What methods and tools are there for i18n of Haskell programs? (I.e. I want output in several languages, with the language configurable at runtime, and I want to add languages without recompilation.)
a typical source text (for my application) is here http://141.57.11.163/cgi-bin/cvsweb/tool/src/Graph/Circle/Plain.hs?rev=1.2 it contains (German) text strings all over the place. In Java/Eclipse, I would "Source -> Externalize Strings" and this replaces each string by something like Messages.getString("Foobar.0") where Messages is a global variable (constructed at program start from reading a properties file) In Haskell, I see at least two problems: a) reading the file is in IO b) there are no "global variables". implicit parameters perhaps? c) when I'm trying to be clever, I use "deriving Show/Read" or similar. then i18n should rename the constructors/accessors? I rather not. http://141.57.11.163/cgi-bin/cvsweb/tool/src/Grammatik/Type.hs.drift?rev=1.6 Best regards, -- -- Johannes Waldmann -- Tel/Fax (0341) 3076 6479/80 -- ---- http://www.imn.htwk-leipzig.de/~waldmann/ ------- _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
