The new syntax supports the same operations as the old syntax, but is
clearer to understand and more extensible in the future. The old syntax
is still supported for now.
In most cases the file order is not important and the unsorted output
hurts readability. The performance impact of sorting is relatively
small and barely noticeable even with large resource files.
Previously all non-ASCII characters were hex-escaped on output.
However, many resource files use MacRoman characters in resource names
and sometimes in resource types, so it makes sense to use MacRoman in
the interest of readability.
Previously, when some aspect of a resource's metadata was not present
(e. g. a resource with no name), the description would
explicitly point this out (and e. g. say "unnamed"). Now missing parts
of the metadata are simply omitted from the description, resulting in
cleaner output in many cases.
The resource description formats used by the listings and dumps have
also been unified. Previously the descriptions were structured slightly
differently in each case; this is now no longer the case.
The broken non-seeking read implementation of ResourceFile is removed,
and non-seekable streams are now handled by reading the entire stream
data first and wrapping it in a BytesIO to make it seekable.
The manual selection of seeking/non-seeking reading has been removed as
well, since it is no longer needed and was already nearly useless.
Unfortunately, reStructuredText requires nested lists to be exactly
visually aligned. There is no single indent size that works for all
lists - for example bullet point lists require two spaces, but numbered
lists require three spaces (or more, depending on how high the numbers
go). This makes reStructuredText incompatible with tab indents.
Added the attributes "Resources Locked" and "Printer Driver MultiFinder
Compatible" from ResEdit, as well as more dummy constants (512-16384)
for attributes with no known meaning.
