==========
API design
==========

The API is designed to be **easy to use** and consistent. Ease of use is
measured by the number of calls to achieve a concrete high level action.


Naming scheme
=============

The library uses a simple naming scheme that makes use of common abbreviations
to keep the names short but meaningful. Since version 0.8.2 many symbols have
been renamed to fit this scheme. The ultimate goal is that the programmer can
*guess* a name.

-------------------     ------------   --------------------------------------
initialize              initT          ``init`` is used to create a
                                       value type ``T``
new                     newP           ``new`` is used to create a 
                                       reference type ``P``
find                    find           should return the position where
                                       something was found; for a bool result
                                       use ``contains``
contains                contains       often short for ``find() >= 0``
append                  add            use ``add`` instead of ``append``
compare                 cmp            should return an int with the
                                       ``< 0`` ``== 0`` or ``> 0`` semantics;
                                       for a bool result use ``sameXYZ``
put                     put, ``[]=``   consider overloading ``[]=`` for put
get                     get, ``[]``    consider overloading ``[]`` for get;
                                       consider to not use ``get`` as a
                                       prefix: ``len`` instead of ``getLen``
length                  len            also used for *number of elements*
size                    size, len      size should refer to a byte size
capacity                cap
memory                  mem            implies a low-level operation
items                   items          default iterator over a collection
pairs                   pairs          iterator over (key, value) pairs
delete                  delete, del    del is supposed to be faster than
                                       delete, because it does not keep
                                       the order; delete keeps the order
remove                  delete, del    inconsistent right now

directory               dir
path                    path           path is the string "/usr/bin" (for
                                       example), dir is the content of
                                       "/usr/bin"; inconsistent right now
