Right now if there is a diff between the actual and expected results,
the expected file will be overwritten. This may be annoying. To make it
controlled we introduce BLESS option.
This means that the expected files won't be regenerated unless this
environment variable is set.
Therefore to regenerate the tests use:
BLESS=1 cargo test
pwasm-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>
