Src2Markdown

Description

SrctoMarkdown.py takes a script written in python, perl, java, javascript, R or bash and generates a markdown document with comments processed as markdown text, and code embedded in markdown code tags.

The output file is then converted into html, pdf, and other output formats supported by Pandoc.

Comments on markdown style

Perl, Bash, R

If you want to add a markdown comment, you have to use the #' pattern. It tells ScrtoMarkdown that comments with this pattern at the beginning of each line will be processed as markdown text.

Example:

#' # This is a title
#'
#' This is a comment in **markdown style**. *This text will be in italics!*.
#'
#' This is another paragraph. Still in markdown format.
#'
#' ## This is a subtitle
#' 
#' Last paragraph.
#'  

print "Hello world in Perl!";

# This is a normal comment in Perl and will not be considered as markdown text.

Python

Python uses single-line and multiple-line comments.

Single-line comments

For single-line comments, same rules mentioned for Perl, Bash and R.

Multiple-line comments

Multiple-line comments are possible in Python using the ''' pattern around text.
In order to use markdown comments, use '''# and #''' tags around text.

Example:

'''#
# Outstanding title

This is a text formatted in **markdown**.
This text embedded in special tags to indicate it will be
processed as markdown text.


Fancy table:

| X | Y |
|:-:|--:|
| 1 | 2 |
| 3 | 4 |
| 5 | 8 |


#'''

print("This is a hello world in Python 3!!")

#' > Another markdown comment

Java and Javascript

Java and Javascript share the same way to make comments.

Single-line comments

Use //' pattern.

Example:

//' This is a comment that will be processed as markdown text.
//' Another comment.

document.write("You can't see this!");

// This is a single line comment (not processed as markdown).

Multiple-line comments

Use /** and **/ tags around text.

Example:

/**
# Sum function
**Overview**: Returns the sum of two numbers
Parameters:
- a: Numeric variable
- b: Numeric variable
## Example
result=sum(5, 10)
**/


function sum(a, b) {
    return a + b;
}

Use /** and **/ tags alone in single lines! Do not include parts of markdown text in the same line.

Example:

/** # Sum function
**Overview**: Returns the sum of two numbers
Parameters:
- a: Numeric variable
- b: Numeric variable
## Example
result=sum(5, 10) **/

Notes

This program is humbly inspired by the awesome work on Knitr by Yihui Xie and Rmarkdown by JJ Allaire.
