As an Engineer, I want Content Server to support Fluent

[data-sync-user]

• Modify content server code to add fluent support
• edit server/lib/i18n.js file to compile fluent instead of gettext
• remove helper from grunttasks-l10n-generate-pages.js
• replace bundling script in grunttasks/l10n-extract.js with fluent bundling script
• Create ftl file with single string in it
• update all instances of gettext template helper with fluent syntax

---

From Dave's original comment:

I'm seeing this issue as about 5 parts:

• edit server/lib/i18n.js file to compile fluent instead of gettext (3 points)
• address res.gettext in server/lib/500.js (3 points)
• remove helper from grunttasks-l10n-generate-pages.js (1 point)
• replace bundling script in grunttasks/l10n-extract.js with fluent bundling script (3 points)
• update all instances of gettext template helper with fluent syntax (3 points)

I believe we will need to merge this effort into master as a large group of commits, as I don't think it will work when partially implemented. So we may need to leave this issue as a large estimate and just try and hack it out over a sprint.

##1

We will most likely use handlebars-helper-fluent package to achieve this in server/lib/i18n.js

##2

I'm unsure about how to achieve the equivalent of 【 highlighted #ffffff 】res.【 end highlighted 】【 highlighted #6eff40 】gettext【 end highlighted 】【 highlighted #ffffff 】(【 end highlighted 】【 highlighted #4efff8 】'System unavailable, try again soon'【 end highlighted 】【 highlighted #ffffff 】),【 end highlighted 】 in the server/lib/500.js but this is a single string so we maybe could work around it. I'm reaching out to stasm today to see if there is a Fluent way to do this.

##3

I think that the helper in grunttasks/l10n-generate-pages.js will be rendered obsolete with [handlebars-helper-fluent package|https://github.com/alerque/handlebars-helper-fluent,] but will know more once I get to dig into it.

##4

The bundling that happens inside of grunttasks/l10n-extract.js could get hairy, but there are examples of the bundling in the fluent project, hopefully we can use the same snippet we are using inside of payments server. Again, I can't be certain with this one until I actually try it out.

##5

Going through and replacing strings and template tags to the fluent syntax should be rather painless, except for being monotonous. These sort of tasks can tend to take a while because of the amount hand edits that will need to be made. Though the edits themselves are practically brainless
