The Spicey Web Application Framework

To generate an application, follow the steps below.

1. Create a Curry program containing a constant of type Database.ERD.ERD (the module Database.ERD is part of the package cdbi) which describes your entity-relationship model (see the file "examples/BlogERD.curry" as an example).

2. Execute spiceup and supply the name of the Curry ERD program, e.g.,

   spiceup .../BlogERD.curry

This generates the complete source code of the initial application as a Curry package (see the generated file README.txt for some explanations).

You can also provide a file name for the SQLite3 database in which all data is stored, e.g.,

   spiceup --db BlogData.db .../BlogERD.curry

If the parameter "--db ..." is not provided, then the name of database file is ".db" where is the name of the specified ER model. Since this file name will be used in the generated cgi programs, a relative file name will be relative to the place where the cgi programs are stored. In order to avoid confusion due to relative file names, it might be better to specify an absolute path name for the database file. This path could also be set in the definition of the constant sqliteDBFile in the generated Curry program Model/<ERD>.curry.

3. Change into the generated directory containing all sources as a Curry package, e.g., by cd Blog.

4. Define in the Makefile the variable WEBSERVERDIR (and possibly other variables, like SYSTEM or CURRYOPTIONS).

5. Install all required packages by make install.

6. Compile the generated programs by make compile.

7. Execute make deploy to deploy the web application.

8. After the successful compilation, the application is executable in a web browser by loading <URL of web dir>/spicey.cgi.

Note that the database is generated with the cdbi package. Hence, one can also use embedded SQL statements when further developing the Curry code. The syntax and use of such embedded SQL statements is described in the Curry preprocessor.
