# Rubrik
Lite text måste man ha.
Och kanske en lista
* LOL
* LAL

En [länk](www.werpers.com) är alltid trevligt

```golang
func hello(i int) string {
    return fmt.Printf("Hello Mr. %d\n", i)
}
```

## Math is also important
What would the world be like without some of this $f(x) = x^2 + 2x + 1$
or even this
$$
\zeta = \frac{1}{N}\sqrt{\sum_{i=1}^N \phi_i(x)}
$$

## Music

X: 22
M:3/4
L:1/8
Q:1/4=100

Nu är frågan hur det fungerar och om det är enkelt att använda

X:1
M:4/4
L:1/8
K: C

Kromatisk skala ser ut på följande sätt;

X:1
M:4/4
L:1/8
K: C
|:F _G G _A A _B B C _D D :|


## Some logic

We also need a table

| A | B | A or B | A and B |
|---|---|--------|---------|
| 0 | 0 | 0      | 0       |
| 0 | 1 | 1      | 0       |
| 1 | 0 | 1      | 0       |
| 1 | 1 | 1      | 1       |

## TODO
Some things need doing
 - [x] Fix bug where there's a nil error when there is no yaml in .md file
 - [x] Fix bug where wdown doesn't work without a template
 - [x] Build the simplest possible markdown commandline utility
 - [x] Add command-line argument parsing
 - [x] Allow template file as an input
 - [ ] Refactor main() to be readable
 - [x] Add possibility to have YAML metadata
 - [ ] Try to add music score
    - [ ] Test using v8go to render the music score server side
    - [ ] Try to create an extension

### Math
 - [ ] Serve MathJax from own server.
 - [ ] Keep investigating if it's possible to use _katex_ with _v8go_ to render math at compile time instead of realying on _MathJax_ to do it in the browser.
 - [ ] Revisit the branch `javascript-experiment` and see if it's possible to get rid of the extra characters rendered by _katex_.

### Code highlighting
 - [ ] Fix the styles so that highlighted block have the same background as non-highlighted blocks
 - [ ] Check of other highlighters use the same kind of coloring idea
 - [ ] Check how to style the code coloring
 - [ ] Switch to CSS-class based code coloring
 - [ ] Configure highlighter

### Community
 - [ ] Fix errors in [goldmark-highlighting README](https://github.com/yuin/goldmark-highlighting)
   - [ ] Faulty import
   - [ ] Extra import chroma/formatters/html
