In GIMP 2.10.18 - after creating a text layer, I edit the layer attributes to give the text layer a meaningful name. This is important as I'm working with a python script that will reference the layer names.
However, when I modify the text - it changes the name of the layer too! This means that the script that automatically changes the contents of the text will inadvertently change the name of the layer as well, breaking the script!
Is there any way to turn this feature off?
Not as far as I know. There are however several workarounds:
If you have only one set of layers to process, you can set the "chainlink" indicator (and retrieve it with layer.linked or the PDB equivalent).
If you need to distinguish several sets of layers there are several possibilities:
Put the layers in layer groups (one for each processing) and iterate the children of each group.
Set different color tags on the layers (this can be retrieved with pdb.gimp_item_get_color_tag(item)). The good side of the technique is that color tags can be set (and checked) with the UI, and won't have side effects like groups.
Parasite are named values that you can add to Gimp items. You can attach parasite to layers:
# attach:
parasite=gimp.Parasite('<name>','<value>)
layer.parasite_attach(parasite)
# retrieve:
parasite=layer.parasite_find('<name>')
value=parasite.data
# remove:
layer.parasite_detach('<name>')
This would require a side script (for instance, one that copies the initial layer names to parasites) but the processing becomes completely independent from the name.
