When/how should we update Frog?

[gasche]

greghendershott/frog#180 was just merged upstream, which fixes a bug that affects our blog (it makes it painful to read for (at least) Thunderbird users that subscribed to the RSS feed.) How can I make sure that the version of frog used to generate the blog contains the fix?

You can check by:

• uninstalling frog on your machine (raco pkg remove frog)
• re-installing frog (raco pkg install frog)
• rebuilding the blog

If it looks good,* then it should look good on the website. Because building the website:

• uses a travis script
• which installs Racket v6.6
• and then runs the website/blog's Makefiles;
• the blog's Makefile runs raco pkg install frog
• which gets the "most recent available frog"

Racket's basically "rolling release" for all packages. You can make a version exception (users of Racket v6.6 get the v6.6 of package "My-Pkg"), but frog isn't doing that so the website should be getting the most up-to-date.

(* If it doesn't look good, maybe wait a few hours for the Racket package server to update its copy of frog)
