Idea plugin suggestion

[skybber]

Hello,

I've been using JitWatch for some time and appreciate its capabilities in analyzing JIT compilation in Java. I'd like to propose modifying JitWatch into a plugin for IntelliJ IDEA. Integrating it directly into the IDE could offer advantages like better interaction with source code and other tools provided by Idea.

I've developed a prototype plugin that appears as a Tool Window in IntelliJ. A short demo video is available here: https://youtu.be/cGskItzVZyQ

I think it wouldn't be too difficult to get this plugin to a usable state, and I'm willing to invest time into the project to develop its potential further. I'd be happy to contribute to the development and collaborate on making this integration a reality :)

Yes it is very promising, I can help and very interested !

Hi Chris !!

Hi @skybber @bourgesl there was an IDEA plugin for JITWatch built by @yole back in 2016 : #206

Maybe it's possible to extend that to achieve what you need?

Kind regards,

Chris

For reference, the code of my plugin is here: https://github.com/yole/jitwatch-intellij

I have read both plugins. Jitwatch is more advanced, jitwatch-idea provides better integration to IDEA. jitwatch is ~45k lines of code and it seems too much work to port it to Swing at once. It seems to me easier to make jitswatch working as IDEA plugin at first, than integrate with IDEA editor and then (optionally) switch it to Swing.

Hi @skybber what's the bigger problem you're trying to solve?

JITWatch works as a standalone desktop application on all platforms with a JavaFX UI. It also exposes the engine so you can run it headless, as a plugin, or with a different UI. There shouldn't need to be any changes to the core.

Kind regards,

Chris

Hi Chris, for me, the main issue was the seamless integration with the source code. I had trouble configuring JITWatch for a project with a large number of modules, so I made my own modifications that don't depend on the source code. I think that the infrastructure for integrating a decompiler and downloading source files from JAR files is currently missing in JITWatch? This could potentially be solved in IDEA. Another issue is the slowness of the time graphs displaying method compilations, which become useless when dealing with projects that have tens of thousands of compilations.
