# 설치 가이드

1. 코드 내려받기

git clone https://github.com/susam/muboard

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd muboard

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

<!DOCTYPE html><script src="https://cdn.jsdelivr.net/npm/muboard@0.5.2"></script><textarea>

이 명령어를 터미널에 그대로 입력해 실행하세요.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

3. Make

보통

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Make Linux/macOS는 보통 기본 설치되어 있습니다. Windows는 별도 설치(예: MSYS2, WSL)가 필요합니다.

make

생성된 빌드 설정을 바탕으로 실제 컴파일을 진행해 실행 파일을 만듭니다.

✅ 에러 없이 끝나면 성공입니다. 생성된 실행 파일을 직접 실행해보세요.

Muboard
=======

[Muboard][Muboard URL] is a tiny utility that runs a mathematics
display board as a web page. Muboard lets you quickly scribble
mathematics snippets using Markdown and LaTeX while presenting your
desktop screen to others during real-world or virtual meetings.

Get Started
-----------

To get started with using Muboard, [click here][Muboard URL] and start
typing Markdown + LaTeX input at the text field at the bottom.

Here is an example screenshot that shows how Muboard with some content
looks like:

<div align="center">

</div>

Distributable Boards
--------------------

Muboard can be used to create distributable boards. To try it out,
copy and paste the code below into an HTML file with `.html`
extension:

```html
<!DOCTYPE html><script src="https://cdn.jsdelivr.net/npm/muboard@0.5.2"></script><textarea>

# The Möbius function

For any positive integer $ n $, the Möbius function $ \mu(n) $ is
defined as follows:

$$ \mu(1) = 1; $$

If $ n > 1, $ write $ n = p_1^{a_1} \dots p_k^{a_k} $ (prime
factorization). Then

\begin{align*}
  \mu(n) & = (-1)^k \text{ if } a_1 = a_2 = \dots = a_k = 1, \\
  \mu(n) & = 0 \text{ otherwise}.
\end{align*}

If $ n \ge 1, $ we have

$$
  \sum_{d \mid n} \mu(d) =
  \begin{cases}
    1 & \text{ if } n = 1, \\
    0 & \text{ if } n > 1.
  \end{cases}
$$
```

Now open this file with a web browser. This is a self-rendering
distributable board file. It renders itself to look like this:
[mu.html][Demo URL].

### Valid HTML5

The code snippet in the previous section shows how we can create a
self-rendering document with a single line of HTML code but this
brevity comes at the cost of standard conformance. For example, the
required `<title>` element is missing from the code. Further the
`<textarea>` element is not closed. Despite the missing tags, this
example works just fine because all web browsers follow the
[robustness principle][robustness].

For the sake of completeness and correctness, here is a minimal but
complete and valid HTML example:
[mu-html5.html](https://susam.github.io/muboard/mu-html5.html)
([source](examples/mu-html5.html)). It has a few more lines of code
to ensure that this HTML5 code validates successfully at
[validator.w3.org][validator]. In case you are wondering, a valid
HTML5 document does not require explicit `<head>`, `<body>`, or the
closing `</html>` tags, so they have been omitted for the sake of
brevity while maintaining completeness and correctness in this
example.

Features
--------

* Runs in a web browser.
* Keyboard driven user interface.
* Vertical splits.
* Input is just LaTeX, Markdown, and HTML. Avoids any new syntax.
* Conforms to CommonMark specification of Markdown.
* Conforms to GitHub Flavored Markdown (GFM), a strict superset of
  CommonMark.
* Supports a [subset of LaTeX][macros] using MathJax.
* Supports creating self-rendering distributable boards with a single
  line of HTML.
* Supports editing commands such as `,i`, `,d`, `,align*`, etc. to
  automatically insert LaTeX delimiters for inline mathematics,
  display mathematics, align environment, etc. (Type `,help` in the
  board input to see a complete list of supported commands.)
* Support for saving/loading snippets to/from browser's local storage.
* Not a [WYSIWYG][wysiwyg] tool.
* Not a collaborative editing tool.

Why?
----

Muboard was created originally for [analytic number theory club
meetings][meet] that I used to host in 2021. During the meetings, I
needed a place to type out mathematics formulas and render them
quickly. I chose to write a tiny non-WSYIWYG tool because I prefer
such tools. It also helps in keeping the LaTeX snippets in an HTML
file that can render itself using JavaScript.

The name *Muboard* is a reference to the Möbius function *μ(n)* which
was the first function definition we discussed using this tool.
