Python 3.8+ Compatibility Fixes for compmake

1. Deprecated imp Module

The imp module was deprecated in Python 3.4 and removed in Python 3.8+, causing errors like:
ImportError: No module named 'imp'
Fixed by:

• Replaced direct imp import with conditional import based on Python version
• For Python 3: from importlib import reload
• For Python 2: import imp; reload = imp.reload
• File modified: src/compmake/plugins/reload_module.py

2. Deprecated inspect.getargspec()

The inspect.getargspec() function was deprecated in Python 3 in favor of inspect.getfullargspec(), causing errors in Python 3.8+:AttributeError: module 'inspect' has no attribute 'getargspec'
Fixed by:

• Updated code to conditionally use the appropriate function based on Python version
• For Python 3: inspect.getfullargspec()
• For Python 2: inspect.getargspec()
• Files modified:
  • src/compmake/events/registrar.py (in register_handler() and broadcast_event() functions)

3. Invalid Escape Sequences in Regular Expressions

Fixed SyntaxWarnings related to invalid escape sequences in regular expressions:
SyntaxWarning: invalid escape sequence '\A'

• Converting string patterns to raw strings to avoid escape sequence issues
• '\A' → r'\A'
• '\Z' → r'\Z'
• '\x1b\[..?m' → r'\x1b\[..?m'
• Files modified:
  • src/compmake/utils/wildcards.py
  • src/compmake/utils/strings_with_escapes.py

These changes have been tested by:

1. Installing the patched compmake version
2. Verifying it works with Python 3.8+ without import errors
3. Testing functionality that depends on the patched features

Backward Compatibility

All changes maintain backward compatibility with Python 2 through the use of conditional imports and execution paths based on the Python version.

Installation

# Clone the repository
git clone https://github.com/YOUR_USERNAME/compmake.git

# Install the patched version
pip install -e ./compmake

1. Fixing the deprecated imp module usage in plugins/reload_module.py by:

   • Adding conditional imports for Python 2 vs. Python 3
   • Using importlib.reload for Python 3 instead of imp.reload

2. Fixing inspect.getargspec() usage in events/registrar.py by:

   • Using conditional code to call the appropriate function based on Python version
   • For Python 3: inspect.getfullargspec()
   • For Python 2: inspect.getargspec()

3. Fixing invalid escape sequences in regular expressions:

   • Updating string patterns in utils/wildcards.py to use raw strings (r'\A' instead of '\A')
   • Updating string patterns in utils/strings_with_escapes.py to use raw strings
