Not quite correct. jka-compr relies on the extension, but crypt++ does not. It peeks inside the file and uses a magic number technique. I've used crypt++ to automagically decode many gzip'd files w/o the `.gz' filename extension. -- -mb- ^ permalink raw reply [flat|nested] 4+ messages in thread

Hmm I think I switched from crypt++ to jka-compr when crypt++ didn't work too goo good together with rmail (yep it was those old days), I think it was that crypt++ couldn't handle appending to files. Is it something to be worried about in gnus? Åndy -- Hi I am an alien .sig, and at the moment I am having sex to your mind, by looking at your smile I can see that you like it.

That was the last time I looked at it, and jumped to the initial version of jka-compr. AE> I think it was that crypt++ couldn't handle appending to files. That was at least as much the fault of the Unix compress as crypt+. The Unix compress format is not a streaming format, so you cannot append to an existing, compressed file. You could get around that limitation by visiting the file before appending. Emacs will append to the file buffer instead of the disk image, and you can write out the modified buffer afterwards. This is how I did it back when I used Rmail. As for Gnus, support for compressed files is still problematic at best, and practically nonexistant when it comes to file extensions on numeric file names (nnm[lh] folders, for instance). -----BEGIN PGP SIGNATURE----- Version: 2.6.3 Charset: noconv iQCVAwUBMfYmeJ6VRH7BJMxHAQEvIAQAlA1HF/bPAmm3cCQITO/i9R8zJww30QpH Rwc6DSR4gfKlzCSOOck0790mrzyr2CP9dICTEILNTWKQhjgNRdckA9gKRNO5Fk7g fC8E1A1CGldUbGUl+ObbDaH2Hl46NJ32PFI0tcC3J36c22pdvOG0GdiNLqWcM56E OckWtC8R8qw= =0oC1 -----END PGP SIGNATURE----- -- Richard Pieri/Information Services \ Curiosity never killed anything, except <ratinox@unilab.dfci.harvard.edu> \ maybe a few hours. -A cat's guide to life http://www.dfci.harvard.edu/ \ ^ permalink raw reply [flat|nested] 4+ messages in thread
