Atom and Sublime Text 2 / 3 Handlebars.js bundle

  • Colours of Handlebars expressions are selected to be in contrast with the surrounding HTML.
  • Handlebars expressions get syntax highlighting in HTML attributes.
  • Parameters passed to block expressions get syntax highlighting too.
  • Works both with individual template files and inline templates in script tags.
  • Key bindings for {{! Handlebars comments }} (Sublime only)
  • Tab triggers for
    • if{{#if }}
    • ifel{{#if }} {{else}}
    • el{{else}}
    • elif{{else if }}
    • un{{#unless }}
    • ea{{#each }}
    • wi{{#with }}
    • par{{> }} (for partials)
    • x-temp<script type="text/x-handlebars" data-template-name="$1"> (inline script tag in HTML files using the Ember recommended data-template-name attribute)
    • x-id<script type="text/x-handlebars-template" id="$1"> (inline script tag in HTML files using the legacy id attribute)

Since (as of February 2017) the syntax definitions in this repository are driving the highlights on Github and in Visual Studio Code, it's fair game to open issues related to either of these 😺

About Handlebars.js

It's a great JavaScript templating engine, based on Mustache, but amongst others adding the ability to precompile templates and to create custom helpers.

Official website: handlebarsjs.com

Sublime Text installation

Get it through Sublime Package Control.

If you haven't used it yet, just install it from the link above and then:

  1. Press Shift + Cmd + P (OS X) or Shift + Ctrl + P (Windows)
  2. Type install, to bring up the Package Control: Install Package option, and press Enter
  3. Look for Handlebars, and press Enter to install it.
  4. Choose Handlebars in the bottom right corner with one of your template files open (or in case you have inline templates use Handlebars instead of HTML, it's gracefully extending it so you shouldn't lose anything)
  5. Profit

Package Control will also auto-update the package from this point on!

Atom installation

  1. Open Preferences > Install
  2. Type Handlebars into the search field
  3. Click the Install button
  4. Disable the core language-mustache package so that it doesn't prevent this package to be used automatically with the supported file extensions

Known problems and workarounds

Sublime: No auto-complete on closing HTML tags (#23 & #49)

Problem: when closing an HTML tag, the tag name doesn't get auto-completed after typing / (or when using the Cmd + Alt + . (OS X) shortcut anywhere), even though this is the default behaviour with the HTML package.

Solution: installing the Tag package re-instates these functionalities and seems to be working well with this one.

Sublime: HTML tag pair doesn't get highlighted (#48)

Problem: moving the cursor over an HTML tag doesn't highlight its pair.

Solution: installing the BracketHighlighter package nicely solves the problem and adds much more powerful bracket matching than the built-in one.

Sublime: Expand selection to tag doesn't work (#47)

Problem: Expanding selection to tag doesn't work (Sublime command: expand_selection {"to": "tag"}).

Solution: if you install the Emmet package you can use the Match Tag Pair functionality by pressing Ctrl + D (OS X) or Ctrl + Shift + A (Windows).

Sublime: .sublime-build in the build system menu (#73)

Problem: a useless and confusing item named .sublime-build is added to the build system menu. This is because the package internally uses a custom build configuration to be able to target both Atom and Sublime and this gets exposed. Though it's only needed for development, Sublime doesn't seem to offer an option to hide this as the package gets installed.

Solution: delete the file from the package by running zip -d Handlebars.sublime-package ".sublime-build" in the folder it's installed or by any other means.

Testing / contribution

I've recently stopped heavily using Handlebars at my day job and became a father, so any contributions are more than welcome! I'm still using Github so will make sure to keep on being responsive on issues and pull requests.

There are some sample templates in test/ folder. It's possible to see the different supported and yet to be implemented use cases there.

Sublime Text

If you want to work on the package you should install PackageDev either from Github or from Package Control. With that you can edit the JSON version (grammars/Handlebars.json) and let it export the Plist (grammars/Handlebars.tmLanguage) with the ST Build System.

The nicest development setup I found so far is to have the package installed via Package Control and then symlinking the development Git repo to Sublime settings folder > Packages, which then overrides the installed one so you can toggle between them easily.

Another great trick I found out about recently is the Show scope name shortcut (Shift + Ctrl + P (OS X) or Shift + Ctrl + Alt + P (Windows)) which will display the language scope on the status bar based on where your cursor is. If you're getting tired of pressing all these keys all the time, there are a few brilliant packages which do this automatically like the more subtle ScopeAlways or the full on ScopeHunter – note: both need to be activated via the Command Palette.

Resources on ST / Textmate syntax definitions:

Atom

To see what scope Atom detects under the keyboard cursor, press Option + Cmd + P.

TODO: add proper testing based on specs in https://github.com/atom/language-mustache and https://github.com/Sneagan/atom-handlebars

Precompilation

This package does not offer any Handlebars precompilation functionality to keep things simple, but you can use Guard (which is a file system watcher) and Guard-Steering (a Handlebars precompiler from yours truly) to have all templates precompiled as you save them.

There's also a Guard package for Sublime if you want integration, but I don't personally use this as I'm happy with Guard running in an iTerm window I can access from anywhere.

There are of course Node.js / Grunt / Gulp based compilers too (like this and this), but I haven't personally used any yet for precompilation.
