detextive 1.0

Detects textual content.

🕵️ A Python library which provides consolidated text detection capabilities for reliable content analysis. Offers MIME type detection, character set detection, and line separator processing.

Key Features ⭐

🔍 MIME Type Detection

Intelligent content-based detection using magic bytes with file extension fallback for comprehensive format identification.

📝 Character Encoding Detection

Statistical analysis with UTF-8 optimization and validation through decode operations for reliable text processing.

📄 Line Separator Processing

Cross-platform line ending detection and normalization supporting CR, LF, and CRLF formats with mixed-content handling.

✅ Textual Content Validation

Smart classification of MIME types and content reasonableness assessment using control character and printability heuristics.

Installation 📦

Method: Install Python Package

Install via uv pip command:

uv pip install detextive

Or, install via pip:

pip install detextive

Examples 💡

Basic Usage

MIME Type and Charset Detection:

import detextive

with open( 'document.txt', 'rb' ) as file:
    content = file.read( )

# Individual detection
mimetype = detextive.detect_mimetype( content, 'document.txt' )
charset = detextive.detect_charset( content )

# Combined detection
mimetype, charset = detextive.detect_mimetype_and_charset(
    content, 'document.txt' )
print( "Detected: {mimetype} with {charset} encoding".format(
    mimetype = mimetype, charset = charset ) )

Line Separator Processing:

import detextive

content = 'Line 1\r\nLine 2\rLine 3\n'
separator = detextive.LineSeparators.detect_bytes( content.encode( ) )

# Normalize line separators to Python standard.
normalized = detextive.LineSeparators.normalize_universal( content )

# Convert to specific line separators.
native = detextive.LineSeparators.CRLF.nativize( normalized )

Content Classification:

import detextive

# Check if MIME type represents textual content
detextive.is_textual_mimetype( 'application/json' )  # True
detextive.is_textual_mimetype( 'image/jpeg' )        # False

# Validate text content from bytes
detextive.is_textual_content( b'Hello world!' )      # True
detextive.is_textual_content( b'\x00\x01\x02\x03' )  # False
