Being myself an ex-TeXtures user and loking at some of my cooleagues
still using TeXTures,
I share your opinion.
But the situation is really different here:
1- we can see from the Finder what is inside a bundle
2- the bundle can be turned into a normal directory
Newbies will use TeX bundles as is, then with more experience, they
will take a look at the insides,
and for advanced use they will let down the bundle.
Moreover, the frontend can be smart enough to let the user easily
switch between folder and bundle
some checkbox "TeX wrapper is a Mac OS X bundle" versus "TeX wrapper is
a normal directory"

emacs is using TeX comments at the top of any text file to define the
encoding but a limited set of such encodings are used.
AUCTeX is using TeX comments at the end of the TeX file for the master
document and is using an external directory named in general auto/
where it stores private data.
TeXniCenter also uses an external file to store meta data, I don't know
if TXC is encoding aware...
IMO, the only thing that really needs to live in the file itself is the
If the master document info is pertinent, it means that you have at
least 2 documents gathered in one folder because... then there is no
problem in having one more external location where you store data.
I explained in one of my previous mails how the master document
information can be in only one location, but not in any input file.
Moreover, the input files are not only text documents and may not be
Suppose you are working on a TeX document including PDF images, you can
open one of the pdf images using your integrate frontend.
The frontend will be smart enough to guess that this image is in fact
part of a more general project and if you finally decide to edit your
project everything will already be available in the frontend. How the
frontend will be able to guess that this image file belongs to a
project? Nothing will be available from the pdf contents, in fact the
frontend will be able to find an external file where meta information
IMO, the encoding information is the only one that should be available
from the TeX file itself.
It seems that this information is available as a universal standard
only for UTF16 text files.
Wait for final TeXShop to have the exact syntax to declare the
encoding, something like
%!TeX encoding = blah
except that the whole syntax must be carefully described.
This is the only thing that might eventually survive the TeX project
design because it is not too much intrusive
and will not pollute the source more than necessary, whatever editor
you are using (alpha, bbedit, vi, emacs...).
Moreover, there is an implementation trick for smart editors that hides
this information from the user.
I understand the meta data problem as: Will I have to drag two files
instead of on?
The answer could be: no longer drag individual files, just drag single
The problem is now that most xfer tools only accept flat files and do
not like directories at all.
I have not yet the answer to that, only some ideas like a contextual
menu item in the finder that lets you "flaten" a TeX wrapper directory.
