Should that not be macros/FunctionLibrary.txt?

Not according to the manual. The ImageJ Macro Language Programmer’s Reference Guide v1.46d states on page 16:

"However, those functions that you want to be available from all macros can be included in special macro that is appended to any executed macro. This special macro must be available from the following location: ImageJ/macros/Library.txt .

In short, the ImageJ/macros/Library.txt macro is appended to any executed or installed macro."


I have reported this first on the ImageJ mailing list

http://imagej.1557.n6.nabble.com/Library-txt-is-not-being-loaded-td4999246.html

and was told the same. At the time I tried to use that name but didn't fix it.

Hi

I can confirm that this bug is exclusive to FIJI. I have just download ImageJ on its own (1.47d), and Library.txt is loaded just fine. On this version of ImageJ I tried to rename Library.txt to FunctionLibrary.txt which made it fail so indeed Library.txt is the right name.

I have also tried to use FIJI with ImageJ 1.47d (not ImageJA) but that also does not fix the bug. This further suggests that the bug is somewhere in the FIJI project.

This bug severely limits the usefulness of macro scripting.  

I am certain that being able to maintain a reusable set of macro functions would make life a lot easy for many users.

I cannot reproduce this problem with an up-to-date Fiji on OS X 10.10.

I created the file /Applications/Fiji.app/macros/Library.txt and put the following contents:

 function hello() {
   showMessage("Hello world", "How's it going today?");
 }

I then started Fiji, pressed [ for the Script Editor, changed the Language to IJ1 Macro, and typed the following macro:

 hello();

Pressed Cmd+R to run, and it displayed the dialog as desired.

Can you please provide a more specific recipe to reproduce?

Hi Curtis,

thanks for the quick the reply.

After playing around I think the problem is that I need to update the loaded macros after any changes are made to the Library.txt file.  I’ve found that “Help > Refresh Menus” does the trick.  

It seems that this can't be called from a macro, probably for good reasons.  Is there way to avoid manual refreshing?  

What I want to do is for my macro to update the helper functions by cat’ing all the *.ijm files some directory to Library.txt, refresh the macro list, then be able to user the function from Library.txt.  

Thanks,

Chris

I am closing this bug, since the description is "Library.txt is not being loaded" and it seems that it is now, in fact, being loaded as expected. A step forward. ;-)

Well, I think it can be called from a macro. It just shows that popup dialog box now. We added that on purpose so that people are aware that "Refresh Menus" doesn't do a complete job of actually refreshing the menus anymore. But perhaps we should not show that message in macro mode...

I'd like to understand your use case. Do you require this sort of dynamic updating without restarting ImageJ? Or would it be enough for your Library.txt to use a trick similar to:

https://github.com/fiji/fiji/blob/86622adda86e786dac01e8f7339cba5cb772b50b/macros/StartupMacros.fiji.ijm#L49-L60

?

Yes, I confirm I can no longer reproduce this bug with latest update of FIJI. Thank you
