Build external dependencies for use in CPAN
my $build = Alien::Build->load('./alienfile');
$build->load_requires('configure');
$build->set_prefix('/usr/local');
$build->set_stage('/foo/mystage'); # needs to be absolute
$build->load_requires($build->install_type);
$build->download;
$build->build;
# files are now in /foo/mystage, it is your job (or
# ExtUtils::MakeMaker, Module::Build, etc) to copy
# those files into /usr/local
This module provides tools for building external (non-CPAN) dependencies for CPAN. It is mainly designed to be used at install time of a CPAN client, and work closely with Alien::Base which is used at runtime.
This is the detailed documentation for the Alien::Build class. If you are starting out you probably want to do so from one of these documents:
A broad overview of Alien-Build
and its ecosystem.
Alien::Build::Manual::AlienUser
For users of an Alien::libfoo
that is implemented using Alien::Base.
(The developer of Alien::libfoo
should provide the documentation
necessary, but if not, this is the place to start).
Alien::Build::Manual::AlienAuthor
If you are writing your own Alien based on Alien::Build and Alien::Base.
If you have a common question that has already been answered, like "How do I use alienfile with some build system".
Alien::Build::Manual::PluginAuthor
This is for the brave souls who want to write plugins that will work with Alien::Build + alienfile.
Alien::Build::Manual::Security
If you are concerned that Aliens might be downloading tarballs off the internet, then this is the place for you. This will discuss some of the risks of downloading (really any) software off the internet and will give you some tools to remediate these risks.
Note that you will not usually create a Alien::Build instance directly, but rather be using a thin installer layer, such as Alien::Build::MM (for use with ExtUtils::MakeMaker) or Alien::Build::MB (for use with Module::Build). One of the goals of this project is to remain installer agnostic.
my $build = Alien::Build->new;
This creates a new empty instance of Alien::Build. Normally you will
want to use load
below to create an instance of Alien::Build from
an alienfile recipe.
my $build = Alien::Build->load($alienfile);
This creates an Alien::Build instance with the given alienfile recipe.
my $build = Alien::Build->resume($alienfile, $root);
Load a checkpointed Alien::Build instance. You will need the original
alienfile and the build root (usually _alien
), and a build that
had been properly checkpointed using the checkpoint
method below.
There are three main properties for Alien::Build. There are a number of properties documented here with a specific usage. Note that these properties may need to be serialized into something primitive like JSON that does not support: regular expressions, code references of blessed objects.
If you are writing a plugin (Alien::Build::Plugin) you should use a
prefix like "plugin_name" (where name is the name of your plugin)
so that it does not interfere with other plugin or future versions of
Alien::Build. For example, if you were writing
Alien::Build::Plugin::Fetch::NewProtocol
, please use the prefix
plugin_fetch_newprotocol
:
sub init
{
my($self, $meta) = @_;
$meta->prop( plugin_fetch_newprotocol_foo => 'some value' );
$meta->register_hook(
some_hook => sub {
my($build) = @_;
$build->install_prop->{plugin_fetch_newprotocol_bar} = 'some other value';
$build->runtime_prop->{plugin_fetch_newprotocol_baz} = 'and another value';
}
);
}
If you are writing a alienfile recipe please use the prefix my_
:
use alienfile;
meta_prop->{my_foo} = 'some value';
probe sub {
my($build) = @_;
$build->install_prop->{my_bar} = 'some other value';
$build->install_prop->{my_baz} = 'and another value';
};
Any property may be used from a command:
probe [ 'some command %{.meta.plugin_fetch_newprotocol_foo}' ];
probe [ 'some command %{.install.plugin_fetch_newprotocol_bar}' ];
probe [ 'some command %{.runtime.plugin_fetch_newprotocol_baz}' ];
probe [ 'some command %{.meta.my_foo}' ];
probe [ 'some command %{.install.my_bar}' ];
probe [ 'some command %{.runtime.my_baz}' ];
my $href = $build->meta_prop;
my $href = Alien::Build->meta_prop;
Meta properties have to do with the recipe itself, and not any particular
instance that probes or builds that recipe. Meta properties can be changed
from within an alienfile using the meta_prop
directive, or from
a plugin from its init
method (though should NOT be modified from any
hooks registered within that init
method). This is not strictly enforced,
but if you do not follow this rule your recipe will likely be broken.
arch
This is a hint to an installer like Alien::Build::MM or Alien::Build::MB, that the library or tool contains architecture dependent files and so should be stored in an architecture dependent location. If not specified by your alienfile then it will be set to true.
check_digest
True if cryptographic digest should be checked when files are fetched or downloaded. This is set by Digest negotiator plugin.
destdir
Some plugins (Alien::Build::Plugin::Build::Autoconf for example) support
installing via DESTDIR
. They will set this property to true if they
plan on doing such an install. This helps Alien::Build find the staged
install files and how to locate them.
