@ractive

@ractive is a small, developer-focused publisher whose single public tool, hyalo, turns folders of Markdown notes into queryable knowledge bases. Written in Go and distributed as a lightweight CLI, hyalo reads every `.md` file that contains YAML front-matter, indexes the metadata, and exposes fast text search, tag filtering, and link-graph inspection commands. Academics use it to navigate research libraries, technical writers to verify cross-references across handbooks, and hobbyists to surface hidden connections in personal wikis. Because the utility leaves the original files untouched and writes no proprietary database, it fits naturally into Git-based or cloud-synced workflows; users can revision-control their content while still enjoying the speed of an in-memory index. Optional JSON export and shell-completion scripts let hyalo feed data into static-site generators, dashboard widgets, or CI documentation checks. The open-source repository welcomes pull requests that extend parsers, themes, or output formats, so the feature set evolves with the community’s note-taking conventions. Hyalo is available for free on get.nero.com, where the latest Windows build is delivered through the winget channel, supports batch installation alongside other utilities, and always pulls the freshest release.
