2.1.0 Uncontrolled Space

Added

• parseWithoutProcessing() method.

Changed

• Optimized whitespace control and lexer position advancement.
• Removed underscore from PathExpression::this_ to align with the Handlebars.js AST.

Fixed

• Close tag indentation wasn't consistently stripped from chained {{else if}} branches of a standalone block.
• Tilde whitespace control in one {{~else if}} branch unexpectedly leaked onto unrelated branches.

Both of the above issues stemmed from bugs in the Handlebars.js parser, and I opened PR handlebars-lang/handlebars-parser#31 to also fix them there.

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 Zero Head

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 Root SubExpression

Fixed

• Parsing of SubExpressions that are PathExpression roots.

1.1.0 Optimal 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 Initial Release

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