SYNOPSIS
use ExtUtils::Install;
install($hashref,$verbose,$nonono);
uninstall($packlistfile,$verbose,$nonono);
pm_to_blib($hashref);
DESCRIPTION
Both install() and uninstall() are specific to the way
ExtUtils::MakeMaker handles the installation and deinstal
lation of perl modules. They are not designed as general
purpose tools.
install() takes three arguments. A reference to a hash, a
verbose switch and a don't-really-do-it switch. The hash
ref contains a mapping of directories: each key/value pair
is a combination of directories to be copied. Key is a
directory to copy from, value is a directory to copy to.
The whole tree below the "from" directory will be copied
preserving timestamps and permissions.
There are two keys with a special meaning in the hash:
"read" and "write". After the copying is done, install
will write the list of target files to the file named by
"$hashref->{write}". If there is another file named by
"$hashref->{read}", the contents of this file will be
merged into the written file. The read and the written
file may be identical, but on AFS it is quite likely that
people are installing to a different directory than the
one where the files later appear.
install_default() takes one or less arguments. If no
arguments are specified, it takes $ARGV[0] as if it was
specified as an argument. The argument is the value of
MakeMaker's "FULLEXT" key, like Tk/Canvas. This function
calls install() with the same arguments as the defaults
the MakeMaker would use.
The argument-less form is convenient for install scripts
like
perl -MExtUtils::Install -e install_default Tk/Canvas
Assuming this command is executed in a directory with a
populated blib directory, it will proceed as if the blib
was build by MakeMaker on this machine. This is useful
for binary distributions.
uninstall() takes as first argument a file containing
filenames to be unlinked. The second argument is a verbose
switch, the third is a no-don't-really-do-it-now switch.
pm_to_blib() takes a hashref as the first argument and
copies all keys of the hash to the corresponding values
efficiently. Filenames with the extension pm are
autosplit. Second argument is the autosplit directory. If
third argument is not empty, it is taken as a filter
command to be ran on each .pm file, the output of the com
mand being what is finally copied, and the source for
auto-splitting.
You can have an environment variable PERL_INSTALL_ROOT set
which will be prepended as a directory to each installed
file (and directory).
