I15r

Goal

You prefer polishing your views 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 drive most of us nuts.

Summary

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]" />

Installation

Standalone

gem install i15r

In-app

Put the following in your Gemfile:

gem 'i15r', '~> 0.5.1'

Usage

Convert a single file

i15r path/leading/to/template

Convert all files in a directory (deep search)

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.

Dry run

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

i15r app/views/users --dry-run

Custom prefix

If you don't want the file path 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]" />

If you want the a prefix plus the file path to appear in the i18n message string, you can pass a prefix_with_path parameter:

i15r app/views/users/new.html.erb --prefix_with_path my_project

The above file will then contain:

<label for="user-name"><%= I18n.t("my_project.users.new.name") %></label>
<input type="text" id="user-name" name="user[name]" />

Override I18n.t function name

If you don't want to use the full I18n.t name, use the override_i18n_method parameter:

i15r app/views/users/new.html.erb --override_i18n_method t

This will cause output that normally results in:

<label for="user-name"><%= I18n.t("users.new.name") %></label>

to result in

<label for="user-name"><%= t("users.new.name") %></label>

No default translation

If you want to skip the default translation, you must add the --no-default flag

For example, if calling

i15r app/views/users/new.html.erb

results in

<label for="user-name"><%= I18n.t("users.new.name", :default => 'Name') %></label>

Adding the --no-default flag

i15r app/views/users/new.html.erb --no-default

results in

<label for="user-name"><%= I18n.t("users.new.name") %></label>

Design principles & suggested use

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.
