runtime(yaml): improve syntax highlighting for YAML Commit: https://github.com/vim/vim/commit/cc7597c1edf478ad912d45b27f17175236f9791e Author: itchyny <itchyny@cybozu.co.jp> Date: Mon Apr 1 14:54:36 2024 +0200 runtime(yaml): improve syntax highlighting for YAML - Recognize block scalar style to avoid unexpected highlighting by `yamlFlowString` (fix https://github.com/vim/vim/issues/11517) - Improve performance of `yamlFlowMappingKey` by allowing execution by the NFA engine (fix https://github.com/vim/vim/issues/10730) - It was intentionally disabled before patterns were optimized by `s:SimplifyToAssumeAllPrintable`. - Fix detection of flow style mapping indicators (fix #8234). - Enable highlighting of explicit mapping value indicators and node properties in flow style. - Add syntax highlighting tests closes: #14354 Signed-off-by: itchyny <itchyny@cybozu.co.jp> Signed-off-by: Christian Brabandt <cb@256bit.org>
