Compiler patch to deprecate slist
> Deprecate slist

> Labels: slist

> I propose the slist type be deprecated (flagged by the compiler as scheduled
> for removal) in v1.0 and subsequently removed in a later version of Apache
> Thrift.
> Rationale: The Apache Thrift IDL type system is compact and elegant with few
> exceptions. The slist type is a string in all but PHP/Perl REST targets,
> where a string array is generated by splitting the input string on ‘,’. The
> slist type offers no cross language utility and is easily replaced in the two
> target environments which may require it. This type, and potential type
> additions like it, impact a wide range of concerns including language
> generators and the effort required to learn Apache Thrift.
> The only reference I can find to slist other than the Apache Thrift IDL
> syntax page is:

> [Mayan] What are slist & binary used for?
> [Mark Slee] slist is a silly meta-type that's used for the generation of a
> REST-style PHP server. It means the data type is a string of comma-separated
> primitive values. The generated handler will break apart the string by
> exploding on commas before passing to the application.
> This is the type of thing that ought to have been an annotation, not a
> special type. If we'd had the generic annotation system around at the time
> this was written, would have certain used it, but it was a bit of a
> quick-hack if I remember correctly.
> I'd support deprecating/fixing it now, since having it available as a type
> just causes confusion.

> If there is consensus I would be happy to attach a compiler patch producing a
> deprecation warning for slist (leaving it otherwise intact).
> Best regards,
> Randy
