Oh man, so many things updated recently, but this news feed is so not one of them. OK, where to begin. OK...
Cat's Eye Technologies really isn't in the business of making tools. (Implementations of programming languages excepted — they're incidental, they're in service of the languages themselves.)
But we've implemented so many programming languages that, without some kind of tooling, the situation would become unwieldy. So, for example, we designed Falderal and build py-falderal so that all these programming languages could have their example programs presented nicely and tested in an automated way.
But there have been other, more fundamental problems to solve. How do you get all of these implementations onto a machine in the first place, for instance? If the distribution is self-contained, that's not a huge problem — download it and maybe build it and run it. But if it's not self-contained, if it has dependencies (and ultimately they all do, because each implementation is written in something,) then it becomes a package management problem.
And I detest package managers. I don't like their fragile package databases that get corrupted if you look at them wrong. I don't like their tendency to shotgun files all over my filesystem; nor do I like having faith that, if asked to remove the package, they will find them all and delete them. I don't like that they require root priviledges (root priviledges!) to install anything. And I don't like that they're almost never portable; there's one for every operating system and one for every programming language and never mind the fact that every modern operating system hosts more than one programming language.
So we wrote our own and called it toolshelf. toolshelf is a package installer which neither uses packages, nor installs anything. (Why yes, I am feeling a little farklempt, but that's neither here nor there.) It doesn't maintain a package database, it keeps all its files in one place (which you can just blow away if you don't want it anymore), it doesn't need root priviledges, and it is quite portable (in theory, anyway.)
It simply downloads (or clones) what you ask it to, makes its best guess at how to build it, and if that succeeds, makes its best guess at which files are executables and libraries that you care about, and puts those files on the appropriate search paths. Voilà! Sorted.
Ah, I know what you're thinking. You're thinking, that's insane. That's not a real package manager. That's going to fail in so many cases.
All true. And all irrelevant. In fact, it works in a surprising number of cases. It's actually really good for random little projects you find on Github and elsewhere. (It's not like they're ever going to show up in a "real" package manager. And when you get bored with them, you just blow away the clone directory.) And really, the other option is installing from source — and you can just think of toolshelf as an assistant that makes installing from source a lot less painful.
More to the point, it works really well with our projects. It is the recommended way to start using software from Cat's Eye Technologies. Just install toolshelf and then
toolshelf dock @@catseye
and watch it download, build, and install everything.
Even though it was originally only intended for random little projects, I
now regularly dock things like QEMU, Chicken Scheme, and Django with it.
I recently set up two Linux environments for my own use; on each of them,
I installed only maybe a dozen packages from
apt, and I haven't used
pip at all. Most of what I've needed, I've brought in with toolshelf.
Of course, there are still some rough edges — and the way it works, there will always be rough edges — but there is a lot of potential too.
So, check it out!
