I've posted a GitHub Discussion talking about the future of fern: https://github.com/daboross/fern/discussions/147
If you've ever used fern, or you do today, I'd love input!
colored crate + custom global allocatorOne of our downstream dependencies, atty, through colored, has an unsoundness issue: .
This shows up in one situation: if you're using colored 0.1.0 and a custom global allocator.
Upgrade to fern 0.7.0 to fix.
There's one thing I need right now, more than anything else: input on what fern does well, and what it should keep doing well. See Project Direction.
Besides that, I'm open to PRs! I'll probably review promptly, and I'm always open to being nudged if I don't.
For small PRs, I'll mark anything I need changed in a review, and work with you on that.
For larger PRs, I reserve the right to pull in your commits as they are, then fix things I want to be different myself. In a workplace, I'd try to never do this - but this is a hobby project for me, and I'd rather be overly particular about fern's implementation than be reasonable.
This is a change from my previous policy.
