[[Category:Tools]]

This page contains a list of useful tools and libraries used frequently in Haskell development, for things such as debugging, benchmarking, static analysis and testing.

== Debuggers ==

* [http://www.haskell.org/haskellwiki/GHC/GHCi ghci] powerful and extensible debugger for GHC.
* [http://www.haskell.org/hugs/ hugs] a haskell interpreter that includes debugging facilities.

== Static Analysis Tools ==

Tools that perform some form of analysis on your code and provide useful feedback.

* [http://community.haskell.org/~ndm/hlint/ HLint] - Detect common style mistakes and redundant parts of syntax, improving code quality.
* [http://web.archive.org/web/20170822153049/https://www.cl.cam.ac.uk/research/hvg/Isabelle/haskabelle.html Haskabelle] - Convert haskell programs to isabelle theories.
* [http://web.archive.org/web/20180918160517/community.haskell.org/~ndm/catch/ Catch] - Detect common sources of runtime errors (currently difficult to compile)
* [http://hackage.haskell.org/package/SourceGraph-0.5.5.0 Sourcegraph] - Haskell visualizer
Also, GHC when using the "-Wall" option provides a great deal of useful feedback.

== Testing Frameworks ==

Libraries for testing Haskell.

* [http://www.cs.chalmers.se/~rjmh/QuickCheck/ QuickCheck] - powerful testing framework where test cases are generated according to specific properties.
* [http://hackage.haskell.org/package/HUnit-1.2.2.1 HUnit] - unit testing framework similar to JUnit.
* [https://hackage.haskell.org/package/microspec microspec] - a tiny QuickCheck test library with minimal dependencies
* [http://hspec.github.io/ Hspec] - a testing framework similar to RSpec with support for QuickCheck and HUnit
* [http://batterseapower.github.com/test-framework/ test-framework] integrates both Hunit and QuickCheck
* [http://hackage.haskell.org/package/HTF The Haskell Test Framework, HTF] integrates both Hunit and QuickCheck.
* [http://documentup.com/feuerbach/tasty Tasty] - from the website: "lets you combine your unit tests, golden tests, QuickCheck/SmallCheck properties, and any other types of tests into a single test suite"
* [https://github.com/feuerbach/smallcheck SmallCheck] - Similar to QuickCheck, but tests all values up to a particular depth rather than using a sample of randomly generated values.
* [https://hackage.haskell.org/package/dejafu dejafu] - overloadable primitives for testable, potentially non-deterministic, concurrency. See also the [https://mail.haskell.org/pipermail/haskell-cafe/2015-August/121023.html announcement].

== Dynamic Analysis Tools ==

Tools that analyse your program's run-time behavior to provide useful information, such as coverage or benchmarks.

* [http://web.archive.org/web/20111002214249/http://community.haskell.org/~ndm/hat/ hat] - analyse each evaluation step of your haskell program.
* [http://web.archive.org/web/20090705020757/projects.unsafeperformio.com/hpc/ hpc] - check evaluation coverage of a haskell program, useful for determining test coverage.
* [http://hackage.haskell.org/package/criterion criterion] - powerful benchmarking framework.
* [http://code.haskell.org/ThreadScope/ threadscope] - a new feature on the horizon which allows for benchmarking and visualization of multithreaded performance.
* [http://www.haskell.org/ghc/docs/latest/html/users_guide/profiling.html ghc profiling tools] - a powerful suite of profiling tools exist within GHC itself

== Ancillary Tools ==

Tools that aid the development process, such as build tools, revision control systems, and similar, while not performing any interaction with the code itself.

* [http://darcs.net/ darcs] revision control system 
* [http://www.haskell.org/haddock/ haddock] documentation system
* [http://www.haskell.org/cabal/ cabal] build system
* [http://web.archive.org/web/20130915123541/community.haskell.org/~ndm/hoogle/ hoogle] type-aware API search engine
* [http://hackage.haskell.org/package/lentil lentil] frugal issue tracker
