Rendering link Templates.

[lloydtabb]

Often in an HTML table you want to link to some external resource. This simple mechanism allows create linkage in the result table with simple text substitution.

run: flights -> {

  // by default appends to the end of the template

  # link.url_template="http://faa.gov/lookup?code="
  group_by: origin_code

  // can also do substitution. $$ is replaced.
  // link.url_template="" and link{url_template=""} are equivalent

  # link{url_template="http://faa.gov/carriers/$$/full_detail"}
  group_by: carrier
}
