Simple string interpolation using OCaml's ppx extension points API.

• How to use

Write [%str "some string"] anywhere a string expression is expected. Use $(name) to insert the value of variable "name" whose types needs to be string. Use $$ to insert an actual dollar character.

#+begin_src tuareg let name = "mario" in print_string [%str "It's a meee, $(name)\n"] #+end_src

See directory src_test for examples on what to do and not to do.

• How to build

• install OCaml 4.02 (or newer)

  • support arbitrary OCaml expressions inside $(...). Needs to run the OCaml lexer on the string, skip over balanced parenthesis and pass this to OCaml Parse.expression.
