Bookmarks in non-file buffers?

Bookmarks in non-file buffers?

[Dmitri Minaev]

Is there a way to save the current position (by placing a bookmark or
in any other way) in a buffer that is not associated with a file?
Namely, I'm interested in w3m buffers, pdftotext output and text files
extracted from zip archives in zip-archive mode. Of course, besides
the text position (line number) such bookmarks should contain the
information on how the text was produced.

http://www.emacswiki.org/cgi-bin/wiki/Icicles_-_Multiple_Regions should help,
but no info is saved about "how the text was produced".

You could check session.el ...

From http://emacs-session.sourceforge.net/details.html :
"The buffer must visit a readable file." I'm afraid, this is not what I need.

Actually, what I want is to use Emacs as an ebook reader. Most of my
books are in  (or, at least, can be converted into) html and pdf. A
necessary feature of any book-reading program is to save the last
location in the current file. I tried w3m-session-save for html files,
but it only saves the current url, not the point in the buffer.

As for the Icicles recommended by Drew, I had an impression from the
manual that the multiple regions don't keep the mode used to open the
file.

If you use CVS Emacs, see bookmark-make-record-function.

I do, but it's been two months since I updated Emacs. Looks like this
variable is what I need. Thank you!

Then maybe the doc needs clarifying - if so, please let me know the particulars.


This feature is about saved regions (which you name/tag) - any number, from any
buffers. If you revisit the buffers later, you can revisit the regions.

Presumably, when you revisit such a buffer you revisit it in the proper mode -
that is independent of this feature; it imposes no mode.

Also, keep in mind that if the buffer content changes, then the saved regions
might be displaced, but that should not be the case for html and pdf files,
unless you modify them. This caveat is why I did not simply recommend this
feature to you - I said that it might help you. From your description so far, I
still think it might help.
