[elm-discuss] Encoding JSON and updating

I am using a simple JSON decode and encode (following from examples at elm-tutorial ), but I'm clearly missing something. The *db.json* file has the simple structure { "plrs": { "ixd": "FF", "name": "Frank", "level": 3 } } .. and I decode that

Does Elm have anything between an *if-then-else* flow control and* case* ? My use case is, I need to parse a string in various ways to decide which Analysis ADT to assign to the string. Thus sconvert : String -> Analysis sconvert s = if s=="all" then AllDays else if s=="unplayed"

I have been porting a language translation engine from HTML/JS to Elm, and it was easy to implement. The problem is that the dictionary contains 15,000 word pairs. I can't include those items as Elm files (since Elm-make runs out of memory), so I decided to put them in a JSON file and import
