[jbosstools-dev] AngularJS Eclipse

[Angelo zerr]

Hi Max, Alexey , Victor,

Today it supports it. See screenshots at

> Features#wiki-angular-expression-management
>

>and it does that without *running* the project javascript ? that is pure
tern parsed ?

Yes that"s it. But I think I don't manage the whole case. The angular tern
plugin must be improved.

>if yes - that is nice!

Thank's!

>I thought there were things in angularjs context that would not be
possible to extract from javascript?

With Tern plugin you can add you own logic when some methods is called. In
angular plugin case, it forces the $scope parameter used in the controller
to an instance of scope by injecting teh well methods $watch, etc

>Saying this in context of our experiment where we actually ask the browser
what is in the angular scope

get best of both worlds?
Yes I have seen that with your demo with Livereload.

The pros with this mean is that you get the well methods.
The cons with this mean is it doesn't work if your JS is not valid. I have
not managed that, but I would like to manage Hyperlink
for expression (ex : Ctrl+Click on "{{todo"  open the todo.js an select
$scope.todo). With Tern I can do that (because it's an AST)
I think you cannot do that with LiveReload?

>I tried installing OSX osgi bundle provided node.js and it seems to NPE
for me ;/
Yes it was a stupid error and Victor created an issue that I have fixed.

version.

should use the bundled one and

I agree with you. I must improve that, but I develop this plugin in my
spare time and I was very exciting to see tern integrated in Eclipse IDE.
So I have not worked a lot about the node.js topic.

We provide "embed" node.js that you must select when you install Tern IDE.
Perhaps it should better to have an install URL per OS?

As Alexey , Victor suggested me, node.js must be more customizable. I had
created this issue at https://github.com/angelozerr/tern.java/issues/4

>It just needs some enduser polish (i.e. users should not need to care
about different html editors,
>different node.js runtimes, it should "just work").
definitely!

>One concern we had was performance and portability.
>Does Tern handle larger projects of javascript well ?
By using node.js, tern can handle big file. But if you try to parse a big
framework like dojo it takes time.
Today Eclipse freezes, but I must do that in background.

>Can we avoid it have to parse

>can one just tell it to parse one file as oppose to all files all the time
?
When you open completion, it parses one time the whole files and after it
parses the current file.
I must improve the completion performance by using the "part" feature of
tern (not need to parse each time the whole file).

Today I use Tern for completion, find type in HTML editor. But Tern is
enable to manage search and refactoring.

>Have you found the bundled binaries to work across various OS's ?
No I have just Windows and my friend pascal has Linux.

Have a nice days.

Regards Angelo
