Overview
HgSite is a Mercurial extension that allows serving a dynamic, read-only website using a Mercurial repository as the backend storage. Pages are served by hgweb, the same component that serves the Mercurial repository, and no additional configuration is necessary in the web server.
Current features include:
A subset of the files in the repository are rendered through a number of renderers, based on their path. Built-in renderers include support for Genshi templates, static files and in-repository renderers, and you can also add your own.
It is possible to view a site as it was at any revision, thanks to the consistent versioning of the rendering configuration and all the files composing a site. Have your own Wayback Machine for your site!
Rendered pages have full access to the repository. This allows linking to specific files in the repository browser, including snippets of code in a page (with syntax highlighting), or even implementing a fully custom repository browser.
These features allow a number of interesting use cases, for example:
Serve a README file at the top-level of your repository, GitHub-style.
Serve the web site for a small project directly out of the project's repository. Using a templating engine like Genshi allows writing HTML pages relatively comfortably, as it allows factoring out common parts to avoid duplication. Editing and testing is very easy thanks to the immediate feedback provided by hg serve. And pushing changes to production is as easy as hg push.
Keep the documentation of a project together with the project's code in a single repository, and serve it directly out of the repository. As both are versioned together, it's easy to get the documentation for a specific version of the code. Moreover, the templates have access to all the files in the repository, so the documentation can link to files in the repository browser or inline snippets directly. You could even create a fully custom repository browser.
Run a small blog. The site structure can be done with a few HTML templates, and the articles could be stored as individual files, which could be listed and rendered in the templates.
