=head1 NAME
|
|

|
ExtUtils::Install - install files from here to there
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<use ExtUtils::Install;>
|
|
|
|
B<install($hashref,$verbose,$nonono);>
|
|
|
|
B<uninstall($packlistfile,$verbose,$nonono);>
|
|
|
|
B<pm_to_blib($hashref);>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Both install() and uninstall() are specific to the way
|
|
ExtUtils::MakeMaker handles the installation and deinstallation of
|
|
perl modules. They are not designed as general purpose tools.
|
|
|
|
install() takes three arguments. A reference to a hash, a verbose
|
|
switch and a don't-really-do-it switch. The hash ref contains a
|
|
mapping of directories: each key/value pair is a combination of
|
|
directories to be copied. Key is a directory to copy from, value is a
|
|
directory to copy to. The whole tree below the "from" directory will
|
|
be copied preserving timestamps and permissions.
|
|
|
|
There are two keys with a special meaning in the hash: "read" and
|
|
"write". After the copying is done, install will write the list of
|
|
target files to the file named by C<$hashref-E<gt>{write}>. If there is
|
|
another file named by C<$hashref-E<gt>{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, 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 C<FULLEXT> key, like F<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 populated F<blib>
|
|
directory, it will proceed as if the F<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.
