You probably prefer making your views better to manually replacing strings in them to make them i18n compatible. If I got that one right, i15r is for you. It automates the process that would otherwise drove most of us nuts.
I15r (Internationalizer) searches for all the non-i18n texts in your erb and haml templates in the given file/directory and replaces them with I18n messages.
The message string is based on the path of the file in which the text was found and the text itself that was replaced.
E.g
(in file app/views/users/new.html.erb)
<label for="user-name">Name</label>
<input type="text" id="user-name" name="user[name]" />
will be replaced by:
(in file app/views/users/new.html.erb)
<label for="user-name"><%= I18n.t("users.new.name") %></label>
<input type="text" id="user-name" name="user[name]" />
and
(in file app/views/member/users/edit.html.erb)
<label for="user-name">Name</label>
<input type="text" id="user-name" name="user[name]" />
will be replaced by
(in file app/views/member/users/edit.html.erb)
<label for="user-name"><%= I18n.t("member.users.edit.name") %></label>
<input type="text" id="user-name" name="user[name]" />
gem install i15r
Put the following in your Gemfile:
gem 'i15r', '~> 0.5.1'
i15r path/leading/to/template
i15r path/leading/to/directory
All files with an erb or haml suffix in that directory or somewhere in the hierarchy below will be converted.
By default, i15r overwrites all the source files with the i18n message strings it generates. If you first want to see what would be replaced, you should do:
i15r app/views/users -n
or
i15r app/views/users --dry-run
If you don't want the filename to appear in the i18n message string, you can pass a prefix parameter that will be used to generate the message strings. For example if you have the following in a file called app/views/users/new.html.erb:
<label for="user-name">Name</label>
<input type="text" id="user-name" name="user[name]" />
And then call:
i15r app/views/users/new.html.erb --prefix my_project
The file will then contain:
<label for="user-name"><%= I18n.t("my_project.name") %></label>
<input type="text" id="user-name" name="user[name]" />
I15R takes the 80-20 approach. It focuses on finding most of the text that needs to be replaced in your templates and replacing them with the correct i18n strings. It forgoes the 100% hit rate in favor of getting the 80% right and keeping the code (relatively) simple. Consequently, please report any bug that concerns strings that should not have been replaced or ones that have been replaced incorrectly.
A good practice is to first run i15r with the --dry-run option to see what would be replaced and then run it for real, without the --dry-run option. You can also run it on files that have already been "internationalized" since i15r will just skip those rows.
