From 16c954898f62559724690f3fd61280773276d3d1 Mon Sep 17 00:00:00 2001 From: semihalev Date: Tue, 11 Mar 2025 13:15:07 +0300 Subject: [PATCH] Fix macro functionality and add comprehensive tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fixed macro parameter parsing with improved tokenization handling - Added support for proper module.function() syntax in templates - Enhanced filter handling within macro variables - Added support for variable interpolation in macro body - Added comprehensive test suite for macros with various scenarios - Improved overall coverage from 43.8% to 45.7% 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- advanced_filters_test.go | 2 +- control_structures_test.go | 4 +- debugging_test.go | 10 +- direct_negative_test.go | 2 +- expr.go | 10 +- extension.go | 24 +-- extensions_test.go | 1 -
