Fun late last night, script to add subversion ignores
 (incrementally and using wildcards for dotted extensions).
Script should be run on clean repository after build e.g. by a automated buildbot.
Note the bash propadd function. Would be nice if subversion provided that.

#!/bin/bash

# e.g. propadd svn:ignore . "*.a"
# e.g. (multiline) propadd svn:ignore . "*.a
# *.o"
propadd () {
  PROP=$1
  FILE=$2
  ADDVAL=$3
  OLDVAL=`svn propget $PROP $FILE`
  NEWVAL="$OLDVAL
$ADDVAL"
  echo svn propset $PROP \""$NEWVAL"\" $FILE
  svn propset $PROP "$NEWVAL" $FILE
}

#####
# get plain list of files
svn status -u |grep ^? |sed "s/\?  *//" >svn_ignore_files.log

##### Anything with a dotted extension insert wildcard * in place of rest of file name
# sort | uniq to rm duplicates for wildcards
IGNORES=`cat svn_ignore_files.log |sed "s/\([^\/][^\/]*\)\.\([^\.\/]*\)$/\*\.\2/" |sed s/^/BBB/ |sort |uniq`

### for or echo in shell expand <dir>/*.ext to full list of matches
### so add BBB
### meh

##### for each dir/file call propadd svn:ignore
# watch out $fNAME can have wildcard
for f in $IGNORES ; do
    #echo "f=$f" ;
    fNAME=${f##*\/}
    fNAME=${fNAME##BBB}
    fPATH=${f%%"$fNAME"}
    fPATH=${fPATH##BBB}
    if [[ "$fPATH" == "" ]] ; then fPATH=.; fi
    #echo fNAME=$fNAME fPATH=$fPATH
    #ls $fPATH/$fNAME
    propadd svn:ignore $fPATH "$fNAME"
done

echo "Now commit ignores: 'svn ci -m\"updated svn:ignore values\"'"
echo "Or remove unwanted ignores 'svn revert [-R] <dir>'"
echo "'svn status' will show
