Forum: Rails I18n Rails 3.x, Ruby 1.9.x + HAML = Terror?

Hi everyone,

It seems ruby_parser is required to parse HAML files for gettext msgids
with the gettext:find rake task from gettext. However, ruby_parser 
doesn't
seem to work on Ruby 1.9.x.

So is it impossible to extract gettext msgids with reasonably new Rubies
and HAML?

Cheers,

Ramn

Hi again,

Perhaps some more context. I've added the gems to my Gemfile as 
instructed
here: https://github.com/grosser/gettext_i18n_rails

I've also added ruby_parser because that readme says it's needed to 
parse
HAML. Yet rake gettext:find explodes on any and all HAML files:

Error parsing app/views/admin/contexts/_form.html.haml
rake aborted!

Tasks: TOP => gettext:find


The file it's complaining about is:

https://github.com/zhdk/madek/blob/next/app/views/...

It  seems to be valid HAML, it works fine in our app.

Any ideas?

Cheers,

Hi yet again,

Sorry for replying to my own post, but I found a workaround: It seems 
that
ruby_parser cannot deal with Ruby 1.9 syntax yet, so if your HAML files
contain any Ruby 1.9 syntax in their Ruby, it will break gettext's
gettext:find rake task (it relies on ruby_parser).

If ruby_parser ever starts supporting 1.9 syntax or if gettext starts 
using
a different Ruby parser, this limitation could go away. So until then, 
no
Ruby 1.9 in your HAML, even on Ruby 1.9.

Cheers,

Ramn
