[rmail-mbox-branch]: inital problems

[Alfred M. Szmidt]

If you start rmail without having a file to read (or if you read a
babyl-RMAIL file), you get the following:

No messages to show.  Add something better soon.
rmail-desc-get-keywords: Args out of range: [], 0


Opening an existing mbox file on the other hand produces this:

Processing new messages...
rmail-get-sender: Symbol's function definition is void: mail-strip-quoted-names



I got the rmail mbox branch by going to the lisp/mail directory and
running "cvs up -r rmail-mbox-branch".  And recompiled emacs, and
installed it.


Happy hacking.

Re: [rmail-mbox-branch]: inital problems

[Alfred M. Szmidt]

It would be nice if the new rmail would report an error if it is
trying to open a old mailbox.  Right now it just assumes that it knows
what it is doing, and will barf with a babyl formated mailbox.


As for your patch, it worked.  Will poke around and see what I can
break...  Thanks.

rmail-edit-current-message will result in the following error:

Re: [rmail-mbox-branch]: inital problems

[Richard Stallman]

    Processing new messages...
    rmail-get-sender: Symbol's function definition is void: mail-strip-quoted-names

That function is in mail-utils.  Can you add

  (require 'mail-utils)

to the beginning of rmail-get-sender as a quick fix for this,
so you can test it some more?

Will this do?  I am not all that familiar with the elisp debugging
facilities...

Note that the mailbox doesn't contain any messages as of yet, which
probobly why the error happens. That is, it assumes that there is a
message and tries to edit it.

I don't like it, it does the check far far to late.  It should do it
before switching to any modes.
