drip Using drip for javac

I'd like to use Drip to run javac commands (basically for checking the syntax of a file whenever I save it in Vim). I'm pretty sure javac ... is just a wrapper around a java command so it should be possible to use Drip instead. Any idea how I might do that?

This should be possible. You'd need to figure out the equivalent command line for javac using java.

Yep, that's what I'm looking for but can't seem to find. It would be nice to have it in Drip's docs since a lot of people would probably find it useful.

The best I can find is that there's a programmatic interface for javac, so maybe write a small java program that takes the program to compile as an argument and uses the programmatic interface?

Apologies in advance if this is a dumb/obvious observation, but my javac is a binary, and since the JRE includes the java command but doesn't ship a compiler, it seems like javac has to be much more than a wrapper around java (unless the JDK ships a different java command than the JRE?). What am I missing here?

Although the modern way to do it is creating a java main class that use the javax.tools.JavaCompiler class it's still possible to use the deprecated sun.tools.javac.Main class:

java -classpath /usr/lib/jvm/default-java/lib/tools.jar sun.tools.javac.Main MyClass.java

@trptcolin I guess that the only reason why javac is not a script wrapper around java is that not all system offer decent builtin script capabilities.

I'd like to use Drip to run `javac` commands (basically for checking the syntax of a file whenever I save it in Vim). I'm pretty sure `javac ...` is just a wrapper around a `java` command so it should be possible to use Drip instead. Any idea how I might do that?
