[9fans] 9p hello world

[-- Attachment #1: Type: text/plain, Size: 383 bytes --]

Dear 9fans,

Looking for a hello world example, between client and server, conversing
with 9p.

A google search for "9p hello world" returned basically nothing.

It seems like there might be a hello world example for libixp ...

http://www.anarchyinthetubes.com/src/hello_libixp

Looking for an example based on plan9port, though.

Any suggestions?

Cheers,
Leonard

here are a few you can google for:

styx-n-9p (Java)
limbo-machine (JavaScript)
go9p (Go)

they include the customary client and server examples. there are
implementations in many other languages; however COBOL and FORTRAN
implementations are currently missing.

Thanks Skip.

Wanted to try 9pclient and 9pserve from plan9port.

go9p looks promising, though.

Compiled and ran go9p/p/clnt/examples/read.go.

Output was ...

2011/09/05 00:40:13 invalid arguments

Success?

try

./read time

a better choice is "cl" client, which lets you navigate the namespace
the file server is serving. the -d flag lets you see what is being
passed around.

$ ../../srv/examples/timefs &
[1] 3681
$ ./read time
Sun Sep  4 22:32:00 PDT 2011$
$ ./cl
9p> ls
time
inftime
9p> cat time
Sun Sep  4 22:32:12 PDT 20119p>
9p> exiting...
$

here's how the plan9port's 9p utility can be used:

% 9p -a tcp!localhost!5640 ls
inftime
time
% 9p -a tcp!localhost!5640 read time
Sun Sep  4 22:32:34 PDT 2011%

I wrote that, but is needing some attention. It is quite old, and
although is still valid, I should finish more examples. Extending it
to p9p's 9p(3) and Inferno's styxserver(10) is in my TODO list, but it
will still be there for a while.

If you write a p9p's hello world server, let me know and I can add it
to that page.

By the way, there probably are more 9p implementations than real
programs using them, but they are not very different. What you really
need to understand is how the protocol works. It's actually quite
simple. Nemo's book includes a very good explanation, which is
completed by the man pages. Also, try to find an existing file server
which matches what you need as much as possible and go on from there.

Compiled and ran "timefs" in the go9p examples.

Wondering now how to do timefs in p9p.

Thought using p9p would be more concise, since it has 9pclient library and
9pserve program.

Wondering how to write a timefs in go, that uses 9pclient and 9pserve.

What is Nemo's book?

a good example app is styxbrowser - an android app. it's based on styx-n-9p.

Nice.

What I'd really like to see is an "addressbookfs" example.

The server stores a list of addresses, in a flat-file, or a database.

The server also provides control-files for CRUD operations.

The server optionally provides html-files, as an interface to CRUD
operations.

Anyone know if such an example exists?

Wondering whether such an example would prove that p9p could replace a LAMP
stack.
