feat: Added support for script dependencies

[quintesse]

You can now do:

//DEPS local_file.java http://www.example.com/remote_file.java

And those files will be compiled, if needed, and added as dependencies on the classpath.

Awesome. Does swizzled urls work too? Ie. For gist and fully qualified catalogs?

[maxandersen]

Why are these patterns changing?

[quintesse]

Because they are too lenient, they match URLs that are not valid JitPack URLs

[quintesse]

For example it will match https://github.com/jbangdev/jbang/blob/main/itests/SankeyPlotTest.java , even though that's obviously neither a "tree" nor a "commit".

Haven't tried yet, this is the first working version 😉

Edit: I don't think aliases will work, though...

first quick test with this beauty:

///usr/bin/env jbang "$0" "$@" ; exit $?
//DEPS info.picocli:picocli:4.6.3
//DEPS https://github.com/jbangdev/jbang-catalog/blob/main/httpd.java


import picocli.CommandLine;
import picocli.CommandLine.Command;
import picocli.CommandLine.Parameters;

import java.util.concurrent.Callable;

@Command(name = "hello", mixinStandardHelpOptions = true, version = "hello 0.1",
        description = "hello made with jbang")
class hello implements Callable<Integer> {

    @Parameters(index = "0", description = "The greeting to print", defaultValue = "World!")
    private String greeting;

    public static void main(String... args) {
        int exitCode = new CommandLine(new hello()).execute(args);
        System.exit(exitCode);
    }

    @Override
    public Integer call() throws Exception { // your business logic goes here...
        System.out.println("Hello again " + greeting);

        httpd.main(new String[] { "--port=8080" });
        return 0;
    }
}

at first glance worked - even vscode picked up the new deps.

a few things:

[jbang] Building jar...
[jbang] Resolving dependencies...
[jbang]    info.picocli:picocli:4.6.3
[jbang] Dependencies resolved
[jbang] Building jar...

The Building jar should have some indication of what its building now.

If touch just the hello.java I still get:

jbang hello.java
[jbang] Building jar...
[jbang] Building jar...
Hello again World!

shouldn't there only be one Building Jar in that case ?

[maxandersen]

//JAVA 21+
//PREVIEW
//DEPS hello.java

void main() {
    System.out.println("Hello, world!");
}

instant stack overflow :)

[maxandersen]

btw. //DEPS other.jar works. sweet!

[maxandersen]

//DEPS httpd@jbangdev does not work...part of me says it shouldn't but then again....its pretty damn nice if it could work.
