… from spec diff This enables a new workflow for creating OpenAPI overrides: 1. Copy your OpenAPI spec 2. Edit the copy directly (add x-fern-* extensions, etc.) 3. Run `fern overrides compare original.yaml modified.yaml` 4. Get a clean overrides file with only the differences Features: - Supports both JSON and YAML input specs (can mix and match) - Always outputs YAML - Optional `--output` / `-o` flag to specify output path - Defaults to writing `<original>-overrides.yml` alongside the original file Also reorganizes overrides commands under `fern overrides`: - `fern overrides compare` - new command - `fern overrides write` - moved from `fern write-overrides` - `fern write-overrides` - deprecated alias (hidden, shows warning) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
