JOJ3

Quick Start

In order to register the sandbox executor, you need to run go-judge before running this program.

$ export CONF_GITEATOKEN="<YOUR_TOKEN>" && make clean && make && ./examples/success/run.sh && ./examples/compile_error/run.sh
rm -rf ./build/*
rm -rf *.out
go build -o ./build/joj3 ./cmd/joj3
++ dirname -- ./examples/success/run.sh
+ DIRNAME=./examples/success
+ cd ./examples/success
+ ./../../build/joj3
+ cat ./joj3_result.json
[{"Name":"compile","Results":[{"Score":0,"Comment":""}]},{"Name":"run","Results":[{"Score":100,"Comment":"executor status: run time: 2811900 ns, memory: 16658432 bytes"},{"Score":100,"Comment":"executor status: run time: 2578200 ns, memory: 13094912 bytes"}]}]
+ rm -f ./joj3_result.json
+ cd -
++ dirname -- ./examples/compile_error/run.sh
+ DIRNAME=./examples/compile_error
+ cd ./examples/compile_error
+ ./../../build/joj3
+ cat ./joj3_result.json
[{"Name":"compile","Results":[{"Score":0,"Comment":"Unexpected executor status: Nonzero Exit Status."}]}]
+ rm -f ./joj3_result.json
+ cd -

For developers

Install pre-commit, golangci-lint, goimports.

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 parse the TOML file to run multiple stages.

Each stage contains a executor and parser.

Executor takes a Cmd and returns a ExecutorResult.

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

Cmd

Check Cmd in 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 sandbox, value: file name used in CopyOutCached.
• LocalFile: now support relative path

ExecutorResult

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

ParserResult

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