Very interesting program, and intelligently made.

I’m looking forward to more about templates.

Nice framework idea. Most tend to be bloated and try to be the end all be all of coding.

Thanks for the great post.

After a week of lurking I finally understand how to use this stuff.

The function “menuRows” turned out to be the most difficult to understand, BTW. :)

After some fiddling with hvac + lighttpd, I came to the conclusion that the lighttpd-packages in Debian testing are *broken*. (Maybe also in Ubuntu). The latest version on 1.4.20 works, however. My config, for the example, is as follows:

server.document-root = “/var/www”
server.modules = ( “mod_fastcgi” )
server.port = 3000

fastcgi.debug = 1
fastcgi.server = ( “/test” =>
(
(
“socket” => “/tmp/test.sock”,
“bin-path” => “/path/to/hvac-board”,
“min-procs” => 1,
“max-procs” => 1,
“check-local” => “disable”
)
)
)

[...] HStringTemplate is a Haskell port of Terence Parr’s StringTemplate engine (originally for Java but also available for C# and Python). StringTemplate is a templating engine along the lines of Apache Velocity but is more restrictive in what processing it permits templates to perform. Specifically, it strictly enforces separation between model and view. It is not possible for a template to cause side-effects elsewhere (no database updates, etc.). StringTemplate can be used for generating any kind of text output, not just XML/HTML. In fact, one of its principal uses is as a code generator for ANTLR. [...]

It looks like this templating system completely lacks computation of any kind (you can’t add two numbers within template, can you?).

I find this somewhat confusing. Do you know of XSLT? It looks pretty much the same (no side-effects, support for recursive template substitution, etc.), except for many-many details (syntax, functions, etc.). :)

Do you think it is better to compute everything outside of templates? And how about treating output as a document (not a raw string)? I suppose it would reduce the number of common syntactical errors, as well as provide some output validation.

In response to George, it took a little time for me to get used to the most elegant way to order function arguments. Take a look at the types in Data.Map, for example, insert is k -> a -> Map k a -> Map k a. This order supports currying of the template, so I can do:

setMyAttributes = setAttribute “key1″ “value1″ . setAttribute “key2″ “value2″

Instead of:

setMyAttributes t = setAttribute (setAttribute “key2″ “value2″ t) “key1″ “value1″
