Terry Pratchett died the 03/12/2015. As a tribute, I had published a small application which generate a ook program, in order to sent him a message.
This is the oldest code I’ve keeped both the source and the compiled version (with js_of_ocaml) and the js binary starts with this header :
// Generated by js_of_ocaml 2.5
Does it still compile today ? No. At this date, js_of_ocaml relied on camlp4, and a syntax change into the ppx world broke the code. This is however easy to fix :
diff library.ml library_402.ml 1d0 < open Js_of_ocaml 11c10 < global##.converter := --- > global##converter<-
With this little change, I compiled my code with the latest ocaml and js_of_ocaml code. Surprisingly the binary size grew up, from 12k to 75k!
I have created a gist with the code and the results with differents versions. I’m interrested if you have any feedback.This does not seems related to OCaml compiler itself, but with js_of_ocaml (between v3.0 and v3.5): did I miss a compile flag? Is there any other feedback from maintaining the same code over years and comparing the results ?
