From 5d6b4ef73f1d9532fe3f16cdbf5994aa6a3eb9fe Mon Sep 17 00:00:00 2001 From: Johannes Wienke Date: Wed, 7 Nov 2018 13:25:48 +0100 Subject: [PATCH 1/2] Support older checkstyle versions The output format used by older checkstyle versions differs from the one of new versions. This commit adds a second parsing iteration on the output lines with a suitable pattern to support both versions in parallel. Due to the differences in the order of matching groups this is hard to achieve in a single pass through the output lines. An appropriate test case is added. --- ale_linters/java/checkstyle.vim | 15 ++++++++++++++- test/handler/test_checkstyle_handler.vader | 13 +++++++++++++ 2 files changed, 27 insertions(+), 1 deletion(-) diff --git a/ale_linters/java/checkstyle.vim b/ale_linters/java/checkstyle.vim index 8155170a..7d0c31ba 100644 --- a/ale_linters/java/checkstyle.vim +++ b/ale_linters/java/checkstyle.vim @@ -2,9 +2,11 @@ " Description: checkstyle for Java files function! ale_linters#java#checkstyle#Handle(buffer, lines) abort - let l:pattern = '\v\[(WARN|ERROR)\] [a-zA-Z]?:?[^:]+:(\d+):(\d+)?:?
