There was an error in the next method wherein the last value was being shown twice. It has been corrected with the latest commit. I have also downloaded the artifact and tested against it.

Thank you, @nmzaheer. I will take a look soon. Can you tell me something about the expected behavior? Previously (#1467), the stack was named as a ring, now it's a list. Shall I assert the monitor changes compared with IDE 1.x message history behavior?

I had started with the code in #1467 . The discussion there was about renaming the RingList to a different name as Ring implies cyclical behavior. Although HistoryStack was suggested as an alternative, I believed that was wrong. The functionality required traversal through the data structure and hence HistoryList was better name,

The expected behavior should be as in Arduino 1.x . Let me know once you have tested it.

Is the team getting close to a release?

I will ensure this feature is part of the next patch release of IDE2. We plan to roll out the next version this month. Please bear with us.

@dwightfowler-cd, if you do not plan to do follow-ups on #1467, please close it. Thanks for keeping the repo clean ❤️

@kittaakos Did you have a chance to test the behaviour? Do you have any feedback for me?

It's working great. Thank you for your contribution. I believe the logic can be simplified. Let's remove the unnecessary state from the HistoryList. See my proposal here. What do you think?

Please give it a try. If you like it, you can cherry-pick the changes, or you can add my fork to your remotes and pull in the changes.

Thank you for testing. Your implementation looks much neater and simpler than what I had submitted.

I am testing your implementation of HistoryList with this code. However, it skips the first entry when next method is run. I will have to correct the code accordingly.

I'll get back to you with the changes.

Edit
I think the below code implementation is more apt since the previous method should not return an empty string when it has reached the beginning of the list. In IDE 1.x, once the index reaches the beginning of the list, the first element is returned always.

  previous(): string {
    if (this.index === -1) {
      this.index = this.items.length - 1;
      return this.items[this.index];
    }
    if (this.hasPrevious) {
      return this.items[--this.index];
    }
    return this.items[this.index];
  }

Looking forward to your feedback.
