#+TITLE:    :tools pdf
#+SUBTITLE: Emacs, your next PDF reader
#+CREATED:  February 06, 2018
#+SINCE:    21.12.0

* Description :unfold:
This module improves support for reading and interacting with PDF files in
Emacs.

It uses [[doom-package:][pdf-tools]], which is a replacement for the built-in ~doc-view-mode~ for
PDF files. The key difference being pages are not pre-rendered, but instead
rendered on-demand and stored in memory; a much faster approach, especially for
larger PDFs.

Displaying PDF files is just one function of [[doom-package:][pdf-tools]]. See [[https://github.com/politza/pdf-tools][its project website]]
for details and videos.

* Installation
[[id:01cffea4-3329-45e2-a892-95a384ab2338][Enable this module in your ~doom!~ block.]]

This module requires =epdfinfo=, a program the the [[doom-package:][pdf-tools]] plugin will build
automatically when you open your first pdf file, unless you're on Windows.
Windows users must build it themselves.

You can (re)build =epdfinfo= yourself with ~M-x pdf-tools-install~.

** Building =epdfinfo= on Windows
1. [[https://www.msys2.org/][Install MSYS2]] and update the package database and core packages using the
   instructions provided.

2. Update and install dependencies, skipping any you already have:
   #+begin_src sh
   pacman -Syu
   pacman -S base-devel
   pacman -S mingw-w64-x86_64-toolchain
   pacman -S mingw-w64-x86_64-zlib
   pacman -S mingw-w64-x86_64-libpng
   pacman -S mingw-w64-x86_64-poppler
   pacman -S mingw-w64-x86_64-imagemagick
   #+end_src

3. Install PDF tools in Emacs, but do not try to compile the server. Instead,
   get a separate copy of the source somewhere else:
   #+begin_src sh
   git clone https://github.com/politza/pdf-tools
   #+end_src

4. Open mingw64 shell (Note: You must use mingw64.exe and not msys2.exe)

5. Compile pdf-tools:
   #+begin_src sh
   # Cask requires python2 (important: not 3!)
   pacman -S python2

   # Make the mingw-shell aware of your python installation. Adjust the path if
   # Emacs is installed elsewhere!
   export PATH="/c/Program Files (x86)/Emacs/bin/:$PATH"

   # Cask needs to know where git.exe is; change this path if git is installed
   # elsewhere!
   export PATH="/c/Program Files/Git/bin:$PATH"

   # Install cask. Certificate errors can be ignored with (unsafe) -k option.
   curl -fsSL https://raw.githubusercontent.com/cask/cask/master/go | python

   # Make sure the build process can see cask
   export PATH="$HOME/.cask/bin:$PATH"

   cd /path/to/pdf-tools
   make -s
   #+end_src

6. This should produce a file =server/epdfinfo.exe=. Copy this file into the
   =$HOME/.emacs.d/.local/straight/build/pdf-tools/=.

7. Start Emacs.

8. Open a pdf file (or run ~M-x pdf-tools-install~)

9. Test it out: ~M-x pdf-info-check-epdfinfo~
