feat: aztec new supporting multiple contract crates by benesjan · Pull Request #21007 · AztecProtocol/aztec-packages

Summary

aztec new previously created a workspace with fixed crate directories named contract/ and test/. This made it impossible to add a second contract to the same workspace, since the directory names would collide.

This PR restructures the scaffold so that:

Crate directories are named after the contract: aztec new counter creates counter_contract/ and counter_test/ instead of contract/ and test/.
aztec new supports adding contracts to an existing workspace: when run inside a directory that already has a Nargo.toml with [workspace], it adds a new contract+test crate pair and appends the members to the workspace manifest.
New add_crate.sh script: extracted the crate-creation logic from setup_workspace.sh into a reusable add_crate.sh so it can be called both during initial setup and when adding subsequent contracts.
setup_workspace.sh simplified: now just creates the workspace root Nargo.toml with empty members and delegates to add_crate.sh.
Counter contract test fixture updated: the counter_contract directory under noir-projects/noir-contracts/contracts/test/ is restructured from counter_contract/{contract,test} to counter/{counter_contract,counter_test} to match the new naming convention.
Type generation scripts updated: the sed patterns in generate-types.sh for both noir-contracts.js and noir-test-contracts.js are adjusted to handle the new deeper directory nesting.

Test plan

aztec-up/test/default_scaffold.sh — verifies creating a new workspace and adding a second contract
aztec-up/test/counter_contract.sh — verifies the counter contract compiles and codegens with the new directory layout
Existing noir-contracts compilation (workspace member paths updated in Nargo.toml)

Correct me if I'm wrong because bash is not my strong suit, but wouldn't this cause
aztec new counter --name foo to use the name "foo" for the contract?
Should we fail for now unknown params?

I don't follow. --name has been dropped so it's now irrelevant

The command creates a contract crate called foo_contract in workspace foo.

I meant that since we were allowing unknown commands, only the last word would be considered the project name. Reading it back, I wasn't clear at all

I also don't understand bash but AI seems to have done it correctly 🤣
