⚠️ If you only need to cat files, please use https://github.com/campoy/embedmd instead.

Install

Binaries

See Releases

Source

$ go get -v github.com/jpillora/md-tmpl

Usage

$ mk-tmpl

  Usage: md-tmpl [options] [files...]

  Options:
  --preview, -p  Enables preview mode. Displays all commands encountered.
  --write, -w    Write file instead of printing to standard out
  --help, -h

Insert templates in the form:

<!--tmpl,options:command --><!--/tmpl-->

where command is a shell command and options are listed below

Options

• chomp - trims any trailing newline generated by command
• code - wraps the output of command in triple backticks

Examples

Create a foo.md with a template tag

_Updated on <!--tmpl,chomp:date --><!--/tmpl-->_

Then you execute the templates and rewrite foo.md with:

$ md-tmpl -w foo.md

Now, foo.md should be:

_Updated on <!--tmpl,chomp:date -->Sun 31 Mar 2019 00:41:18 AEDT<!--/tmpl-->_

And appear will test display on Github, like:

Updated on Sun 31 Mar 2019 00:41:18 AEDT

More Examples

• Dynamic examples (cat examples/foo)
• Usage text (prog --help)
• Update timestamps (date)

⚠️ Warnings

• Malicious tags. Commands are run by piping strings straight into bash. If you think someone has slipped a rm -rf / in one of your markdown files, you can view all nested commands with the --preview, -p option.
• Currently it has only been tested on Markdown hosted on Github (GFM).
• You cannot use > in your commands as it marks the end of the command by closing the tag, use > instead.
