I experienced a popup in the IDE asking if I wanted to install and enable codeintel.

🎉 Thanks a lot for this pull request! 🎉 😄

I experienced a popup in the IDE asking if I wanted to install and enable codeintel.

Oh oh, this sounds like a bug. Are you sure that codeintel isn't already installed? I think it's supposed to be a "core plugin" of Cloud9, i.e. pre-installed with Cloud9 SDK.

Do you have a way to systematically trigger this pop-up, in order for me to reproduce this issue? I have never seen it myself, nor have I heard other users mentioning it.

Maybe you were trying to unlock some advanced Cloud9 feature? If so, I'd be super happy to help enable whatever you're trying to achieve 😄

+# Install dependencies to enable codeintel (https://github.com/c9/c9.ide.language.codeintel)
+RUN easy_install pip
+ && pip install -U pip
+ && pip install -U virtualenv


Nit: This will no longer be necessary when #97 is merged (it will already have the latest pip and virtualenv).

removed considering #97

Nit: This shouldn't be necessary. If you need python-dev to be installed in the ubuntu-dev image, please add it to the list of installed packages at the top of this dockerfile.

moved python-dev to the top of file, I think it is indeed needed, but I'm not 100% sure

Interesting, why are you renaming SilverCity to silvercity?

I don't know much, I have to check https://github.com/c9/c9.ide.language.codeintel, that's what they advocate to do

+ && pip install -U --no-index --find-links=/tmp/codeintel codeintel


Nit: Please delete the temporary /tmp/codeintel folder once you no longer need it. (And if some files need to be kept around for the installation to work, please move them somewhere under /home/user, e.g. as dotfiles or even better close to where it will be used, e.g. under a new folder in /home/user/.c9 as we do with noVNC).

They advocate to work under /tmp/ for this part, I assume pip does all the work, and nothing is necessary afterwards. done

All these steps look like a very complicated way to do pip install codeintel==0.9.3. Wouldn't such a simple command work as well?

Last commit fixes my mistakes and your nits. This should be working, but better test twice!
I was talking about the popup which is triggered when the IDE thinks you're looking for snippets or autocompletion. One way to trigger it (from the IDE of any actual or fresh-spawned container), is to create and save a PHP file, then type '<?php', then '$'. The popup should show up asking you if you want to install codeintel.

I need more testing, the codeintel server doesn't appear to be running...

Thanks for updating this pull request! 😄

I noticed that the codeintel repository is already checked-out in c9/core/plugins: https://github.com/c9/core/tree/master/plugins/c9.ide.language.codeintel so I find it strange that c9/core/scripts/install-sdk.sh doesn't already install such external dependencies. Oh well, at least we'll be doing that for Janitor containers (thanks!)
