Chris NewlandHey #Java friends,
I've made a new tool for exploring Java bytecode in an interactive website!
https://byte-me.dev
You can edit and compile programs, upload your own class files, and even explore the JDK core libraries.
Hope you find it useful!
Tomasz Tarczyลski@chriswhocodes Very cool! I've worked on a similar pet project parsing class files with a Go 'classloader' (to learn Go and at the same time dig deeper into Java internals), and learned quite a lot in the process.
@tarczynski Thanks! I needed a new class library for #JITWatch so I created https://github.com/chriswhocodes/ClassAct and then built Byte-Me as a simple test harness which got a bit out of control and became its own project :) Building your own tools is a great way to learn!
@chriswhocodes Indeed it is! Thanks again for sharing ๐
Brice Dutheil ๐ช๐บ๐บ๐ฆ๐๐๐@chriswhocodes I prefer the IDE experience though. E.g. with https://plugins.jetbrains.com/plugin/16970-byte-code-analyzer
Vardhan@chriswhocodes This is *amazing*, I wish i had it when i was writing my jvm compiler for an DSL. Adding the intellij decompiler will make a full circle !
@vrdhn Thanks for the kind words! Adding a decompiler is on my todo list along with better navigation (follow invokes through the bytecode where possible). I might also look at adding an execution environment which could help me achieve my goal of producing an online version of JITWatch :)
Tomasz Nurkiewicz@chriswhocodes Looks great! Any chances of open sourcing the whole website?
@nurkiewicz the bytecode parsing library is already open-sourced https://github.com/chriswhocodes/ClassAct and I will probably open-source my in-memory compiler. I'm still undecided about open-sourcing the webapp parts :)
@chriswhocodes @nurkiewicz is there a reason to not use ASM?
@BriceDutheil @nurkiewicz Personal development and learning :) Plus I need some particular functionality in a class lib for JITWatch so I built my own.
