Code Comments, an enhancement for Trac

The problem is two-fold. When reviewing code, it's difficult to associate your comments with their appropriate context. Then, collecting all of these new issues into actionable tickets requires a lot of manual effort.

This plugin allows you to leave comments on top of files, changesets, and attachments. Once you've added all of your comments, you can send them to tickets. These include links to these comments and their description.

It's GitHub, in your Trac.


Pick an .egg file from the Downloads section and place it in the plugins/ directory of your Trac install.

Alternatively build your own egg by checking out the repository and running python bdist_egg in your working copy. Copy the resultant .egg to your plugins directory.

Trac Code Comments plugin requires at least Trac 1.2.

Enable all the modules through the admin web UI or by editing trac.ini.


Install the latest version of the plugin (as above).

Run trac-admin <path-to-environment> upgrade to update the database.

Enable any new modules through the admin web UI or by editing trac.ini.

Run trac-admin <path-to-environment> subscription seed to create subsriptionfor existing attachments, changesets and comments.


  • Comments on files – you can comment on every file in the repository.

  • Inline comments on files – comment on a specific line. The comments appears in context, below the line in question.

  • Comments on changesets – useful when doing code reviews of incoming commits.

  • Inline comments on changesets - comment on a specific line of the changeset.

  • Comments on attachment pages – useful when reviewing patches.

  • Wiki Markup – you can use the standard Trac wiki markup inside your comments.

  • Instant preview – to make sure you get the formatting right.

  • Sending comments to tickets – you can select arbitrary number of comments and create a new ticket out of them. The text of the ticket defaults to links to the comments and their text, but you can edit these before saving the ticket.

  • Comments/ticket cross-reference – to remember which comments are already in tickets and which are not.

  • Notifications – if you have configured Trac to email ticket notifications then comment notifications will just work!

  • Subscriptions – Authors of changesets and attachments, and anyone who creates a comment are subscribed to notifications of comments; to have changeset authors automatically subscribed, your repositories must be configured for synchronisation with Trac

We'd love your help!

If you are a developer, feel free to fork the project here on GitHub, and submit a pull request with your changes.

If you are a designer and have UI suggestions, open an issue, and we'll make sure to address your concerns.

If you want to help with copy, or just wanna say how great or awful we are, creating an issue is the way to go.

You can find help with setting up a local development environment in the HACKING file in this repository.


Nobody can predict the future, but here are some features on the roadmap:

  • Line-level comments for diff attachments, too
  • E-mail notifications
