[Feature request] Twig var autocomplete

[ideea]

[adrienbrault]

How is that supposed to work ?

A template can be called from many different places and variables could contain objects, arrays ... etc

[ideea]

Its working somehow in eclipse plugin: https://github.com/pulse00/Symfony-2-Eclipse-Plugin

[ideea]

And all available variables are stored in _context variable. You can dump, for example, to see them:
dump(_context)

[Haehnchen]

the plugin only search for the matching shortcut controllermethod of the twig file and resolve the return statement, so no magical stuff :)
i will first try on the twig global function, to see if yaml is fully implemented in phpstorm

@hhamon suggested on twitter to autocomplete app.request, app.user etc https://twitter.com/hhamon/status/357469386325495808

[hhamon]

All default app variables are know:

app.request
app.security
app.session
app.user
app.debug
app.environment

You can also add new globals by tweaking the app/config/config_*.yml files:

# app/config/config.yml
twig:
    globals:
        pi: 3.14

In this case you can do app.pi in your templates.

You can also add globals from Twig extensions classes, but for these ones, I don't think we can easily guess them from the IDE.

i was trying it before, but there is no "type" support in twig of phpstorm. just giving app.request is easy but providing method completing after this hard. So this one need some hacks with autocomplete and goto provider, but its possible...

dont forget services:

twig:
    globals:
      service: @service

Be careful. @hhamon was wrong. Setting a pi global variable will not provide app.pi. It will provide pi.
app is not a container for global variables. It is a single global variable referencing an instance of Symfony\Bundle\FrameworkBundle\Templating\GlobalVariables which has a few getters to give access to several objects

[hhamon]

Good catch!

[Haehnchen]

so globals are in and more ...

{# variable_name \Foo\Bar #}

Still dont work - 0.11.92 in PHPStorm 141.1408

I'd tried add this in yml files for all environments with/out includes (also we have changed path to cache folder - app/cache/dev/appDevDebugProjectContainer.xml actually in app/var/cache/dev/myruDevDebugProjectContainer.xml)

parameters:
  some: 22.2
twig:
    globals:
        some_variable: "Hello"
        another_variable: %some%
        set_of_vars: [1, 2, 3]
        list:
            some: 2

No suggest for

# twig
{{ so }}

and "Can't find declaration".

[marapper]

app/var/cache/dev/myruDevDebugProjectContainer.xml contains

14796-      <call method="addGlobal">
14797-        <argument>some_variable</argument>
14798-        <argument>2</argument>
14799-      </call>
