Since version 0.4.1, JTransc supports a plugin system using the plain Java’s ServiceLoader.
You must add to your JAR this file:
META-INF.services/com.jtransc.plugin.JTranscPlugin
With the fqname of your implementation. That class should extend the abstract class com.jtransc.plugin.JTranscPlugin.
You can see some examples of plugins to discover the API at that moment:
jtransc-core/src/com/jtrans/plugin/jna/JnaJTranscPlugin.ktjtransc-core/src/com/jtrans/plugin/meta/MetaReflectionJTranscPlugin.ktjtransc-core/src/com/jtrans/plugin/service/ServiceLoaderJTranscPlugin.ktThe plugin system allows to reference classes/methods/fields, to modify the program (adding classes, methods, fields or modifying them) before or after the ThreeShaking phase.
