fmql

What problem does it solve?

fmql enables treating a directory of Markdown files with YAML frontmatter as a queryable, mutatable data set, removing the need for a fixed schema and letting you discover and manipulate structured metadata across many files.

Core Features & Use Cases

• Query and filter based on frontmatter fields (strings, numbers, dates) across a repository.
• Traverse file references within frontmatter (e.g., blocked_by, belongs_to) to reveal relationships and cycles.
• Bulk-edit frontmatter across matched results, preserving comments and key order while applying changes.

Quick Start

Describe the workspace to learn its fields, then run a query to filter and bulk-edit frontmatter across the directory.
