The packagers could enable the internal interpreter, or allow the package to link the interpreter from the operating system, or bundle a copy of lua with the package. If you use one of these packages and wish to use the lua scripts, please contact the package maintainer and suggest the above fixes.

 ## Enabling
 
 When darktable starts it looks for a file name `~/.config/darktable/luarc` (`%LOCALAPPDATA%\darktable\luarc` for windows) and reads it to see which scripts to include. The file is a plain text file with entries of the form `require "<directory>/<name>"` where directory is the directory containing the scripts, from the above list, and name is the name from the above list. To include GIMP the line would be `require "contrib/gimp"`.
 
+The recommended way to enable and disable specific scripts is using the script manager module.  To use script manager do the following:
+
+### Linux or MacOS
+
+    echo 'require "tools/script_manager"' > ~/.config/darktable/luarc
+
+### Windows
+
+    echo require "tools/script_manager" > %LOCALAPPDATA%\darktable\luarc

+### Flatpak

-This plugin adds the module "OpenInExplorer" to darktable's lighttable view
+This plugin adds the module "OpenInExplorer" to darktable's lighttable view.
 
 ----REQUIRED SOFTWARE----
-Microsoft Windows or Linux with installed Nautilus
+Apple macOS, Microsoft Windows or Linux
 
 ----USAGE----
 Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
- 1) Copy this file in to your "lua/contrib" folder where all other scripts reside. 
+ 1) Copy this file into your "lua/contrib" folder where all other scripts reside. 
  2) Require this file in your luarc file, as with any other dt plug-in
 
-Select the photo(s) you wish to find in explorer and press "Go to Folder". 
-A file explorer window will be opened for each selected file at the file's location; the file will be highlighted.
+Select the photo(s) you wish to find in your operating system's file manager and press "show in file explorer" in the "selected images" section.
+
+- Nautilus (Linux), Explorer (Windows), and Finder (macOS prior to Mojave) will open one window for each selected image at the file's location. The file name will be highlighted.
+
+- On macOS Mojave and Catalina the Finder will open one window for each different directory. In these windows only the last one of the corresponding files will be highlighted (bug or feature?).
+
+- Dolphin (Linux) will open one window with tabs for the different directories. All the selected images' file names are highlighted in their respective directories.
+
+As an alternative option you can choose to show the image file names as symbolic links in an arbitrary directory. Go to preferences|Lua options. This option is not available for Windows users as on Windows solely admins are allowed to create links.
+
+- Pros: You do not clutter up your display with multiple windows. So there is no need to limit the number of selections.
+
+- Cons: If you want to work with the files you are one step behind the original data.

+  DESCRIPTION
+    RL_out_sharp.lua - Richardson-Lucy output sharpening using GMic
+
+    This script provides a new target storage "RL output sharpen". 
+    Images exported will be sharpened using GMic (RL deblur algorithm)
+
+  REQUIRED SOFTWARE
+  GMic command line interface (CLI) https://gmic.eu/download.shtml
+    
+  USAGE
+    * require this script from main lua file
+    * in lua preferences, select the GMic cli executable
+    * from "export selected", choose "RL output sharpen"
+    * configure output folder 
+    * configure RL parameters with sliders
+    * configure temp files format and quality, jpg 8bpp (good quality) 
+      and tif 16bpp (best quality) are supported
+    * configure other export options (size, etc.)
+    * export, images will be first exported in the temp format, then sharpened
+    * sharpened images will be stored in jpg format in the output folder
+
+  EXAMPLE
+    set sigma = 0.7, iterations = 10, jpeg output quality = 95,
+    to correct blur due to image resize for web usage
+
+  CAVEATS
+    MAC compatibility not tested
+    Although Darktable can handle file names containing spaces, GMic cli cannot, 
+      so if you want to use this script please make sure that your images do not
+      have spaces in the file name and path
+  
+  BUGS, COMMENTS, SUGGESTIONS
+    send to Marco Carrarini, marco.carrarini@gmail.com

