| − | ==What is DocTest== |
||
| − | DocTest is a small program, that checks |
||
| − | [http://www.haskell.org/haddock/doc/html/ch03s08.html#id566093 examples in Haddock comments]. It is modeled after |
||
| − | [http://docs.python.org/library/doctest.html doctest for Python]. |
||
| + | [[Category:Pages to be removed]] |
||
| − | ==Installation== |
||
| − | DocTest is available from |
||
| − | [http://hackage.haskell.org/cgi-bin/hackage-scripts/package/DocTest Hackage]. |
||
| − | Install it, by typing: |
||
| − | <pre> |
||
| − | $ cabal install doctest |
||
| − | </pre> |
||
| − | |||
| − | ==Usage== |
||
| − | Below is a small Haskell module. The module contains a Haddock comment with some examples of interaction. The examples demonstrate how the module is supposed to be used. |
||
| − | |||
| − | <haskell> |
||
| − | module Fib where |
||
| − | |||
| − | -- | Compute Fibonacci numbers |
||
| − | -- |
||
| − | -- Examples: |
||
| − | -- |
||
| − | -- >>> fib 10 |
||
| − | -- 55 |
||
| − | -- |
||
| − | -- >>> fib 5 |
||
| − | -- 5 |
||
| − | fib :: Int -> Int |
||
| − | fib 0 = 0 |
||
| − | fib 1 = 1 |
||
| − | fib n = fib (n - 1) + fib (n - 2) |
||
| − | </haskell> |
||
| − | |||
| − | (A line starting with <hask>>>></hask> denotes an ''expression''. |
||
| − | All comment lines following an expression denote the |
||
| − | ''result'' of that expression. Result is defined by what an [http://en.wikipedia.org/wiki/Read-eval-print_loop REPL] |
||
| − | (e.g. ghci) prints to <hask>stdout</hask> and <hask>stderr</hask> when |
||
| − | evaluating that expression.) |
||
| − | |||
| − | With DocTest you may check whether the implementation satisfies the given examples, by typing: |
||
| − | |||
| − | <pre> |
||
| − | $ doctest Fib.hs |
||
| − | </pre> |
||
| − | |||
| − | You may produce Haddock documentation for that module with: |
||
| − | |||
| − | <pre> |
||
| − | $ haddock -h Fib.hs -o doc/ |
||
| − | </pre> |
||
| − | |||
| − | ==Hacking== |
||
| − | DocTest is still experimental. |
||
| − | You can find a reference to the public source repository at |
||
| − | [http://hackage.haskell.org/cgi-bin/hackage-scripts/package/DocTest Hackage]. |
||
| − | |||
| − | Patches are gladly welcome! |
