This adds preview deployments that will deploy a version of egui_demo_app for each pull request, making things easier to review / test. Some notes on security: The preview deployment is split in two workflows, preview_build and preview_deploy. `preview_build` runs on pull_request, so it won't have any access to the repositories secrets, so it is safe to build / execute untrusted code. `preview_deploy` has access to the repositories secrets (so it can push to the pr preview repo) but won't run any untrusted code (it will just extract the build artifact and push it to the pages branch where it will automatically be deployed). To set this up, a DEPLOY_KEY secret needs to be added, which allows the action to push the compiled artifacts into this repository: https://github.com/egui-pr-preview/pr The deploy key is the private key part of a key generated via ssh-keygen. The public key is set as a deploy key in that repo. I have created the repo on a separate github org, so it won't be directly associated with emil or egui in case someone pushes something naughty. I have set this up in my fork of egui to show how this works: - I created a PR: https://github.com/lucasmerlin/egui/pull/2 - The code will be compiled and pushed to the egui-pr-preview/pr repo and deployed via github pages - The bot leaves a comment on the pr with a link to the preview - The preview is available at https://egui-pr-preview.github.io/pr/2-pr-preview-demo/ (It's unfortunately only available a couple seconds after the bot writes the comment, because the pages deployment action is run independently on the other repository) - Once the PR is merged / closed the preview will be cleaned up (unfortunately the empty folder will remain, it seems like it's not possible to remove that via the JamesIves/github-pages-deploy-action action I use, but I don't think that it's a big issue) I'll leave the PR in draft until the DEPLOY_KEY is set up
