prettierfier
Intelligently pretty-print HTML/XML with inline tags.
Decision gist · record as of 2026-08-14
No. The project is abandoned with its last release on 2019-07-22 and no maintenance since. While the code is simple and dependency-free, there is no path to bug fixes or compatibility updates. For active alternatives, consider using BeautifulSoup with a custom formatter or modern HTML/XML libraries with maintained prettification support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is frictionless—the package has no external dependencies and installs as a pure Python wheel.
- However, the project has been abandoned since its last release on 2019-07-22 with no updates since, so expect no maintenance or bug fixes going forward.

What it is and what it does
Prettierfier is a lightweight HTML and XML formatter that solves a specific problem: BeautifulSoup's prettify() method adds line breaks between every tag, which breaks inline elements like `<span>`, `<sup>`, and `<em>`. This package uses regex-based parsing to reformat markup more intelligently, preserving inline tags on the same line while still indenting block-level structure.
The package contains no external dependencies—it uses only the Python Standard Library—and offers two main functions: prettify_xml() for raw XML with configurable indentation, and prettify_html() designed to post-process BeautifulSoup output. It's a single-purpose tool for developers who need cleaner, more readable HTML/XML output without the whitespace bloat.
Use it for
- Post-process BeautifulSoup.prettify() output to remove unwanted line breaks between inline HTML tags.
- Format raw XML strings with intelligent indentation before writing to files or logs.
- Clean up HTML templates or scraped markup for human readability without breaking inline element layout.
- Debug HTML/XML structure by viewing it in a more compact, readable form than standard prettifiers produce.
