[9fans] How can I compile c code written for plan9 in ANIS C compiler

[_ resun]

[-- Attachment #1: Type: text/plain, Size: 435 bytes --]

Hi there!

Is there any way I can compile a C code that is written for plan9 using a ANSI  C compile? Is there any way to replace the plan9 headers with ANSI standard c headers?

Thank you.

the native plan9 c environment is similar to ansi c but has some differences, mainly to the standard libraries.

plan9 also has an ansi/posix environment which is aimed at making it easier to port foreign code.

to use ape, use the pcc command.

there is a fairly complete command line enviroment which you can run ape/psh. this is a subshell which modifies your search path to pick up some different commands.

there is a paper in /sys/doc which describes ape more throughly.

If you look at plan9port (eg, https://9fans.github.io/plan9port/), you'll
see how that's done for a good chunk of the application code of Plan 9
(using host C compilers).
It also includes versions of the Plan 9 libraries that will also compile on
other systems.
Indeed, if you install plan9port you should be able to use its mk, 9c and
9l and mkfile structure to compile your Plan 9 code directly (since that's
how the Plan 9 libraries are compiled in plan9port).
The main restriction is that various Plan 9 C extensions aren't available,
so those need to be removed first.

Well @Charles Forsyth<mailto:charles.forsyth@gmail.com> plan9port has only for unix-like systems I was willing to get them in widows.

Actually there are lots of things from plan9 that I want to use in windows. I was thinking of some substitute for the plan9 libraries for windows. Plan9port has only for unix-like system. Is there any for windows?


Extra: If there isn’t any substitute  for windows, I am interested to contribute to plan9port in near future (probably about a year). Can I do so?

Thank you.

I think there are two ports of plan 9 utilities to windows, one of them 
includes old (2nd ed?), and other one is a more modern port.

re: p9p for windows

Sean Quinlan did a p9p-line port for windows called 9pm, It was seen (it seems) as a port of sam with some simple command line tools
rather than a complete plan9 toolkit. its available here: https://netlib.org/research/ as sam.exe 

There was an attempt at a p9p for windows by Russ Cox, it was a very elegant solution having a p9p dll but suffererd from fragility
(a bug in the dll took all your p9p applications down), and split brain problems (p9p applications understood plan9 style binds and mounts,
native windows applications did not. As a result development stalled.

Its possible that this could be re-awakened using a windows IFS (Installable File System) driver to allow windows applications to see a
plan9 style file structure (the 9: drive :-) and perhaps starting p9p as a windows service. This sounds neat but would be a considerable
amount of work.

This is available here: https://web.archive.org/web/20070221202050/http://swtch.com/usr/local/plan9/9pm/README

There was a later implementation by Michael Teichgräber which is a complete port of plan9ports to windows, in a similar style to the
posix implementations, this works very well, though, like outher p9p implementations it has a bit of a split brain feel to it.

This is here: https://github.com/knieriem/pf9

I took a rather different approach as I used plan9 as my desktop for years but needed windows for some work related applications.

I did a minimal port of the plan9 command line applications to wondows and wrote a cpu(1) line client and server which allowed me to
warp a plan9 terminal to MS windows, in the same directory but running rc(1); I also used remote desktop to get a modern web browser.
This was very comfortable environment for what i needed.

This is here http://www.quintile.net/magic/webls?dir=/quintile.net/pkg      9win.tbz

These days I work on a Mac so plan9ports does all I need, and sadly I hardly ever touch real plan9 any more :-(

Re: [9fans] How can I compile c code written for plan9 in ANIS C compiler

[ron minnich]

we used the coccinnelle tool (spatch) to convert about 1.4M lines of Plan 9
code to C11 for harvey. It was not perfect, but it did get a lot right.

This even got pretty complex: in amd64 Plan 9, r14 and r15 are dedicated to
up and mach.
This is not portable, so we wanted to make it explicit. So in any function
that used up, for example, we had an spatch to add Proc *up = externup();
declaration to those functions. spatch is powerful. references to m->
where replaced with machp().

We also removed the embedded lock structs, with spatches like this:
@  @
expression E;
@@
-incref(E)
+incref(&E->ref)

This actually *maybe* found a bug, in which there was an ambiguity when a
struct contained two embedded lock (e.g. Lock and Qlock) types and the
compiler had to pick the right one to apply the lock/unlock to. It looked
to us like Plan 9 might have picked the wrong one, but we were never sure.

anyway, this is one path to converting plan 9 code. Or you can just go to
https://github.com/Harvey-OS/harvey/tree/GPL-C11, where it already is done.

ah found one. This was for one instance of where mach was used. It
basically says if mach is used in a function, put a declaration of m at the
start of the function.

@mr exists@
typedef Mach; // only needed once per semantic patch
idexpression Mach *m;
function f;
position p;
identifier d;
@@
f@p(...){
<+...
m->d
...+>
}

@@
function mr.f;
position mr.p;
@@

f@p(...) {
++ Mach *m = machp();
...
}

spatch is pretty amazing.
