Preserving code and table format pandoc markdown to pandoc markdown

[lamyergeier]

Motivation

• To convert all inline link to reference link while preserving other elements of markdown format, that I follow:
  • atx headers,
  • pipe style table,
  • backtick block code with name of language (without curly braces),
  • content never wrapped

Preface

• I have gone through this closed issue:
  • Pipe Tables written by pandoc cannot be written as pipe tables again · Issue #3171 · jgm/pandoc,
  • Tables not preserved in Markdown -> Markdown conversion · Issue #740 · jgm/pandoc.
• But, I am unable to resolve a similar issue as follows.
• I am reporting it here, as I think the Pipe Table issue is a bug.

Input Pandoc Markdown - Data.md

Issue

1. How can I preserve the block code format (i.e. c instead of {.c}) while I have disabled fenced_code_attributes?
2. How can I prevents backticks of fenced code from vanishing?
3. How can I make sure that the table format is of pipe style as output?

Reference

• Pandoc - Pandoc User’s Guide#
  • If the fenced_code_attributes extension is disabled, but input contains class attribute(s) for the code block, the first class attribute will be printed after the opening fence as a bare word.

That's actually three separate things you're asking. Please use the pandoc-discuss mailing list for questions like this in the future.

What you want is to change the output of pandoc, so you should change the extensions on the output format (-t markdown), not the input format (-f markdown...).

1. use -t markdown-fenced_code_attributes
2. not sure what you mean.
3. To get pipe-tables with your input, simply use -t markdown-simple_tables
