documentation of darktablerc

darktablerc

this files gives an overview over the default settings of the darktable configuration found in ~/.config/darktable/darktablerc. you might find some extra values in that configuration file that get generated by the code at runtime, this overview only has the default values that are specified during compile time. some details (like allowed range and factors when shown in the preferences dialog) are not shown here to not clutter the list too much. please have a look at the corresponding source file for up-to-date information.

key	type	default	description
allow_lab_output	bool	false	allow XYZ and Lab color spaces as output
	this is mainly useful for debugging and to create colorchecker lut styles externally.
ask_before_copy	bool	true	ask before copying images to new film roll folder
	always ask the user before any image file is copied.
ask_before_delete	bool	true	ask before erasing images from disk / discarding history stack
	always ask the user before any image file is deleted / history stack is discarded.
ask_before_move	bool	true	ask before moving images from film roll folder
	always ask the user before any image file is moved.
ask_before_remove	bool	true	ask before removing images from database
	always ask the user before any image is removed from DB.
ask_before_rmdir	bool	false	ask before removing empty folders
	always ask the user before removing any empty folder. this can happen after moving or deleting images.
bauhaus/scale	float	1.4	widget scale
	scaling factor for bauhaus widgets, will affect font size
brush_smoothing	enum low medium high	medium	smoothing of brush strokes
	sets level for smoothing of brush strokes. stronger smoothing leads to less nodes and easier editing but with lower control of accuracy.
cache_color_managed	bool	true	color manage cached thumbnails
	if enabled, cached thumbnails will be color managed so that lighttable and filmstrip can show correct colors. otherwise the results may look wrong once the display profile gets changed.
cache_disk_backend	bool	true	enable disk backend for thumbnail cache
	if enabled, write thumbnails to disk (.cache/darktable/) when evicted from the memory cache. note that this can take a lot of memory (several gigabytes for 20k images) and will never delete cached thumbnails again. it's safe though to delete these manually, if you want. light table performance will be increased greatly when browsing a lot. to generate all thumbnails of your entire collection offline, run 'darktable-generate-cache'.
cache_disk_backend_full	bool	false	enable disk backend for full preview cache
	if enabled, write full preview to disk (.cache/darktable/) when evicted from the memory cache. note that this can take a lot of memory (several gigabytes for 20k images) and will never delete cached thumbnails again. it's safe though to delete these manually, if you want. light table performance will be increased greatly when zooming image in full preview mode.
cache_memory	int64	(1024 * 1024 * 512)	memory in megabytes to use for thumbnail cache
	this controls how much memory is going to be used for thumbnails and other buffers (needs a restart).
channel_display	enum false color grey scale	false color	display of individual color channels
	defines how color channels are displayed when activated in the parametric masks feature.
codepaths/openmp_simd	bool	false	enable usage of OpenMP SIMD codepaths. if enabled, and such codepath exists, it will have the highest priority

codepaths/sse2	bool	true	enable usage of SSE2-optimized codepaths

compress_xmp_tags	enum never always only large entries	only large entries	store xmp tags in compressed format
	entries in xmp tags can get rather large and may exceed the available space to store the history stack in output files. this option allows xmp tags to be compressed and save space.
darkroom/ui/activate_expand	bool	false	expand the module when it is activated, and collapse it when disabled
	this option allows to expand or collapse automatically the module when it is enabled or disabled.
darkroom/ui/overexposed/colorscheme	int	1

darkroom/ui/overexposed/lower	float	2.0

darkroom/ui/overexposed/upper	float	98.0

darkroom/ui/rawoverexposed/colorscheme	int	0

darkroom/ui/rawoverexposed/mode	int	0

darkroom/ui/rawoverexposed/threshold	float	1.0

darkroom/ui/scale_precise_step_multiplier	float	0.1	the multiplier that is applied to any slider precise value change
	any slider value change will be multiplied by this number, when changing slider while holding CTRL modifier
darkroom/ui/scale_rough_step_multiplier	float	10.0	the multiplier that is applied to any slider rough value change
	any slider value change will be multiplied by this number, when changing slider while holding SHIFT modifier

