v0.93.0

Changelog

Mainly small fixes.

JBang no longer uses @file for large classpath/command lines with JShell. This should allow it run for more things; but can also give problems with large dependency sets on Windows. Recommend to use powershell or a linux-like terminal on Windows to avoid problems.

Export now is possible for projects without a main, i.e. for building libraries.

Also //FILES will now tell you what file pattern failed to be resolved. Making it easier to debug.

v0.92.0

Changelog

This time with a mixed bag of features/improvements:

Console trust and "zero" install

Running using curl will now download jbang to a temporary location if no local .jbang jar found. This ensures if you run curl install it will use the latest available.

Also When installing or running jbang using curl osx and linux will now use /dev/tty to
allow using console to approve/trust scripts. Windows will still use the UI based approach if necessary.

We also now don't ask to trust a script you already downloaded and not running with --fresh.

This should all make the installation of jbang and running of scripts simpler and more reliable.

Integrations can run externally

Today when using jbang integrations (i.q. Quarkus integration) it runs in the same jvm/classloader
as jbang itself. This works normally great, but if you are targeting a Java higher than the Java you are running JBang with (i.e. uses --java 17 when running with Java 11) you can get errors about mismatched Java versions.

In this release JBang now will run the integration in an external process when Java versions does not match.

This also enables a future possible improvement of making jbang a native binary.

Allow aliases for //SOURCES

You can now use aliases in //SOURCES. This is mainly interesting when running jshell based scripts. For example in a .jsh file you can use //SOURCES faker@jbangdev and you get the faker script included.

Enjoy!

v0.91.0

Changelog

Buckle up - this is a fun release enabling some long-awaited mythical features!

  • Aliases for sources: cat logs.txt | jbang -s prelude@maxandersen -c '$$(l -> l.s(2))'
  • Websites as implicit catalog jbang [email protected]
  • Custom JDK Install: j! jdk install 18 $(sdk home java 18-open)

Details below:

Use of aliases for sources

You can now use an alias to load additional sources, i.e. jbang -s myscript@mycatalog ... - all thanks to @quintesse super refactoring!.

At first, that might not look that interesting but combining it with the previous release where we added support
for running snippets with jbang -c you can now load in a custom source that fetches dependencies and add
use case-specific top-level methods and classes.

As an example I'll use Edoardo Vacchi's idea about implementing AWK in JBang using a script called Prelude.jsh.

Imagine you have a logs.txt with the following content:

GET /robots.txt HTTP/1.1
HEAD /README.md HTTP/1.1
GET /wp-admin/ HTTP/1.0

And you want to print out all the paths in that log.

There is a ton of ways to do that but if you use raw java it might be quite verbose.

Now with aliases we can cut this down to:

cat logs.txt | jbang -s prelude@evacchi -c '$$(l -> l.s(2))'

This will load the script behind prelude@evacchi which provides a method named $$
which iterates all input and give you a Line instance where there are various methods to extract
content, i.e. l.s(2) gives you the second column.

You can load multiple scripts from anywhere making it possible for everyone to make
interesting toplevel methods available to do useful things like the AWK example above; or maybe
just to make it fun/easier to try out your framework/api.

Looking forward to see what crazy ways you find to use this.

Websites as implicit catalog

Until now jbang's implicit catalogs allow you to have a jbang-catalog repository, i.e. @maxandersen was shorthand for catalog found in https://github.com/maxandersen/jbang-catalog. Very useful to have short and recognizable names.

Thus now if there is a '.' in the name jbang will lookup a website with that name first.

For example: jbang [email protected] will use the catalog available at https://xam.dk/jbang-catalog.json.

There are more ways this can be used and expanded - those are covered in the docs.

Install of custom JDK's

We've had many requests on having jbang utilize existing Java installs on your machine rather
than download Java separately. i.e. use sdkman's jdk installs.

We don't do that for various reasons (mainly portability), but with @nandorholozsnyak's great contribution you
can now install custom JDK's using: jbang jdk install <version> <pathtojdk>.

Example:

Lets say you use sdkman and you want to try out Java 18 with JBang - something that today will fail
unless you have Java 18 installed as default jdk.

You can then run:

j! jdk install 18 `sdk home java 18-open`

which setup the path printed by sdk home java 18-open to be what what JBang treat as Java 18.

Then you can run:

j! --java 18 -c 'println(javax.lang.model.SourceVersion.RELEASE_18)'

v0.90.2

Changelog

Critical fix to avoid untrusted code to run and not auto-install vscode.

Plus if you have a M1 based machine jbang will no longer fail on first run.
jbang will now download Java 17 by default as Java 11 is not yet available from Adoptium.

Changelog

Small changes this time with a big impact.

-i for interactive without sources

You always could to jbang --interactive <your.java|jsh|jar|gav> to have jbang start up your application/script within the jshell interpreter. Which is great but what if you just wanted to try out some API's without having to bother making a file to get started?

