Markdown macros - embed program outputs in markdown

Let's say I have a markdown file test.md which looks like this:

# Hello, World

This is _just markdown_.

## Current date is:

<!-- <macro exec="date +%x"> -->
<!-- </macro> -->

## Current time is:

<!-- <macro exec="date +%R"> -->
<!-- </macro> -->

If I pipe it through markmac, the macro commands will be executed and their STDOUT will be embedded between <macro> and </macro>.

$ cat test.md | markmac
# Hello, World

This is _just markdown_.

## Current date is:

<!-- <macro exec="date +%x"> -->
10/07/2020
<!-- </macro> -->

## Current time is:

<!-- <macro exec="date +%R"> -->
15:48
<!-- </macro> -->

markmac searches for the <macro> directives inside your markdown file, executes the command in exec and substitutes the contents between <macro> and </macro> with STDOUT.

Installation

This program is distributed via npm, so it can be installed through yarn or npm or any other supporting client:
