Seacat is a little web framework written in Haskell, which evolved rather naturally from me writing Λδ (detailed below). I think the naturality of producing a little framework, rather than developing in an ad hoc manner, is a testament to why Haskell is good for web development: you actually sit and think about what you're doing.
If you have a recent version of cabal, you can use sandboxes to manage the dependencies.
cabal sandbox init
cabal install --only-dependencies
If not, you'll just have to install the dependencies with all your other packages.
cabal install --only-dependencies
Once you have the dependencies, you can build it the normal way,
cabal configure
cabal build
You can install to the sandbox (good for playing with Λδ), or with the rest of your packages. If you made a sandbox, cabal will install there automatically.
cabal install
There are a couple of different commands for doing different things, in general Seacat execution takes the form,
<seacatbin> <command> [/path/to/configfile]
If the configuration file is omitted, the defaults are used. The commands are as follows,
- migrate: Perform a database migration (includes creating a database).
- populate: Populate the database with sample data.
- runserver: Run the Seacat server.
- clean: Clean out expired ban/limit records (also done every
runserver).
Note: Seacat itself uses a database for IP banning and rate limiting, so if you use those features you need to run a migrate, even if you don't use a database in your application.

Sources have Haddock comments, and you can produce pretty HTML documentation from this,
cabal haddock
Λδ (or Lambdadelta) is an imageboard program written in Haskell. Most imageboards are written in PHP or Perl, but I like applying Haskell to things most people would consider me crazy for, hence this.
This is still heavily a WIP, as most of what I've done so far has been building a microframework from the ground up, rather than actually writing the imageboard bit.
If you used a sandbox for Seacat you can use the same one for Λδ by
just copying the cabal.sandbox.config file.
cabal install --only-dependencies
cabal configure
cabal build
As above, but the name of the executable is lambdadelta,
lambdadelta <command> [/path/to/configfile]
There are some directories that Λδ expects to exist, relative to
file_root in the configuration,
- /board/, home for all board-specific things
- /board/src/, images uploaded to a board
- /board/thumb/, thumbnails of images uploaded to a board
- /banners/, banners to display
- /style.css, stylesheet
