Welcome to Trac Hacks

The purpose of TracHacks is to provide free Subversion hosting for community created Trac hacks.

TracHacks uses the excellent TagsPlugin, which adds basic categorisation to Trac. All hacks are tagged with one or more of the available tags?.

How to Contribute

I've tried to make this as simple as possible:

  1. Register a user name then login (requires cookies).
  2. Fill out the NewHack form.
  3. Verify all the details for your new page are correct.
  4. Commit your code to the provided Subversion URL
    (alternatively you can simply attach your hack to your Wiki page, ala MacroBazaar, but remember that you can't delete or replace attachments)
  5. Have a look at TracHackDevelopment.
  6. Consider subscribing to the trac-hacks mailing list.

The TracHacks page contains more information, contact details, bug reports, enhancements, suggestions, etc.

I host my own hack elsewhere

Feel free to create a stub page here with a short description and links to your own hack. Please stick to the page naming convention, by appending the hack type (eg. GanttPlugin)

eg. The DoStuff macro would become the page DoStuffMacro.

Once you have created your page, tag it with the hack type and it will appear on the front page. Tag it with your TracHacks user id if you want it to show up on your user page.
