Offline Export / Import

[exaptations]

I've been using JBang for a while and its handled everything I could throw at it.

I have a machine that is offline, and I was wondering if there is an easy and simple way to export just the the correct bits as a bundle, and import the bundle into the correct places. Ideally from the CLI

Best Regards

There is a jbang export command, is that what you're looking for?

It has the following export formats:

• portable -- Exports jar together with dependencies in way that makes it portable
• local -- Exports jar with classpath referring to local machine dependent locations
• mavenrepo -- Exports directory that can be used to publish as a maven repository
• native -- Exports native executable
• fatjar -- Exports an executable jar with all necessary dependencies included inside
• jlink -- Exports a minimized JDK distribution
• gradle -- Exports a Gradle project
• maven -- Exports a Maven project

In your case both "portable" and "fatjar" would probably be good options. The "fatjar" is probably easier to distribute because it's just a single file, but it's an experimental feature and might not always work. The "portable" creates a jar and a lib/ directory with all the dependencies (if any). You can zip both of them up and distribute.

Indeed that sounds like a good match.

I'll have a play and see how it works, given there is no import I'm assuming the Zip will be totally portable.

Thanks Tako.

had a quick play, so back for more knowledge :-)

My exact export need is to export an installed app in a manner that is portable.

Is this possible?

[maxandersen]

Wdym export an installed app?

Got example?

[quintesse]

Well that depends, do you mean that before you did something like jbang app install myapp.java (or jbang app install myapp@example) and that you want to copy that to some system that doesn't have internet?

It could still work, if you:

1. do the export, copy the zip/jar to the other machine
2. jbang app install myapp.jar

The issue here is that you'd need to manually install JBang and Java, so it wouldn't be completely trivial.

Let us know what you're trying to do exactly so we can give more detailed advise.

[exaptations]

I'll try to be precise.

I love JBang its awesome. So awesome that I want to use in in place that I don't have the internet, but where the is a JDK.

1st use case is to bundle up some apps and JBang, and unzip and go.

Because everything in JBang is declarative and uses a strong convention if I have to do this manually in some bash that pulls stuff into a zip then I'm cool with that.

I could well be crazy to even think of such a use case maybe ;-)

Tried jbang wrapper ?

If you have a script you can run jabng wrapper install can get a ./jbang that will run.

Maybe https://github.com/jbangdev/jpaxa is what you are after ?

[exaptations]

Indeed.

Jpaxa seems ideal.

Thanks for the J'banging support :-)
