Installation

Package Control

The best way is to install it via Package Control. Once you have Package Control setup in Sublime Text, open the command palette and search for Package Control: Install Package. Search for Jinja2 and install it. Package Control will take care for of automatically updating the package for you if there are new releases.

You can also use Package Control: Add Repository. Copy the github url (without the .git at the end) and enter it into the input panel that pops up at the bottom when you select Package Control: Add Repository. Now use Package Control: Install Package and search for Jinja2 and install it.

Documentation

How to use this package ?

By default, this package supports the following Jinja extensions: j2, jinja, jinja2, html.j2, html.jinja, html.jinja2, htm.j2, htm.jinja, htm.jinja2.

Since a user can have more than one templating language package installed, this package doesn't support .html directly. To get highlighting for .html files with Jinja code and all the other features this package provides, you can follow any of the two approaches given below

1. Go to the bottom right status bar item that displays information on current syntax and click on that when the currently open file is any .html file. From there go to Open all with current extensions as ... and scroll to select Jinja. You should now be good to go.

2. When the currently open file has any of the aforementioned file extensions, from the main menu, go to Preferences -> Settings -- Syntax Specific. This should open a 2 column new window, with the default settings on the right and a user settings on the left. In the user settings, add the following, save & close.

{
    "extensions": [
        ".html"
    ]
}

Key bindings

• The key bindings are configured so that pressing shift + { twice will automatically add spaces on both sides for the inner brace expression block & place the cursor in the center, like so {{ | }}.
• |||ly pressing shift + % within {} will add spaces on both sides of the inner % like so {% | %}
• You can use ctrl + / for inserting Jinja style line comments (## This is a line comment)
• Similarly, use ctrl + shift + / for block style comments ({# This is a block comment #})

Auto completions

No special configuration is required for completions to show while typing or snippets to expand.

Completion behaviour of the primary syntax applies to normal content. Default behaviour of ST involves distinction between source and text scopes.

• source (CSS, JavaScript, JSON, YAML): completions display while typing.
• text (HTML, Markdwon, Text, XML): only snippets expand by pressing tab key.

Content of {% %} and {{ }} tags is scoped source.jinja to enable completions while typing.

Snippets

Basic snippets for each keyword are provided to create expressions without bothering with {% %}.

Prefixed with j basic snippets for most common control structures are provided.

For more, please follow the official documentation on snippets to create your own.

Snippets can be disabled (ignored) by adding the following to Preferences.sublime-settings:

{
    "ignored_snippets": ["Jinja2/*"]
}

Troubleshooting

Jinja2 extends Sublime Text's CSS, HTML, JavaScript, JSON, Markdown, XML and YAML syntax definitions.

If Jinja2 syntax highlighting doesn't work and console displays syntax errors,

1. check if required bundled packages are enabled.
2. remove any out-dated syntax override.

Enable bundled packages

1. Open Command Palette using ctrl+shift+P or menu item Tools → Command Palette...
2. Choose Package Control: Enable Packages
3. Find CSS and hit Enter
4. Repeat the steps for JavaScript, HTML …

Remove overrides

1. call Menu > Preferences > Browse Packages..
2. Look for CSS, HTML, … folders
3. Remove them or at least delete any syntax definition in them
