title: HelloThere
|
|
|
|
This is a TiddlyWiki plugin for mathematical typesetting based on KaTeX from Khan Academy.
|
|
|
|
It is completely self-contained, and doesn't need an Internet connection in order to work. It works both in the browser and under Node.js.
|
|
|
|
! Installation
|
|
|
|
To add the plugin to your own TiddlyWiki5, just drag this link to the browser window:
|
|
|
|
[[$:/plugins/tiddlywiki/katex]]

|
! Using KaTeX
|
|
|
|
The usual way to include ~LaTeX is to use `$$`, as shown in the examples below.
|
|
|
|
The underlying KaTeX widget is provided under the name `<$latex>` and is also available under the alias `<$katex>`. It's better to use the generic `<$latex>` name unless you are running multiple ~LaTeX plugins and wish to specifically target KaTeX.
|
|
|
|
! Examples
|
|
|
|
These examples are taken from http://khan.github.io/KaTeX/
|
|
|
|
!! Example 1
|
|
|
|
If the text between `$$` contains newlines it will rendered in display mode:
|
|
|
|
```
|
|
$$
|
|
f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi
|
|
$$
|
|
```
|
|
|
|
$$
|
|
f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi
|
|
$$
|
|
|
|
!! Example 2
|
|
|
|
```
|
|
$$
|
|
\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }
|
|
$$
|
|
```
|
|
|
|
$$
|
|
\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }
|
|
$$
|
|
|
|
|
|
!! Example 3
|
|
|
|
```
|
|
$$
|
|
1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots = \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1.
|
|
$$
|
|
```
|
|
|
|
$$
|
|
1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots = \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1.
|
|
$$
|
|
|
|
!! Widget Example
|
|
|
|
For more flexibility the KaTeX widget can also be used via the full widget syntax:
|
|
|
|
```
|
|
<$latex text="f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi" displayMode="true"></$latex>
|
|
```
|
|
|
|
<$latex text="f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi" displayMode="true"></$latex>
|
|
|
|
! Error Handling
|
|
|
|
Any LaTeX syntax errors are flagged with the problematic syntax highlighted. For example:
|
|
|
|
```
|
|
$$ f(x) = \int_{-\infty}^\infinity\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi $$
|
|
```
|
|
|
|
$$ f(x) = \int_{-\infty}^\infinity\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi $$
