This repository contains the implementation of the Curry preprocessor
currypp which supports some extensions for Curry programs, like
printf), HTML and XML code,
Details about the usage can be found in the manual. Here is a short summary of the usage of integrated code.
If the pre-processor is installed as the binary
currypp, Curry source files containing integrated code can be translated by running
currypp as follows:
currypp <org-filename> <input-file> <output-file> foreigncode [-o]
The parameters are:
-ois given, a copy of the translated code is stored in the file
The basic syntax of integrated code in Curry program looks like
langtag is a tag indicating the kind of integrated language, and
expression is an expression of this language.
If `` or '' are used in the expression itself, the enclosing accents need to be of higher number than the inner graves, i.e., the following integrated code expression is also allowed:
The number of opening and closing accents must always be identical.
Currently, the following
langtag values are supported:
printf Syntax printf - same as above (but with an implicit
putStr call) regex - Polymorphic regex expressions html - Standard HTML xml - Standard XML sql - SQL syntax
See the examples and source file comments for further details.