If available, DESTDIR
is used to stage install files in a sub directory before
copying the files into blib
. This is generally preferred method
if available.
destdir_filter
Regular expression for the files that should be copied from the DESTDIR
into the stage directory. If not defined, then all files will be copied.
destdir_ffi_filter
Same as destdir_filter
except applies to build_ffi
instead of build
.
digest
This properties contains the cryptographic digests (if any) that should
be used when verifying any fetched and downloaded files. It is a hash
reference where the key is the filename and the value is an array
reference containing a pair of values, the first being the algorithm
('SHA256' is recommended) and the second is the actual digest. The
special filename *
may be specified to indicate that any downloaded
file should match that digest. If there are both real filenames and
the *
placeholder, the real filenames will be used for filenames
that match and any other files will use the placeholder. Example:
$build->meta_prop->{digest} = {
'foo-1.00.tar.gz' => [ SHA256 => '9feac593aa49a44eb837de52513a57736457f1ea70078346c60f0bfc5f24f2c1' ],
'foo-1.01.tar.gz' => [ SHA256 => '6bbde6a7f10ae5924cf74afc26ff5b7bc4b4f9dfd85c6b534c51bd254697b9e7' ],
'*' => [ SHA256 => '33a20aae3df6ecfbe812b48082926d55391be4a57d858d35753ab1334b9fddb3' ],
};
Cryptographic signatures will only be checked if the check_digest meta property is set and if the Digest negotiator plugin is loaded. (The Digest negotiator can be used directly, but is also loaded automatically if you use the digest directive is used by the alienfile).
env
Environment variables to override during the build stage.
env_interpolate
Environment variable values will be interpolated with helpers. Example:
meta->prop->{env_interpolate} = 1;
meta->prop->{env}->{PERL} = '%{perl}';
local_source
Set to true if source code package is available locally. (that is not fetched
over the internet). This is computed by default based on the start_url
property. Can be set by an alienfile or plugin.
platform
Hash reference. Contains information about the platform beyond just $^O
.
platform.compiler_type
Refers to the type of flags that the compiler accepts. May be expanded in the future, but for now, will be one of:
microsoft
On Windows when using Microsoft Visual C++
unix
Virtually everything else, including gcc on windows.
The main difference is that with Visual C++ -LIBPATH
should be used instead
of -L
, and static libraries should have the .LIB
suffix instead of .a
.
platform.system_type
$^O
is frequently good enough to make platform specific logic in your
alienfile, this handles the case when $^O can cover platforms that provide
multiple environments that Perl might run under. The main example is windows,
but others may be added in the future.
Note that cygwin
and msys
are considered unix
even though they run
on windows!
platform.cpu.count
Contains a non-negative integer of available (possibly virtual) CPUs on the
system. This can be used by build plugins to build in parallel. The environment
variable ALIEN_CPU_COUNT
can be set to override the CPU count.
platform.cpu.arch.name
Contains a normalized name for the architecture of the current Perl. This can be used by fetch plugins to determine which binary packages to download. The value may be one of the following, but this list will be expanded as needed.
armel
32-bit ARM soft-float
armhf
32-bit ARM hard-float
aarch64
64-bit ARM
ppc
32-bit PowerPC (big-endian)
ppc64
64-bit PowerPC (big-endian)
x86
32-bit Intel (i386, i486, i686)
x86_64
64-bit Intel (AMD64)
unknown
Unable to detect architecture. Please report this if needed.
out_of_source
Build in a different directory from the where the source code is stored.
