1) Pla v1.0 - pxx for making templates
Archive: <https://sympa.inria.fr/sympa/arc/caml-list/2016-06/msg00091.html>
------------------------------------------------------------------------
** Leonardo Laguna Ruiz announced:

Pla is a simple library and ppx syntax extension to create composable templates
based on verbatim strings.

You can find the code and a quick description of it?s features

<https://modlfo.github.io/pla/>

In a nutshell, the ppx transforms quoted strings in the form {pla| ?. |pla} to
templates. Inside templates it?s possible to add markers whose contents is
replaced by other templates, for example:

let name = Pla.string ?pla? ;;
let t = {pla|The library name is <#name#>|pla} ;;

will produce ?The library name is Pla?

When compiled, the markers are type-safe.

Pla does not provide advanced pretty-printing features but it produces fast
functions to create large amounts of text.
