Recently I began to migrate some of the code on Chlorine to REPL Tooling, so things may become more testable. I already found multiple bugs in this approach and began an integration test methodology using Electron (I say that there are three kinds of developers in the field of automated tests – the ones that don’t test, the ones that do, and test freaks. I’m probably the later).
In the beginning, the idea would be to rewrite the renderer of results and exceptions so that I could fix lots of bugs that they have. So far, it’s progressing slowly, but I already can render datomic results in a meaningful way (the last renderer was interpreting as Java objects, which they indeed are) and fix some bugs with tags and other issues.
Now, one of the things that I wanted in the new renderer is the ability to copy/paste results in a meaningful way – as I’m using UNREPL, there are lots of tags that need to be reinterpreted, like
#unrepl/browseable for datafy. These need to be “translated” to something useful for rendering on screen, with links to navigate inner details, but for copy-paste they should have a textual representation that makes sense (probably the hard part).
The results of all these experiments are quite interesting – when you evaluate something and th result is a Java object, there’s a link
... that can be used to navigate inside the object: it’ll show getters, the current class, methods that the object supports, so things like “goto definition for Java object” or “Javadocs” aren’t really necessary.
