Development

Setting up Rust Tests

Run the build.sh script with the name of the program to build the shared object and put it in a directory called test-programs in the root of the project.

E.g.:

./build.sh auction-house

Running with all builds all programs.

Versioning and Publishing Packages

Smart contract SDK packages are versioned independently since a contract isn't necessarily coupled to other contracts.

We use the following (pre|post)(version|publish) npm scripts to manage related checks, tagging, committing and pushing the version bump.

• preversion: ensures that the package builds and its tests pass
• postversion: adds and commits the version bump and adds a tag indicating package name and new version, i.e. @metaplex-foundation/mp-core@v0.0.1
• prepublishOnly: ensures that the package builds and its tests pass again (just to be really sure)
• postpublish: pushes the committed change and new tag to GitHub

In order to version and then publish a package just run the following commands from the folder of the package you want to update:

• npm version <patch|minor|major>
• npm publish

As you note if version + publish succeeds the scripts end up pushing those updates to the master branch. Therefore, please ensure to be on and up to date master branch before running them. Please don't ever publish from another branch but only from the main one with only PR approved changes merged.
