Summary of Changes

Files Reformatted:

Core library files:

• libxml2/xml2doc.pony - Fixed multiline function signatures, removed parentheses around conditions, split long lines
• libxml2/xml2error.pony - Fixed match statement indentation (pipes align below match keyword)
• libxml2/xml2node.pony - Fixed multiline function signatures, removed parentheses around conditions, split long lines
• libxml2/xml2xpathobject.pony - Fixed multiline function signatures, removed parentheses around conditions, split long lines
• libxml2/xpathtype.pony - Fixed type alias formatting with proper alignment
• libxml2/_test.pony - Already compliant, no changes needed

Test files:

• libxml2/_tests/basic_tests.pony - Already compliant, no changes needed
• libxml2/_tests/coverage_tests.pony - Split long lines, fixed indentation, reformatted XML test data
• libxml2/_tests/error_tests.pony - Split long commented line
• libxml2/_tests/xpath.pony - Fixed function call formatting, split long lines

Key Style Guide Rules Applied:

1. 80-column line length - All lines now fit within 80 characters
2. Multiline function parameters - Each parameter on separate line, return type with : on own line, => on separate line
3. Match expressions - Case pipes NOT indented, aligned with match keyword
4. No parentheses - Removed unnecessary parentheses around conditions in if and while
5. Proper indentation - 2 spaces, no tabs

All tests pass, confirming the formatting changes didn't break any functionality!
