Project bashj : a bash mutant with java support
What ?
The bashJ & java Shell Bridge project is hosted on sourceForge.
bashJ is an extended bash allowing to use java libraries and java code in scripts.
Java Shell Bridge is the underlying technology used by bashJ. It is mainly a server excuting java code for the benefit of a bash session (interactive or scripted).
Why ?
Java and bash are often partners in software projects.
Their possible interactions are numerous but limited in terms of integration.
With this project, any script is given the capacity to quicly and directly call java methods without creating new OS processes.
Limitations &
- bash only
- Linux only
- java 9+
- public static methods only
- methods with primitive types (including String) as parameters and return value
- no varargs
