2.0.0 - Stateless Parser

Changed

• Moved the optional ignoreStandalone parameter from ParserFactory::create() to the Parser::parse() method. This makes the parser instance independent of options so it can be reused when compiling multiple templates, enabling better performance and lower memory usage.

1.1.2

Fixed

• Parsing of 0 as path expression head (devtheorem/php-handlebars#16).

Changed

• Optimized parser slightly by replacing a few unnecessary preg_match calls.

1.1.1

Fixed

• Parsing of SubExpressions that are PathExpression roots.

1.1.0 - 30x faster lexer

This release will be the foundation for PHP Handlebars 1.0.

Changed

• Optimized position tracking to avoid per-token full-text rescans.
• Made use of the preg_match() offset parameter and \G anchor to avoid per-token string allocations.
• Combined alternation pattern per state: replaced N separate preg_match() calls (one per rule) with a single call against a per-state /\G(?:(rule0)|(rule1)|...)/ pattern, letting PCRE try all alternatives in one pass.

Added

• Benchmark to test parsing a large, complex template 1000 times.

In this release, parsing a complex, 13 KB Handlebars template is now about 30x faster than in v1.0.0.

1.0.0

The full Handlebars.js grammar, whitespace control, and parse error handling is now implemented in native PHP.
