Who wants to meet a zombie anyway?

Subject: [PATCH 3/3] [kconfig] Direct use of lxdialog routines by menuconfig
Date: Mon, 12 Dec 2005 01:46:06 +0100

After three years, the zombie walks again!  This patch (against the latest
git tree) cleans up interaction between kconfig's mconf (menuconfig
frontend) and lxdialog. Its commandline interface disappears in this patch,
instead a .so is packed from the lxdialog objects and the relevant
functions are called directly from mconf.

Not build per se, but perl mind share of the people. Did they ever
looked into `strace`, when running (kind of) `perl simple-regex`?

Maybe there weren't right people to manage things easily in shell?
Reinventing parser was a major step back, whatever anyone can say.

I dislike seeing arguments that this is not easy/possible in shell based
parsers. If the chosen technology does not fit the problem domain
then it's about time to shift technology.

I use them exclusively.

It is far and away the most convenient parsing - just to do "make
oldconfig"  (possibly by making changes by hand to the .config file
first).

As far as I'm personally concerned, the shell parsers are the _only_
parser that really matter. So if you want to replace them with something
else, that something else had better be pretty much perfect and not take
all that long to build.

That was a rhetoric (i guess) statement. But it *is* used to
configure/build almost all tools, currently directly or indirectly
kbuild/kconfig uses.

`m4 'make "shell"'`

*OR*

`To quote lguest 'To quote David Wheeler:

"Any problem in computer science can be solved with
 another layer of indirection."'`

That's my personal view. And after 5-6 years of the "development", i
can see the "results". Again, will see.
