From 108d2bf74bc02eaed74beae5589d7116936aefa5 Mon Sep 17 00:00:00 2001 From: Christian Clason Date: Thu, 25 Jul 2024 09:26:13 +0200 Subject: [PATCH] vim-patch:e73e5b8: runtime(java): Optionally highlight the :: token for method references This token will be highlighted, similar to the arrow of lambda expressions, whenever "g:java_highlight_functions" is defined. Also: - Improve the recognition of _switch-case_ labels (D-Cysteine). - Remove insignificant empty statements in syntax test files. closes: vim/vim#15322 References: https://docs.oracle.com/javase/specs/jls/se21/html/jls-15.html#jls-15.13 https://github.com/fleiner/vim/pull/1 https://github.com/vim/vim/commit/e73e5b889b52675a9ea58cf154235c7f25d107d5 Co-authored-by: Aliaksei Budavei <0x000c70@gmail.com> Co-authored-by: D-Cysteine <54219287+D-Cysteine@users.noreply.github.com> --- runtime/doc/syntax.txt | 16 +++++++++------- runtime/syntax/java.vim | 10 +++++++--- 2 files changed, 16 insertions(+), 10 deletions(-) diff --git a/runtime/doc/syntax.txt b/runtime/doc/syntax.txt index 4d301bcb80..f7a8940a52 100644 --- a/runtime/doc/syntax.txt +++ b/runtime/doc/syntax.txt @@ -1574,11 +1574,11 @@ use the following: > :let java_highlight_java_io=1 Check the javaid.vim file for a list of all the packages that are supported. -Function names are not highlighted, as the way to find functions depends on -how you write Java code.
