[9fans] PUSH sources for Plan 9

[9fans] PUSH sources for Plan 9

[Akshat Kumar]

Are the sources for the PUSH shell
available for Plan 9 proper? It seems
as though it was originally conceived
on Plan 9, then ported to UNIX-compat
systems via P9P. I couldn't find the
Plan 9 sources on the Google Code
repo. It would be nice to just be able
to compile and go.


Thanks,
ak

Yes, I've seen this. This is the port to Plan 9 Ports.
I would like the code for Plan 9. I imagine reproducing
will make things uglier than the original.

Is "broken!" the default prompt, or am I
seeing some error here? A primitive
grep of the source files didn't reveal
any instance of that string, so I wonder...
Also because:

broken! echo hello |< cat >| cat
rc (push): empty argument list
rc (push): empty argument list
term%

Perhaps I should try the test/ dir first...


Thanks!

I've not looked closely at push, but I assume it uses the same /rc/lib/rcmain as, well, rc. See that file for the trick: it sets the prompt to that if your running a $O.out, so you know.

You need filters and the filters need to be set up by default in
rcmain. Anthony is on top of things as usual :) It would be nice to
have other users and if you are interested in exercising it ping me
offlist.

Hi Noah,

I pinged you offline. Not sure if you got my
messages.

It seems that your fan-in operator creates
the pipes, then they're passed along to the
ORF and IRF through argv (via the fan-out
and fan-in respectively). I've checked that
indeed the pipes are being created, by
running push -r ... and subsequently
checking /fd to make sure the corresp.
file descriptors are there. And the '-r'
flag even tells me:
...
Xsimple (../fdcat ) (13 9 5 )
...
Xsimple (echo ) (14 10 6 )
...

and yet, my IRF and ORF programs
don't receive any arguments - the argv
list is empty for both. Any ideas why
this could be?


Thanks,
ak

Hey Akshat,

I received your previous message, I just haven't had time to answer it.

The reason that is failing is because the arguments are one stack
frame above the commands being executed.

The value should be:

Xsimple (echo  14 10 6 )

I promise I'm not ignoring you.
