## Name
|
|
|
|
|
|
|
|
|
|
multi_os.lua - an example script that runs on linux, MacOS, and Windows.
|
|
|
|
|
|
|
|
|
|
## Description
|
|
|
|
|
|
|
|
|
|
multi_os is an example of how to write a script that will run on different
|
|
|
|
|
operating systems. It uses the lua-scripts libraries to lessen the amount
|
|
|
|
|
of code that needs to be written, as well as gaining access to tested
|
|
|
|
|
cross-platform routines. This script also performs a function that some
|
|
|
|
|
may find useful. It creates a button in the lighttable selected images module
|
|
|
|
|
that extracts the embedded jpeg image from a raw file, then imports it and groups
|
|
|
|
|
it with the raw file. A keyboard shortcut is also created. A key combination can
|
|
|
|
|
be assigned to the shortcut in the lua preferences and then the action can be invoked
|
|
|
|
|
by hovering over the image and pressing the key combination.
