You can edit your script in an IDE/editor by using
jbang edit helloworld.java. This will generate a project in a temporary location with symbolic links to your script
and output the generated folder name. The easiest way to use that is to use it in a call to your IDE:
code `jbang edit helloworld.java`
If you add further dependencies to your file just re-run the edit command and the relevant files will be regenerated with the updated dependencies.
Above does require using a shell that allows for variable evaluation, if you are on i.e. Windows then you might prefer using:
jbang edit --open=[editor] helloworld.java
The editor used will be what is specified as the argument to
--open or value of
JBANG_EDITOR environment variable.
The editor command must be available on the PATH to be executed from jbang. If you are executing
jbang edit --open=code helloworld.java a
code executable (visual studio code) must be on the PATH. Next to this you can pass the full path to the
open parameter like in
On Windows you might need elevated privileges to create symbolic links. If you don’t have permissions then
If no editor available at all jbang will offer to install VSCodium (free/libre version of Visual Studio code) with
default java extensions enabled in so called "portable mode". Portable mode means all
the installed binaries and configuration does not affect rest of your system; everything is stored in
This automatic install and setup of editor is fully optional and if you have another IDE or editor already installed
use it using
jbang edit --open=<editor> or set JBANG_EDITOR environment variable to have jbang use it by default.
You can also use
jbang edit --live and
jbang will launch your editor while watching
for file changes and regenerate the temporary project to pick up changes in dependencies.
edit feature been tested with the following IDE’s:
edit feature works with various IDE’s - it generates a
build.gradle to use with IDE’s that understands Gradle directly.
For speed and consistency
jbang also generates IDE specific settings.
Currently launchers and project files are generated for Eclipse and vscode. Intellij just reads
build.gradle for now thus
to run/debug you will need to manually set it up.
Some editors like Code or IDEA are not per default executable / startable from the command line. Here are some helpfull documentations for supporting command line usage of different editors:
