When developing a package, package-install-from-buffer is a very useful
command. It installs the current buffer as an Elpa package, so you can test
installation, byte-compilation, autoloading, and activation, all in one fell
swoop. If your package has multiple files, however, it gets a little more
complicated.
Earlier this month, I asked on Emacs.SE whether there was a simple way to
manually install a multifile package. As discussed in Phils' answer, you need to
create a -pkg.el file, tar the package, and then invoke a command on the tar
file. That's two steps too many for me, so a push to master was in order.
** package-install-from-buffer and package-install-file work on directories.
This follows the same rules as installing from a .tar file, except the
-pkg.el file is optional.
There are no new commands to remember. Just issue package-install-from-buffer
from a dired buffer, or invoke package-install-file and give a directory.
Whichever package is contained in that directory will be read and installed, be
it single or multifile, no taring or -pkg.el file necessary.
