[Haskell-cafe] ANNOUNCE: doctest-0.3.0

[Simon Hengel]

I just uploaded a new version of doctest[1] to Hackage.


WHAT IS doctest?
================

doctest is a port of Python's doctest[2] to Haskell.  It can be used to
verify, that examples in Haddock comments[3] do still work.  This also
provides you with a simple mechanism to write unit test, without the
burden of maintaining a dedicated test suite.

A basic example of usage is at [4].


WHAT'S NEW IN THIS VERSION?
===========================

It is now possible to intersperse comments between a longer, continuing
example.  All examples within the same comment now share a namespace.
The following now works :

    -- | Calculate Fibonacci number of given 'Num'.
    --
    -- First let's set `n` to ten:
    --
    -- >>> let n = 10
    --
    -- And now calculate the 10th Fibonacci number:
    --
    -- >>> fib n
    -- 55
    fib :: Integer -> Integer
    fib 0 = 0
    fib 1 = 1
    fib n = fib (n - 1) + fib (n - 2)

Thanks to Sakari Jokinen for this contribution!

In addition I changed the name from DocTest to doctest.  I think using
all lower-case package names is a good thing.  And as we will use
doctest as a library in the near future, this was the last chance for
this change.

Cheers,
Simon
