A PromQL lexer for Pygments.

This Python package provides a Pygments lexer for the Prometheus Query Language. It allows Pygments and other tools (Sphinx, Chroma, etc) to highlight PromQL queries.

Installation

Using pip

To get the latest version from pypi.org:

pip install pygments-promql

Usage

Command-line

The following examples are using queries from tests/example.promql

Showing colorized output in a terminal:

pygmentize tests/example.promql

Or to generate a PNG file:

pygmentize -f png -O "line_numbers=False,style=monokai" -o example.png tests/example.promql

Python code

The following example:

from pygments import highlight
from pygments.formatters import HtmlFormatter
from pygments_promql import PromQLLexer

query = 'http_requests_total{handler="/api/comments"}'
print(highlight(query, PromQLLexer(), HtmlFormatter()))

will generate this HTML output:

<div class="highlight">
    <pre>
        <span></span>
	<span class="nv">http_requests_total</span>
	<span class="p">{</span>
	<span class="nl">handler</span>
	<span class="o">=</span>
	<span class="s">&quot;/api/comments&quot;</span>
	<span class="p">}</span>
	<span class="w"></span>
    </pre>
</div>

Use HtmlFormatter(noclasses=True) to include CSS inline styles on every <span> tag.
