[jbosstools-dev] Updating Tern.java & AngularJS Eclipse IDE?

[Angelo zerr]

Hi Guys,

At first you can see new feature of Tern 0.7.0 at
https://github.com/angelozerr/tern.java/wiki/New-and-Noteworthy-0.7.0

There were too big refactoring since MyEclipse PR to improve tern file
synchronization.

Today the big problem with tern.java is when you have a lot of JS files in
your project (with bower tool you can have a lot of JS files).

If you configure correctly your tern script path
https://github.com/angelozerr/tern.java/wiki/Tern-Script-Path you can set
the folder which contains JS you need to parse with tern.

BUT since 0.6.0, tern script path is configured by using JSDT Install Path,
and it can be a problem, because :

 * in 0.6.0, the JSDT Install Path -> Tern script path was not very
managed. Problems comes from with lib configuration. In this case, project
folder is used. I have fixed that in 0.7.0
 * JSDT Install Path -> Tern script path must be improved again like
managing exclude script path
https://github.com/angelozerr/tern.java/issues/168

There is a problem too when JS file is removed (tern server keep this file
in memory, although it is removed) See
https://github.com/angelozerr/tern.java/issues/157

In other words:

 *  tern.java must improve again tern file synchronization.
 * don't parse the whole JS files of your project if your project has a lot
of JS files. To fix this problem :
  => JSDT Install Path -> Tern script path should be improved
  => tern file synchronization should be done in background
  => tern is able to support condense of JS files, but it is not very
stable. I think in the future, it should be very cool if we can condense
for the first time, JS files, store it in file system (do the JS files
analyze just the first time)

In 0.8.0, I have the intention to support completion, validation,
hyperlink, hover inside string. See my work for tabris
https://github.com/eclipsesource/tabris-js/issues/180#issuecomment-65137514
and node.js require https://github.com/marijnh/tern/pull/430

I will try too to develop a tern builder for tern-lint. See
https://github.com/angelozerr/tern.java/issues/174

Don't hesitate to create issues or PR to improve tern.java, thank's for
your help!

Regard's Angelo
