Description:

pandoccodeattribute 0.2.0

Pandoc filter to add attributes to code blocks based on their classes.

Installation
First install python and python-pip.
Then use pip to install:
pip3 install --user pandoc-code-attribute

Usage

Configuration
By default, this filter won’t add style attributes to prevent undefined
errors.
You can enable it by setting code-attribute field in metadata.
To add attributes to all classes, use:
code-attribute: true
To add attributes to specific classes, use:
code-attribute:
- cpp

Example
This pandoc filter will add attributes to code blocks based on their
classes.
For example, it can be very useful to use different styles for different
language in listings :
---
code-attribute:
- cpp
- python
header-includes: |
\usepackage{listings}
\usepackage[usenames,dvipsnames]{color}

\lstset{ % General settings
numbers=left,
numberstyle=\tiny
}

\lstdefinestyle{cpp}{ % Only for C++
keywordstyle=\color{Green}
}

\lstdefinestyle{python}{ % Only for Python
keywordstyle=\color{Magenta}
}
---

C++:

```cpp
int main(int argc, char *argv[])
{
return 0;
}
```

Python:

```python
def main():
print('Hello')

if __name__ == '__main__':
main()
```
Then compile the example (--listings is needed only for this
example):
pandoc input.md --filter pandoc-code-attribute --listings -o output.pdf
Results:

Command
In general, to use this filter, just add this filter to pandoc command:
pandoc input.md --filter pandoc-code-attribute -o output.pdf
