PaperForge Public API

Compatibility policy

PaperForge follows Semantic Versioning. Beginning with 1.0.0, documented functions, structs, options, and return values in the modules below are covered by the 1.x compatibility contract:

• PaperForge
• PaperForge.Flow
• PaperForge.Page
• PaperForge.PageContext
• PaperForge.Color
• PaperForge.Document
• PaperForge.Image
• PaperForge.Metadata
• Public exception modules

Modules whose @moduledoc is false are implementation details. Their names, data structures, and functions may change in a minor release.

Deprecations

A public API is deprecated before removal. Deprecations include an @deprecated message naming the replacement and remain available throughout the current major release. Removal happens only in the next major version.

Output compatibility

Patch releases preserve document semantics but do not promise identical bytes across different PaperForge versions. Identical inputs within the same version produce deterministic bytes when callers provide deterministic metadata.

Supported runtime contract

The supported Elixir and OTP versions are declared in mix.exs and CI. A future release may drop an end-of-life runtime only in a minor release and will record that change in the changelog.

Optional external validation

PaperForge does not shell out while generating PDFs. Development and CI may run pdfinfo, qpdf --check, and VeraPDF when those tools are installed.
