pandoc-pyrun 1.0.2

Pandoc filter to run python code blocks

pandoc_pyrun

Pandoc_pyrun is a pandoc filter used to execute Python code embedded in Markdown CodeBlocks.
The result of the execution of the Python code is displayed in the produced documents, for example in PDF or HTML format. Images produced by the turtle and mathplotlib Python libraries can also be included.
Options allow to display the Python code and / or the result of its execution.

\

Usage

An interactive alive console takes the input code, compiles it and displays it to the specific type given, like PDF or Markdown. It can also manage turtle or mathplotlib codes by generating the images, saving them in the current directory and adding the markdow line to incorporate them in the final file. Code has to be trusted ; which means that the code is not verified before any execution, the role of this filter is just to execute the code, not to make sure that it is safe to execute it.
To use this filter, you can execute this command template :

pandoc INPUT_FILE -o OUTPUT_FILE -t OUTPUT_FORMAT  -F pandoc_pyrun

Example :

pandoc hello.md -F pandoc_pyrun -t pdf -o hello_converted.pdf

• This can be used to convert into any text pandoc supported format.
• The only expected source is Markdown language.

\

Installation

pandoc_pyrun requires Python language.
To install the filter, follow the instructions below :

1. Install Pandoc on your device with this link
2. (Optional) Install LaTeX to transform your markdown into pdf with this link
3. Install Ghostscript for plot and turtle figures with this link
   • NOTE : In your PATH variable, make sure you have the bin/ folder of Ghostscript added, otherwise it won't work.
4. Update your pip with python -m pip install --upgrade pip
5. Install this filter with pip install pandoc-pyrun

How to use it

On the top of your document, you'll be able to define global variables for the pandoc_pyrun filter.
NOTE : the classes' names and values can be written in both ways : lower case and upper case.

pandoc_pyrun_out: OUT
pandoc_pyrun_mode: MODE
pandoc_pyrun_type: TYPE
---

Here is a sample of how a CodeBlock has to be written ; you can also put values (other than defined above) for any pandoc_pyrun classes in the {}.
Instead of .py or .python, you can also write .pandocPyrun.

    ```{.py[thon] out=OUT type=TYPE scope=SCOPE file=FILE}
    #Here you enter your code
    ```

\

The list of possible values for the above parameters can be found in the overview table of the reference_manual.
A complete use of this filter is available in the tutorial.

\

NB :

• Only CodeBlock can be read with this filter.
• If you don't want to let the filter compile your code, add a .pyrunPass between the {} explained below.
• The main goal of its utilisation is to produce, for a code block, its text and/or its execution's result by a Python interpreter.

\

Examples

Let's take the following document content input.md.

    ```{.python out=NONE}
    def for_all(lst):
        return not False in lst
    ```

    ```{.python out=ALL}
    for_all([])
    for_all((True, True, True))
    for_all((True, False, True))
    ```

Here we have forced the out values but the others are set as [default] as indicated in the table above.
Now just execute pandoc -o output.md input.md -F pandoc_pyrun and then you'll get :

    ::: {.pyrun}
    ::: {.in}
    ``` {.python .pyrunPass}
    for_all([])
    for_all((True, True, True))
    for_all((True, False, True))
    ```
    :::

    ::: {.out}
    ``` {.python .pyrunPass}
    True
    True
    False
    ```
    :::
    :::
