docs.julialang.org

Built documentation for the Julia language. Source files live in the Julia repository — contribute there.

Branches

• gh-pages — HTML docs served at docs.julialang.org
• assets — PDF manuals for every Julia release, pre-release, and nightly
• master — CI pipeline for building PDFs

PDF pipeline

A daily GitHub Actions workflow builds PDF documentation:

1. Collect versions — compares tags against existing PDFs on the assets branch; skips versions already built or listed in pdf/skip-versions.txt
2. Build in parallel — each missing version + nightly runs as a separate matrix job: downloads the Julia binary, clones the source at the matching tag, and runs make pdf via Documenter.jl
3. Commit — collects built PDFs and pushes to the assets branch

Key files

File	Purpose
pdf/make.jl	Download binaries, build PDFs, commit to assets
pdf/skip-versions.txt	Versions to skip (missing binaries, build failures)
.github/workflows/PDFs.yml	CI workflow (collect → build → commit)
.github/actions/setup-pdf-build/	Composite action for Julia + TeX Live + repo setup

Adding a skip

If a version fails to build, add it to pdf/skip-versions.txt — no code changes needed.
