"""Spell checking for the wx.StyledTextControl using pyenchant

This module was insipred by the spell check function from Christopher Thoday's
U{Luke SDK<http://luke-sdk.berlios.de/>}.

Spell checking is provided by the pyenchant library, which is an external
dependency not part of wxPython.  Packages are available for Mac, Unix, and
windows at U{http://pyenchant.sourceforge.net}

Currently provides:
 - spell checking of entire buffer, currently visible page, or selection region
 - user specified indicator number (0 - 2), style, and color
 - language can be changed on the fly
 - update the spelling as you type
 - check the document in either idle time or in a background thread

@author: Rob McMullen
@version: 1.2

        - Rewrote as a standalone class rather than a static mixin
        - Added helper function to use idle processing time to check document
        - Added word checking function for use in instant spell checking
        - First public release

    """Spell checking for use with wx.StyledTextControl.
    This shows spelling errors using the styling indicators (e.g.  the red
    squiggly underline) of the styled text control; I find this much more
    convenient than a dialog-box that makes you click through each mistake.
    The eventual goal of the module is to provide on-the-fly spell checking
    that will display errors as you type, and also will highlight errors
    during idle time or in a background thread.
    Spell checking is provided through the pyenchant module.  Without
    pyenchant, this object won't do anything useful, but it is still safe to
    be used.  It wraps all calls to pyenchant with try/except blocks to catch
    import errors, and any calls to the spell checking functions will return
    To use the spelling check, use one of the methods L{checkAll},
    L{checkCurrentPage}, or L{checkSelection}.  Clear the spelling
    indicators with L{clearAll}.
