hologit

What problem does it solve?

Hologit removes the manual, error-prone work of assembling code and generated artifacts across repos by letting you declaratively define virtual branches that combine sources and apply transformations deterministically inside Git.

Core Features & Use Cases

• Holobranches & holomappings: define what content to include and where it should land in an output tree, using layered inclusion rules and topological ordering.
• Holosources: pull content from other repositories and branches (including projected holobranches inside sources), and support workspace self-references.
• Hololenses: transform projected trees via containerized lenses (and optional companion data) with internal (inheritable) and external (branch-specific) execution phases.
• Efficient projection & caching: compute output trees via Git object primitives and cache lens results using deterministic spec hashes to avoid redoing work.

Quick Start

Initialize a hologit workspace and project a holobranch by running: git holo project my-branch.
