With the new [[Extras repository process definition|extras process]], [http://mud-builder.garage.maemo.org/ mud-builder] should be re-focused<ref>[https://garage.maemo.org/pipermail/mud-builder-users/2008-June/000255.html MUD Direction?], ''Andrew Flegg'', 26 June 2008</ref> and re-invigorated to help packaging in accordance with the Maemo Packaging Policy<ref>[https://maemo.org/forrest-images/pdf/maemo-policy.pdf Maemo Packaging Policy], ''Eero Tamminen'', 28 May 2008</ref> and [[Uploading to Extras-devel]].

THX that's a great anwesr!

+
-
== Requirements ==
+
-
* Taking an upstream project (from somewhere) and applying zero or more patches for Maemo.
+
-
** Automate creation of projects.
+
-
** Take URL of upstream source deb info page (fish out .dsc, .diff.gz and .tar.gz).
+
-
** Take URL of upstream tarball <strike>done</strike>
+
-
* Provide easy in-life management, e.g. changelogs and maintaining the patch.
+
-
* Proper debification and Maemo additions (like <code>Section: user/</code> and the icon) <strike>done</strike>
+
-
* Conformant with the Maemo Packaging Policy:
+
-
** Any package patched, or not from a existing deb source, needs to have a ''maemo'' version suffix.
+
-
*** For example, if the base version is 7.0, the package version from mud should be '''7.0-0maemo1''' for the first upload, '''7.0-0maemo2''' for the second, etc.
+
-
*** If the upstream package comes from Debian (with version 3.5-7) and is unpatched, the package uploaded from mud is also '''3.5-7'''.
+
-
*** If the upstream package comes from Debian (with version 3.5-7) and ''is'' patched, the package uploaded from mud is '''3.5-7maemo1''' for the first upload, '''3.5-7maemo2''' for the second, etc.
+
-
** Warnings should be given when uploading a package with "Section: user/(.*)" where <code>$1</code> is not in the accepted list.
+
-
** It is an error to try and upload a package with no description.
+
-
* Auto-sign & upload to ...-extras-builder in one-step
+
-
** Use scp to upload all the files, uploading .changes and .dsc ''last'', to avoid auto-builder issues (driven by .dsc files and [https://bugs.maemo.org/show_bug.cgi?id=3354 #3354])
+
-
* Auto-determine Build-Depends <strike>r234</strike>
+
-
 
+
-
== Examples ==
+
-
Create new packages within mud's <code>packages/</code> directory. They can then be manipulated, built, edited and uploaded:
+
-
mud create http://packages.debian.org/source/lenny/cal
+
-
mud create http://packages.ubuntu.com/source/hardy/libgee
+
-
mud create http://download.gnome.org/sources/vala/0.3/vala-0.3.4.tar.bz2
+
-
mud create new-package
+
-
 
+
-
Take a package (for example, from the upstream deb source - in the above case - Ubuntu Hardy), build it; sign it and upload it to diablo-extras-builder:
+
-
mud build libgee
+
-
mud upload libgee
+
-
 
+
-
Typical workflow for getting a package, unpacking the source, editing it, checking the result and then cleaning out the working copy:
+
-
mud get vala
+
-
mud compile vala
+
-
...
+
-
mud diff vala
+
-
...
+
-
mud compile vala
+
-
mud clean vala
+
-
 
+
-
== Workflow ==
+
-
Use quilt<ref>[http://www.suse.de/~agruen/quilt.pdf "Introduction to Quilt", ''Andreas Gr¨unbacher'', June 12 2005</ref>?

== Internals ==
+
-
 
+
-
=== Package structure ===
+
-
Instead of having <code>''package''.xml</code>, <code>patches/''package''.patch</code> and <code>icon/''package''</code>, v2.0 of mud should have more consolidation:
+
-
 
+
-
''package''.pkg/
+
-
  mud.xml - required
+
-
  ''package''.png - optional icon, used if -nn not present
+
-
  ''package''-26.png - optional, if present copied to right place
+
-
  ''package''-64.png - optional, if present copied to right place
+
-
  ''package''.desktop - if present, auto-copied to right place
+
-
  ''package''.service - if present, auto-copied to right place
+
-
  extras.xml- optional specification of file destinations, modes, owners, groups etc.
+
-
  extras/ - copied to ''build-dir''/mud-extras
+
-
    ...
+
-
  patches/ - contains quilt patch set
+
-
    ...
+
-
    ...
+
-
 
+
-
Icon files, desktop and service files are auto-considered part of 'extras' with implicit rules for their destination.
+
-
 
+
-
<pre>
+
-
&lt;extras&gt;
+
-
  &lt;file name="foo.sh"&gt;
+
-
    &lt;destination path="/usr/bin/foo.sh" [mode="auto|0755" ][owner="..."][group="..." ]/&gt;
+
-
    &lt;destination path="/usr/bin/foo2.sh" /&gt;
+
-
  &lt;/file&gt;
+
-
&lt;/extras&gt;
+
-
</pre>
+
-
 
+
-
Mode is optional (set to 0644 if unspecified, unless the file starts #!). Owner and group default to root. <code>install -D</code> lines are auto-added to end of <code>debian/rules:install</code>.
+
-
 
+
-
=== Install steps ===
+
-
# Add extras and extras-devel to /etc/apt/sources.list.d in Scratchbox
+
-
# Install mud.
+
-
# Create <code>~/.mudrc</code> containing garage username and gnupg key to use
+
-
 
+
-
For example:
+
-
/scratchbox/login
+
-
for j in '' '-src'; do for i in '' '-devel'; do
+
-
  echo "deb$j http://repository.maemo.org/extras$i diablo free non-free" >>/etc/apt/sources.list.d/extras-repo.list
+
-
done; done
+
-
apt-get update && apt-get install mud
+
-
cat >~/.mudrc <<EOM
+

USERNAME=jaffa

GPG_KEY=FC11178D

-
EOM
+
-
 
+
-
=== Extras package ===
+
-
mud should be in Extras, and needs dependencies on:
+
-
* xsltproc
+
-
* devscripts
+
-
* gnupg
+
-
* sharutils
+
-
 
+
-
Suggests:
+
-
* imagemagick
+
-