Now you can - just use jbang --interactive or jbang -i for short and you have a jshell. Of course that in itself is not interesting, but when you combine it with --deps it does become interesting. i.e. below is an example of starting jbang in interactive mode with access to h2 and jandex libraries.

jbang --deps com.h2database:h2:LATEST,org.jboss:jandex:2.4.2.Final -i
WARNING: Using incubator modules: jdk.incubator.vector, jdk.incubator.foreign
|  Welcome to JShell -- Version 17
|  For an introduction type: /help intro

jshell> import org.jboss.jandex.*;

jshell> Index.of(org.h2.Driver.class);
$2 ==> org.jboss.jandex.Index@9f48198

-c for code snippet execution

jbang now can execute java code directly allowing you to process standard input to make great one-liners like:

$ echo "hello world" | jbang -c 'lines().forEach(s->println(s.substring(6)))`
world

or this check for how many 5 letter words contains Man's best friend?

$ cat 5letterwords.txt | jbang -c 'lines().filter(s->s.contains("dog")).forEach(p->println(p))'
WARNING: Using incubator modules: jdk.incubator.foreign, jdk.incubator.vector
bedog
dogal
dogey
doges
doggy
doggo
dogie
dogly
dogma
dogra
undog

In the last example you will notice a few things:

  1. -c enables that the first argument is treated as code instead of a script
  2. a top-level method called 'lines()' is available to read lines from System.in
  3. println top-level method is available to easily print.

We got more ideas on adding some top-level methods to enable using java on
the command line.

And of course you can combine -c with --interactive and --deps and even
-s myscripts.jsh to load your own top-level methods.

Enjoy and Stay tuned :)

v0.89.1

Changelog

0.89 fixes long-standing issue in how jshell was setup with dependencies. Turns out that to have execution AND content-assist working you must specify the classpath twice. Quite bad UX when using 3rd party dependencies but now jbang have it fully working :)

Imagine you have a file named deps.jsh that uses the Faker library:

///usr/bin/env jbang "$0" "$@" ; exit $?
//DEPS https://github.com/blocoio/faker/tree/1.2.8

import io.bloco.faker.Faker;

Faker fake = new Faker("da-DK");

Then you can run it directly using ./deps.jsh or jbang deps.jsh but you can also use jbang --interactive deps.jsh to have some fun with Faker.

2022-02-12_00-42-26.mp4

Compare that to what you would need to write out using raw jshell:

jshell --execution=local -J--add-modules=ALL-SYSTEM --class-path=/Users/max/.m2/repository/com/github/blocoio/faker/1.2.8/faker-1.2.8.jar:/Users/max/.m2/repository/com/github/bmoliveira/snake-yaml/v1.18-android/snake-yaml-v1.18-android.jar:/Users/max/.m2/repository/joda-time/joda-time/2.9.1/joda-time-2.9.1.jar -J--class-path=/Users/max/.m2/repository/com/github/blocoio/faker/1.2.8/faker-1.2.8.jar:/Users/max/.m2/repository/com/github/bmoliveira/snake-yaml/v1.18-android/snake-yaml-v1.18-android.jar:/Users/max/.m2/repository/joda-time/joda-time/2.9.1/joda-time-2.9.1.jar --startup=DEFAULT --startup=/var/folders/yb/sytszfld4sg8vwr1h0w20jlw0000gn/T/jbang_arguments_12529495078878297375deps.jsh /Users/max/code/personal/jbangdev/jbang/itests/deps.jsh

Simplicity FTW :)

Also include fix (#1232) so jbang init actually will honor default properties for a template.

Thanks to @nandorholozsnyak and @quintesse!

v0.88.0

Changelog

New JBang release with a bunch of quality of life improvements.

Graphical UI when needed to confirm trust

To simplify install/setup running in a environment where there is no terminal to ask for input, i.e. if using curl for install
we now show a graphical dialog when needing to confirm trusted URLs or choosing an editor. This was not
an easy decision but it enables to have just one command install, like: curl -Ls https://sh.jbang.dev | bash -s - app install quarkus@quarkusio

2022-02-04_00-56-32

Note: this will only show up if needed and AWT/Swing is available, if not the text based info is used instead.

Edit knowing about common editors

When using jbang edit by default we offered to install and run vscodium - now we also scan PATH for common IDE's like eclipse, code, idea` etc. Giving you a choice to use your already installed IDE more easily.

2022-02-04_01-01-39

Setting JDK Release

JBang uses foojay.io to download Java Development Kit's normally getting Adoptium major releases.
If you want to try out another distribution and even earlyaccess versions you can now tweak these using environment variables

JBANG_JDK_VENDOR vendor name, ie. `temurin`, `aoj`, `azul`, `debian`, `microsoft`, `openjdk`, `oracle`, `oracle_open_jdk` or `redhat`
JBANG_JDK_RELEASE `ga` or `ea`

You can set these in your environment or use them directly when calling jbang, i.e.:

JBANG_JDK_VENDOR=oracle JBANG_JDK_RELEASE=ea jbang --java 18 otp.java

This will get latest Java 18 early access release of Oracle JDK.

//SOURCES now supported in .jsh

When using .jsh (jshell) //SOURCES are now supported allowing you to include
other .jsh files.

Catalog can now document its properties

@nandorholozsnyak in his first contribution enabled Catalogs to document its properties
and will be included in jbang catalog list.
