HtmlMacros 2.3

A generic framework for writing static macros in Java to generate elaborate boilerplate in HTML text files on the desktop without requiring any server side coding. It could also be used to expand macros in any text files.
The basic idea is this. You embed magic comments in your HTML that look like something like this (with angle brackets shown here as [].
[!-- macro Measure 20 cm --]
Then you run htmlmacros.exe and it expands those comments to
boilerplate that looks like this:
[!-- macro JDisplay Measure 20 cm --]
[!-- generated --]
[span class="metric"]20 cm[/span]
[span class="imperial"](7.87 in)[/span]
[!-- /generated by Measure --]
and renders colourised for your viewers like this:
20 cm (7.87 in)
