Did you ever remember that you coded something exactly the way you need it now but don’t know the project name anymore? – Was it this one? (check out project, click through the files) No… wait, perhaps this one? (check out project, click through the files) No… *sigh*
At least for Subversion users the following script is a solution – you can narrow your search by regex concerning file path and content, but then search in all projects of the whole repository. Have fun with it!
#!/bin/sh
#
# svn-grep.sh <CONTENT_SEARCH_EXPRESSION> [<PATH_SEARCH_EXPRESSION>]
# - both arguments are regular expressions for egrep
# - the second argument is optional
# - branches and tags excluded, only searches in trunk
#
# example: ./svn-grep.sh "sun\.misc\.Unsafe" "\.java\$"
#
if [ "x$1" == "x" ]; then
echo "no content search expression - cancelled"
exit 1
fi
# local access is much faster, so use it if you can:
BASEURL="file:///opt/svn-repo/projects"
#BASEURL="https://svn.mydomain.com/projects"
SEARCH=$1
NAMEEXCLUDE="\(/tags/\|/branches/\|/\$\)"
NAMESEARCH='.'
if [ "x$2" != "x" ]; then
NAMESEARCH="$2"
fi
echo ""
echo "starting a search in $BASEURL for $SEARCH in files with a path like $NAMESEARCH"
echo ""
echo "step 1/2: collecting all paths to be considered (can take some time)..."
TEMPFILE=$(mktemp /tmp/svn-grep.XXXXXXXXXX)
svn ls -R "$BASEURL" | grep -v -e "$NAMEEXCLUDE" | grep -e "$NAMESEARCH" >$TEMPFILE &
SVN_LS_PID=$!
while ps -p $SVN_LS_PID >/dev/null; do
sleep 1
TEMPFILE_LINES=$(cat $TEMPFILE | wc -l)
echo -ne "\r [ found $TEMPFILE_LINES candidates ] "
done
TEMPFILE_LINES=$(cat $TEMPFILE | wc -l)
echo -e "\rstep 1/2 finished, found $TEMPFILE_LINES candidates"
echo ""
echo "step 2/2: search through the contents of all candidates"
