# Mark's Handout Library

This is a collection of math circle handouts that I (and many others) have written. \
They are used regularly at the [ORMC].

For more information, visit [betalupi.com/handouts]. \
The latest version of each handout is available at that page.

## License

Unless otherwise stated, all documents in this repository are licensed under [CC BY-NC-SA 4.0]. \
Each document has its own authors. See `meta.toml` in each project directory for details.

By submitting or editing a handout in this repository, you agree to release it under this license.

## 🛠️ Contributing

If you want to use one of these handouts for a class, see [betalupi.com/handouts]. \
You only need to read this section if you want to edit these handouts.

### Setup

Use git to clone this repository, then open the root folder in [vscode] or [vscodium].

We use the [latex-workshop] and [tinymist] extensions. Install them before continuing.
[`./vscode/settings.json`](./vscode/settings.json) will automatically configure them to work with this repository. \
You may need to install texlive and typst:

-   If you use Linux, you'll figure it out.
-   On macos, use [homebrew]: \
     `brew install texlive typst typstyle`
-   On Windows, I don't know. I may write instructions later.

### Editing

This repository is organized as follows:

-   All handouts are in [`./src`](./src). \
    Every handout is stored in its own directory, even if it only consists of one file. \
    Handouts are organized by group (see [betalupi.com/handouts] for details).

-   Packages are stored in [`./lib`](./lib) \
    You shouldn't need to modify any library files, but you may want to read them to see how they work.

-   [`./tools`](./tools) contains build scripts, [`./.github`](./.github) configures automation. \
    You can ignore everything in these directories.

All handouts in this repository are based on `handout.cls` or `handout@0.1.0`.

-   If you're using Typst (preferred), read [`docs-typst.md`](./docs-typst.md)
-   If you're still using LaTeX, read [`docs-latex.md`](./docs-latex.md).

### Metadata

Every handout directory should contain a file called `meta.toml` with the following contents:

```toml
# This is a sample `meta.toml`.
# A copy of this file should exist in every handout directory.
# All keys are required.

[metadata]
title = "title of this handout"


[publish]
# Should we publish this handout?
# If `false`, no part of this handout is published.
handout = true

# Should we publish an "instructor's" version of this handout?
# This key has no effect if `publish.handout` is false.
#
# If `true`, publish a second version of this handout with solutions.
# Set this to `false` if solutions haven't been written.
solutions = true
```

## 💾 Out-of-band compilation

If you want to compile these handouts _without_ this repository (e.g, on [Overleaf] or [Typst.app]), do the following: \
_(I do not recommend this. The default toolchain makes it easier to share improvements to these handouts.)_

### For LaTeX:

1. Get the handout's directory (i.e, download the whole repo as a zip and extract the folder you want.)
2. Download [`./resources/handout.cls`](./resources/handout.cls)
3. Put this `handout.cls` in the same directory as the handout.
4. Fix the include path at the top of `main.tex`:

You'll need to replace

```latex
\documentclass[
	...
]{../../../lib/tex/handout}
```

with

```latex
\documentclass[
	...
]{handout}
```

5. Make a new overleaf project with the resulting directory.
6. **Do not use pdflatex**, it misbehaves with `handout`. Tell Overleaf to use XeLaTeX.

### For Typst:

Out-of-band typst compilation isn't supported. Clone the repository and use vscode. \
This is because typst can't import packages from a relative path.

If you _really_ want it, standalone typst compilation _is_ possible. \
Follow the LaTeX instructions, but fix `handout@0.1.0` instead of `handout`. \
You'll figure it out.
