Installation

pip install pygments-liquid2

This package uses the Pygments plugin entry point, so, if its installed in your Python environment, additional Liquid lexers will be available automatically. Confirm this by listing lexers with one of the following methods.

Listing lexers on the command line:

pygmentize -L lexers | grep -i liquid

* html+liquid, htmlliquid:
    HTML+Liquid (filenames *.html.liquid, *.htm.liquid, *.xhtml.liquid)
* html+liquid2, html+liquid, htmlliquid:
    HTML+Liquid2 (filenames *.html.liquid, *.htm.liquid, *.xhtml.liquid)
* liquid2, liquid:
    liquid2 (filenames *.liquid)
* liquid:
    liquid (filenames *.liquid)
* liquid:
    liquid-std (filenames *.liquid)

Listing lexers with Python

from pygments.lexers import get_all_lexers

all_lexers = get_all_lexers(plugins=True)
liquid_lexers = sorted(lexer for lexer in all_lexers if "liquid" in lexer[0].lower())

for name, aliases, _filenames, _mimetypes in liquid_lexers:
    print(f"{name}: {aliases}")

Available lexers

After installation, these Liquid lexers should be available.

liquid

The Liquid lexer built in to Pygments.

This lexer is importable from Python using from pygments.lexers import LiquidLexer.

liquid-std

An alternative Liquid lexer for Shopify/Liquid syntax. This lexer makes the following changes over the built-in Liquid lexer.

• Add support for nested block comments (those with balanced comment/endcomment tags).
• Add support for whitespace control, like {{- some.thing -}}.
• Add support for inline comment tags, like {% # some comment %}.
• Add support for {% liquid %} tags.
• Add support for bracketed variable and index, like foo[bar]["with a space"][1].
• Allow tag and output expressions to span multiple lines.
• Remove the logical not keyword.

This lexer is importable from Python using from pygments_liquid2 import StandardLiquidLexer.

html+liquid

A DelegatingLexer for highlighting HTML with standard Liquid markup.

This lexer is importable from Python using from pygments_liquid2 import HtmlLiquidLexer.

liquid2

A Liquid lexer with the following extended syntax over liquid-std described above.

• Add support for new style comments, like {# some comment #}.
• Add support for template strings, like {{ "Hello, ${you | upcase}" }}.
• Add some extra keywords.
• Add support for scientific notation for floats and integers.
• Add more whitespace control characters, like {{+ some.thing ~}}.

This lexer is importable from Python using from pygments_liquid2 import Liquid2Lexer.

html+liquid2

A DelegatingLexer for highlighting HTML with Liquid2 markup.

This lexer is importable from Python using from pygments_liquid2 import HtmlLiquid2Lexer.

Lexer priority

liquid2 and html+liquid2 are given a higher priority than the Liquid lexer built-in to Pygments and liquid-std. So, when using Pygments functions like get_lexer_for_filename() and guess_lexer(), you should expect to get a Liquid2 lexer over a standard Liquid lexer.
