Trivial for-each sugar

A snippet of for-each syntatic sugar for Java loops:

for (final Person person : each (ALICE, BOB, CAT))
    person.say("Hello!");

And elsewhere:

public static <T> T[] each(final T... array) {
    return array;
}

Java code beautifier

Where are the Java code beautifiers? My criteria:

1. Formats in standard SUN Java style
2. Works on JDK5+ Java code
3. No licensing required—free as in beer

Not very many criteria! And yet … very little turned up that did not violate one requirement or the other. I came up with exactly one match: Jacobe, personal edition.

More generics hackery: utility method for pulling out types

Andrew Phillips posts A general-purpose utility to retrieve Java generic type values which fits in nicely with Gafter's Gadget and TypeLiteral from Guice.

Two miracle utilities: rlwrap and screen

Two miracle utilities: rlwrap and screen.

rlwrap

Ever wish you had nice command-line editing like BASH but the tool you are using is hopeless? rlwrap is the tool for the job: it is a readline wrapper for any program that reads from stdin. A classic use case is wrapping sqlplus.

screen

Say you have an on-again, off-again shell session you come back to throughout the day. You could keep a shell window open all day. But what if you change machines, say from a laptop to a desktop and back again? screen is the tool for the job: it is a full-screen window manager for terminal sessions. Disconnect from the current session, keep screen running in the background, and reconnect later at your convience. Nothing is lost.
