Install the gem and add to the application's Gemfile by executing:

$ bundle add pandoc_binary

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install pandoc_binary

After installation, we can use pandoc command:

$ pandoc --from=gfm --to=html5 a.md > /tmp/a.html

And we can use PandocBinary.executable_path to get pandoc command path:

require "pandoc_binary"

p(PandocBinary.executable_path)
#=> #<Pathname:/home/yuya/.anyenv/envs/rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/pandoc_binary-2.10/libexec/pandoc-linux-amd64>
