PHP, SVN: Watch a Subversion repo and automatically update the working copy when changes are committed. An old, old hack that fulfilled a need at one time. Clever, but I could do better now. SMDH

svnup.sh

#!/bin/sh --

# While working with PHP applications, there were a few obstacles to
# local development.  It wasn't possible/easy to get an Oracle server
# or Oracle client for PHP to run under Mac OS X.  Furthermore, the
# local environment didn't have the authenticated user's name available
# in the environment.  Although an odd situation, it was easier to
# develop on the local machine, commit to SVN, then update a copy of
# the project running on a server that supported Oracle, CoSign, etc.
# The following script, run in the project directory of the server
# with the project checked out using a "file:///" URL, would check
# the repository for updates once every second, apply them, and update
# the version.txt file with the current SVN version and time:

sleepTime='0.25s'
tempfile="/tmp/svnup.$$"

echo 'svn continuous update'
echo "Starting with revision `svnversion`."
echo "`svnversion` on `date '+%F %T'`" > version.txt

while [ 1 ]; do
    svn up > $tempfile
    numupdates=`wc -l < $tempfile`

    if [ "$numupdates" -ne "1" ]; then
        tput bel
        cat $tempfile
        date '+%F %T'
        echo "`svnversion` on `date '+%F %T'`" > version.txt
    fi

    printf -- '/\r'
    sleep $sleepTime
    printf -- '-\r'
    sleep $sleepTime
    printf -- '\\\r'
    sleep $sleepTime
    printf -- '|\r'
    sleep $sleepTime
done
