Development Libraries and 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.
- ghci powerful and extensible debugger for GHC.
- 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.
- HLint - Detect common style mistakes and redundant parts of syntax, improving code quality.
- Haskabelle - Convert haskell programs to isabelle theories.
- Catch - Detect common sources of runtime errors (currently difficult to compile)
- Sourcegraph - Haskell visualizer
Also, GHC when using the "-Wall" option provides a great deal of useful feedback.
Libraries for testing Haskell.
- QuickCheck - powerful testing framework where test cases are generated according to specific properties.
- HUnit - unit testing framework similar to JUnit.
- Hspec - a testing framework similar to RSpec with support for QuickCheck and HUnit
- test-framework integrates both Hunit and QuickCheck
- The Haskell Test Framework, HTF integrates both Hunit and QuickCheck.
- 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"
- SmallCheck - Similar to QuickCheck, but tests all values up to a particular depth rather than using a sample of randomly generated values.
- dejafu - overloadable primitives for testable, potentially non-deterministic, concurrency.
Dynamic Analysis Tools
Tools that analyse your program's run-time behavior to provide useful information, such as coverage or benchmarks.
- hat - analyse each evaluation step of your haskell program.
- hpc - check evaluation coverage of a haskell program, useful for determining test coverage.
- criterion - powerful benchmarking framework.
- threadscope - a new feature on the horizon which allows for benchmarking and visualization of multithreaded performance.
- ghc profiling tools - a powerful suite of profiling tools exist within GHC itself
Tools that aid the development process, such as build tools, revision control systems, and similar, while not performing any interaction with the code itself.
