Implementing a Fuzzier font option using Junie

Collaborating with Junie on implementing font family setting for Fuzzier

On the last PR I let Junie handle all coding. On this one I use my normal collaborative workflow.

  1. Junie: Initial setup - Added the new setting and created tests (normally copy-paste work for me)
  2. Junie: API work - Handled the editor font API call (would’ve been googling/doc-reading for me)
  3. Me: Review & refactor - Went through the changes, tested functionality and did some refactoring
  4. Junie: Code review - Suggested improvements (null safety, caching)
  5. Both: Implementation - Applied the improvements together
  6. Me: Documentation - Updated docs and some minor tweaks (wording etc.)

Full PR - #142.

Implementing a config feature to Fuzzier using Junie

Junie implementing global exclusions

I let Junie implement a new feature to Fuzzier. Here are some thoughts about that.

You can checkout the full PR below. I only wrote the changelog, but all other changes were made by Junie.

fuzzier - #141.

It’s not that simple

Evaluating pros and cons of AI is hard (for me).

Prompting

Nothing special going on.

The whole process took 3 separate tasks

Attempted agentic migration

Migrating from Mockito to MockK

Iteration 1

Okay

Prompt

Lets migrate from mockito to mockk because this is a kotlin project

Result

Actually took the right steps for the update:

  • Replaced the dependency
  • Migrated Mockito calls

But couldn’t solve coroutine version conflict between platform libs and MockK.

Iteration 2

Not good

Prompt

There are failing tests

Result

It tried to bring in another version of coroutines and tried to ensure that system JNA wouldn’t be used. This only made things worse.

Conclusion

Honestly my prompting wasn’t the best, but this was supposed to be a simple migration. The agent took a long time running this task and I don’t think it was worth it.

Extending a Rust cli tool using Junie

Implementing a new command to cforge

Iteration 1

Excellent

Prompt

Implement clear command by accomplishing the next tasks:

  1. Create a new file and implement it according to the other commands
  2. Create and verify a tests for clear command
  3. Add the command to the commands.rs

Desing a plan following these steps and present it to me before continuing

Result

Actually one shot the task. Just required minor cleanup (and no plan was ever presented).

Iteration 2

Okay

Prompt

Write documentation for the clear command to the commands.md file and add clear command to the changelog.md file. Increment the minor version

Result

Documentation wasn’t great and required manual tweaking. Way too much unnecessary text.

Conclusion

Really simple change, but it still nailed it.

Implementing a search improvement using Junie

Fuzzier ripgrep file type globbing

Iteration 1

Good

Prompt

Let’s make a modification to FuzzyGrep and FuzzyFinderComponent:

When FuzzyGrep is using ripgrep (rg) command, add a new field to the component. It should be located on the right side of the main search field and share the same container

When in doubt, ask me for clarifications!

Result

The actual field implementation was fine, didn’t remember to say that don’t comment every line (why is this still a thing?)

Iteration 2

Good

Prompt

Remove the unnecessary comments that you’ve added and make the new field around the size of a single word

Result

Comments are gone, but when trying to limit the size, it fucked up the actual field dimensions

TODO: Image here

Implementing preview improvement for Fuzzier using Junie

Up/down navigation for preview

Iteration 1

Excellent

Prompt

Add CTRL + D and CTRL + U keybindings to the main and secondary search field in FuzzyFinderComponent

Result

Nothing to complain about, it also included a working action, which moves half page on the result list.

Even though it overreached, I think the result warrants an excellent grade.

Iteration 2

Excellent

Prompt

Implement the function movePreviewHalfPage for FuzzyFinderComponent

Result

Yup, easy as that.

Iteration 3

Okay

Prompt

Create simple tests for the listeners created at setupCtrlDUShortcuts

Result

Too much complexity, but I did see that coming.

Markdown parsing with Junie

Parsing md files for statistics

Iteration 1

Good

Prompt

Create a stand-alone rust script collect_data.rs that analyzes .md files from content/agents/

Gather the tags from each file and write them to contents/agents/_index.md. The tags are defined in a toml; example below

+++
tags = ['junie','fuzzier','kotlin']
title = 'Implementing a search improvement using Junie'
categories = 'agent-testing'
+++

Result

It collected unique tags from the files and wrote them as tags to the _index.md. Which again is fine, but now what I was looking for.

Iteration 2

Good

Prompt

Instead of collecting and writing unique tags to the content/agents/_index.md collect the amount of tags and display them as a table on the index file

Result

Nothing strange, it did what it was supposed to.

Iteration 3 (new task)

Good

Prompt

Let’s add a new layer of parsing to the collect_data.rs rust script

Updating deprecated calls using Junie

Fix deprecated document listener calls

Iteration 1

Not good

Prompt

Fix TestBenchComponent addDocumentListener call

document.addDocumentListener(listener, project)

The call requires a parent disposable, but it cannot use the project because plugin code shouldn’t do that

Result

It created a new disposable right before creating the listener.

Iteration 2

Not good

Prompt

We shouldn’t create a new disposable to use as a parent disposable right before. That disposable is not handling the lifetime correctly, it is created to just satisfy the function call instead which is not what I want.

Result

It created some convoluted mess of duplicate variables and returned to the deprecated method call.

I rolled back and tried again with a more focused prompt.
