HogQL parser for internal PostHog use
Decision gist · record as of 2026-08-14
Yes, if you are building on PostHog or need to parse HogQL syntax on macOS or Linux. The package is actively maintained, has no known vulnerabilities, uses a permissive MIT license, and ranks in the top 5000 PyPI packages by downloads. Install friction is moderate due to platform and architecture constraints—Windows users cannot use it. Verify that the Python API matches your needs before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires macOS or Linux; Windows is not supported.
- Python 3.10 or later required.

What it is and what it does
HogQL Parser is a native C++ extension for Python that parses HogQL query expressions, SELECT statements, and Hog programs into abstract syntax trees. It wraps an ANTLR4-based parser shared with a WebAssembly version for JavaScript. The package is designed for internal PostHog use and supports Python 3.10 through 3.13 on macOS and Linux platforms.
The parser accepts HogQL syntax—a SQL-like query language—and produces structured ASTs that can be consumed by downstream tools. It has no runtime dependencies and installs via prebuilt wheels for supported architectures, though Windows is not supported. The package is actively maintained and has seen recent releases.
Use it for
- Parse HogQL expressions in PostHog analytics pipelines to validate or transform user queries
- Build development tools or IDE plugins that need to understand HogQL syntax and structure
- Integrate HogQL query parsing into backend services running on Linux or macOS infrastructure
- Generate ASTs for query optimization or analysis in analytics platforms

More Text Processing packages
A drop-in replacement for Python's standard `re` module that adds advanced regex features like nested sets, fuzzy matching, lookaround in conditionals, and full Unicode case-folding while maintaining backward compatibility.
pyparsing provides a library for building text parsers directly in Python code using composable grammar classes, handling quoted strings, whitespace variation, and embedded comments without regex or lex/yacc.
Install it if you need to parse text or define grammars programmatically.
fonttools manipulates font files in multiple formats (TrueType, OpenType, AFM, Type 1, Mac-specific) and includes TTX, a tool to convert fonts to and from XML text format.
Install it if you need to read, write, or manipulate fonts programmatically or via the TTX command-line tool.
Docutils converts plaintext documentation in reStructuredText format into multiple output formats including HTML, XML, and LaTeX using a modular processing system.
RapidFuzz provides fast fuzzy string matching using Levenshtein Distance and related metrics, implemented mostly in C++ with Python bindings for rapid similarity scoring and approximate string matching.
Install it if you need fuzzy string matching; it's a solid replacement for FuzzyWuzzy with better licensing and performance.
tinycss2 parses CSS strings into token and block objects, and generates CSS strings from those objects, following the CSS Syntax Level 3 specification without enforcing specific properties or values.
Install it if your project requires CSS tokenization or syntax manipulation.
