Clojurians Log v2

https://github.com/jcburley/joker/releases/tag/gostd-v0.10  https://github.com/jcburley released this 2 minutes ago · https://github.com/jcburley/joker/compare/gostd-v0.10...gostd to gostd since this release All (exported) constants are now wrapped; evaluation of constant expressions is now done via `go/types`, `go/importer`, and `go/constant`, rather than via custom code in `gostd`. Constant types are now preserved. E.g. `http://go.std.net/FlagUp` is of type `net.Flags`, not `Number`, so this now works (as `http://go.std.net/Flags` is the type for `FlagUp` and defines a `String()` method for it and other constants), instead of just `1N` being printed:

@roman.bataev: if you find some time, please review the changes to how BigFloats are handled, and let me know what you think and whether you want me to do up a crossport PR for official Joker. Specifically: MakeBigFloat* are new APIs, and the WithOrig() one is now used by read.go for arbitrary-precision constants (ending in M); instead of setting precision to a constant 256, they compute the precision based on the number and “width” of digits in the constant (minimum being 53, the precision for a float64 aka Double); and a new core function precision returns the precision info (and I’m happy to create a set-precision that’d work on BigFloat if there’s any interest).

Hey @james-clojure , can you post this as a github issue? On vacation right now, not sure when I’ll get to looking into this.

What a coincidence: we’re on vacation too this week (in Avon, CO)! Between weather and other stuff, I’m finding plenty of “down time” to just hack away on Joker, as often happens on vacation…. Enjoy!

You too!
