TMDLParser

A Python library designed to parse and process TMDL (Table Metadata Description Language) files

About The Project

TMDLParser is a Python library designed to parse and process TMDL (Table Metadata Description Language) files. It provides a structured way to handle data descriptions, properties, and calculations with an easy-to-use API.

• Parses TMDL files into structured Python objects.
• Handles multiple levels of nested properties.
• Supports detailed descriptions, elements, properties, and calculations.
• Easily integrates with other Python applications.
• Lightweight and easy to install.

Getting Started

Install the library directly from PyPI:

pip install tmdl-parser

Prerequisites

python>=3.10 Library uses only standart library and no 3th party.

Usage

Basic Example

from tmdlparser import TMLDParser

# Initialize the parser with a TMDL file path
parser = TMLDParser("path/to/tmdl/file.tmdl")

# Print the parsed structure
print(parser)

Results:

Description: Table Description
Element: Table Name
Properties:
    ----------
    Description: Column Description
    Element: Column Name
    Props: ['property_1', 'property_2']
    Calcs: ['calculation_1']
Calculation: ['Calculation Formula']
--------------------

Export formats

The parser can also return the parsed structure as a plain Python dictionary or as a pandas DataFrame for downstream analysis:

from tmdlparser import TMLDParser

parser = TMLDParser("path/to/project.pbip")
parser.parse_all_tables()

# Nested dict, ready for json.dumps() or any downstream processing.
data = parser.to_dict()

# Flat DataFrame (one row per TMDL entry, nested entries get parent_element set).
df = parser.to_dataframe()

# Or keep only the top-level entries with raw properties:
df_top = parser.to_dataframe(flatten=False)

to_dataframe() requires pandas, which is an optional dependency. Install it with:

pip install tmdl-parser[pandas]

Roadmap

• Publish to pip
• Create tests
• Better return format for parsed files
