This package 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 how to use integrated code in Curry programs.
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:
The name of the original Curry source file.
The name of the file containing the input to be translated.
The name of the output file where the translated code should be stored.
If the optional parameter
-o is given, a copy of the translated code is stored in the file
To preprocess SQL statements, you might add the option
to use a non-standard info file for the database model
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 enclosing accents are used in the expression itself, the actual enclosing accents need to be of a 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 - same as above (but with an implicit
regex - Polymorphic regex expressions
html - Standard HTML
xml - Standard XML
sql - SQL syntax
