Re: [Alphacocoa-devel] Alpha files

[Joachim K. <ko...@ma...>]

Dear Bernard,

I am really happy with the new Alpha (9.1.3).
Thanks so much for all your work.

I have a question:

I would like to be able save a file in Alpha (without
file extension), and then have Alpha open it when
I double-click it in the Finder.

I have tried the following: in the 'I' popup, select
'Record Window State' and 'Set Alpha as creator'.
The first problem is that any subsequent 'Save' action
will erase this second choice -- at least that's how
it looks in the popup menu.

In any case, it does not help: when I double-click the
file in the Finder, TextEdit opens instead of Alpha :-(

I would also like to ask if there is any way to set a
preference flag in Alpha to force 'Record Window State'
and 'Set Alpha as creator' automatically always?

In the old days, this stuff would be in the resource
fork. Nowadays I assume it should be in xattributes...?
Here is what I see

% xattr myfile
com.apple.FinderInfo
com.apple.TextEncoding
com.apple.lastuseddate#PS
com.apple.metadata:_kMDItemUserTags
com.dropbox.attrs
net.sf.alpha.break
net.sf.alpha.enc
net.sf.alpha.font
net.sf.alpha.geo
net.sf.alpha.sel
net.sf.alpha.tab
net.sf.alpha.wrap
% xattr -p com.apple.FinderInfo myfile
54 45 58 54 41 4C 46 41 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
xattr -p com.apple.metadata:_kMDItemUserTags myfile
62 70 6C 69 73 74 30 30 A0 08 00 00 00 00 00 00
01 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 09

I don't know what all hex stuff means, or
if it is related to the issue at all.

(I am well aware that all this might really be an
OSX problem (I am reporting from 10.15), not an
Alpha problem, but if you have an idea of how to
solve it nevertheless, I would be very grateful.)

Thanks a lot in advance.

Cheers,
Joachim.