+    ext_editor.lua - edit images with external editors
+
+    This script provides helpers to edit image files with programs external to darktable. It adds:
+      - a new target storage "collection". Image exported will be reimported to collection for further edit with external programs
+      - a new module "external editors", visible in lightable and darkroom, to select a program from a list 
+      - of up to 9 external editors and run it on a selected image (adjust this limit by changing MAX_EDITORS)
+      - a set of lua preferences in order to configure name and path of up to 9 external editors
+      - a set of lua shortcuts in order to quick launch the external editors
+    
+  USAGE
+    * require this script from main lua file
+  
+    -- setup --
+      * in "preferences/lua options" configure name and path/command of external programs
+      * note that if a program name is left empty, that and all following entries will be ignored
+      * in "preferences/shortcuts/lua" configure shortcuts for external programs (optional)
+      * whenever programs preferences are changed, in external editors GUI, press "update list"
+
+    -- use --
+      * in the export dialog choose "collection" and select the format and bit depth for the
+        exported image
+      * press "export"
+      * the exported image will be imported into collection and grouped with the original image
+      
+      * in lighttable, select an image for editing with en external program 
+      * (or in darkroom for the image being edited):
+      * in external editors GUI, select program and press "edit"
+      * edit the image with the external editor, overwite the file, quit the external program
+      * the selected image will be updated
+      or
+      * in external editors GUI, select program and press "edit a copy"
+      * edit the image with the external editor, overwite the file, quit the external program
+      * a copy of the selected image will be created and updated
+      or
+      * use the shortcut to edit the current image with the corresponding external editor
+      * overwite the file, quit the external program
+      * the image will be updated
+    
+    * warning: mouseover on lighttable/filmstrip will prevail on current image
+    * this is the default DT behavior, not a bug of this script
+
+  CAVEATS
+    * MAC compatibility not tested
+  
+  BUGS, COMMENTS, SUGGESTIONS
+    * send to Marco Carrarini, marco.carrarini@gmail.com

+Multiple images for one face can exist, add a number to it, the
+number will be removed from the tag, for example:
+People|IknowYou1.jpg
+People|IknowYou2.jpg

+
+--[[About this Plugin
+Support for adjusting darktable exposure by Fujifilm raw exposure
+bias. This corrects for a DR100/DR200/DR400 "dynamic range" setting.
+
+Dependencies:
+- exiftool (https://www.sno.phy.queensu.ca/~phil/exiftool/)
+
+Based upon fujifilm_ratings by Ben Mendis
+
+The relevant tag is RawExposureBias (0x9650). This appears to
+represent the shift in EV for the chosen DR setting (whether manual or
+automatic). Note that even at 100DR ("standard") there is an EV shift:
+
+100 DR -> -0.72 EV
+200 DR -> -1.72 EV
+400 DR -> -2.72 EV
+
+The ideal would be to use exiv2 to read this tag, as this is the same
+code which darktable import uses. Unfortunately, exiv2 as of v0.27.3
+can't read this tag. As it is encoded as a 4-byte ratio of two signed
+shorts -- a novel data type -- it will require some attention to fix
+this.
+
+There is an exiv2-readable DevelopmentDynamicRange tag which maps to
+RawExposureBias as above.  DevelopmentDynamicRange is only present
+when tag DynamicRangeSetting (0x1402) is Manual/Raw (0x0001). When it
+is Auto (0x0000), the equivalent data is tag AutoDynamicRange
+(0x140b). But exiv2 currently can't read that tag either.
+
+Hence for now this code uses exiftool to read RawExposureBias, as a
+more general solution. As exiftool is approx. 10x slower than exiv2
+(Perl vs. C++), this may slow large imports.
+
+These tags have been checked on a Fujifilm X100S and X100V. Other
+cameras may behave in other ways.

+    image_time - non-destructively modify the image time
+
+    DESCRIPTION
+
+    image_time non destructively adjusts image times by modifying the 
+    database image exif_datetime_taken field.  There are 4 modes: adjust time,
+    set time, synchronize time, and reset time.
+
+      ADJUST TIME
+
+        adjust time mode lets you chose an offset in terms of years, months,
+        days, hours, minutes, and seconds.  The adjustment can be added or
+        subtracted.  
+
+        WARNING:  When adding and subtracting months the result will usually
+        be what is expected unless the time being adjusted is at the end of 
+        the month.  This is because a month is a variable amount of time that
+        can be 28, 29, 30 or 31 days depending on the month.  Example: It's 
+        March 31st and I subtract a month which not sets the time to February
+        31st.  When that gets set to a valid time, then the date changes to
+        March 3rd.
+
+      SET TIME
+
+        set time mode allows you to pick a date and time and set the image
+        time accordingly.  Fields may be left out.  This is useful when 
+        importing scanned images that don't have an embedded date.  
+
+      SYNCHRONIZE TIME
+
+        I recently purchased a 7DmkII to replace my aging 7D.  My 7D was still
+        serviceable, so I bought a remote control and figured I'd try shooting
+        events from 2 different perspectives.  I didn't think to synchonize the 
+        time between the 2 cameras, so when I loaded the images and sorted by
+        time it was a disaster.  I hacked a script together with hard coded values
+        to adjust the exif_datetime_taken value in the database for the 7D images 
+        so that everything sorted properly.  I've tried shooting with 2 cameras 
+        several times since that first attempt.  I've gotten better at getting the
+        camera times close, but still haven't managed to get them to sync.  So I
+        decided to think the problem through and write a proper script to take 
+        care of the problem.
+
+      RESET TIME
+
+        Select the images and click reset.  
+
+    USAGE
+
+      ADJUST TIME
+
+        Change the year, month, day, hour, minute, second dropdowns to the amount
+        of change desired.  Select add or subtract.  Select the images.  Click 
+        adjust.
+
+      SET TIME
+
+        Set the time fields to the desired time.  Select the images to change.  Click
+        set.
+
+      SYNCHRONIZE TIME
+
+        Select 2 images, one from each camera, of the same moment in time.  Click
+        the Calculate button to calculate the time difference.  The difference is
+        displayed in the difference entry.  You can manually adjust it by changing
+        the value if necessary.
+
+        Select the images that need their time adjusted.  Determine which way to adjust
+        adjust the time (add or subtract) and select the appropriate choice.
+
+        If the image times get messed up and you just want to start over, select reset time
+        from the mode and reset the image times.
+
+      RESET TIME
+
+        Select the images and click reset.

