Show HN: I spent my vacation writing a modern JVM assembler

• jasm

  10 420 2.9 Java

  A JVM assembler for the modern age

There's a "cookbook" document in the repo, but it's not very comprehensive - I'd be more than happy to take PRs :) https://github.com/roscopeco/jasm/blob/develop/docs/cookbook...

• proguard

  7 2,582 7.6 Java

  ProGuard, Java optimizer and obfuscator

  

Something else that could make your code generation for your JVM language easier: ProGuardCORE (https://github.com/Guardsquare/proguard-core). It can be used to read, generate and analyse Java bytecode.

Some examples for code generation: ProGuard where the project originated (https://github.com/Guardsquare/proguard), Brainf*ck compiler (https://github.com/mrjameshamilton/bf), Lox compiler (https://github.com/mrjameshamilton/klox)

Disclaimer: I work at Guardsquare on ProGuardCORE so may be biased ;)

• jssembly

  1 121 10.0 Java

  Jssembly is a library that allows you to execute native assembly from Java.

• Maker

  6 47 8.7 Java

  Lightweight, full-featured, low-level dynamic Java class generator designed for ease of use.

  

For the code generation phase, it might be easier to bypass emitting a text-based assembly format and just use the ASM library directly. If you want something easier, I wrote a code generation library specifically for that purpose: https://github.com/cojen/Maker It also includes an example "Mini-C" language compiler.

• proguard-assembler

  1 63 3.9 Java

  Assembler and disassembler for Java class files

  

Nice project! At Guardsquare, we have a similar project: https://github.com/Guardsquare/proguard-assembler

One of the things we use it for is testing: we can craft specific bytecode sequences that we want to test; for example, it's useful to test cases we've seen in the wild (e.g. obfuscated code) or to create a test that doesn't rely on a specific compiler/version.
