darktable-cli is useful to apply darktable crafted styles with the cli
Apparently it is not working in the darktable snap installation:
13:28 $ /snap/darktable/82/usr/bin/darktable-cli --help
/snap/darktable/82/usr/bin/darktable-cli: error while loading shared libraries: libOpenEXR-3_1.so.30: cannot open shared object file: No such file or directory
You cannot access a snap package’s executable files in this manner. They need to be exposed via /snap/bin/* by including a definition when building the snap. This snap does not include such a definition for the darktable-cli executable. It needs adding for people to be able to use it. The repository is at https://github.com/sergiusens/darktable-snap, maintained by @sergiusens.
I might have some time to add this via a PR, so that future revisions of the snap include the access, but can’t guarantee that I will.
