Firstly, touch up my blog articles to be suitable for PDF

Do this by automating vim with emacs.

Find blog articles without LATEX_HEADER

1

cd $HOME/blog/posts; find . -name '*.org' | eipct -x -E "! grep -q LATEX_HEADER" | eipct -x grep -q HUGO_BASE | head -n 5
./aws-services.org
./rat.org
./music-playlists-in-emacs-lisp.org
./minor-mode-wrappers-for-shell-commands.org
./review-of-introduction-rust-by-example.org

Automate vim with emacs keyboard macros

I want to add the latex header to all the blog posts without one.

This is the header I’d like to add:

2

#+LATEX_HEADER: \usepackage[margin=0.5in]{geometry}
#+OPTIONS: toc:nil

The find script will start vim with the output of a find command.

1

nsfa -E "find . -name \"*.org\" | eipct -x -E \"! grep -q LATEX_HEADER\" | eipct -x grep -q HUGO_BASE | v"

/tmp/nsfa-find-name-org-eipct-x-e-grep-q-latex-hea.sh

Start the find script inside emacs.

This puts vim inside emacs with the results.

Create a pdf for every blog post

Make the sort-blog-posts-by-date script

This script scrapes dates from the contents of each blog post using rosie lang and then generates a JSON file using jq, sorted by the date.

The jq input function is used to load lines two at a time into individual json objects.

Make the e-org-latex-export-to-pdf script

This script automates emacs using tcl/expect to open a blog post and then export latex code.

The tex file is then converted to a pdf.