In autoconf this is referred to as a "VPATH" build. Everyone else calls this
an "out-of-source" build. When this property is true, instead of extracting
to the source build root, the downloaded source will be extracted to an source
extraction directory and the source build root will be empty. You can use the
extract
install property to get the location of the extracted source.
network
True if a network fetch is available. This should NOT be set by an alienfile
or plugin. This is computed based on the ALIEN_INSTALL_NETWORK
environment
variables.
start_url
The default or start URL used by fetch plugins.
my $href = $build->install_prop;
Install properties are used during the install phase (either
under share
or system
install). They are remembered for
the entire install phase, but not kept around during the runtime
phase. Thus they cannot be accessed from your Alien::Base
based module.
autoconf_prefix
The prefix as understood by autoconf. This is only different on Windows
Where MSYS is used and paths like C:/foo
are represented as /C/foo
which are understood by the MSYS tools, but not by Perl. You should
only use this if you are using Alien::Build::Plugin::Build::Autoconf in
your alienfile. This is set during before the
build hook is run.
download
The location of the downloaded archive (tar.gz, or similar) or directory. This will be undefined until the archive is actually downloaded.
download_detail
This property contains optional details about a downloaded file. This property is populated by Alien::Build core. This property is a hash reference. The key is the path to the file that has been downloaded and the value is a hash reference with additional detail. All fields are optional.
download_detail.digest
This, if available, with the cryptographic signature that was successfully
matched against the downloaded file. It is an array reference with a
pair of values, the algorithm (typically something like SHA256
) and
the digest.
download_detail.protocol
This, if available, will be the URL protocol used to fetch the downloaded file.
env
Environment variables to override during the build stage. Plugins are free to set additional overrides using this hash.
extract
The location of the last source extraction. For a "out-of-source" build
(see the out_of_source
meta property above), this will only be set once.
For other types of builds, the source code may be extracted multiple times,
and thus this property may change.
old
[deprecated]
Hash containing information on a previously installed Alien of the same name, if available. This may be useful in cases where you want to reuse the previous install if it is still sufficient.
old.prefix
[deprecated]
The prefix for the previous install. Versions prior to 1.42 unfortunately
had this in typo form of preifx
.
old.runtime
[deprecated]
The runtime properties from the previous install.
patch
Directory with patches, if available. This will be undef
if there
are no patches. When initially installing an alien this will usually
be a sibling of the alienfile
, a directory called patch
. Once
installed this will be in the share directory called _alien/patch
.
The former is useful for rebuilding an alienized package using
af.
prefix
The install time prefix. Under a destdir
install this is the
same as the runtime or final install location. Under a non-destdir
install this is the stage
directory (usually the appropriate
share directory under blib
).
root
The build root directory. This will be an absolute path. It is the
absolute form of ./_alien
by default.
stage
The stage directory where files will be copied. This is usually the root of the blib share directory.
system_probe_class
After the probe step this property may contain the plugin class that
performed the system probe. It shouldn't be filled in directly by
the plugin (instead if should use the hook property probe_class
,
see below). This is optional, and not all probe plugins will provide
this information.
system_probe_instance_id
After the probe step this property may contain the plugin instance id that
performed the system probe. It shouldn't be filled in directly by
the plugin (instead if should use the hook property probe_instance_id
,
see below). This is optional, and not all probe plugins will provide
this information.
my $href = $build->plugin_instance_prop($plugin);
This returns the private plugin instance properties for a given plugin. This method should usually only be called internally by plugins themselves to keep track of internal state. Because the content can be used arbitrarily by the owning plugin because it is private to the plugin, and thus is not part of the Alien::Build spec.
my $href = $build->runtime_prop;
Runtime properties are used during the install and runtime phases
(either under share
or system
install). This should include
anything that you will need to know to use the library or tool
during runtime, and shouldn't include anything that is no longer
relevant once the install process is complete.
alien_build_version
The version of Alien::Build used to install the library or tool.
alt
Alternate configurations. If the alienized package has multiple libraries this could be used to store the different compiler or linker flags for each library. Typically this will be set by a plugin in the gather stage (for either share or system installs).
cflags
The compiler flags. This is typically set by a plugin in the gather stage (for either share or system installs).
cflags_static
The static compiler flags. This is typically set by a plugin in the gather stage (for either share or system installs).
command
The command name for tools where the name my differ from platform to
platform. For example, the GNU version of make is usually make
in
Linux and gmake
on FreeBSD. This is typically set by a plugin in the
gather stage (for either share or system installs).
ffi_name
The name DLL or shared object "name" to use when searching for dynamic
libraries at runtime. This is passed into FFI::CheckLib, so if
your library is something like libarchive.so
or archive.dll
you
would set this to archive
. This may be a string or an array of
strings. This is typically set by a plugin in the gather stage
(for either share or system installs).
ffi_checklib
This property contains two sub properties:
ffi_checklib.share
$build->runtime_prop->{ffi_checklib}->{share} = [ ... ];
Array of additional FFI::CheckLib flags to pass in to find_lib
for a share
install.
ffi_checklib.system
Array of additional FFI::CheckLib flags to pass in to find_lib
for a system
install.
Among other things, useful for specifying the try_linker_script
flag:
$build->runtime_prop->{ffi_checklib}->{system} = [ try_linker_script => 1 ];
This is typically set by a plugin in the gather stage (for either share or system installs).
inline_auto_include
[version 2.53]
This property is an array reference of C code that will be passed into Inline::C to make sure that appropriate headers are automatically included. See "auto_include" in Inline::C for details.
install_type
The install type. This is set by AB core after the probe hook is executed. Is one of:
system
For when the library or tool is provided by the operating system, can be
detected by Alien::Build, and is considered satisfactory by the
alienfile
recipe.
share
For when a system install is not possible, the library source will be downloaded from the internet or retrieved in another appropriate fashion and built.
libs
The library flags. This is typically set by a plugin in the gather stage (for either share or system installs).
libs_static
The static library flags. This is typically set by a plugin in the gather stage (for either share or system installs).
perl_module_version
The version of the Perl module used to install the alien (if available).
For example if Alien::curl is installing libcurl
this would be the
version of Alien::curl used during the install step.
prefix
The final install root. This is usually they share directory.
version
The version of the library or tool. This is typically set by a plugin in the gather stage (for either share or system installs).
my $href = $build->hook_prop;
Hook properties are for the currently running (if any) hook. They are
used only during the execution of each hook and are discarded after.
If no hook is currently running then hook_prop
will return undef
.
name
The name of the currently running hook.
version (probe)
Probe and PkgConfig plugins may set this property indicating the version of the alienized package. Not all plugins and configurations may be able to provide this.
probe_class (probe)
Probe and PkgConfig plugins may set this property indicating the
plugin class that made the probe. If the probe results in a system
install this will be propagated to system_probe_class
for later
use.
probe_instance_id (probe)
Probe and PkgConfig plugins may set this property indicating the
plugin instance id that made the probe. If the probe results in a
system install this will be propagated to system_probe_instance_id
for later use.
$build->checkpoint;
Save any install or runtime properties so that they can be reloaded on
a subsequent run in a separate process. This is useful if your build
needs to be done in multiple stages from a Makefile
, such as with
ExtUtils::MakeMaker. Once checkpointed you can use the resume
constructor (documented above) to resume the probe/build/install]
process.
my $dir = $build->root;
This is just a shortcut for:
my $root = $build->install_prop->{root};
Except that it will be created if it does not already exist.
my $type = $build->install_type;
This will return the install type. (See the like named install property
above for details). This method will call probe
if it has not already
been called.
my $rule = $build->download_rule;
This returns install rule as a string. This is determined by the environment and should be one of:
warn
Warn only if fetching via non secure source (secure sources include https
,
and bundled files, may include other encrypted protocols in the future).
digest
Require that any downloaded source package have a cryptographic signature in the alienfile and that signature matches what was downloaded.
encrypt
Require that any downloaded source package is fetched via secure source.
digest_or_encrypt
Require that any downloaded source package is either fetched via a secure source or has a cryptographic signature in the alienfile and that signature matches what was downloaded.
digest_and_encrypt
Require that any downloaded source package is both fetched via a secure source and has a cryptographic signature in the alienfile and that signature matches what was downloaded.
The current default is warn
, but in the near future this will be upgraded to
digest_or_encrypt
.
$build->set_prefix($prefix);
Set the final (unstaged) prefix. This is normally only called by Alien::Build::MM and similar modules. It is not intended for use from plugins or from an alienfile.
$build->set_stage($dir);
Sets the stage directory. This is normally only called by Alien::Build::MM and similar modules. It is not intended for use from plugins or from an alienfile.
my $hash = $build->requires($phase);
Returns a hash reference of the modules required for the given phase. Phases include:
configure
These modules must already be available when the alienfile is read.
any
These modules are used during either a system
or share
install.
share
These modules are used during the build phase of a share
install.
system
These modules are used during the build phase of a system
install.
$build->load_requires($phase);
This loads the appropriate modules for the given phase (see requires
above
for a description of the phases).
my $install_type = $build->probe;
Attempts to determine if the operating system has the library or
tool already installed. If so, then the string system
will
be returned and a system install will be performed. If not,
then the string share
will be installed and the tool or
library will be downloaded and built from source.
If the environment variable ALIEN_INSTALL_TYPE
is set, then that
will force a specific type of install. If the detection logic
cannot accommodate the install type requested then it will fail with
an exception.
$build->download;
Download the source, usually as a tarball, usually from the internet.
Under a system
install this does not do anything.
my $res = $build->fetch;
my $res = $build->fetch($url, %options);
Fetch a resource using the fetch hook. Returns the same hash structure described below in the fetch hook documentation.
[version 2.39]
As of Alien::Build 2.39, these options are supported:
http_headers
my $res = $build->fetch($url, http_headers => [ $key1 => $value1, $key2 => $value 2, ... ]);
Set the HTTP request headers on all outgoing HTTP requests. Note that not all protocols or fetch plugins support setting request headers, but the ones that do not should issue a warning if you try to set request headers and they are not supported.
[experimental]
my $bool = $build->check_digest($path);
Checks any cryptographic signatures for the given file. The
file is specified by $path
which may be one of:
string
Containing the path to the file to be checked.
Containing the path to the file to be checked.
HASH
A Hash reference containing information about a file. See the fetch hook for details on the format.
Returns true if the cryptographic signature matches, false if cryptographic signatures are disabled. Will throw an exception if the signature does not match, or if no plugin provides the correct algorithm for checking the signature.
my $decoded_res = $build->decode($res);
Decode the HTML or file listing returned by fetch
. Returns the same
hash structure described below in the
decode hook documentation.
my $sorted_res = $build->prefer($res);
Filter and sort candidates. The preferred candidate will be returned first in the list. The worst candidate will be returned last. Returns the same hash structure described below in the prefer hook documentation.
my $dir = $build->extract;
my $dir = $build->extract($archive);
Extracts the given archive into a fresh directory. This is normally called internally to Alien::Build, and for normal usage is not needed from a plugin or alienfile.
$build->build;
Run the build step. It is expected that probe
and download
have already been performed. What it actually does depends on the
type of install:
share
The source is extracted, and built as determined by the alienfile
recipe. If there is a gather_share
that will be executed last.
system
The gather_system hook will be executed.
$build->test;
Run the test phase
$build->clean_install
Clean files from the final install location. The default implementation removes all
files recursively except for the _alien
directory. This is helpful when you have
an old install with files that may break the new build.
For a non-share install this doesn't do anything.
$build->system($command);
$build->system($command, @args);
Interpolates the command and arguments and run the results using
the Perl system
command.
$build->log($message);
Send a message to the log. By default this prints to STDOUT
.
my $meta = Alien::Build->meta;
my $meta = $build->meta;
Returns the meta object for your Alien::Build class or instance. The
meta object is a way to manipulate the recipe, and so any changes to the
meta object should be made before the probe
, download
or build
steps.
my $href = $build->meta->prop;
Meta properties. This is the same as calling meta_prop
on
the class or Alien::Build instance.
Alien::Build->meta->add_requires($phase, $module => $version, ...);
Add the requirement to the given phase. Phase should be one of:
my $interpolator = $build->meta->interpolator;
my $interpolator = Alien::Build->interpolator;
Returns the Alien::Build::Interpolate instance for the Alien::Build class.
my $bool = $build->meta->has_hook($name);
my $bool = Alien::Build->has_hook($name);
Returns if there is a usable hook registered with the given name.
$build->meta->register_hook($name, $instructions);
Alien::Build->meta->register_hook($name, $instructions);
Register a hook with the given name. $instruction
should be either
a code reference, or a command sequence, which is an array reference.
$build->meta->default_hook($name, $instructions);
Alien::Build->meta->default_hook($name, $instructions);
Register a default hook, which will be used if the alienfile does not register its own hook with that name.
$build->meta->around_hook($hook_name, $code);
Alien::Build->meta->around_hook($hook_name, $code);
Wrap the given hook with a code reference. This is similar to a Moose method modifier, except that it wraps around the given hook instead of a method. For example, this will add a probe system requirement:
$build->meta->around_hook(
probe => sub {
my $orig = shift;
my $build = shift;
my $type = $orig->($build, @_);
return $type unless $type eq 'system';
# also require a configuration file
if(-f '/etc/foo.conf')
{
return 'system';
}
else
{
return 'share';
}
},
);
$build->meta->after_hook($hook_name, sub {
my(@args) = @_;
...
});
Execute the given code reference after the hook. The original arguments are passed into the code reference.
$build->meta->before_hook($hook_name, sub {
my(@args) = @_;
...
});
Execute the given code reference before the hook. The original arguments are passed into the code reference.
Alien::Build->meta->apply_plugin($name);
Alien::Build->meta->apply_plugin($name, @args);
Apply the given plugin with the given arguments.
Alien::Build responds to these environment variables:
ALIEN_BUILD_LOG
The default log class used. See Alien::Build::Log and Alien::Build::Log::Default.
ALIEN_BUILD_PKG_CONFIG
Override the logic in Alien::Build::Plugin::PkgConfig::Negotiate which
chooses the best pkg-config
plugin.
ALIEN_BUILD_POSTLOAD
semicolon separated list of plugins to automatically load after parsing your alienfile.
ALIEN_BUILD_PRELOAD
semicolon separated list of plugins to automatically load before parsing your alienfile.
ALIEN_BUILD_RC
Perl source file which can override some global defaults for Alien::Build, by, for example, setting preload and postload plugins.
ALIEN_DOWNLOAD_RULE
This value determines the rules by which types of downloads are allowed. The legal
values listed under "download_rule", plus default
which will be the default for
the current version of Alien::Build. For this version that default is warn
.
ALIEN_INSTALL_NETWORK
If set to true (the default), then network fetch will be allowed. If set to false, then network fetch will not be allowed.
What constitutes a local vs. network fetch is determined based on the start_url
and local_source
meta properties. An alienfile or plugin could
override
this detection (possibly inappropriately), so this variable is not a substitute
for properly auditing of Perl modules for environments that require that.
ALIEN_INSTALL_TYPE
If set to share
or system
, it will override the system detection logic.
If set to default
, it will use the default setting for the alienfile.
The behavior of other values is undefined.
Although the recommended way for a consumer to use an Alien::Base based Alien is to declare it as a static configure and build-time dependency, some consumers may prefer to fallback on using an Alien only when the consumer itself cannot detect the necessary package. In some cases the consumer may want the user to opt-in to using an Alien before requiring it.
To keep the interface consistent among Aliens, the consumer of the fallback opt-in
Alien may fallback on the Alien if the environment variable ALIEN_INSTALL_TYPE
is set to any value. The rationale is that by setting this environment variable the
user is aware that Alien modules may be installed and have indicated consent.
The actual implementation of this, by its nature would have to be in the consuming
CPAN module.
DESTDIR
This environment variable will be manipulated during a destdir install.
PKG_CONFIG
This environment variable can be used to override the program name for pkg-config
when using the command line plugin: Alien::Build::Plugin::PkgConfig::CommandLine.
ftp_proxy, all_proxy
If these environment variables are set, it may influence the Download negotiation plugin Alien::Build::Plugin::Download::Negotiate. Other proxy variables may be used by some Fetch plugins, if they support it.
The intent of the Alien-Build
team is to support the same versions of
Perl that are supported by the Perl toolchain. As of this writing that
means 5.16 and better.

Alien::Base was originally written by Joel Berger, the rest of this project would not have been possible without him getting the project started. Thanks to his support I have been able to augment the original Alien::Base system with a reliable set of tools (Alien::Build, alienfile, Test::Alien), which make up this toolset.
The original Alien::Base is still copyright (c) 2012-2020 Joel Berger. It has
the same license as the rest of the Alien::Build and related tools distributed as
Alien-Build
. Joel Berger thanked a number of people who helped in in the development
of Alien::Base, in the documentation for that module.
I would also like to acknowledge the other members of the PerlAlien github organization, Zakariyya Mughal (sivoais, ZMUGHAL) and mohawk (ETJ). Also important in the early development of Alien::Build were the early adopters Chase Whitener (genio, CAPOEIRAB, author of Alien::libuv), William N. Braswell, Jr (willthechill, WBRASWELL, author of Alien::JPCRE2 and Alien::PCRE2) and Ahmad Fatoum (a3f, ATHREEF, author of Alien::libudev and Alien::LibUSB).
The Alien ecosystem owes a debt to Dan Book, who goes by Grinnz on IRC, for answering question about how to use Alien::Build and friends.
