Tex4Tum

Interactive Knowledge Platform

TeX4TUM is an online library of small articles of the topics:

• Math
• Physics
• Electrical Engineering
• Information Theory

Check out the demo: https://www.tex4tum.de

The articles are based on the cheat sheets from www.latex4ei.de

Features

• Interactive Content: Display only the categories you need
• Interactive Graphs: Play with graphs for better understanding
• Interactive Math: Directly calculate an equation while reading
• Lunar JS Search: Find articles really fast
• Abbreviations: Hover your mouse over an abbreviation to see the full name

Internal Working

Markdown (MD) files are converted in three steps

1. Preprocess MD to MD with Pandoc
2. Cleanup MD with SED
3. Converting MD to HTML using Matieral mkDocs

Contribution

If you want to contribute articles, clone the repo and test the build process locally.

Setup

Setup and install dependencies locally

make setup

or use our Dockerfile container

docker-compose up       # Now you can access the website at localhost:8000

Build and Test

# Build
make

# Serve with hot reload at localhost:8000
make run

# Serve with hot reload at localhost:8000 including _draft articles
# No acronyms replacement to improve build time
make draft

pre-commit git hooks

We use pre-commit to manage our git pre-commit hooks. pre-commit is automatically installed from requirements.txt. To set it up, call

git config --unset-all core.hooksPath  # may fail if you don't have any hooks set, but that's ok
pre-commit install --overwrite

Usage

With pre-commit, you don't use your linters/formatters directly anymore, but through pre-commit:

pre-commit run --file path/to/file1.cpp tools/second_file.py  # run on specific file(s)
pre-commit run --all-files  # run on all files tracked by git
pre-commit run --from-ref origin/master --to-ref HEAD  # run on all files changed on current branch, compared to master
pre-commit run <hook_id> --file <path_to_file>  # run specific hook on specific file

Folder Overview

• _article: the content source files in Markdown (input)
• overrides: Additional files for Matieral mkDocs
• _plugins: Our Ruby scripts for processing Markdown source files
• _sass: Bootstrap SASS and custom CSS3 files
• docs: The rendered website in HTML (output)
• res: static files such as images and code
• tmp: temporary build files

Future Plans

• Auto generated TOC for folders
• Generate internal links to terms used in the text
• Solve math equations (Math JS)
• Topic Concepts
• Summary/Concept boxes (e.g. for buses: speed, wires, range)
• consistent JS framework for interactive content
• Improved search: Sorting results, reaction to no results (forward to wolfram alpha)
• More content
