setup-msys2 VS ghactionsbyexample

Other pages provide complementary information on that same topic.

Another thing I appreciated was the explanation of MSYS2's environments:

https://www.msys2.org/docs/environments/

Being able to painlessly switch away from MSVCRT to UCRT was helpful in solving some UTF-8 difficulties I was experiencing at the time.

Package management with pacman is rather pleasant, and the setup-msys2 GitHub Action makes it simple to provide your GHA workflow with the tools and libs you want:

https://www.msys2.org/docs/package-management/

https://packages.msys2.org/queue

> Actions reduce workflow steps by providing reusabe[sic] “code” for common tasks. To run an action, you include the uses keyword pointing to a GitHub repo with the pattern {owner}/{repo}@{ref} or {owner}/{repo}/{path}@{ref} if it’s in a subdirectory. A ref can be a branch, tag, or SHA.

Aside from the typo, I wonder how many packages could be backdoored at once, if an action maintainer went rogue, seeing as there's no pinning for actions by default, and (according to https://github.com/msys2/setup-msys2/blob/main/HACKING.md) moving a tag is the default way to push updates to an action. (Interestingly get-cmake/run-cmake/run-vcpkg are all operated by the same person.)

Thanks! The page itself is just simple HTML and tables. I generated it from YAML files with a custom HTML generator, see for example: https://github.com/macintoshpie/ghactionsbyexample/blob/df6f...
