tern-node-express not working?

[ghost]

I must be missing something important in the installation process as tern-node-express is not working for me as shown in snapshot below.

Have you checked node-express in the Modules page : in other words in your .tern-project you should have node + node-express in the plugins section.

[ghost]

I don't have any .tern-project at project root. It's not a tern project but an express-mongoose project created manually from IDE (new folder then new files then Configure > Convert to Tern)

[angelozerr]

Without .tern-project tern.js cannot work. It contaisn list of JSON Type Definition and plugins that it must load.

I don't have any .tern-project at project root

If you have done " Configure > Convert to Tern", you have it but I suppose you don't see in the project explorer (like .project or .classpath). Use Navigation explorer or your system folder to see it.

If you don't have it, I don't understand, retrywith a new project.

I suggest you that you read https://github.com/angelozerr/tern.java/wiki/Tern-&-Node-Express-support to see how to activate tern node express

[ghost]

Configure > Convert to Tern didn't create a .tern-project but added tern nature and buid command to existing .project file as shown above: I think this is a flaw as a .tern-project file was expected.

I understand it's possible to do it otherwise but as long as you can select Configure > Convert to Tern then it should provide.

To reproduce the issue, create a directory from a terminal then promote it to project from IDE remote systems panel. At this stage you'll get an "empty" .project file.

Now convert the project to Tern: it inserts new value in existing .project file when it should create a new .tern-project file: this is the issue I am reporting.

[angelozerr]

It's normal, you should check node-express in the Modules preferences page, after that .tern-project will be created. But I think I will change this behaviour for 0.7.0 (see https://github.com/angelozerr/angularjs-eclipse/issues/108)

I think I must develop https://github.com/angelozerr/tern.java/issues/68 to avoid having an issue like you have created here.

[ghost]

I don't have a tern module page in preferences:

[angelozerr]

As I said you, please read https://github.com/angelozerr/tern.java/wiki/Tern-&-Node-Express-support you will see that it's project properties (and not global preferences).

[ghost]

Project properties: that makes sense - see below. I should be ready for mongodb/mongoose by now...

[ghost]

But no - still not working:

[ghost]

$ cat .tern-project {"ide":{"scriptPaths":[]},"libs":["ecma5"],"plugins":{"node":{},"node-express":{},"node-mongodb-native":{},"node-mongoose":{}}}iMac27:boilerplate

[ghost]

No auto-completion on tern-node-mongoose but this is probably same issue:

[ghost]

Am I correct assuming the red spot errors above are raised by tern ecma5 module?

[angelozerr]

I don't understand, it should work?

When you have problem with tern like your problem, you can activate tern console https://github.com/angelozerr/tern.java/wiki/images/EclipseIDE_TernConsoleProperty.png

After that you will see how to node is started and JSON request/response.

Am I correct assuming the red spot errors above are raised by tern ecma5 module?

No, those error comes from JSDT. If you wish to have tern errors, please read https://github.com/angelozerr/tern.java/wiki/Tern-&-Validation

[ghost]

I don't understand, it should work?

Well - that's what testings are about...

I don't get any trace in tern console.

After I typed res. I've got JSDT syntax error showing up instead of tern auto-completion.

[angelozerr]

Please send me your project. Thank's

I don't have jshint plugin installed — do we have any dependency broken here? See below:

I don't have jshint plugin installed — do we have any dependency broken here? See below:

it's an other issue than tern.java

Your project works for me. Tern console doesn't work?

Have you tried just to create a new project and add browser module and try document completion, etc ? is it working?

Try just to select node-express + node + ecma5 (not mongoose + mongodb)

Is tern responding with empty json?

[ghost]

When I insert res. within app.get() scope I am getting JSDT error but nothing in Tern terminal – like it was catched by JSDT before it could reach tern...

HTML seem to be working:

[angelozerr]

@nodeleaf I'm a little lost.

HTML seem to be working

HTML completion is not the same thing than tern completion.

Is tern responding with empty json?

Yes, it returns every time a JSON response.

It seems that your tern console works, no? I though your tern console didn' t work?

Ok, takes teh following sample :

var mongoose = require('mongoose');
mongoose. // here Ctrl+Space should shows completion items

Is this case works? If it doesn' work, have you a JSON request.response for completion. You should have this trace:

Tern request#completions:
