OSX code completion for jruby/ruby not complete [message #956700]

I'd like to use DLTK to develop some ruby and jruby scripts.
This works good in most cases.

Unfortunately code completion is not complete for default-classes (e.g. String)

"".d shows only dclone() as proposal instead of
.delete .delete! .detect .display .downcase .downcase!
.drop .drop_while .dump .dup

Is there a possibility to fix this?

Tested on OSX with Juno and DLTK 2.0 ruby 1.8.7, jruby 1.6.5, jruby 1.7.0
Windows with Helios and jruby 1.6.8

Just another question: Is it possible to enable code completion for java-classes in jruby-scripts?

Thanks

Al

That's strange. DLTK executes the following script to fetch the actual
members from the runtime environment:

http://git.eclipse.org/c/dltk/org.eclipse.dltk.ruby.git/tree/plugins/org.eclipse.dltk.ruby.launching/scripts/builtin.rb

Could you check if this script reports all the members in your environment?

That's not implemented yet.

I've extracted org.eclipse.dltk.ruby.launching_1.0.0.v20100524-0038.jar to the folder org.eclipse.dltk.ruby.launching_1.0.0.v20100524-0038 replaces the builtin.rb and added puts "..." to the builtin.rb and restartet eclipse with -clean -consoleLog.

Method-list is still not complete and I haven't seen any "..." in console.

Output is not printed to the console, it is processed by DLTK.
Could you execute that script manually from the command line to check
the output?

Also, if I remember correctly, result is cached for some time, so DLTK
might not executed it every launch.

The results from manual execution for 1.6.8 and generic ruby looks good (see atachments) - but downcase and upcase are still missing in proposals.

x_o in filename means that I had to enable object-space via argument -X+O

I've found out, that the model seems to bee stored in .metadata/.plugins/org.eclipse.dltk.launching/model.xmi
So I tried to delete the file - but after a restart the file was nearly empty (no value-tags).

Than I switched from ruby to jruby-interpreter (1.6. Cool

and restarted eclipse.
Now downcase und upcase are still missing but model.xmi contains the currect output (including down- and upcase).

model.xml includes now the correct output - but methods are still missing in proposals...

The problem is really because of the objectspace-flag.
On windows and osx I could get the proposals working with this steps:

1. modify jruby-script (jruby.bat or jruby.sh or jruby) and add the parameter -X+O to the ruby-executable (use JRUBY_OPTS or add it to jruby.exe)
2. use modified file as interpreter
3. if not done automatically add the libraries
4. delete workspace/.metadata/.plugins/org.eclipse.dltk.launching/model.xmi
5. restart eclipse

the deleted file in step 4 will be generated again and will contain the output of builtin.rb and now the proposals should work.

Now that I have a workaround for my problem (works on osx and windows) I have a new one.

I've required 'java' but all Methods from the are missing - e.g. to_java, java_method, ... (java_kind_of? is part of the proposals).
In the xml-File there is not method with "java" in name.

Can you also please explain how to use user-libs like the generated files from the builtin.rb?
If there is no code-completion for java I want to generate my own dummy-modules for code-completion.
