v1.8.1

Performance

• Template Rendering: ~25% faster, ~54% less memory, ~27% fewer allocations in template rendering benchmarks.
  • Cache compiled scanner regex instead of recompiling per Scan() call
  • Reuse forloop variable map across loop iterations instead of allocating a new map per iteration
  • Add fast paths for string, int, float64, and bool in writeObject, avoiding fmt.Sprint and reflection
  • Reuse expression evaluation context across {{ }} expressions instead of allocating per expression
  • Use stack-allocated array for filter arguments, avoiding heap allocation for filters with ≤4 args
  • Use maps.Copy with pre-sized maps for bindings copies

Fixed

• String-to-Number Conversion in Arithmetic Filters: Fixed regression where string values from bindings were not converted to numbers in plus, minus, times, and divided_by filters. For example, {{ str_var | plus: 1 }} where str_var = "10" now correctly returns 11 instead of 1. This was introduced in v1.8.0 when filter signatures changed from float64 to any (#124).

Changed

• Replace custom intMin/intMax helpers with Go 1.21+ min/max builtins.

Tests

• Expanded test coverage across render, parser, values, filters, and engine packages.
