Smart Code Block Converter Command

[polyglot-jones]

I plan to write a command where you select one or more lines and then invoke the command to have it interpret the content and transform it into an AsciiDoc block.

Use Case 1: quotations

If every line follows the pattern of: text enclosed in double-quotes (or typographical ones) immediately followed by an em-dash, double n-dashes, or a tilde, followed by anything that begins with a letter, then each line is converted into a quotation block.

Use Case 2: Comment Blocks

// a whole

// bunch
// of comments

becomes

////
a whole

bunch
of comments

Use Case 3: source code

If it can determine that the selected lines are some sort of source code, then it'll enclose it as a source code block.

[source, bash]
-------------------------------------------------------------------------------
sudo apt update
-------------------------------------------------------------------------------

• If there is a she-bang to go by (#!/usr/bin/env bash), it's obvious.
• If there are lines that start with sudo then it's a bash script.
• If there are lines that start with import or from ... import then it's Python.
• etc.

In all cases, it would unindent the block if every line begins with white space.
