When using a reader conditional, ClojureCL selects the entry with the clj platform key instead of the clr platform key. The issue is on line 142 of the ListReader.cs file. It looks like the platform key code was copied over from the Clojure project without modifying the value for the CLR.
There is also a small, related issue with the changes.md file for version 1.7. The platform keyword is listed as 'cljr' in the changes.md file, but the reader documentation on clojure.org state that the platform key for the CLR is simply 'clr'.
ClojureCLR 1.7 on both Mono on OSX and .NET on Windows 7
I've attached two patches. One that fixes the issue in the ListReader.cs and one that updates the reader tests.
I've signed the CA. Apologies for not doing so before creating this ticket.
It looks like it should be :cljr after all. Here's an updated patch.
I applied the patch, built ClojureCLR, and ran my code on the patched version. After updating my code to use :cljr, the reader conditionals are now working as expected in my code. It looks like the reader conditional documentation on the Clojure site has also been updated with the correct key for the CLR platform. Everything now appears to be correct.
Patch applied in commits f3bc3f8, fb7f091 and bf36b98, 2016.01.03.