+  TRANSFER HIERARCHY
+  Allows the moving or copying of images from one directory
+  tree to another, while preserving the existing hierarchy.
+
+  AUTHOR
+  August Schwerdfeger (august@schwerdfeger.name)
+
+  ADDITIONAL SOFTWARE NEEDED FOR THIS SCRIPT
+  None.
+
+  USAGE
+  darktable's native operations for moving and copying images in
+  batches allow only one directory to be specified as the destination
+  for each batch. Those wanting to move or copy images from a _hierarchy_
+  of directories within darktable while preserving the directory structure,
+  must take the laborious step of performing the operation one individual
+  directory at a time.
+
+  This module allows the intact moving and copying of whole directory trees.
+  It was designed for the specific use case of rapidly transferring images
+  from a customary source (e.g., a staging directory on the local disk)
+  to a customary destination (e.g., a directory on a NAS device).
+
+  Instructions for operation:
+
+  1. Select the set of images you want to copy.
+
+  2. Click the "calculate" button. This will calculate the
+     lowest directory in the hierarchy that contains every selected
+     file (i.e., the common prefix of all the images' pathnames), and
+     write its path into the "existing root" text box.
+
+  3. If (a) you have specified the "customary source root" and "customary
+     destination root" preferences, and (b) the selected images are all
+     contained under the directory specified as the customary source
+     root, then the "root of destination" text box will also be
+     automatically filled out.
+
+     For example, suppose that you have specified '/home/user/Staging'
+     as your customary source root and '/mnt/storage' as your customary
+     destination root. If all selected images fell under the directory
+     '/home/user/Staging/2020/Roll0001', the "root of destination" would
+     be automatically filled out with '/mnt/storage/2020/Roll0001'.
+
+     But if all selected images fall under a directory outside the
+     specified customary source root (e.g., '/opt/other'), the "root
+     of destination" text box must be filled out manually.
+
+     It is also possible to edit the "root of destination" further once
+     it has been automatically filled out.
+
+  4. Click the "move" or "copy" button.
+
+     Before moving or copying any images, the module will first
+     replicate the necessary directory hierarchy by creating all
+     destination directories that do not already exist; should a
+     directory creation attempt fail, the operation will be
+     aborted, but any directories already created will not be
+     removed.
+
+     During the actual move/copy operation, the module transfers an
+     image by taking its path and replacing the string in the "existing
+     root" text box with that in the "root of destination" text box
+     (e.g., '/home/user/Staging/2020/Roll0001/DSC_0001.jpg' would be
+     transferred to '/mnt/storage/2020/Roll0001/DSC_0001.jpg').

+X-Touch Mini flexible encoder shortcuts
+
+This script will create virtual sliders that are mapped dynamically to
+the most relevant sliders for the currently focused processing module.
+Tailored modules are color zones, tone equalizer, color calibration and
+mask manager properties. The script can easily be amended for other
+devices or personal preferences. Virtual "toggle" buttons can be created
+as well, that dynamically change meaning depending on current status.
+
+USAGE
+* require this script from your main lua file
+* restart darktable
+* create shortcuts for each of the encoders on the x-touch mini
+  to a virtual slider under lua/x-touch
+  or import the following shortcutsrc file in the shortcuts dialog/preferences tab:
