Convert to Java system properties

[ulsa]

Sometimes I need to convert keywords and environment variables to/from the Java system properties syntax that environ uses, eg:

:database-url -> DATABASE_URL -> database.url

Would be nice if this library had that option.

[ulsa]

Workaround:

(defn ->java-system-properties-string [k]
  (clojure.string/replace (snake/->snake_case_string k) \_ \.))

[qerub]

Would be nice if this library had that option.

Agreed.

(defn ->java-system-properties-string [k] …)

I'd prefer the name ->java.system.property.string (with ->java.system.property as the base version) to make the name mirror the output.

Is there perhaps an even better name that doesn't involve Java?

[ulsa]

Actually, I tried a name with dots first, but the compiler interprets that name as a Java class. Maybe just a name involving "dots", like dotted-lowercase-string or something?

I'm actually not that happy about names with various delimiters in them. Even though Clojure is forgiving about characters in symbols, there will be clashes (as the Java thing above illustrates). I prefer dashed but descriptive names.

[qerub]

How do you feel about the identifiers that for illustrative purposes have mixed case (e.g. camelCase and HTTP-Header-Case)?

[ulsa]

I admit that they illustrate their purpose, but I think that naming style hurts my ability to make intelligent guesses about names in the library, and that forces me to look them up every time. In the end, I would prefer that they all followed the Clojure naming standard. But that's just me.
