NAME
ExtUtils::Install - install files from here to there
SYNOPSIS
use ExtUtils::Install;
install({ 'blib/lib' => 'some/install/dir' } );
uninstall($packlist);
pm_to_blib({ 'lib/Foo/Bar.pm' => 'blib/lib/Foo/Bar.pm' });
DESCRIPTION
Handles the installing and uninstalling of perl modules, scripts, man
pages, etc...
Both install() and uninstall() are specific to the way ExtUtils::Make-
Maker handles the installation and deinstallation of perl modules. They
are not designed as general purpose tools.
On some operating systems such as Win32 installation may not be possi-
ble until after a reboot has occured. This can have varying conse-
quences: removing an old DLL does not impact programs using the new
one, but if a new DLL cannot be installed properly until reboot then
anything depending on it must wait. The package variable
$ExtUtils::Install::MUST_REBOOT
is used to store this status.
If this variable is true then such an operation has occured and any-
thing depending on this module cannot proceed until a reboot has
occured.
If this value is defined but false then such an operation has ocurred,
but should not impact later operations.
Functions
install
install(\%from_to);
install(\%from_to, $verbose, $dont_execute, $uninstall_shadows, $skip);
Copies each directory tree of %from_to to its corresponding value
preserving timestamps and permissions.
There are two keys with a special meaning in the hash: "read" and
"write". These contain packlist files. After the copying is done,
install() will write the list of target files to $from_to{write}.
If $from_to{read} is given the contents of this file will be merged
into the written file. The read and the written file may be identi-
cal, but on AFS it is quite likely that people are installing to a
different directory than the one where the files later appear.
If $verbose is true, will print out each file removed. Default is
false. This is "make install VERBINST=1". $verbose values going up
to 5 show increasingly more diagnostics output.
If $dont_execute is true it will only print what it was going to do
without actually doing it. Default is false.
If $uninstall_shadows is true any differing versions throughout
@INC will be uninstalled. This is "make install UNINST=1"
As of 1.37_02 install() supports the use of a list of patterns to
filter out files that shouldn't be installed. If $skip is omitted
or undefined then install will try to read the list from
INSTALL.SKIP in the CWD. This file is a list of regular expres-
sions and is just like the MANIFEST.SKIP file used by ExtU-
tils::Manifest.
A default site INSTALL.SKIP may be provided by setting then envi-
ronment variable EU_INSTALL_SITE_SKIPFILE, this will only be used
when there isn't a distribution specific INSTALL.SKIP. If the envi-
ronment variable EU_INSTALL_IGNORE_SKIP is true then no install
file filtering will be performed.
If $skip is undefined then the skip file will be autodetected and
used if it is found. If $skip is a reference to an array then it is
assumed the array contains the list of patterns, if $skip is a true
non reference it is assumed to be the filename holding the list of
patterns, any other value of $skip is taken to mean that no install
filtering should occur.
install_default DISCOURAGED
install_default();
install_default($fullext);
Calls install() with arguments to copy a module from blib/ to the
default site installation location.
$fullext is the name of the module converted to a directory (ie.
Foo::Bar would be Foo/Bar). If $fullext is not specified, it will
attempt to read it from @ARGV.
This is primarily useful for install scripts.
NOTE This function is not really useful because of the hard-coded
install location with no way to control site vs core vs vendor
directories and the strange way in which the module name is given.
Consider its use discouraged.
uninstall
uninstall($packlist_file);
uninstall($packlist_file, $verbose, $dont_execute);
Removes the files listed in a $packlist_file.
If $verbose is true, will print out each file removed. Default is
false.
If $dont_execute is true it will only print what it was going to do
without actually doing it. Default is false.
pm_to_blib
pm_to_blib(\%from_to, $autosplit_dir);
pm_to_blib(\%from_to, $autosplit_dir, $filter_cmd);
Copies each key of %from_to to its corresponding value efficiently.
Filenames with the extension .pm are autosplit into the
$autosplit_dir. Any destination directories are created.
$filter_cmd is an optional shell command to run each .pm file
through prior to splitting and copying. Input is the contents of
the module, output the new module contents.
You can have an environment variable PERL_INSTALL_ROOT set which
will be prepended as a directory to each installed file (and direc-
tory).
ENVIRONMENT
PERL_INSTALL_ROOT
Will be prepended to each install path.
EU_INSTALL_IGNORE_SKIP
Will prevent the automatic use of INSTALL.SKIP as the install skip
file.
EU_INSTALL_SITE_SKIPFILE
If there is no INSTALL.SKIP file in the make directory then this
value can be used to provide a default.
