appmap-ruby VS appmap-java

AppMap currently supports Ruby, Java, Python, and Javascript projects and the libraries are MIT licensed.

Yes, sure. I've added a link to the docs above, and the repo is here - https://github.com/applandinc/appmap-ruby

Well, I’m definitely biased, but we welcome devs at all XP levels at the appmap project. Take a look. If you can’t find a good first issue @ Dan, Dustin, Kevin, or Petr in the Discord and someone will hook you up. https://github.com/applandinc/appmap-ruby We have needs from doc to core features!

In order to help make this a reality, we have created the open source AppLand Framework. The AppLand Framework includes components to:

AppLand is an open source framework that developers can use to record, analyze, and optimize end-to-end code and data flows. The framework provides client agents for Ruby, Java and Python (beta) that record running code and generate JSON files called AppMaps. Users can view and analyze AppMaps locally using the AppMap extension for VS Code, and also push AppMaps to the AppLand server for analytics, sharing, discussion etc.

Now, what if you want to be able to efficiently fetch a subset of JSONB data, without having to load and parse every object? At AppLand, we store AppMap data in the database. Each AppMap has a mandatory section called metadata, and we want to be able to efficiently pull out the metadata of selected rows without having to parse the entire JSONB column (the metadata is usually less than 1% of the total JSON object). Awesomely, since PostgreSQL 12, PostgreSQL has a feature called generated columns.

Install the appmap gem by following the instructions in the README. Here's a quick checklist:

AppMap currently supports Ruby, Java, Python, and Javascript projects and the libraries are MIT licensed.

Add the appmap Java agent to your Maven or Gradle configuration - or just download the JAR file from https://github.com/applandinc/appmap-java/releases

found bug when having empty app.yml: https://github.com/applandinc/appmap-java/issues/80 but if filled out it works.

Hey that’s cool. Something has to trigger AppMap to start and stop recording. Tests are one way; each test defines the boundary of a recording. Another way is to wrap the code you want to run using this function - https://github.com/applandinc/appmap-java/blob/f11ab539f3d2572e1c6583db5fadccb4483c50eb/src/main/java/com/appland/appmap/record/Recorder.java#L229 - see also https://github.com/applandinc/appmap-java/blob/f11ab539f3d2572e1c6583db5fadccb4483c50eb/src/main/java/com/appland/appmap/record/Recorder.java#L58 - LMK if you get it working - you will need an appmap.yml of course.
