local_time_helper.cr

Crystal implementation of view helper from https://github.com/basecamp/local_time, with one small Crystal-specific improvement to save you some typing (both kinds): a nil_message option (a string returned when the provided time argument is nil; typically something like "never", or just "").

Installation

Add this to your application's shard.yml:

dependencies:
  local_time_helper:
    github: anamba/local_time_helper.cr

Add the local-time js to your project using npm or yarn.

Usage

Made to be used with Amber, but will probably work fine in other situations. Require/include like other helpers.

require "local_time_helper"

include LocalTimeHelper

<%= local_time(Time.utc(2018, 11, 21, 6), format: "%B %e, %Y %l:%M%p") %>

produces:

<time data-format="%B %e, %Y %l:%M%P" data-local="time" datetime="2018-11-21T06:00:00Z">November 21, 2018  6:00am</time>

See specs for more helper usage examples. Note that Crystal's %p and %P are swapped, which makes plenty of sense, but is different from other implementations (including JavaScript and Ruby).

Development

It's not a complete implementation of everything the ruby gem does, just enough to get the specs to pass (translated the relevant tests from the original). Contributions welcome if it doesn't support the options you need.
