"Long have we toiled on our tools that interact with CVS. Oh, wait,
you mean we're switching to Subversion? Oh...long have we toiled
on...what,
we're switching to Git?" -The Oppressed Development Tools Maintainer
So, I wanted to write a simple tool that displayed some information
about version-control systems (or "software change management"
systems,
as some are called). I went looking through CPAN, thinking, "Surely,
there must be a single module that can interact with many different
VCSes, right?"
But surprisingly, there wasn't. There was the VCS module, and I
spoke with its maintainer and he said that he'd always wanted to re-
write
it in an object-oriented fashion, but had never found the time to do
so.
So, I wrote VCI, the generic Version Control Interface. Currently
it can display the history and contents of CVS, Subversion, Bazaar,
Mercurial, and Git. It's easy to write new drivers for other VCSes,
you just make a new package in the VCI::VCS namespace. (And if you
read
the VCI code and documentation, you'll see it's easy to write a
driver.)
VCI is object-oriented. It uses Moose.
VCI aims to provide a broad set of features while still working
well with all the different VCSes commonly in use. The rationale,
structure, and functionality of VCI is described in the documentation
of the VCI module.
You can find VCI on the CPAN at:
http://search.cpan.org/dist/VCI/
VCI also has a (currently minimal) homepage at:
http://vci.everythingsolved.com/
VCI is currently alpha-quality. Stability and performance
improvements are coming in the future.
I'm very interested in knowing who's using VCI, and am very
willing to have contributions and new drivers from any programmer who
feels competent enough to design quality code.
You can direct any questions, comments, or patches to me at this
email address.
I hope that you find VCI useful!

I wanted to do a quick install of DBI and DBD::SQLite on a pretty new

fails with a reference to pthread_create. Looking on the web, I found -
pthread, CFLAGS=-pthread and link with -lpthread. I set an env var,

Thank you all.
Use Narthring's method or xhos's method, there is one problem: BEFORE
the calc closed, the programe won't exit. Just like this:
d:\>perl -e "fork or do {system('calc'); exi
t}; $|=1; print 'hello' "
hello
AFTER calc closed, below appears:

hi all
Could any one give me a direction to write a function to match the unix-like
function "od -bc" do.
Now I only get the idea of opening the file.
open(IN, "filename")or die;
my $str=<IN>;
.............
close(IN);
By the way, if the file is a exe or image type, the $str seems don't work
correctly.

Prefer the three-argument form of open.
At least give an indication why the call failed.
open my $in, '<', 'filename'
or die $!;
> my $str=<IN>;
Here, you read only one line from the file.

Study my hexdump example at:
http://www.unur.com/comp/ppp/hexdump.html
You should be able to adapt that to produce the same output od -bc
produces by changing only the hexdump_line subroutine.
Keep in mind:
You must read the input file in binary mode.
Line-by-line processing does not mean much here as you are trying to
display fixed sized blocks of bytes.

Apart from the usual: three-argument "open", lexical filehandles, and=20
explicit '<':
1. if you're dealing with binary files, you must tell perl this:=20
"binmode IN;" after open(...), and
2. you're not reading "strings" of *characters* but "blocks" of *binary* =
data, so better use "read(...)".
so
perldoc -f binmode
perldoc -f read
--=20

Or use the open pragma:
use open IO => ':raw';

CBFalconer's point is that this newsgroup (comp.lang.c, where he and I
are both reading this) is for discussion of the C programming
language. If you want to discuss something other than C, please find
another forum. Massive cross-posts like this are rarely appropriate.

Apparently, having painted himself into a corner, our warrior wants a
few expert roofers to slither up and extricate him.
One of the best experiences that a programmer can have is that of
admitting that the lovingly nurtured brainchild is now terminally ill,
and showing enough fortitude to make a fresh start.

Experts saintly enough to salvage the possibly hopeless would some idea
of whether they are being asked to donate their time to work on a
fundamentally flawed design.

Since Perl, as also most other general purpose languages, has no
plotting primitives or intrinsics,
you will have to use _some_ graphics protocol -- there is no escaping that.
Gnuplot is by no means the only choice, but it is simple and provides
a wide selection of output devices. Your Perl program can write the plot
script to a
file, and call Gnuplot to run that script.

That's not terribly big, you know.
Tell you what - do some legwork, find a relevant forum,
and post your ACTUAL requirment, instead of deciding
you already know the solution.
At the moment, you're being amazingly cryptic
about the problem you're trying to solve,
which has made some people (including me)
suspicious.
