Simple code analyzer, using PMD and Zenity for a little gui. I'm using it with Vim but outputs to file so compatible with any tool

analyze-pmd.sh

#!/bin/sh

TITLE="Analyze the code"
TEXT="Choose your rules (can be multiple)"
FILENAME=/tmp/pmd-$(date "+%F-%H-%M").log

declare -a RULES=("android"
	"basic"
	"braces"
	"codesize"
	"design"
	"finalizers"
	"imports"
	"junit"
	"logging-java"
	"naming"
	"optimizations"
	"strictexception"
	"typeresolution"
	"unusedcode")

SEL_RULES=$(zenity --list --multiple --title="$TITLE" --text="$TEXT" --width=640 --height=640 --column=Rules ${RULES[@]} 2>/dev/null)

IFS='|' read -r -a rules <<<$(echo $SEL_RULES)

if [ ! -z $1 ]; then
	DIR=$1
else
	DIR=$(pwd)
fi
while test "$DIR" != "/"; do
	for m in GNUmakefile makefile Makefile gradlew Gradle; do

			done
			echo "$FILENAME"
			cat $FILENAME
			exit 0

	done
	DIR=$(dirname "${DIR}")
done

exit 0
