JOJ3

Quick Start

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

$ make clean && make && ./_example/simple/run.sh
rm -rf ./build/*
rm -rf *.out
go build -o ./build/joj3 ./cmd/joj3
++ dirname -- ./_example/simple/run.sh
+ DIRNAME=./_example/simple
+ cd ./_example/simple
+ ./../../build/joj3

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.

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.
