description
This experimental plugin provides some help with the definition of
functions that should be called when the cursor position changed.

When the cursor position changes, it first checks if a certain condition
is met and then calls functions registered in
[bg]:hookcursormoved_{CONDITION} (an array).

Pre-defined conditions:
    linechange
        The line-number has changed.
    parenthesis
        Cursor is over (), [], or {}.
    syntaxchange
        The syntax group under the cursor has changed (i.e. the cursor
        has moved in/out of a syntax group.
    syntaxleave
        b:hookcursormoved_syntax (ARRAY) should contain the syntax names
        which should run the hook code.
    syntaxleave_oneline
        Same as a above but check also for changes of the line number.

In order to define a new conditions, you have to define a function
"HookCursorMoved_{CONDITION}(mode)", which returns true if the condition
is met.

Functions are best registered using |hookcursormoved#Register()|.
Example: >

    function! WhatsGoingOn(mode) "{{{3
        if mode == 'i'
            DoThis
        elseif mode == 'n'
            DoThat
        endif
    endf

    call hookcursormoved#Register('b', 'syntaxchange', function('WhatsGoingOn'))
