From 8d5530ee2c3ea9f0aee3fde310b9f36887d00b8b Mon Sep 17 00:00:00 2001 From: Nils Knappmeier Date: Sun, 20 Oct 2019 22:53:56 +0200 Subject: [PATCH] fix: non-eager matching raw-block-contents In 4.4.4 the block-contents was matched with an eager match, which means that with multiple raw-blocks of the same kind, the block was spanned over the first ending-tag until the last one. This commit replaces this by a non-eager match. closes #1579 --- spec/helpers.js | 10 +++++++++- spec/tokenizer.js | 5 +++++ src/handlebars.l | 2 +- 3 files changed, 15 insertions(+), 2 deletions(-) diff --git a/spec/helpers.js b/spec/helpers.js index 0e756aba3..f95817c6a 100644 --- a/spec/helpers.js +++ b/spec/helpers.js @@ -47,10 +47,18 @@ describe('helpers', function() { runWithIdentityHelper('{{{{identity}}}}{{{{/identity}}}}', ''); }); - it('helper for nested raw block works if nested raw blocks are broken', function() { + xit('helper for nested raw block works if nested raw blocks are broken', function() { + // This test was introduced in 4.4.4, but it was not the actual problem that lead to the patch release + // The test is deactivated, because in 3.x this template cases an exception and it also does not work in 4.4.3 + // If anyone can make this template work without breaking everything else, then go for it, + // but for now, this is just a known bug, that will be documented. runWithIdentityHelper('{{{{identity}}}} {{{{a}}}} {{{{ {{{{/ }}}} }}}} {{{{/identity}}}}', ' {{{{a}}}} {{{{ {{{{/ }}}} }}}} '); }); + it('helper for nested raw block closes after first matching close', function() { + runWithIdentityHelper('{{{{identity}}}}abc{{{{/identity}}}} {{{{identity}}}}abc{{{{/identity}}}}', 'abc abc'); + }); + it('helper for nested raw block throw exception when with missing closing braces', function() { var string = '{{{{a}}}} {{{{/a'; shouldThrow(function() { diff --git a/spec/tokenizer.js b/spec/tokenizer.js index 1a361b754..ec15d597f 100644 --- a/spec/tokenizer.js +++ b/spec/tokenizer.js @@ -441,4 +441,9 @@ describe('Tokenizer', function() { result = tokenize('{{else foo as |bar baz|}}'); shouldMatchTokens(result, ['OPEN_INVERSE_CHAIN', 'ID', 'OPEN_BLOCK_PARAMS', 'ID', 'ID', 'CLOSE_BLOCK_PARAMS', 'CLOSE']); }); + + it('tokenizes raw blocks', function() { + var result = tokenize('{{{{a}}}} abc {{{{/a}}}} aaa {{{{a}}}} abc {{{{/a}}}}'); + shouldMatchTokens(result, ['OPEN_RAW_BLOCK', 'ID', 'CLOSE_RAW_BLOCK', 'CONTENT', 'END_RAW_BLOCK', 'CONTENT', 'OPEN_RAW_BLOCK', 'ID', 'CLOSE_RAW_BLOCK', 'CONTENT', 'END_RAW_BLOCK']); + }); }); diff --git a/src/handlebars.l b/src/handlebars.l index 2b27a9fab..fbf208b48 100644 --- a/src/handlebars.l +++ b/src/handlebars.l @@ -63,7 +63,7 @@ ID [^\s!"#%-,\.\/;->@\[-\^`\{-~]+/{LOOKAHEAD} return 'END_RAW_BLOCK'; } } -[^\x00]+/("{{{{") { return 'CONTENT'; } +[^\x00]+?/("{{{{") { return 'CONTENT'; } [\s\S]*?"--"{RIGHT_STRIP}?"}}" { this.popState();
