Here comes a report of a first little testdrive.

It compiled fine, but i forgot about that gnome-autogen,
so i had to find an old autogen.sh, then it went on.
Where on earth do i find that "gnome-common"?

First i did not get it, advrename looked just like
before... Well of course, that $T(....) is supposed
to be written in the "replace with" box i thought.
So i tried:

Replace this: .jpg

With this: $T(Exif.DateTime).jpg

Hard crash when i hit enter, GCMD just died on me.
I suppose it is not ment to be written like that,
but it is not good that it crashes if the user makes
an error like this.

Hehe.. Is it obvious that i never use the advrename
in advanced ways?

Then i tried a new replace:

Replace this: _

With this: _$T(Exif.DateTime)_

Well, i got a file named: img_$T(Exif.DateTime)_2670.jpg

:-) ...

I am obviously missing something here, but what..

I think this advrename is in need of a help file..
Now i did some RTFM in the usual places.. found the
advrename textfile in the source. That helped.

Tried following "Template" (would "Rule" be a
better name?):

$N(0,3)_$T(Exif.DateTime)_$N(4)

Hey.. :-)
It works!

Added also a Replace-with rule to replace spaces and colons
in the time stamp, this on two files containing Exif info.

Works fine.

Now what happens if i add a jpeg without Exif to those
two? Found a bug! The above "Template" then wanted to
rename the Exif-less file "malmlok.jpg" to "mal__lok.jpg",
i do not think it should do that.

Now lets try Exif keywords on a file that exif reports
as this:

/home/magnus/test/malmlok.jpg:

 2:120    Caption/Abstract     String      35  Malmlok på bangården i 
Vitåfors.

I bet it will write all keywords, or only the first as
filename... Yep. It used only the first one, this is
not good. My suggestion is to use the last two digits
in the numerical codes as option (without option = take the
first like today), like: $T(IPTC.Keywords.03).


BTW.
Have i reported that the internal viewer IPTC does not
handle swedish? Some months ago i had a little discussion
with the author of libiptcdata, David Moore" about iso/utf-8,
and he said:

"iptc _always_ uses UTF-8 internally, regardless of what your term is
using.  It converts the input from your term's charset to UTF-8, and
then converts the output from UTF-8 to your term's charset.  So it
should work in both places unless something is misconfigured."

So, the data inside my jpeg should be in UTF-8, why does
not GCMD handle it? I mean, most other Gnome-things handle
both iso and utf just fine.
