18d192ba70 Use ‘Scientific’ as target type for floats
Close #95.

Here we introduce ‘scientific’ parser that can parse arbitrary big
numbers without error or memory overflow. ‘float’ still returns
‘Double’, but it's defined in terms of ‘scientific’ now. Since
‘Scientific’ type can reliably represent integer values as well as
floating point values, ‘number’ now returns ‘Scientific’ instead of
‘Either Integer Double’ (‘Integer’ or ‘Double’ can be extracted from
‘Scientific’ value anyway). This in turn makes ‘signed’ parser more
natural and general, because we do not need ad-hoc ‘Signed’ type class
anymore.

611f2a4e7e Minor improvements for new combinators
In particular, if input has no newline at the end, we need to treat it
specially, because otherwise we will get confusing “incorrect
indentation” message.

f7f3b02e45 uppercase disclaimer in license
Otherwise it may look like “fine print” for some. Crazy…

c7ed5fe909 after some consulting, it should be “FreeBSD”
What Parsec used is called “FreeBSD” or “BSD 2 clause”. Addition of the
third clause may require contacting all the authors. To hell with it,
let it be “FreeBSD” (which is anyway better than “BSD-like”), I'm a
hacker, not a lawyer (tm).

503a1db4be clarify used license and add missing clause
This commit clarifies license of the software replacing “BSD3” with more
conventional “BSD 3 clause”.

Another change is addition of the third clause originally missing in
license of Parsec (which is licensed under BSD 2 clause license). The
addition of the third clause in form:

* Neither the names of the copyright holders nor the names of
  contributors may be used to endorse or promote products derived from
  this software without specific prior written permission.

does not violate original BSD 2 clause license effectively making it BSD
3 clause license (which I find preferable).

aad1702589 use ‘if’ instead of ‘bool’
This should make maintenance a bit easier. After all ‘if’ looks even
better than ‘bool’ in many cases.

d97398a016 Add compatibility to base-4.7.0.x
This patch introduces compatibility to base-4.7.0.x. It was tested
on Win 8.1 x86_64, using GHC 7.8.4. It mainly consists of a bunch
of #if !MIN_VERSION(4,8,0) ... #endif additions and a lower bound
on base in the cabal file as well as a general introduction of the
CPP extension via default-extensions.

It also removes a potential error source in tests/Util.hs, since
the backslash in /=\ can lead to strange quirks on certain systems
(backslash and newline only separated by whitespace).

Other, squashed commits:

- Remove 'recent version of base' from Readme

- Change necessary version of GHC

d0409a897e implemented flexible tab width
Closes #38.

Now tab width can be manipulated with via the following functions:

* ‘getTabWidth’
* ‘setTabWidth’

Other auxiliary changes were performed, such as updating of
‘updatePosChar’.

This also corrects a bit obsolete descriptions of some functions.

38abf590db make ‘string'’ return actually parsed input
Closes #36.

We should try to preserve original information where possible. User then
can convert case of parsed string if necessary. Previous implementation
discarded actually parsed string and returned argument of the
function — this can be considered as data loss of a sort.

dcc53ad0b7 improved error messages for labelled ‘many’
Closes #35.

Since ‘many’ (and thus ‘some’) are the only combinator that can succeed
consuming input and produce hints at the same time we can conclude that
‘cok'’ continuation in ‘pLabel’ combinator is only called when ‘many’ is
labelled. By correcting label in this case prepending the phrase “rest
of ” to actual label we can greatly improve result error message.
