weave — Merge without conflicts

weave

Entity-level semantic merge driver for Git. Two agents edit different functions in the same file? Clean merge. Every time.

git merge # Two agents edited different functions

$ git merge feature-b CONFLICT (content): Merge conflict in src/lib.ts Automatic merge failed.

# Git sees overlapping lines. # The functions don't actually overlap. weave # Same merge, with weave configured

$ git merge feature-b weave [src/lib.ts]: 2 entities matched, 2 modified, 0 conflicts Merge made by the 'ort' strategy.

# Different functions = no conflict.
