命令速查与工作流

• 构建

mvn -q -DskipTests clean package

• 运行与调试

java -jar target/my-language-0.1.0-SNAPSHOT.jar examples/hello.lxg
java -jar target/my-language-0.1.0-SNAPSHOT.jar examples/hello.lxg --dump-tokens
java -jar target/my-language-0.1.0-SNAPSHOT.jar examples/hello.lxg --dump-parse-tree | cat
java -jar target/my-language-0.1.0-SNAPSHOT.jar examples/hello.lxg --dump-ast
java -jar target/my-language-0.1.0-SNAPSHOT.jar examples/hello.lxg --emit-class=out/Program.class
javap -v out/Program.class | sed -n '1,200p'

• 测试

mvn -q test
mvn -q -Dtest=LexerSmokeTest test
mvn -q -Dtest=LxgEndToEndTest test

• 推荐工作流
  1. 修改 g4/AST/生成
  2. 逐层开启 dump 验证
  3. 运行单测与示例
  4. 必要时导出 .class 与 javap -v
