EWS is a web server construction kit, designed for embedded applications using the GNAT Ada compiler.
The project is hosted on Github.
EWS requires GNAT (GNAT GPL 2012 or later, FSF GCC 4.8.0 or later) and XML/Ada. GNAT GPL 2013 (and, hopefully, later) includes XML/Ada; earlier versions supply XML/Ada as source which has to be built and installed.
In the top-level directory, make will build the library, and make demo will create a server doc/ews_demo, which when executed will listen on port 8080 and respond with the web in the doc/ directory.
The package can be installed with the compiler by make install (more likely, sudo make install). You can install in an alternative place by setting prefix, for example
$ make install prefix=~/local/ews
The facilities available in EWS, and the code for the demonstration, are described in doc/ews.pdf, which is derived from doc/ews.w. As well as being the document source, ews.w also acts as the source code using the Literate Programming facilities of nuweb.py.
