ann: rp - a package manager for ringojs
Robert Gaggl
i'd like to announce a project i've been working on for the last
weeks: "rp", a package manager for ringojs (https://github.com/grob/
rp/).
rp is a commandline app which in it's present state allows to publish,
search for, install, activate and list ringojs packages. the registry
that rp works with (also a ringojs app) is running at http://rpr.nomatic.org/.
you can find the source of it at https://github.com/grob/rpr/.
rp is capable to resolve package dependencies and installs packages in
a directory "packages.available" within a ringojs installation - which
is not on ringojs' module search path and thus allows installing
different versions of the same package. package activation is done by
rp using symlinks in packages directory pointing to installed packages
(which is why activation isn't yet supported on windows).
publishing a package in the registry is easy, too: create an account
in the registry, change into the package directory and type "rp
publish". note that currently the initial publisher of a package
becomes its "owner" in rpr - publishing new versions of a package is
limited to this account (until now rpr doesn't have a way to transfer
packages from one account to another).
see the readme on how to install rp. apologies to those running
ringojs on windows, currently you'll need to manually unzip rp into
packages directory if you want to try it out (there's definetly room
for improvement reg. rp on windows).
both rp and rpr are in a very early state, and are by no means
finished in any aspect. however, i hope it is already useful. please
give it a try, i'll be glad to hear your opinions and ideas for
improvement.

I see that packages I already have in my ringojs/packasges directory
are listed as installed by rp. How does it treat those packages? What
happens if I uninstall them?
A minor note: on Linux where the HotSpot server vm is used by default
adding "-J-client" to the java command line in bin/rp helps reduce
startup time by almost half.

or a symlink that doesn't point to packages.available - in other
words, it should not touch anything it didn't install. you'll get an
error message instead. reg. listing: "rp list" shows the active
packages, "rp list -i" the installed ones (those in
packages.available). i wanted "rp list" to show all packages that are
available to ringojs, but maybe that's too confusing.

both 64bit), and -client didn't have any effect. using "-J-d32 -J-
client" did reduce startup time dramatically on os x, but this threw
an error on my linux boxes (probably because i had the 64bit jdk
installed), that's why i hesitated to add that to the rp script.

Good to know! Current behaviour seems reasonable to me.

Did -J-client alone not help on OS X? I think that one should be
available on all Oracle and OpenJDK versions (of course there's other
VMs as well..)

found that at http://blog.headius.com/2010/03/jruby-startup-time-tips.html).
but i'll check again - if it does help i'll put it into the rp script.

dependencies on specific versions of ringojs? It probably should!

created an issue for that: https://github.com/grob/rp/issues/1
