Want to share your code? Fine!

The policy for all developers wishing to contribute to the Seagull project is that they retain their original copyright, and grant to Demian Turner, the Seagull project maintainer and the Seagull group, a non-exclusive, worldwide, no-cost license to use the works and/or derived works under whatever license is used by the project.

All code must be provided with the standard Code/SeagullHeader notice, and the contributor is expected to list himself as the author of the code at the bottom of the notice.

Submitting Patches

See http://pear.php.net/manual/en/contributing.patches.php for the PEAR guide to creating patches.

To create a patch for Seagull, first you must get the latest code from SVN:


Make your changes …

then change to the Seagull root directory, i.e. if your SGL installation is in /var/www/html/seagull go to that directory with a:

$ cd /var/www/html/seagull

If you created new files in the checked out copy of Seagull you have to add them to svn.

$ svn add path/to/file

then execute:

$ svn diff > your.diff

Please post all patches to the Trac site. If your patch matches an existing ticket, please attach it to that ticket or create a new one accordingly. Next make sure you assign the ticket to the user ‘demian’.

NB: We’ve setup Trac as read-only for anonymous users. To add a patch or create a ticket you will need to sign up on the Seagull site and use the same details to log into Trac.

Create from Seagull Root Directory

Remember, please create all patches from the Seagull root directory!

This is how the patch file header looks like if you create the patch from the root directory:

Index: modules/navigation/classes/CategoryMgr.php
RCS file: /var/cvs/seagull/modules/navigation/classes/CategoryMgr.php,v
retrieving revision 1.14
diff -u -r1.14 CategoryMgr.php
--- modules/navigation/classes/CategoryMgr.php  29 Jan 2005 10:22:28 -0000  1.14
+++ modules/navigation/classes/CategoryMgr.php  2 Feb 2005 12:44:32 -0000
@@ -252,11 +252,11 @@

(the path from line 1 is taken from the root of the SGL directory and is the same to line 6 and 7. If necessary edit this manually)

Diff Only Single File Or Single Directory

In case you only want to diff one directory recursively you may use

$ svn diff modules/publisher > your.diff

Same for only one file:

$ svn diff modules/publisher/lang/german-iso-8859-1.php > your.diff

This is quite handy if you changed something you don’t want to diff.

Use Unix EOL

Also, please remember, especially if you’re submitting a new file, Unix EOL is essential, ie, /n instead of /r/n. If you’re working on Windows and your editor does not have an option to save files with Unix EOL, simple run one of the following one-liners, the 2nd of which also converts tabs to 4 spaces:

perl -pi -e 's/\r\n?/\n/g' $file


tr -d '\15\32' < dos.txt > unix.txt

or with awk

awk '{ sub("\r$", ""); print }' dos.txt > unix.txt

or use the program: dos2unix

Use 4 Spaces Instead Of Tabs

and for tabs to 4 spaces:

tr '\t' '    ' < file > file.new && mv -f file.new file

(may not work, depends on your version of tr)


sed '/\t/    /g' < file > file.new && mv -f file.new file

(depending on your sed version, you may need to type an actual tab char instead of \t)

Patching Seagull

If you want to add a patch to your existing Seagull installation use either the special function for applying patches like built in in phpEclipse or simply type to your linux-console:

$ cd your/seagull/root/directory/
$ patch -p0 --dry-run < your_patch_file.txt

(Note: on FreeBSD patch does not recognize --dry-run option. Use -C or --check as it is equivalent.)

to test, then remove the --dry-run if no errors are reported.
