JOJ3

Quick Start

To register the sandbox executor, you need to run go-judge before running this program. Install go-judge and start it with go-judge -enable-grpc

For developers

Install pre-commit, golangci-lint, goimports, gofumpt.

Then install the pre-commit hooks. It will run some checks before you commit.

$ pre-commit install
pre-commit installed at .git/hooks/pre-commit

Models

The program parses the TOML file to run multiple stages.

Each stage contains an executor and parser.

Executor takes a Cmd and returns an ExecutorResult.

Parser takes an ExecutorResult and its conf and returns a ParserResult and bool to indicate whether we should skip the rest stages.

Cmd

Check Cmd at https://github.com/criyle/go-judge#rest-api-interface.

Some difference:

• CopyInCwd bool: set to true to add everything in the current working directory to CopyIn.
• CopyInCached map[string]string: key: file name in the sandbox, value: file name used in CopyOutCached.
• LocalFile: now supports the relative path

ExecutorResult

Check the Result at https://github.com/criyle/go-judge#rest-api-interface.

ParserResult

• Score int: score of the stage.
• Comment string: comment on the stage.
