Claude Brisson closed VELOCITY-787. ----------------------------------- Resolution: Won't Fix To summerize Nathan and Christoph comments: outside the scope of Velocity. I agree. > Write to multiple files, controlled by template directives > ---------------------------------------------------------- > > Key: VELOCITY-787 > URL: https://issues.apache.org/jira/browse/VELOCITY-787 > Project: Velocity > Issue Type: New Feature > Components: Engine > Affects Versions: 2.x > Environment: All environments > Reporter: Don Mendelson > Attachments: FileTool.java > > > For some purposes, such as code generation, it would be very desirable to > output to multiple files from the same context. For example, to generate code > for a C++ class, two files must be generated - a header and implementation > file. Rendering could be driven by the same context in both cases, which > would desribe the class name, method signatures, etc. Currently this must be > done by running the engine twice - once with a header template and again with > an implementation file template. > Furthermore, it would desirable to determine the output file names during > rendering, based on a combination of template directives and data in the > context. To use the code generation example, the header and implementation > file names would be determined by the name of the class to be generated. > This is not possible with the current method signature of Directive: > public boolean render(InternalContextAdapter context, Writer writer, Node > node) > An output directive would want to change the writer to a different instance > of FileWriter, for instance. But since Java passes object references by > value, the writer object cannot be replaced. > The proposal is to provide a method to install a new instance of Writer > during rendering of a template. This would support both writing multiple > outputs in one run of the engine as well as controlling the file names of the > outputs. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@velocity.apache.org For additional commands, e-mail: dev-h...@velocity.apache.org
