ys::io - The YS Stream I/O Library

The ys::io library reads from open input handles and writes to the standard output streams. It does not expose clojure.java.io or open filesystem paths.

Stream Input

• readline(Reader) → Str? — Read one line, returning nil at end of input

Stream Output

• err(Str*) → nil — Print to stderr without a newline
• out(Str*) → nil — Print to stdout without a newline
• print(Str*) → nil — Print to stdout without a newline
• say(Str*) → nil — Print to stdout with a newline
• warn(Str*) → nil — Print to stderr with a newline

The standard readline() proxy reads from IN. Pass an explicit input handle as IN:readline or fh:readline.
