I think this is a great idea, and I've wondered about something like this before.

I do find it sad though that the opening description has to be:

> Two agents edit different functions in the same file? Clean merge.

Why does EVERYTHING has to be geared towards agents? Humans can use this too. Why not just "two commits contain edits for different functions in the same file?"

This was also my first thought when I checked the website. I was interested in the general merge approach, and that it works with LLMs and agents fine, but that's secondary. Nowadays every product must be in-your-face AI-first somehow, often to the extent that it de-emphasizes why the product exists in the first place, its core competency and distinguishing features pushed below the fold by screaming "It supports AI" headlines. It saddens me. That something supports AI is nothing special anymore, an expected feature. Just mention it like that, in the product highlight box next to where it mentions that it supports Github or similar nothing-special features.

Automated process run into race conditions more often due to their frequency. Humans can do that too, but are less likely to in practice both due to lower frequency and because they carry more awareness of global context that isn't captured in systems that aren't checking for it. The ability of your brain to read and take as context all the pull requests open in a repo that might affect your work.

Moving forward one can expect the most amount of code to be generated by agents, so it makes sense to optimise for that use case.

(Note that i’m not saying it’s good or bad)

How do the agent and human use cases meaningfully differ here, though?

I'm pretty sure GP's complaint is about the prose description, rather than the actual functionality.

At this point I just ask an LLM to resolve conflicts, works most of the time. An LLM can not only understand the language, it can also understand the intent behind both changes, which leads to much better results

Thank you very much for stating it all up-front.

First image I see should be a difference of how the merges work.

Thanks a lot for this feedback, you are right, but I actually had a page about the merge algorithm more in depth, maybe you will love it.

Could you link to it? I couldn’t find it on your site.

The AI thougth it's better to just show the result in a stupid manner. I expect the software AND the website are mostly AI generated.

How do I use it in my normal flow?

Edit: the readme on github explains quite well

Without having looked into how Weave works, it sounds similar to Mergiraf: https://mergiraf.org/

There's a benchmark on the site that compares with mergiraf.

I tried to read this, and what the tool works, but this is so much text with little context. Looks like AI fluff. It sounds pretty straight-forward, so this should be a single page with a few paragraphs only.

Does this _need_ to be language specific, semantic and smart? Just a word-based diff would be so much better than a line-based diff.

If it is worth trying out, it is worth writing the README for.

Yeah you can find the readme on the github repository.

This tool does not work. I wanted it to work. I wanted to automate merges with AI supervision. No dice. Silent corruption that wouldn't go away no matter how many issues I filed. Unacceptable. Had to disable it. https://github.com/Ataraxy-Labs/weave/issues?q=is%3Aissue%20... Be warned.

I am sorry about your experience igra, but to be fair, yeah there are some failure cases but I love to receive any feedback that you think can improve it and make it a more generalized solution.

Pretty cool. I always thought merges should happen by comparing the AST and not lines

How does it compare to SemanticDiff extension?

I'm working on an online diff tool (https://codeinput.com/products/merge-conflicts) and recently added a mergiraf integration. Basically, the tool loads your git merge but uses mergiraf as the resolution driver. Then add these auto-resolved files to the editor instead of auto-resolving directly.

I also tried out weave, but apart from TypeScript, I haven't found any cases where it actually outperforms mergiraf (I run a bot that watches for new merge conflicts on GitHub, so I've got a steady stream of conflicts to test against).

I reached out a couple months ago on Reddit, but I don't think we ever landed on a time to talk. Would be interested to re-connect again.

Too bad Trump hijacked the meaning of the word "weave" to mean senile "sunsetting" and rambling incoherently from unrelated topic to topic, swerving between conversational lanes and colliding with facts and laws and decency like a sleepy angry drunk driver off his meds.

how does it fare on organisation repos ? Its quite tricky to make it work on org plans where git based merge goes through a lot of code scannings and stuffs i guess. Curious to know about that

Good question. Weave is a standard git merge driver, so it slots into the existing flow rather than replacing it. You wire it up in .gitattributes, and it only changes the 3-way conflict-resolution step that git already runs. The output is a normal merged tree, so everything an org layers on top still runs unchanged: branch protection, required status checks, code scanning, CI. It isn't bypassing any of that. It just resolves conflicts by entity structure (functions, classes, methods) instead of line hunks, then hands a regular file back to git.
