Path functions available to Jelly script?

I'd like to be able to do things like separate the directory and file name from a full path in Hudson/Jenkins's jelly script.

For example if I have /dir1/dir2/dir3/file.ext I'd like to (in jelly script) get access to /dir1/dir2/dir3 and file.ext.

Are the java io functions like getPath() and getName() available to jelly script?

Solution

  • Dion Gillard's Jelly: Executable XML deck was really helpful in sorting this out. From the slides I learned about the invoke (and invokeStatic) tags which were exactly what I needed. The Apache FilenameUtils class has some very nice static methods for dealing with filenames and it's included with Hudson. 

    <j:jelly xmlns:j="jelly:core">
  <j:set var="fullpath" value="/dir1/dir2/dir3/file.ext"/>

  <!-- get the path without the filename -->
  <j:invokeStatic var="justpath" method="getPath" className="org.apache.commons.io.FilenameUtils">
    <j:arg value="${fullpath}"/>
  </j:invokeStatic>

  <!-- get just the filename -->
  <j:invokeStatic var="justname" method="getName" className="org.apache.commons.io.FilenameUtils">
    <j:arg value="${fullpath}"/>
  </j:invokeStatic>
</j:jelly>

    In the example above, justpath will be set to /dir1/dir2/dir3/ and justname will be set to file.ext.
