Server-side hooks is a powerful feature that allows you to syntax check code, ensure commit messages are correct, or add the power of automation. You can add pre-commit, post-commit, pre-revprop-change, and post-revprop-change hooks to your Subversion repository.
To add a Server Side Hook to your Assembla repository
In Assembla, for the appropriate repository, click the Settings sub-tab, and then click Server-Side Hooks.
Click Install next to any of the ready-made scripts available from Assembla. You can see a list of available scripts and view the script code in this page.
You can submit your own server-side hook by clicking Propose Your Hook at the bottom of the screen. Assembla receives your request and reviews the submitted code. Once approved, the hook is added to your repository.
