4. Infra
The @walnut_dev team has been shipping, and here’s what landed this week:
• Faster Storage View for better debugging
• Cleaner revert messages
• Smarter handling of deserialization errors
🥜🔩 Weekly Nuts & Bolts 🔩🥜
This week was all about making Walnut more reliable and predictable. Here’s what we shipped:
1️⃣ Optimized data handling in the Storage View tab more performant debugging
2️⃣ Fixed a bug that caused excessive memory use when inputs failed to deserialize
3️⃣ Calldata now always shows in raw format—even if deserialization fails
4️⃣ Removed duplicate raw result entries from Call Trace Details
5️⃣ Revert error messages skip ASCII control chars for cleaner output
6️⃣ Fixed incorrect Sierra version selection based on class hash
scarb cairo-run is deprecated!
It's replaced by scarb execute:
• Runs & compiles in one step
• New targets: standalone or bootloader
• Prove & verify with scarb prove + scarb verify
🚀 Heads up Cairo Devs! scarb cairo-run is being deprecated. Meet its successor: scarb execute!
scarb execute runs functions directly from your local Scarb package. It even compiles your code automatically, so no need for scarb build first (unless you want to skip with --no-build).
Requires an executable target in your Scarb.toml.
