The Yesod scaffolding, with branches for different versions.

If you want to send a pull request affecting all the different flavors, please send it as a pull request against the postgres branch. The scripts we use for building the scaffoldings automatically merge changes from postgres to all other branches.

If you have a patch which is backend-specific, please send a pull request to the appropriate branch, with a comment that this change applies only to the specific branch.

Build Process

The code contained by the scaffolding itself is all contained on separate branches. The master branch contains code for performing merges between these branches, testing that the branches build correctly, and generating the .hsfiles used by the stack-template repository. (Note: the full list of recognized branches is maintained in the app/Main.hs file on the master branch, in the branches value.

The basic workflow for this repository is as follows:

1. Changes are made to one of the branches. If the change is intended to be applied to all variants, it should be made to the postgres branch (as mentioned above).

2. Changes on a branch can be tested with normal Stack commands, e.g. stack test --haddock.

For maintainers

If you are a maintainer of this repo, you will additionally need to merge changes from postgres to other branches and deal with updating the stack-templates repo.

Install the yesod-scaffold executable by running stack install on the master branch.

Merge changes from postgres to all other branches by running yesod-scaffold merge. Note that there will often be merge conflicts, which will need to be resolved and then the command rerun until all branches merge successfully.

Confirm that changes build correctly by running yesod-scaffold build. Usually you'll want to add --no-run-tests if you don't have databases set up locally. The Travis builds set up the databases for proper testing, and you can rely on that. If you encounter a build error on one of the branches, check it out, fix it up, and then rerun yesod-scaffold build.

Copy the template files in the hsfiles directory. This directory is populated after a successful yesod-scaffold build run. Place the stack-templates directory as a sibling to the yesod-scaffold directory, and then run the to-stack-templates.sh script.
