Macro_Runner.java runMacroFromJar(String name) adds an extra "/" to the name, bug?

[Markus Sutter]

Hello everybody,
I want to load and run a macro file in my plugin. The macro file is
located in the same jar with the plugin, therefore I use Macro_Runner
to load and run it.
I specified the name of the macro file like "JAR:macros/macro.ijm",
but runMacroFromJar adds a / and so the macro is not found.
What's the correct way to load a macro from a jar or is this just a
bug in the method runMacroFromJar(String name) in class   Macro_Runner
on line 48:
InputStream is = pcl.getResourceAsStream("/" + name); may should look like
InputStream is = pcl.getResourceAsStream(name)

Kind regards
Markus

The JAR Resources Demo plugin at

  http://rsb.info.nih.gov/ij/plugins/pcl-demo.html

demonstrates how to load and run a macro from a JAR file.

Hi,
thx for your hint. I checked this demo already, but I thought there must be a simpler solution then loading the macro manually to a String and pass it do runMacro. Hence I looked into the IJ sources and found ij.plugin.Macro_Runner, which offers exactly that what I was looking for with the method runMacroFromJar(String name). But then I bumped into the problem with the extra "/".
Which I think is just a bug in the method runMacroFromJar(String name) in class   Macro_Runner
on line 48:
InputStream is = pcl.getResourceAsStream("/" + name); may should look like
InputStream is = pcl.getResourceAsStream(name)

(note: there is also the confusing ij.macro.MacroRunner)

I hope I could clarify a bit and I don't have to copy this getText method from the JAR Resources Demo.
Kind regards
Markus

The ImageJ 1.44e daily build adds the static method

        Macro_Runner.runMacroFromJar(String name, String arg)

for running a macro contained in a JAR file. This method does not add an extra "/" to the name and it allows you to pass an argument to the macro. Here is an example call:

   Macro_Runner.runMacroFromJar("macro.txt", "argument")
