jlox

A lox compiler using java. Uses Gradle for building it. Learning Gradle and Java on the go.

Prerequisites

• Java (I use openjdk 11.0.20.1)
• Gradle (optional ig, since ./gradlew is available)

Compile and Run

I am not sure what the proper way is, but I am using this janky way to run it from the jar file.

# build
./gradlew build

# run the interactive interpreter
java -cp lox/build/libs/lox.jar com.saivishnu.lox.lox

# or

# run the interpreter with a file containing the source code as input
java -cp lox/build/libs/lox.jar com.saivishnu.lox.Lox /path/to/file

Some examples for getting an idea of the syntax

1. Expression
   • -((1 + 2) / (1 \* 2));
2. Variable declaration
   • var a = 10;
   • var b = "abc";
   • var c = true;
3. Print statement
   • print "hello";
   • print 1 + 2;
   • print true;
4. Exit interactive mode
   • exit()
   • Ctrl + C
