tools: modernize shank example from Solita to Codama; re-enable in CI#61
Merged
Conversation
Solita is unmaintained and does not work on the current toolchain, so this example is reworked around Codama and modernised end to end. - Rename tools/shank-and-solita -> tools/shank-and-codama (Solita is gone). - Program: bump to borsh 1.x, shank 0.4.8, solana-program 4.0. Replace the removed solana_program::system_instruction with solana-system-interface and borsh try_to_vec with borsh::to_vec. Shank 0.4's #[seeds(...)] PDA codegen is broken (emits unparsable tokens) and is not emitted to the IDL, so seeds are dropped and PDAs derived explicitly via Car::find_pda / RentalOrder::find_pda. Make the crate standalone (empty [workspace]) so it pins its own deps/lock. - Regenerate the Shank IDL (origin "shank", u8 discriminants) and generate a @solana/kit TypeScript client with Codama via codama.ts. Remove .solitarc.js, .crates/, and the old Solita output. - Replace the devnet test with an in-process LiteSVM (npm) test that loads the built .so and exercises add_car/book_rental/pick_up_car through the generated client, asserting account state. Runs in CI with no network. - package.json scripts (build, generate-client, build-and-test) wired for native.yml; commit a fresh frozen pnpm-lock.yaml. Drop the stale .ghaignore entry; track the standalone program Cargo.lock via .gitignore exception. https://claude.ai/code/session_013dpnF6uSGWXjkJJZseqzcP

Summary
Modernizes the native "car rental service" example from the dead Solita client generator to Codama, and brings it onto the current toolchain so it runs in CI. Solita's last release was Nov 2023 (superseded by Kinobi → Codama); Shank is still actively maintained (0.4.8, Feb 2026) and remains the standard way to give a native (non-Anchor) program an IDL — so the Shank lesson is kept, only the client generator and the ancient deps are replaced.

Program (

shank-cli0.4.8 (origin: "shank").codama.tsgenerator:rootNodeFromAnchor(idl)(origin shank) →createFromRoot→@codama/renderers-jsintotests/generated/. Removed.solitarc.js,.crates/, and the old Solita output.Test (TS +
litesvmnpm, in-process — no devnet/bankrun):tests/test.tsloads the built.sointolitesvm(kit-based, so it interops with the Codama JS client) and runsadd_car → book_rental → pick_up_car, asserting on-chain account state. Run via Node's built-in test runner (node --import tsx --test), so failures actually propagate.CI:
