NAME

Shipwright::Manual::Tutorial - Tutorial to Shipwright

DESCRIPTION

In this tutorial, we'll create a vessel to represent basic stuff of Shipwright.

TUTORIAL

Introduction

Shipwright is shipped with command line tool shipwright which allow you to manage shipwright repositories: create, import dists and "update".

Let's start from a new repository.

Create a new repository

Repository - the backend, where all stuff lives, e.g. metadata, sources, etc... Shipwright supports several backends: SVK, SVN, Git and plain file system. We'll use SVN backend for our repository in this tutorial.

We need to create the svn repo first:

$ svnadmin create /tmp/svnrepo

Then we can initialize the repository of our Shipwright project:

$ shipwright create -r svn:file:///tmp/svnrepo/foo

If svn executable is not under PATH then you can tell shipwright the location of it by setting environment variable "SHIPWRIGHT_SVN". svnadmin is assumed in the same directory as svn.

Don't repeat -r argument

To avoid typing -r svn:file:///tmp/svnrepo/foo all the time you can use "SHIPWRIGHT_REPOSITORY" environment variable.

export SHIPWRIGHT_REPOSITORY="svn:file:///tmp/svnrepo/foo"

Done. No more -r ... for the session.

Import dists into the repository

Our repository is worthless if we don't import some dists. let's do it now.

Shipwright supports different sources you can import things from. Here're some examples:

compressed file
file:/tmp/foo.tar.gz
file:/home/ross/dinosaur-0.01.tar.bz2

Caveat: for files, we only support .tar.gz(.tgz) and .tar.bz2 format currently.

plain directory
dir:/tmp/foo
directory:/home/ross/dinosaur-0.01
HTTP
http://apache.mirror.phpchina.com/httpd/httpd-2.2.9.tar.gz
http://ftp.cuhk.edu.hk/pub/packages/perl/CPAN/authors/id/C/CL/CLKAO/SVK-v2.0.2.tar.gz
FTP
ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.9.tar.bz2
ftp://ftp.cuhk.edu.hk/pub/packages/perl/CPAN/authors/id/C/CL/CLKAO/SVK-v2.0.2.tar.gz
SVK
svk:/test/foo
SVN
svn:file:///tmp/repo/foo
svn:http://svn.example.com/foo
CPAN
cpan:Jifty
cpan:Module::Install

It's ok, Shipwright will find the download link automatically for us, with CPAN's help. thanks, CPAN!

Shipwright
shipwright:svk:/shipwright/repo/foo
shipwright:svk:/shipwright/repo/bar

svk:/shipwright/repo is another shipwright repository, 'foo' or 'bar' is the dist name we want to import.

We'll import apache 2.2.9, perl 5.10, mod_perl 2.0, libxml and XML::LibXML in this tutorial one by one.

$ shipwright import http://www.apache.org/dist/httpd/httpd-2.2.9.tar.gz --name apache
$ shipwright import http://www.cpan.org/authors/id/R/RG/RGARCIA/perl-5.10.0.tar.gz
$ shipwright import http://perl.apache.org/dist/mod_perl-2.0-current.tar.gz --name mod_perl --no-follow
( use --no-follow is because run Makefile.PL will hung if we don't have
  apache installed )
$ shipwright import ftp://xmlsoft.org/libxml2/libxml2-2.6.32.tar.gz --name libxml
$ shipwright import cpan:XML::LibXML

Run shipwright help import to see more options.

As a side note, if we were importing from a source that doesn't use a build mechanism that Shipwright can automatically create a set of build instructions for (currently autoconf, ExtUtils::MakeMaker, Module::Install, and Module::Build), we would now need to edit scripts/DISTNAME/build to tell Shipwright how to build that source.

For our tutorial, e.g. perl 5.10, the build can't be created automatically, so we need to edit the build file:

configure: ./Configure -des -Dprefix=%%INSTALL_BASE%%
test: %%MAKE%% test
install: %%MAKE%% install

For more information on build scripts, see Shipwright::Manual::CustomizeBuild.

update

For dists with CPAN, SVK, SVN, Git and Shipwright types, we can simply use the update cmd to update:

$ shipwright update cpan-XML-LibXML
(yeah, that's right, cpan:XML::LibXML will be named cpan-XML-LibXML)

we can also specify the version we want to update to with --version arg:

$ shipwright update cpan-XML-LibXML --version 1.60

For other types, Shipwright can't find the latest version, so we have to tell Shipwright where it is by relocate cmd.

e.g. apache 2.2.10 is released one day, with download link http://apache.mirror.phpchina.com/httpd/httpd-2.2.10.tar.gz, we need to set the source url first before update.

$ shipwright relocate apache http://www.apache.org/dist/httpd/httpd-2.2.10.tar.gz 
$ shipwright update apache

tweak manually

You may find that cpan-XML-LibXML needs libxml as a dependence, but in /scripts/cpan-XML-LibXML/require.yml there's no such entry, because require.yml is created automatically, filled with perl module dists, no extra dependence will be set.

So we need to do it manually, e.g. use the following cmd to do so

$ shipwright update apache --add-deps libxml

build

We need to check out the repository to some place first, then chdir there, and run:

$ ./bin/shipwright-builder

Run ./bin/shipwright-builder --help to see more options and ./bin/shipwright-builder --advanced-help to see even more options.

For the layout of shipwright's source, see Shipwright.

fiddle the vessel

we can use bin/shipwright-filter to fiddle the vessel, e.g. removing pods. Run ./bin/shipwright-filter --help to see more options

ship our vessel

We call the built stuff the vessel.

To ship our vessel, create an archive of the built files using an archive program such as tar, e.g. by running tar czvf our-vessel.tar.gz /tmp/our-vessel.

Users can use our vessel by extracting the archive to a directory and then adding the following command to their shell's startup script (e.g. for bash users, edit /home/user/.bashrc on most systems): source /base/path/tools/etc/shipwright-source-bash (for bash users). A source script is also provided for the tcsh shell.

Here is a sourcing example:

source /home/user/myapp/tools/shipwright-source-bash /home/user/myapp

This example assumes the myapp vessel was extracted to /home/user/myapp.

After sourcing this script, users will be able to run binaries and load perl modules from our vessel as with normal installed programs, though they will need to start a new shell or re-run their startup script.
