Support i18n mount_at_root option in permalinks

[pmk1c]

It would be great if Middleman Blog could handle the mount_at_root option given by the :i18n extension. For example by providing an option to prepend the i18n path root to the articles permalinks.

In one of our projects we have a configuration like this:

# config.rb
activate :i18n, mount_at_root: :de, langs: [:de, :en]

activate :blog do |blog|
  blog.name = 'blog'
  blog.prefix = "{lang}/blog"
  blog.permalink = "{title}.html"
  blog.sources = "{title}.html"
end

With this configuration all german ("de") pages are mounted at root, but the german blog posts are found under /de/blog/…

So for reaching our goal, that the blog posts can be found under /blog/… while the english blog posts remain at /en/blog/…, we use the following configuration and prepend the i18n path root within our own extension:

# config.rb
activate :i18n, mount_at_root: :de, langs: [:de, :en]

activate :blog do |blog|
  blog.name = 'blog'
  blog.sources = "{lang}/blog/{title}.html"
  blog.permalink = "{blog}/{title}.html"
end

activate :blog_prepend_i18n_path do |config|
  config.blog_name = 'blog'
end

This is the extensions code: https://gist.github.com/pmk1c/f192dd30edba2a25c9f352d1e8df8234

So one way for Middleman Blog to fully support :i18n could be to add a configuration option, that prepends the i18n path root to the permalinks of the articles. Leading to a configuration like this:

# config.rb
activate :i18n, mount_at_root: :de, langs: [:de, :en]

activate :blog do |blog|
  blog.name = 'blog'
  blog.sources = "{lang}/blog/{title}.html"
  blog.permalink = "{blog}/{title}.html"
  blog.prepend_i18n_path_root = true
end

But maybe there are better options to support mount_at_root. I'm open for discussion and I'd like to send a PR for this, if we find a solution.

Hello,
thank you for this post.
It is just what I'm looking for.
However I'm relatively new to ruby, so I need a little help in order to install your extension.
Here what I've done:
I've executed command middleman extension blog_prepend_i18n_path
Then I've replaced file in lib directory with your own file (that is blog_prepend_i18n_path.rb).
Then I've added values in blog_prepend_i18n_path.gemspec files and I've executed bundle install.
All went fine.
But extension seems not to be installed in my system, so middleman give an error when building.

Is there anything I forgot?

Thank you.

Regards
Pietro

You don't need to run middleman extensions blog_prepend_i18n_path. All you have to do is to copy our extension to i.e. your lib folder. Then you can require it in your config.rb file:

# config.rb
require 'lib/blog_prepend_i18n_path'

activate :blog do |config|
  config.blog_name = 'blog'
  …
end

activate :blog_prepend_i18n_path do |config|
  config.blog_name = 'blog'
end

We won't be publishing this hack as a gem. Since we'd rather have middleman-blog handle this in a less hacky way.
