Thanks,

Hey all,
I think it's about time we started a minimalist, statically linked set
of core utilities. The BSD family are bloated, and the GNU monstrous.
Some of us seem to be resorting to using those from Plan 9, which were
designed for another operating system and exist on Unix through a
compatibility shim.
So, in a glorious demonstration of NIH syndrome, let's make our own!
I'm unsure exactly which utilities we should include (suggestions on a
comprehensive set?), but in terms of functionality a good rule of
thumb is to only include flags present in both POSIX and Plan 9, thus
making a sweet little subset. There are exceptions to this, like grep
-q and ls -a, but it's a useful guideline.
I've written a handful so far (basename, cat, echo, false, grep, tee,
touch, true, wc), which I've attached. Each tool is between 6 and 88
SLOC, and compiles with musl into a static binary between 13K and 45K
in size. The manual pages are nice and short, too.
If anyone else wants to contribute a tool written in the same style
they are most welcome. I'd like to set up an hg repo soon, but I'm
quite busy with exams atm.
Thanks,

Nevertheless, the effort already undertaken should at least be preserved in a sbase repository which I asked Connor to set up. For 9base the main purpose is mk and rc (and the assumptions of mk to rely on a rc shell) -- it will be hard to pointless to rewrite those for the sake of 9base. Cheers, Anselm Best regards, Mate

These days it seems a moronic, unproductive crusade on features and rewriting completely serviceable utilities to be much worse is more popular. I completely understand the sentiment. Just the other day on #suckless I was saying, the reason why dwm and dmenu are so good is they bring something new in terms of usability. Things like surf do not, they just have fewer features. So where does this fit in? Okay, this is basically my computing tactic: simplifying my operating system to the point where I can actually understand what on Earth is going on. When I use a system like Ubuntu and Gnome, when shit breaks I have no idea what went wrong, and I tend to end up reinstalling everything. When I use a system like Debian and dwm, when shit breaks I say, ohhh, and fix it, and it takes a couple of seconds. (X is an exception.) The simpler the internals, the easier it is to use, not because of anything on the surface -- though the manuals are rather easier to read -- but because you can clearly visualise the mechanisms inside whatever tools you are using. So I hope that explains my view on the subject. I agree that dwm and friends are suckless at its best, but this sort of paring is necessary to build on my relationship with my computer as a whole: I don't understand how it all works, so instead of spending the next decade creating a mental image of the system, I'll just make my own, thus bringing its complexity within the boundaries of my own ken. (Is that a pun? I don't know.) I don't know how others live with the complexity of their system, but I suspect it involves Perl and duct-tape. :p On 23 May 2011 09:42, Szabolcs Nagy n...@port70.net wrote: scripts will break Yeah, when I started out I wanted to make it entirely POSIX, but once I saw the flaggishness of the POSIX standard I decided I'd just make a compromise. This will begin as a supplement to, rather than a replacement for, standard utilities, and maybe we can get to a point where a static distro like Stali can use only them. I don't know about you, but I could genuinely live without autoconf on my laptop. Thanks, cls

It seems a relatively exhaustive list and - with our case of NIH - we don't want to be using anything from another OS entirely, now do we ;) Some of them, certainly, but we don't need to rewrite everything 9base provides, like sam and mk. My hope is we can find a sufficiently minimalist Unix shell, editor, and so on. If not, I suppose we can write them after the smaller things. We'll see how it goes. 2011/5/23 Kamil Cholewiński harry6...@gmail.com: had a sleepless night, so contributing sleep.c and sleep.1. Thanks Kamil, I'll add them when I create a repo. cls

Re: [dev] sbase
I have a gripe about the fread() business - I have to hit ^D twice
before eof is reported - the first ^D causes fread() to return non-zero,
with text I entered previously, the second ^D causes fread() to return 0.
Probably not a major problem but here's a patch if anyone's interested.
Also rm.c
I don't think it has any problems with symlinks, but I accept no
responsibility for your lost home directory, anime collection or
childhood memories. I've never ever found a use for -f, it's just a
pain having rm prompt me, so I've assumed an always present -f. Stick it
in if you're going for posix or whatever though.
One more thing, we're not bothering with the -- flag, are we?
but I'm quite busy with exams atm.
UK, right? Up late coding even with exams, I'm impressed.
Finally, I have an editor in the works, unfinished, but I plan to show
you lot at some point though/vapourware.
Cheers,
Rob.
