Stat is a static site generator and an example of how the Longform Markup Language can be used. The setup is very primitive at the moment. To get a feel for what a codebase made using Stat looks like have a look through Stat's repo, especially the _src directory.
To use this project, clone the repo and then run deno task create /path/to/new/project. From the newly created project you can now run deno task dev and a server will build your application into the _dev directory and serve your application locally.
Stat is currently only setup to deploy to Codeberg pages when using a custom domain. Make sure your branch name is called pages and follow Codeberg's documentation for some easy to setup hosting. It should be easy to get Stat working for other hosting setups. Running deno task build builds the project for your custom domain but in the root of your repository. It is expected that built HTML output would be committed to the repo since that is how Codeberg expects it.
When updates are pushed to Stat, you can run git pull from within Stat. And when updated deno task update /path/to/existing/project and Stat will update the _stat directory for that project.
