Concatenate a layer name with fixed text and variables

[tkemmere]

Thank you Offnuts!

More complex than I expected, but...
...I understand why that is so, cause this way offers much versatility
...well explained by you!

I got it going almost immediately! 

Code:

...
[
    (PF_SLIDER, "contrast", "Contrast", 0, (0, 0.5, 0.01)),
    (PF_SLIDER, "blur", "Blur", 0, (0, 99, 1)),
]
...

pdb.gimp_item_set_name(new_layer, "Blur %2d, contrast %4.2f" % (blur,contrast))

Thanks again!
