Not working in erb files

[lucas-clemente]

Tab expansion doesn't work in ERB files. I had this working through #43 some time ago, but since then the code got replaced and I don't know what's going on now.

Got the same behavior in handlebars (.hbs) files. Is there a way to activate emmet for additional file extensions other than html/css?

[sergeche]

You can use ⌘E to expand abbreviations anywhere: https://github.com/emmetio/emmet-atom#default-keybindings
Tab key requires additional logic to not interfere with default snippets

[lucas-clemente]

Is there a reason why syntax detection is based on grammar, not on scope? That should allow it to work in anything that resembles HTML.

[sergeche]

You may want to use default snippets in HTML scope of ERB-files to create ERB-structs like <%= ... %>

[lucas-clemente]

Ah, I see. Do you know how this problem is solved e.g. in the sublime plugin? Do they have expansion priorities or sth?

[sergeche]

In ST it’s impossible to properly solve this issue (e.g. make distinction between static built-in snippets and dynamic Emmet abbreviations) due to lack of API.

But it quite possible in Atom due to its open-source nature: it’s possible to contribute some API points to default Atom’s snippets package to retrieve all matched snippets for given scope

[lucas-clemente]

Sounds neat. Is this something that is being worked on, or should I have a look?

[sergeche]

No, I’m not working on it

You can use ⌘E to expand abbreviations anywhere

thanks, ⌘E is working fine.

[davidrunger]

The shortcut seems to be shift + ⌘ + e now.

Edit: Ahh, of course. Nothing has changed. ⌘ + E == shift + ⌘ + e.

[timohofmeijer]

I'd really like tab expansion in handlebars files. ⌘E sucks. Doen anyone know a way how to get this to work?

[silvenon]

From v2.3.0 you can easily enable the Tab key for any language. Read this for more info.

Thanks @silvenon 👍 Works!

File -> Open Your Keymap

'atom-text-editor[data-grammar="text html mustache"]:not([mini])':
    'tab': 'emmet:expand-abbreviation-with-tab'

[natecox]

@silvenon @brunowego Thank you, exactly what I was looking for!

[adeyahya]

add this to keymap.cson

'atom-text-editor[data-grammar="text html erb"]:not([mini])':
    'tab': 'emmet:expand-abbreviation-with-tab'

data-grammar for erb is

text html erb

[weekeight]

I just can not find the keymap.cson file in st2，there is no open your keymap menu item, who can tell me?

[silvenon]

ST2 as in Sublime Text 2? This is an Atom plugin 😁

[Swelly]

I'm a ST3 user and I'm trying to enable erb snippets within Emmet as well @weekeight. I'm not so hopeful after seeing @sergeche's post haha

[OneHoopyFrood]

@adeyahya I show the data-grammar as text html ruby and the functionality reflects this. Can anyone else confirm?

[alobintechnologies]

Try with this: It's working for me.

'atom-text-editor[data-grammar="text erb basic"]:not([mini])':
'tab': 'emmet:expand-abbreviation-with-tab'

[alobintechnologies]

my keymap.cson is:

'atom-text-editor[data-grammar="text html basic"]:not([mini]), atom-text-editor[data-grammar~="text erb basic"]:not([mini])':
'tab': 'emmet:expand-abbreviation-with-tab'

[samuelpismel]

This one works for me (Atom 1.14.2):

'atom-text-editor[data-grammar="text html ruby"]:not([mini])':
    'tab': 'emmet:expand-abbreviation-with-tab'

@brunowego's comment should be in the docs.
