[xemacs-hg @ 2003-04-14 03:40:26 by youngs] 2003-04-14 Steve Youngs <youngs@xemacs.org> * package-admin.el (package-admin-find-top-directory): Use 'directory-sep-char'. (package-admin-get-install-dir): Ditto. This is so PUI won't break on platforms that don't use '/' as the directory separator. * package-get.el (package-get-pgp-available-p): New. (package-get-require-signed-base-updates): Use it. (package-get-update-base-from-buffer): Move the code that finds the gpg stuff into `package-get-pgp-available-p'. Now if you have Mailcrypt and a PGP binary installed and set up on your system, PUI will automatically default to doing PGP verification, otherwise it'll default to off. (package-get-require-base): Use the DATUM arg to `error'. (package-get-locate-index-file): Ditto. (package-get-update-base): Ditto. (package-get-update-base-entries): Ditto. (package-get-all): Ditto. (package-get-dependencies): Ditto. (package-get-info): Ditto. (package-get): Ditto. * package-info.el (batch-update-package-info): Use the DATUM arg to `error'. * package-net.el (package-net-batch-generate-bin-ini): Use the DATUM arg to `error'. * package-ui.el (pui-toggle-package-key): Use the DATUM arg to `error'. (pui-toggle-package-delete-key): Ditto. (pui-install-selected-packages): Ditto. (pui-add-required-packages): Ditto. (pui-display-info): Ditto. (list-packages-mode): Ditto. * packages.el (package-require): Use the DATUM arg to `error'.
