Development

Makefile targets

  • make check
    • Type check the code, without std feature, excluding tests.
  • make check-tests
    • Type check the code, with std feature, including tests.
  • make test
    • Run tests.

Cargo.toml

ORML use Cargo.dev.toml to avoid workspace conflicts with project cargo config. To use cargo commands in ORML workspace, create Cargo.toml by running

  • cp Cargo.dev.toml Cargo.toml, or
  • make Cargo.toml, or
  • change the command to make dev-check etc which does the copy. (For the full list of make commands, check Makefile)

Web3 Foundation Grant Project

ORML is part of the bigger Open-Web3-Stack initiative, that is currently under a General Grant from Web3 Foundation. See Application details here. The 1st milestone has been delivered.
