Berkeley Notes

While taking courses at the University of California, Berkeley, I have created detailed notes for many of the classes I have taken. This repository contains those notes in PDF format and the LaTeX source. The PDFs are posted on my website and in online format.

For any typos or fixes, please raise a GitHub issue or create a pull request.

Notes

The notes in this repository are

Testing LaTeX to Markdown Conversion

The online notes are hosted on GitBook, which requires Markdown. The markdown formatted notes are in the gitbook branch. To automatically convert from LaTeX to markdown, I use pandoc. Pandoc can't do the conversion directly, so the pandoc_filter.py script applies a filter to the AST that pandoc creates to modify it for proper conversion. The actual filters are written using my latex-pandoc-filters repository. The actual filters used are defined in pandoc.yaml.

pandoc --to json --from latex+raw_tex --output=<target>.json <target-file>

cat <target>.json | ./pandoc_filter.py > <target>-filtered.json

pandoc --to markdown+pipe_tables-simple_tables-smart --from json --atx-headers
--output=<target>.md <target>-filtered.json

After all the notes are converted into Markdown, each class is in a single document. The last step for formatting on GitBook is to split each note into one note for each section. That is done using create_book.py. This script also creates the SUMMARY.md which GitBook uses as the title page.

GitHub Workflows

When the LaTeX source is updated, the GitBook and the website notes are automatically updated through GitHub workflows. The site-deployment workflow takes the PDFs from the repository and pushes them to the website repository. It is run when a commit is pushed to main. The PDFs which are pushed are listed in website-files.yml and are copied using website-copy.py. The gitbook workflow converts the LaTeX into Markdown and pushes it to the gitbook branch. It is run when a commit is pushed to main. The gitbook-test workflow converts the LaTeX into Markdown and produces a diff on the gitbook branch as well as the Markdown as artifacts for review. It is run on pull-request.
