README.md

This Git Repository is a PDF

This repository contains the LATEX source of the PDF, as well as all of the scripts necessary to rebuild the polyglot.

Building the Polyglot

If you cloned this repository directly from the PDF,

$ git clone PDFGitPolyglot.pdf PDFGitPolyglot
Cloning into 'PDFGitPolyglot'...
Receiving objects: 100% (174/174), 103.48 KiB | 0 bytes/s, done.
Resolving deltas: 100% (100/100), done.

then you will need to do some cleanup before running make:

git checkout master && git branch -d PolyglotBranch

After that, or if you cloned the repo from elsewhere (e.g., GitHub), then you will be able to run make, which will automatically build PDFGitPolyglot.pdf from the document contained in article.tex.

The first time you run make, the sources to a patched version of Git will be downloaded and compiled. This can be time consuming, so I suggest you use make -j8, or whatever is appropriate for your system.

Dependencies

  • a relatively full install of a TEX distro, such as TeX Live
  • autoconf and a C99 compiler for compiling git; I've found that git likes clang more than gcc
  • all of git's sourcecode dependencies (openssl, curl, gettext, &c.)
  • Python 2.7
  • bash
  • ImageMagick
  • qpdf, used by the verify_xrefs.py script for sanity checking; this dependency can be removed by commenting out the call to verify_xrefs.py in the Makefile

Caveats

The polyglot will fail to build if your document has any PDF objects (e.g., images) that are larger than 0xFFFF bytes. Read the article for more details.
