Every commit to main gets built and deployed using build.yml. R package builds are cached on GitHub and deployment currently takes ~7 minutes until the website is live.
If additional R packages are required add them to r-packages.nix replacing all . in packages names with _ (i.e., data.table would be data_table). All packages on CRAN and BioConductor are available by default. If a package needs to be installed from GitHub see FRAN and possibly add it as an input to flake.nix which defines the build system. An example standalone addition would be:
(prev.rPackages.buildRPackage {
name = "synthdid";
src = prev.fetchFromGitHub {
owner = "synth-inference";
repo = "synthdid";
rev = "70c1ce3eac58e28c30b67435ca377bb48baa9b8a";
sha256 = "sha256-rxQqnpKWy4d9ZykRxfILu1lyT6Z3x++gFdC3sbm++pk=";
};
propagatedBuildInputs = [prev.rPackages.mvtnorm]; # see Imports in DESCRIPTION file
};)where rev is the commit reference and sha256 is the hash of the repository at that commit. Leaving sha256 empty will generate an error displaying the correct hash (also see nix-prefetch-github). The propagatedBuildInputs correspond to the Imports in the DESCRIPTION file of a package.
On the 1st of September every year automated pull requests are triggered:
- R gets updated using update.yml
- Learning checks are removed using remove_learnchecks.yml
These can also be triggered manually under "Actions":
Changes to the the website or build system can be tested on the testing branch. CI will check if the website still builds after the change after which it is safe to merge into main.
