And you've saw first patch there...



I'd say, that i see similar things here (LKML, kernel), wrt shell usage
and text processing.

* checkpatch instead of hard-armed editors (*The* tools of programmers),
with one's (linux, glibc, bash, whatever) source-friendly capabilities
(error/coding-style highlight, easy call-graph, param checking, security
audit(+audit scripts), etc.)

* linux-2.6/scripts/unifdef.c instead of coding style + simple script
(reinventing of compilers is a dream of CS professors of all times :)

* much of te `make` based stuff

* text processing, which is source code processing, if we are in
Open Source, has no place in
+ design (super-macro constructs --> C code),
+ auditing (stupid vmsplice() case *and* first ``fix'')
+ testing (writing source in parallel with constructing userspace
test programs, based on same source; once all is done, script
generates/constructs kernel part)

* and perl is everywhere


On my `sed` scripts i was getting (from Sam):

"Because your shell script is unreadable by normal human beings[*]
while the perl script for people with a bit of perl fu can read it
and fix/modify it.

We want tools that can be maintained and enhanced by most people.

[*] Normal human beings are people with same level of shell
scripting/sed skills that I have just to put that straight."

"Linecount is down but so is maintainability / extendability."

So, no tools or perl is better than nothing?

I don't say, i will solve Andi's quest, i just lost interest. But it is
damn interesting one! One, that many script kiddies will do in minutes,
if they would knew `sed` and a bit of UNIX practice, but not perl, C,
diff, git, etc.
So, teach youngsters about "maintainability / extendability" and "Normal
human beings", or what? OTOH, Who are teachers?

Just two points to show skill mismatch, i.e. for

+ managing/manipulating source,
+ designing, writing, maintaining correct kernel code.

Latter isn't for n00bs, right?

* multi-line grep
Andi Kleen http://mid.gmane.org/20080109000358.GF2117@one.firstfloor.org

* full and correct greping of linux style function definitions
Linus Torvalds http://mid.gmane.org/1054519757.161606@palladium.transmeta.com

All in one shot:

# print linux-style function definitions

sed -n '
/^[^[:blank:]#/].*[),]$/{
/,$/{
:_start;
N;
s=)$=&= ; t_end ; b_start;
:_end;
};
p}' kernel/*c | pager
#_____
One may not know `sed` at all (but i glad to explain and share
everything, i know), *patterns* and expressions are key things.

Once you have approved and try-and-buy tested one, everything else is
pure technical thing. Maybe somebody outstanding (like Rusty) can do that
with CPP, i don't know; `sed` is just more familiar thing for this.

Silence in reply i will understand quite right, i might be wrong. I just
can't see all that stuff not having much skilled people
involved/interested.
