# Introduction

- I added this feature to my markdown parsing but would like this feature to be part of the standard itself
- I also noticed many variations of this, especially for mathematical formulas

# Traditional fenced code

**markdown** :

```
```ruby
1+1
```
```

**html representation** :

```
1+1
```

# Evaluated fenced code

Sometimes we want to evaluate the code given without another tool, but more generally make it possible for more advanced parsers to be. Here is a proposal :

**markdown**:

```
```eval[ruby]
1+1
```
```

**html representation**:

```
2
```

# The same applies for Graphs & Mathematical formulas

This should proposal should also take into consideration code that renders : a graph or a mathematical formula e.g. :

**markdown** :

```
```render[dot]
a->b
```
```
