Hi all,
I wrote the following script based on checkpatch.pl:
find . -name '*.c' |xargs ../../scripts/checkpatch.pl --file |grep -B
1 ^total | awk '/^total/{ errors+=$2; warnings+=$4; lines+=$6; } {
print } END {print ""; print "--- Report ---";print "number of files
"(NR+1)/3; print "number of errors: "errors; print "number of
warnings: "warnings; print "number of lines: "lines; print "% errors:
"errors/lines*100;print "% warning: "warnings/lines*100;}'
For example, I run it in the /arch/x86/ dir in the mm branch of the
x86 git tree.
What I got is the following:
...
...
...
...
./xen/mmu.c
total: 0 errors, 0 warnings, 644 lines checked
--
./xen/multicalls.c
total: 2 errors, 2 warnings, 138 lines checked
--
./xen/setup.c
total: 0 errors, 7 warnings, 110 lines checked
--
./xen/smp.c
total: 1 errors, 1 warnings, 421 lines checked
--
./xen/time.c
total: 3 errors, 3 warnings, 599 lines checked
--- Report ---
number of files 314
number of errors: 3498
number of warnings: 2421
number of lines: 115226
% errors: 3.03577
% warning: 2.10109
This is after applying the following patch to checkpatch.pl (probabily
wordwrapped, but that's just to give you an idea):
diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl
index 579f50f..079c73c 100755
--- a/scripts/checkpatch.pl
+++ b/scripts/checkpatch.pl
@@ -1580,6 +1580,7 @@ sub process {

if ($summary) {
+ print "$filename \n";
print "total: $cnt_error errors, $cnt_warn warnings, " .
(($check)? "$cnt_chk checks, " : "") .
"$cnt_lines lines checked\n";
Does anybody have an idea on how to get the 10 most offenders file
from the output of my script?
Thanks.
Ciao,
