# pwasm-utils
> :warning: **This repository/crate is deprecated and unmaintained**: Switch to [`wasm-instrument`](https://github.com/paritytech/wasm-instrument) in order to use wasm instrumentation (gas metering, stack height limiter) in your project. For wasm code optimization [`binaryen`](https://github.com/WebAssembly/binaryen) should be used.
A collection of WASM utilities used in pwasm-ethereum and substrate contract development.
This repository contains the package `pwasm-utils` which consists of a library crate
and a collection of cli binaries that make use of this library.
## Installation of cli tools
```
cargo install pwasm-utils --features cli
```
This will install the following binaries:
* wasm-build
* wasm-check
* wasm-ext
* wasm-gas
* wasm-pack
* wasm-prune
* wasm-stack-height
## Symbols pruning (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 purposes, a raw WASM contract can be injected with gas counters (the same way as it done in the `pwasm-ethereum/substrate` runtime when running contracts)
```
wasm-gas
```
