Hi,
I'm trying to do some Lua scripting, and I run into a problem that I
do not understand. Install this simple script, and bind the provided
funtion "foo" to a shortcut button.
local dt = require "darktable"
local function foo()
print("________________________________________")
print("--- action images ---")
for _, i in pairs(dt.gui.action_images) do
print(i.id, i)
end
print("--- collection ---")
for _, i in pairs(dt.collection) do
print(i.id, i)
end
end
dt.register_event("shortcut", function(_, _) foo() end, "foo")
When the function is invoked, it should print the image IDs of all
images in the collection, and also the image IDs that would be
affected by actions like, eg., color labeling.
Take two images that are not next to each other, and give them a
unique color label. Limit the collection to that.
Now invoking that function here always lists an image as part of the
collection that is not part of the collection! And one of the images
in the collection, clearly visible in lighttable, is not listed in the
collection.
Whassup?
Is there as seasoned Lua+DT hacker observing this?
I have verified this even on a pristine database on freshly imported
directory raws, without sidecars in that directory:
rm -rf /tmp/dtlib
rm -rf /tmp/dttest/*xmp
darktable --library /tmp/dtlib -d lua /tmp/dttest
By the way: Is there any good reason why `dt.gui.action_images` and
`dt.collection` do not return a table that maps the image id to the
image?
Thanks
Stefan
