SYNOPSIS
use Attache;
# Create
my $a=Attache->new('alfo_webteam');
# Run a command
$a->lsws() or warn("Problems on lsws");
# Check errors, warnings, output
if($attache->hasErrors()) {
print STDOUT
"completed, with ERRORS:\n",
join("\n", $attache->errors()),"\n";
}
if($attache->hasWarnings()) {
print STDOUT
"completed, with WARNINGS:\n",
join("\n", $attache->warnings()),"\n";
}
print STDOUT "Output:\n",join("\n",$attache->lastoutput()),"\n";
DESCRIPTION
Attache.pm is an OO interface to the ClearCase CLI facility on Win32
systems (attcmd). You need attcmd installed to be able to use this
module.
METHODS
new($ws,[$attcmd])
Constructs a new attache command: takes the workspace as a mandatory
argument. Optional argument is the path to attcmd.
getWs()
returns the curent workspace
setWs($ws)
sets the current workspace
vault()
Returns the local physical location for the current workspace, e.g:
my $a=Attache->new("alfo_dev7");
print $a->vault(),"\n";
# prints F:\home\alf\ClearCase\alfo_dev7 on my machine
lastoutput()
returns the output of the last issued command, as an array of lines
(trailing newlines and CR removed)
hasErrors()
true if the last command had erros
errors()
returns the error diagnostics of the last issued command, as an
array of lines (trailing newlines and CR removed)
hasWarnings()
true if the last command had warnings
warnings()
returns the warning diagnostics of the last issued command, as an
array of lines (trailing newlines and CR removed)
[any_attcmd_command]($argstring)
executes any given attache command, with the given args, for
instance:
my $a=Attache->new("alfo_dev7");
$a->co(' -c "None of your business" /tt_vob/foo/bar/baz.cpp');
Arguments are processed by the shell, so caution with quoting,
special characters etc. should be exercised. DO NOT include any
workspace indication - it is automatically inserted.
Please consult the attache documentation to find out which commands
are supported.
setlog($path,[$appendflag])
Calling setlog directs attache to direct the comand output ti the
given file. If the (optional) $appendflag is true, the file is
opened in append mode and any previous content is preserved, rather
than truncated (the default). Calling
$a->setlog(undef)
Disables logging.
EXPORT
None
INSTALLATION
Just drop in any directory of your INCLUDE path, or read the FindBin
docs and do something along the lines of:
use FindBin qw($Bin);
use lib ($Bin,"$Bin/../perl/lib", "$Bin/../lib/perl","$Bin/../lib");
#
use Attache;
SUPPORTED VERSIONS AND PLATFORMS
Tested with perl 5.6 (ActiveState build 623) on Windows NT. For Unix,
check the Clearcase wrapper on the nearest CPAN site
(
http://search.cpan.org/search?mode=module&query=Clearcase).
Lesser perl versions may work (I'm almost positive about 5.5). Windowze
(non-NT) may also work, but I doubt it, as command.com is even more
broken than cmd.exe .
BUGS AND LIMITATIONS
No effort is made to ensure workspace validity. Setlog should accept
filehandle objects, and it should be possible to log directly to STDOUT
or STDERR.
Due to the cretin way in which cmd.exe handles command line quoting,
some combinations of (legitimate) arguments may break Attache - when
this happens, please direct your grievances to:
Microsoft Corp., Redmond, WA, U.S.A.
Every command starts a new attcmd.exe. If anybody knows a way to use
attcmd over a pipe (or a COM interface, or something else) pls. let me
know.
