Thanks Rob for your comments.
The main issue is there are not enough developers to get it back up to
snuff--only maintain what we have. JDEE is very large and IMO it needs to be
reduced to eliminate bloat and then expand through a more flexible plugin
framework.
It's been my plan for many years to fork it implementing some design changes
but this is a lot of work all at one time for one person. It is even more work
to keep use a new fork code base and continue developing Java with JDEE, which
is what I currently do.
Most of the original authors of JDEE don't write Java anymore, but if there is
enough interest a new fork and I had others to help out I'd think more
seriously about embarking on such a project in the shorter term.
Basic technology stack I was thinking:
- Maven :all builds, dependencies, project related stuff resides in a pom
(regardless of if you choose to use maven as a build tool).
- Clojure: I've been using Clojure now for the last year or so and have decided
for very practical reasons to use it instead of a CommonLisp based JVM language
(i.e. Armed Bear/ABCL)
- Leiningen (http://leiningen.org): mostly for the Clojure Java integration
side stuff but there might be something useful on the project setup side as
well.
- Cider: I'm currently using nrepl, but I hear this is the new direction for
Clojure/Emacs integration.
- Move semantic functionality to some JVM based API. Upside is this gets rid
of some limitations and complexity of semantic, but increases complexity on the
JVM side.
- Investigate some of the Eclipse libraries (not IDE) to see if there could be
some reuse. That said, I'm reluctant to do too much with this as a lot of
their work involves dumping a JVM and reloading because of the way class
loading works.
- Move to Github
Regarding the Eclipse libraries: Ideally there would be no class loading at all
and we could use some library (written in Java or any other language) to do
everything Beanshell currently does. The code generation would be straight
forward, but the reflection would be hard since it currently uses ASM to
compile and then class load what you've written. However, Eclipse is able to
grok your code and do things like method completion before it successfully
compiles it. I have to believe they have some library (or use a third party
library) to do this and it doesn't involve class loading.
I started to investigate dynamic class reloading in Clojure and I've found the
facility does indeed exist, but is less accessible. I started to look at a
library on git that makes class loading straight forward, but it appears this
library is no longer compat with newer versions of Clojure.
If there are any volunteers, i.e. someone more familiar with the Eclipse code
base, maybe someone can look into what libraries would work.
In the past, discussion like this has lead to more discussion but no action.
Maybe something will change.
