I am trying to use jedit with the Isabelle development version

I have scala-2.9.1-1 and I downloaded jedit_build-20120313.

I set the paths

export SCALA_HOME=/Users/viorel/Work/isabelle-dev/isabelle/contrib/scala-2.9.1-1 export ISABELLE_JEDIT_BUILD_HOME=/Users/viorel/Work/isabelle-dev/isabelle/contrib/jedit_build-20120313

The file src/Tools/jEdit/README_BUILD says  to set ISABELLE_JEDIT_BUILD_HOME
via "init_component .../jedit_build...", but I don't know how to do it.

Isabelle settings are configured via etc/settings, either directly e.g. in your ~/.isabelle/etc/settings (for repository versions) or by initializing some Isabelle component. The Isabelle System manual explains the general principles behind etc/settings and etc/components.

The jedit_build-20120313 directory is already such a component, so if you say init_component .../jedit_build-20120313 in your settings it should work.


There is some chance though that in more recent latest versions of Isabelle, say 89b13238d7f2, you get another problem if JAVA_HOME does not point to a proper JDK installation -- say the one of the Isabelle2011-1/contrib in the Linux bundle. Here you need to set JAVA_HOME *outside* of the Isabelle environment or ISABELLE_JDK_HOME *inside* as settings.

I am in the course of refining that again soon ...
