What I was using was a gettext/printf template haskell function that can be hunted for with xgettext, which expands to code that reads translated .po files for the current module at two different times. Once at compile time to check that any printf-style format strings are compatible across each translation, and again later at runtime to allow for additional translations to be added. The biggest headache I have is that doing all this requires a pretty hairy .cabal file, and I haven't yet figured out how to package that up nicely for use in libraries. I'll admit I have only ever really tested this with a joke en@lolcattranslation, which I auto-translate with perl, though I admit if I could find a nice perl module for generating zalgo-style text, en@zalgo would be pretty neat to auto-generate as well. I'm not sure its considered "best practice", since I haven't bundled it up for third party use yet, but its *my* practice. ;) -Edward Kmett > This is what I've been looking at lately.
