tree-sitter-fortran

What it is and what it does

tree-sitter-fortran is a language grammar binding that integrates Fortran parsing into the tree-sitter incremental parsing framework. It allows you to parse Fortran source code into a syntax tree suitable for code analysis, transformation, and tooling. The package is distributed as precompiled wheels for multiple platforms and Python versions, eliminating the need to compile the grammar yourself on most systems.

The package has no runtime dependencies and is designed for developers building Fortran analysis tools, linters, formatters, or IDE integrations. It adapts an existing Fortran grammar and is actively maintained, with recent releases and an active repository.

Use it for:

• Building a Fortran code formatter or linter that needs to parse and analyze Fortran syntax trees
• Creating IDE plugins or editor extensions that require Fortran syntax highlighting and navigation
• Developing static analysis tools to detect code patterns or metrics in Fortran projects
• Implementing automated refactoring tools for legacy Fortran codebases
• Generating documentation or call graphs from Fortran source code

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides a Fortran language grammar for tree-sitter, enabling incremental parsing and syntax analysis of Fortran code.

Yes, if you are building Fortran tooling or analysis systems. The package is actively maintained, has no known vulnerabilities, uses a permissive MIT license, and offers prebuilt wheels that minimize installation friction. It is a narrow-purpose library—useful only if you specifically need tree-sitter-based Fortran parsing—but solid for that use case.

Install

tree-sitter-fortran on PyPI

pip install tree-sitter-fortran

uv add tree-sitter-fortran

poetry add tree-sitter-fortran

Installing tree-sitter-fortran

Before you install

Medium install friction due to compiled wheels; prebuilt binaries available for common platforms (macOS, Linux x86_64/aarch64, Windows). Requires Python 3.9+. Active maintenance with recent releases.

License in practice

MIT license is permissive; you can use, modify, and distribute this package with minimal restrictions, provided you include the license notice.

Quickstart

pip install tree-sitter-fortran

import tree_sitter_fortran

Requires Python 3.9 or later; precompiled wheels available for macOS, Linux, and Windows on common architectures.

Verify before relying

• How to obtain and load the compiled Fortran grammar binding after installation
• Support for all Fortran standards (F77, F90, F95, F2003, etc.) or specific subset coverage
• Performance characteristics or parsing speed compared to other Fortran parsing approaches
• Whether npm tree-sitter-cli is required for runtime use or only for development
