# wasm-utils [![Build Status](https://travis-ci.org/paritytech/wasm-utils.svg?branch=master)](https://travis-ci.org/paritytech/wasm-utils) Collection of WASM utilities used in pwasm-ethereum and substrate contract development ## Build tools for cargo Easiest way to use is to install via `cargo install`: ``` cargo install pwasm-utils-cli --bin wasm-build ``` ## Symbols pruning (wasm-prune) ``` cargo install pwasm-utils-cli --bin wasm-prune wasm-prune ``` This will optimize WASM symbols tree to leave only those elements that are used by contract `call` function entry. ## Gas counter (wasm-gas) For development puposes, raw WASM contract can be injected with gas counters (the same way as it done by pwasm-ethereum/substrate runtime when running contracts) ``` cargo install pwasm-utils-cli --bin wasm-gas wasm-gas ``` ## API All executables use corresponding api methods of the root crate and can be combined in other build tools. # License `wasm-utils` is primarily distributed under the terms of both the MIT license and the Apache License (Version 2.0), at your choice.
