Re: [racket-dev] lib changes between versions
I usually use this macro in a wrapper that require/provides the libs and provides compatibility wrappers when needed ;; compile time version switch (define-syntax (version>=? stx) (syntax-case stx () [(_ min-version body body-else) (if (string>=? (version) (syntax-e #'min-version)) #'body #'body-else)])) On Thu, 08 Jan 2015 02:56:16 +0100, Dan Liebgold wrote: Actually this issue is still perplexing me.

Re: [racket-dev] lib changes between versions
If your library's name is also `json` you could put in a place that is included in PLTCOLLECTS when you run v5.2.1, but use a PLTCOLLECTS that doesn't include it when your run v6.1 (in much the same way that you use different PLTCOMPILEDROOTS settings for the different versions). If your library has a different name, you could similarly point PLTCOLLECTS at it for v.5.2.1, and use a different implementation --- accessed either via PLTCOLLECTS or by installing as a package --- that wraps the main-distribution one for v6.1.

Re: [racket-dev] lib changes between versions
Actually this issue is still perplexing me. In 5.2.1 I have my own json lib which provides jsexpr->string. In 6.1 it's part of the distribution's collects directory.

[racket-dev] lib changes between versions
I'm maintaining the same racket code between Racket version 5.2.1 and 6.1. One thing that changed between those version was the json to string (and vice versa) lib functions. Is there a straightforward way to define those functions so they'll work with both lib versions?
