installdirs¶

The default destinations for these installable things come from entries in your system's configuration. You can select from three different sets of default locations by setting the "installdirs" parameter as follows:

                          'installdirs' set to:
                   core          site                vendor
              uses the following defaults from ExtUtils::Config:
  lib     => installprivlib  installsitelib      installvendorlib
  arch    => installarchlib  installsitearch     installvendorarch
  script  => installscript   installsitescript   installvendorscript
  bin     => installbin      installsitebin      installvendorbin
  bindoc  => installman1dir  installsiteman1dir  installvendorman1dir
  libdoc  => installman3dir  installsiteman3dir  installvendorman3dir
  binhtml => installhtml1dir installsitehtml1dir installvendorhtml1dir [*]
  libhtml => installhtml3dir installsitehtml3dir installvendorhtml3dir [*]
  * Under some OS (eg. MSWin32) the destination for HTML documents is determined by the C<Config.pm> entry C<installhtmldir>.

The default value of "installdirs" is "site".

install_base¶

You can also set the whole bunch of installation paths by supplying the "install_base" parameter to point to a directory on your system. For instance, if you set "install_base" to "/home/ken" on a Linux system, you'll install as follows:

  lib     => /home/ken/lib/perl5
  arch    => /home/ken/lib/perl5/i386-linux
  script  => /home/ken/bin
  bin     => /home/ken/bin
  bindoc  => /home/ken/man/man1
  libdoc  => /home/ken/man/man3
  binhtml => /home/ken/html
  libhtml => /home/ken/html

prefix¶

This sets a prefix, identical to ExtUtils::MakeMaker's PREFIX option. This does something similar to "install_base" in a much more complicated way.

config()¶

The ExtUtils::Config object used for this object.

verbose¶

The verbosity of ExtUtils::InstallPaths. It defaults to 0

create_packlist¶

Together with "module_name" this controls whether a packlist will be added; it defaults to 1.

dist_name¶

The name of the current module.

module_name¶

The name of the main module of the package. This is required for packlist creation, but in the future it may be replaced by dist_name. It defaults to "dist_name =~ s/-/::/gr" if dist_name is set.

destdir¶

If you want to install everything into a temporary directory first (for instance, if you want to create a directory tree that a package manager like "rpm" or "dpkg" could create a package from), you can use the "destdir" parameter. E.g. Setting "destdir" to "/tmp/foo" will effectively install to "/tmp/foo/$sitelib", "/tmp/foo/$sitearch", and the like, except that it will use "File::Spec" to make the pathnames work correctly on whatever platform you're installing on.

new¶

Create a new ExtUtils::InstallPaths object. All attributes are valid arguments to the constructor, as well as this:

• install_path

  This must be a hashref with the type as keys and the destination as values.

• install_base_relpaths

  This must be a hashref with types as keys and a path relative to the install_base as value.

• prefix_relpaths

  This must be a hashref any of these three keys: core, vendor, site. Each of the values mush be a hashref with types as keys and a path relative to the prefix as value. You probably want to make these three hashrefs identical.

• original_prefix

  This must be a hashref with the legal installdirs values as keys and the prefix directories as values.

• install_sets

  This mush be a hashref with the legal installdirs are keys, and the values being hashrefs with types as keys and locations as values.

install_map()¶

Return a map suitable for use with ExtUtils::Install. In most cases, this is the only method you'll need.

install_destination($type)¶

Returns the destination of a certain type.

install_types()¶

Return a list of all supported install types in the current configuration.

is_default_installable($type)¶

Given a file type, will return true if the file type would normally be installed when neither install-base nor prefix has been set. I.e. it will be true only if the path is set from the configuration object or set explicitly by the user via install_path.

install_path($type)¶

Gets the install path for a certain type.

install_sets($installdirs, $type)¶

Get the path for a certain $type with a certain $installdirs.

install_base_relpaths($type, $relpath)¶

Get the relative paths for use with install_base for a certain type.

prefix_relative($installdirs, $type)¶

Gets the path of a certain $type and $installdirs relative to the prefix.

prefix_relpaths($install_dirs, $type)¶

Get the default relative path to use in case the config install paths cannot be prefixified. You do not want to use this to get any relative path, but may require it to set it for custom types.

original_prefix($installdirs)¶

Get the original prefix for a certain type of $installdirs.
