# pwasm-utils
|
|
|
|
[](https://travis-ci.org/paritytech/wasm-utils)
|
|
|
|
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 <input_wasm_binary.wasm> <output_wasm_binary.wasm>
|
|
```
|
|
|
|
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)
|
|
|
|
```
|
|
wasm-gas <input_wasm_binary.wasm> <output_wasm_binary.wasm>
|
|
```
