HLint gives suggestions on how to improve your source code.
Hoogle is a Haskell API search engine, which allows you to search many
standard Haskell libraries by either function name, or by approximate type
signature.
An evolution of 'reshape2'. It's designed specifically for data
tidying (not general reshaping or aggregating) and works well with
'dplyr' data pipelines.
Simple time library focusing on simple but powerful and performant API
The backbone of the library are the Timeable and Time type classes.
Each Timeable instances can be converted to type that has a Time
instances, and thus are different representations of current time.
Hsb2hs is a preprocessor that allows you to include the contents of
files as string literals in your Haskell programs and libraries. It is
an alternative to file-embed for those who do not want to rely on
Template Haskell.
hslogger is a logging framework for Haskell, roughly similar to Python's
logging module.
hslogger lets each log message have a priority and source be associated
with it. The programmer can then define global handlers that route or
filter messages based on the priority and source. hslogger also has a
syslog handler built in.
The Scripting.Lua module is a wrapper of Lua language interpreter. This
package contains full Lua interpreter version 5.1.5.
This package exposes internal types and functions that can be used to
extend Hspec's functionality.
Automatically discover and run Hspec tests.
Catchy combinators for HUnit.
