Polkadot SDK Version Manager

This is a simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file.

Installation

cargo install --git https://github.com/paritytech/psvm psvm

Usage

Go to the directory containing the Cargo.toml file you want to update and run psvm. This will automatically update the Polkadot SDK dependencies in the Cargo.toml file to their correct crates.io version.

If you want to update the local dependencies (using path="..."), you can use the -o or -overwrite flag, this will remove the path and set a crates.io version instead.

If you want to update the dependencies to a specific Polkadot SDK version, you can use the -v or --version flag, followed by the version you want to update to.

# Go to the directory containing the Cargo.toml file you want to update
cd <cargo-toml-dir>
# Run the psvm command to update the dependencies
psvm
# You can also update it using the path to the Cargo.toml file
psvm -p <cargo-toml-dir>/Cargo.toml
# Overwrite local dependencies with crates.io versions
psvm -o
# Update to a specific Polkadot SDK version (default 1.3.0)
psvm -v "1.7.0"

Maintenance

To update the Polkadot SDK dependencies mapping, run ./scripts/update.sh <polkadot-sdk repo path>. This will update the dependencies json files located in src/versions with the latest versions defined in Polkadot SDK crates-io branches.

You can add more branches in the BRANCHES list from ./scripts/update.sh file. Once you have process the branches, you need to index them in the src/versions.rs file.
