cli-matic.platform
Platform-specific functions for the JVM.
If running on ClojureScript, we can have a different file for JS.
BTW, in this NS, we avoid using Spec / Orchestra.
DO NOT define macros in this namespace - see cli-matic.platform-macros

At the moment, we only support Planck.

add-shutdown-hookclj/s≠
(add-shutdown-hook fnToCallOnShutdown)Add a shutdown hook. If nil, simply ignores it.
The shutdown hook is run in a new thread.
Add a shutdown hook. If `nil`, simply ignores it. The shutdown hook is run in a new thread.
Add a shutdown hook.
Does not work (?) on CLJS and we will throw an exception.
It might be conceivable that in JS-land, we save this locally in this namespace
and then call it on exit-script.

asDateclj/s
(asDate s)Converts a string in format yyyy-mm-dd to a Date object; if conversion fails, returns nil.
Converts a string in format yyyy-mm-dd to a Date object; if conversion fails, returns nil.
exit-scriptclj/s≠
(exit-script retval)Terminates execution with a return value.
Terminates execution with a return value.
Terminates execution with a return value.
Please note that in Planck, return codes seem to be 8-bit unsigned ints.

isDeferredValue?clj/s≠
(isDeferredValue? v)(isDeferredValue? _)Is this a deferred value for this platform?
Is this a deferred value for this platform?
parseEdnclj/s≠
(parseEdn edn-in)Decodes EDN through clojure.edn.
Decodes EDN through clojure.edn.
This is actually a piece of ClojureScript, though it lives in a different NS.

parseFloatclj/s
(parseFloat s)Converts a string to a float.
Converts a string to a float.
parseIntclj/s
(parseInt s)Converts a string to an integer.
Converts a string to an integer.
printErrorclj/s≠
(printError o)On ClojureScript, STDERR is not err but it's platform dependent. On JVM, standard approach.
On ClojureScript, STDERR is not *err* but it's platform dependent. On JVM, standard approach.
On ClojureScript, STDERR is not err but it's platform dependent.

read-envclj/s
(read-env var)Reads an environment variable. If undefined, returns nil.
Reads an environment variable. If undefined, returns nil.
slurp-fileclj/s≠
(slurp-file f)No slurping in JavaScript. So we have to move this to platform.

Luckily, Planck implements slurp for us.
No slurping in Node-land.

waitForDeferredValueclj/s≠
(waitForDeferredValue v)Given that value is a deferred value for this platform, block termination until it's realized.
On the JVM, we support:
- promises
- futures
- core.async channels (if they exist)

On JS, we support:
- nothing yet...
