From 90ad30e5b2a759333f06eee64e59a0d886d02036 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 10 Dec 2014 15:51:59 -0800 Subject: [PATCH] checkpatch: add test for consecutive string fragments Emit a warning when single line string coalescing occurs. Code that uses compiler string concatenation on a single line like: printk("foo" "bar"); is generally better to read concatenated like: printk("foobar"); Signed-off-by: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- scripts/checkpatch.pl | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl index d06b6be..5e63dce 100755 --- a/scripts/checkpatch.pl +++ b/scripts/checkpatch.pl @@ -4464,6 +4464,12 @@ sub process { "Concatenated strings should use spaces between elements\n" . $herecurr); } +# uncoalesced string fragments + if ($line =~ /"X*"\s*"/) { + WARN("STRING_FRAGMENTS", + "Consecutive strings are generally better as a single string\n" . $herecurr); + } + # warn about #if 0 if ($line =~ /^.\s*\#\s*if\s+0\b/) { CHK("REDUNDANT_CODE", -- 2.7.4
