz.compose`. It is possible to prune these files more aggressively, but leaving the files unchanged minimizes the chances of introducing bugs. #### Step 2. Create `eth_typing_lite` Copy these items from `eth_typing` to `eth_typing_lite`: - `Address` - `AnyAddress` - `ChecksumAddress` - `Decodable` - `HexAddress` - `HexStr` - `Primitives` - `TypeStr` These are all of the `eth_typing` types used by `eth_abi_lite` and `eth_utils_lite`. #### Step 3. Create `eth_abi_lite` 1. Copy all files from `eth_abi` into `eth_abi_lite` 2. Replace all instances of - `eth_utils` with `eth_utils` - `eth_typing` with `eth_typing_lite` - `eth_abi` with `eth_abi_lite` 3. Replace the `toolz.curry` decoration on `eth_abi.zpad` and `eth_abi.fpad` with `functools.partial` decoration.
