v0.1.4

Enum Format Specifier Support

• Added TryFormatEnum / TryFormatEnumUnderlying in _XS handler
• D, d: formats enum as decimal numeric value via Unsafe.As<T, underlying> — zero boxing
• X, x: formats enum as hex with zero-padded digits matching underlying type size (e.g. int → X8)
• G, F, and other specifiers: fallback to IFormattable.ToString (boxes)
• Previously all enum format specifiers were ignored (ZString EnumUtil<T> limitation)

SetTextX Extension Method for TMP_Text

• TMP_Text.SetTextX($"...") sets interpolated string to TextMeshPro with zero string allocation
• Passes internal char[] buffer directly via SetCharArray (bypasses ToString())
• Benchmark: GC 5 (TMP internal only) vs GC 12 (tmp.text = $"...")

v0.1.3

Bug Fixes

Fix retry buffer size calculation in AppendFormatInternal

• Changed retry buffer from written > buf.Length ? written : buf.Length * 2 to buf.Length * 2
• written is unreliable on TryFormat failure (may be 0 or partial), so always double the buffer

Improvements

Add diagnostic info to FormatException

• FormatException message now includes Type, alignment, format for easier debugging

v0.1.2

Performance Improvements

Replace Composite Format with Direct TryFormatDelegate

• Removed AppendFormattedViaComposite, replaced with AppendFormatInternal
• Before: built composite format string ("{0,alignment:format}") on the stack per call, then re-parsed via _sb.AppendFormat
• After: calls FormatterCache<T>.TryFormatDelegate directly and handles alignment padding inline
• Eliminates composite string construction and re-parsing overhead

Avoid Boxing on Null Check (Debug build only)

• Changed null check from value == null to default(T) == null && value == null
• Prevents unnecessary boxing for value types (null branch entered only for reference types / Nullable)

Tests

Benchmark Test Improvements

• StringBuilder_FourArgs: changed from reusing StringBuilder to creating a new instance per iteration (fair comparison)
• StringBuilder128_FourArgs: added benchmark that creates a new StringBuilder with initial capacity 128 per iteration
• StringBuilderShare_FourArgs: separated the existing shared-StringBuilder approach into its own benchmark

v0.1.1

New Features

Format Parameter Support

Alignment and format specifiers are now properly supported.

• Fixed: Alignment and format parameters were previously ignored
• Example: XString.Format($"Score: {score,10:F2}") aligns to 10 characters with 2 decimal places

Support for Up to 16 Format Arguments

Format overloads extended from T1T4 to T1T16.

• Example: XString.Format("{0} {1} ... {15}", arg1, arg2, ..., arg16)

Tests

Expanded from 34 to 93 (+174%)

Added tests:

• 4 concurrency tests (multithreading safety)
• 11 edge case tests (boundary conditions, large strings)
• 33 functional tests (various scenarios)
