Copy all svn:* properties from one file to another

pvdb (Peter Vandenberk) — Fri, 16 May 2008 11:25:10 GMT

The following script can be used to copy all SVN properties from one file (presumably a file that's already under SVN control) to another file (which you presumably want to put under SVN control, and which you want to check in with the same SVN properties).



#!/bin/sh



ORIG=$1 ; shift ;

[ -e "$ORIG" ] || exit ;



for PROP in `svn pl "$ORIG" | sed -n '2,$p'` ; do

        VALUE=`svn pg $PROP "$ORIG"` ;

        for FILE ; do

                [ -e "$FILE" ] && svn ps $PROP "$VALUE" "$FILE" ;

        done

done



# That's it, Folks!

If you put the above code in a shell script called...



svnprops.sh

... then you can run it as follows if you want to copy all svn:* properties FROM original.file TO blegga:



pvdb@localhost ~ $ ./svnprops.sh original.file blegga 

property 'svn:mime-type' set on 'blegga'

property 'svn:eol-style' set on 'blegga'

pvdb@localhost ~ $ _

... or as follows for multiple target files:



pvdb@localhost ~ $ ./svnprops.sh another.original.file blegga foo bar 

property 'svn:mime-type' set on 'blegga'

property 'svn:mime-type' set on 'foo'

property 'svn:mime-type' set on 'bar'

pvdb@localhost ~ $ _

Loading a property file from the classpath

Loads a property file located anywhere in the classpath



    private Properties getPropertiesFromClasspath(String propFileName) throws IOException {

        // loading xmlProfileGen.properties from the classpath

        Properties props = new Properties();

        InputStream inputStream = this.getClass().getClassLoader()

            .getResourceAsStream(propFileName);



        if (inputStream == null) {

            throw new FileNotFoundException("property file '" + propFileName

                + "' not found in the classpath");

        }



        props.load(inputStream);



        return props;

    }

Loading an xml properties file

// simple example of loading an xml file into Properties.



Properties properties = new Properties();

try {

    InputStream xmlStream = getClass().getResourceAsStream("properties.xml");

    if( xmlStream == null ) {

         //throw some error

    }            

    properties.loadFromXML(xmlStream);

} catch (IOException exception) {

    // throw exception

}

Change Text Properties on Mouseover

This only works with the IE browsers. Add this code within your tags. To keep the underline on your links, replace "none" with "underline" Change "YourColor" with the hexidecimal number of color required.
