AWS CloudFormation Editor for Eclipse appears not to work about aws-toolkit-eclipse

[fulghum]

Hey Henrich, sorry for the slow response on this one. The functionality between Visual Studio and Eclipse is a little different, but the major features should be fairly comparable. If you can give us some more specific cases where the editor isn't working as you'd expect, then we can repro and prioritize the fix. The example about changing "true" to "tr sd ue" is a good one we can start with.

When I enter CTRL-CMD here https://gist.github.com/henrjk/ced5e3a46dc3d9c015cd#file-cloudformer-template-json-L3 I get the https://gist.github.com/henrjk/ced5e3a46dc3d9c015cd#file-eclipse-error.

Here to repeat

I have not seen this particular exception before.

After renaming file cloudformer.template.json to cloudformer.template.json I see a proper icon. See screenshot:

Now content assist on the top level appears OK but when selecting Conditions an error is introduced as shown in the screenshot.

On the previous comment when I try CTRL+CMD on inside the existing "Properties" of vpc3d2adc54 I do not get content assists, only beeps. There are no new errors in the 'Error Log' either.
Also I don't see tooltips either when hovering anywhere.

The only place beyond the one mentioned in previous comment I managed to get content assist is with CTRL+CMD inside "AWS::EC2::VPC". This works pretty well as the list of choices changes depending on where the cursor is and there is also help text.

If I introduce syntactical JSON errors I see problem markers in the editor and error squiggles:

However the Problems View remains empty. Perhaps this is expected.

While typing in a new property no content assist is available nor or is nonsensical content marked as errors (see Foo World):

We had just released an enhancement version of the CloudFormation editor in Eclipse v201707121824.

Feel free to try this out and let us know what further features you want us to add to the editor. We'd glad to hear your feedback.
