:''This is actually very easy and doesn't require any special knowledge.  However, the more you know about cvs and svn the easier it is.  Many people introduce custom variables into the PKGBUILD that can overcomplicate things.  These are not ''really'' necessary but do help to clarify the syntax of the cvs/svn/git commands, which can appear quite complex.''

abs provides a prototype for cvs, svn, git and darcs. Just do ''pacman -S abs'' and look in ''/usr/share/pacman''.

* With the introduction of the AUR it is most important to avoid using backtick execution to create pkg variables. makepkg will automatically bumps the pkgver anyway when building the package (unless --holdver is used).
** For cvs pkgs you should avoid <code>pkgver=`date +%y%m%d`</code> - this also interferes with the functionality of the AUR. Instead it is still possible to use a date format for the $pkgver variable and to use the cvs -D option to check out code from that date (see below)
+
** For svn you can use the revision number.  An easy way to find the revision number is to use the following command:
+
svn log $_svntrunk --limit 1 | sed -e '/^r/!d' -e 's/^r\([0-9]\+\) .*/\1/;q'
+
That command grabs the most recent log entry from the svn repo and finds the revision number, which is prefixed with an r.  This is from the fluxbox svn log, the revision number is in the top left, r4084

==Example SVN PKGBUILD==
+
 
+
If you use the <tt>source</tt> command on the PKGBUILD first it will store the _svntrunk and _svnmod variables.  So if you run :
+
source PKGBUILD
+
svn info $_svntrunk
+
you can get the revision number(Or,Last Changed Rev) which can be used in pkgver

As you see, I use "-git" suffix in the pkgname, and two variables, _gitroot and _gitname for identify the repositories and the name of the package.
+
I need to introduce an if condition:
+
<pre>
+
if [ -d ${srcdir}/$_gitname ] ; then
+
cd $_gitname && git pull origin
+
msg "The local files are updated."
+
else
+
git clone --depth 1 $_gitroot $_gitname
+
fi
+
</pre>
+
because we have two commands, one for updating source and one for getting it. I copy the source code in a "-build" directory ( the same thing that we do with -cvs and -svn program ).

Prototypes

abs provides a prototype for cvs, svn, git and darcs. Just do pacman -S abs and look in /usr/share/pacman.

A few tips

  • Suffix pkgname with -cvs or -svn or -git where applicable - this prevents confusion with non-development versions e.g. fluxbox-svn or fvwm-cvs vs fluxbox and fvwm.
  • When makepkg is run it will check for newer revisions and then bump pkgver to the latest. If this is not what you want see the --holdver in man makepkg. Note that this only works correctly for cvs and svn, which allow to checkout an older date or revision.
  • You must also be careful about pacman conflicts. For example fluxbox-svn will conflict with fluxbox. In this case you need to use the conflicts= field
conflicts=('fluxbox')
You should also use the provides= field so that pkgs that require fluxbox to be installed recognize your fluxbox-svn pkg as fluxbox
provides=('fluxbox')
You should AVOID using replaces= it generally causes unnecessary problems
  • When using/defining the cvsroot use anonymous:@ rather than anonymous@ to avoid having to press enter to give blank password OR anonymous:password@ - if a password is required.
  • Though it is often unneccesary to use the pkgrel field when building CVS/SVN/GIT pkgs (any changes to the pkg will often be on another day and so are usually accounted for by a change in pkgver [assuming pkgver is used to hold a date format], makepkg will require it.
  • don't forget to include the appropriate vcs tool (cvs,subversion,git,...) in makedepends= as necessary
  • to preserve the integrity of the checked out code it is usually possible to build in a separate build dir e.g. having checked out source code to src/$_cvsmod from $startdir you can use:
  mkdir src/$_cvsmod-build

  cd src/$_cvsmod-build
  ../$_cvsmod/configure

OR if that fails you can try:

  cp -r src/$_cvsmod src/$_cvsmod-build
  cd src/$_cvsmod-build
  • With the introduction of the AUR it is most important to avoid using backtick execution to create pkg variables. makepkg will automatically bumps the pkgver anyway when building the package (unless --holdver is used).