	any slider value change will be multiplied by this number, when changing slider while NOT holding SHIFT or CTRL modifiers
darkroom/ui/scroll_to_module	bool	true	scroll to darkroom modules when expanded/collapsed
	when this option is enabled then darktable will try to scroll the module to the top of the visible list
darkroom/ui/sidebar_scroll_default	bool	false	mouse wheel scrolls modules side panel by default
	when enabled, use mouse wheel to scroll modules side panel. use ctrl+alt to use mouse wheel for data entry. when disabled, this behavior is reversed
darkroom/ui/single_module	bool	true	expand a single darkroom module at a time
	this option toggles the behavior of shift clicking in darkroom mode
database	string	library.db	database location
	filename relative to ~/.config/darktable or starting with a slash (needs a restart).
database_cache_quality	int	89	JPEG quality of on-disk thumbnails
	affects only the thumbnail cache used for quick startup.
host_memory_limit	int	1500	host memory limit (in MB) for tiling
	this variable controls the maximum amount of memory (in MB) a module may use during image processing. lower values will force memory hungry modules to process image with increasing number of tiles. setting this to 0 will omit any limit. values below 500 will be treated as 500 (needs a restart).
lighttable/ui/expose_statuses	bool	false	always show thumbnail overlays
	show overlays (rating stars, "edited" mark, etc) for all thumbnails in file manager, not only hovered one
lighttable/ui/preview/bottom_visible	bool	true	show bottom panel in preview mode

lighttable/ui/preview/header_visible	bool	false	show header panel in preview mode

lighttable/ui/preview/left_visible	bool	false	show left panel in preview mode

	this option toggles the behavior of shift clicking in lighttable mode
max_panel_height	int	400	maximum width of the side panels in pixels
	(needs a restart)
max_panel_width	int	500	maximum width of the side panels in pixels
	(needs a restart)
maximum_number_tiles	int	10000	assumed maximum sane number of tiles
	if during tiling this number is exceeded darktable assumes that tiling is not possible and falls back to untiled processing - with all system memory limits taking full effect. in case you want to process huge images you may want to increase this number.
metadata/resolution	int	300

min_panel_height	int	64	minimum width of the side panels in pixels
	(needs a restart)
min_panel_width	int	150	minimum width of the side panels in pixels
	(needs a restart)
never_use_embedded_thumb	bool	false	don't use embedded preview JPEG but half-size raw
	check this option to not use the embedded JPEG from the raw file but process the raw data. this is slower but gives you color managed thumbnails.
omit_tag_hierarchy	bool	false	omit hierarchy in simple tag lists
	when creating XMP file the hierarchical tags are also added as a simple list of non-hierarchical ones to make them visible to some other programs. when this option is checked darktable will only include their last part and ignore the rest. so 'foo\|bar\|baz' will only add 'baz'.
opencl	bool	true	activate OpenCL support
	if found, use OpenCL runtime on your system for improved processing speed. can be switched on and off at any time.
opencl_async_pixelpipe	bool	false	run OpenCL pixelpipe asynchronously
	if set to TRUE OpenCL pixelpipe will not be synchronized on a per-module basis. this can improve pixelpipe latency. however, potential OpenCL errors would be detected late; in such a case the complete pixelpipe needs to be reprocessed instead of only a single module. export pixelpipe will always be run synchronously.
opencl_avoid_atomics	bool	false	do not run OpenCL kernels which require atomic operations
	if set to TRUE darktable will not use OpenCL kernels which contain atomic operations (example bilateral). pixelpipe processing will be done on CPU for the affected modules. useful if your OpenCL implementation freezes/crashes on atomics or if they are processed with a bad performance.
opencl_checksum	string		checksum representing the setup of opencl devices on this computer
	darktable re-checks the performance benchmarks of your system in case your setup has changed, which is indicated by a change versus the stored checksum in this config variable; darktable de-activates opencl if the GPU benchmark lies below the one of the CPU; inital value is the empty string; set to OFF if you want to deactivate any automatic checks and prefer to do all configurations manually.
opencl_device_priority	string	/!0,///!0,*	priority of OpenCL devices for each pixelpipe type
	defines priorities on how (multiple) OpenCL devices are allocated to the different types of pixelpipe (full, preview, export, thumbnail, preview2). for more details visit our usermanual (needs a restart).
opencl_disable_drivers_blacklist	bool	false	whether to allow some partial opencl implementations to be used or not
	not all opencl implementations are fully-functional, there are at least two, which are not production-quality yet: pocl and beignet; therefore at this point in time, it is better to explicitly blacklist them by default. can be changed by setting this configuration option to TRUE (needs a restart).
opencl_library	string		system library with OpenCL runtime
	OpenCL runtime library is normally detected automatically by darktable. if your OpenCL runtime is at an unusual place and cannot be detected, enter the full pathname here. leave empty for default behavior.
opencl_mandatory_timeout	int	200	timeout period for locking mandatory opencl device
	time period (in units of 5ms) after which we give up try-locking an opencl device for mandatory use. defaults to 200.
opencl_memory_headroom	int	400	amount of OpenCL memory (in MB) which we assume as being reserved for the driver
	this amount of memory (in MB) will be subtracted from total GPU memory in order to calculate the available OpenCL memory. too low values will lead to out-of-memory situations in OpenCL processing. too high values will lead to unnecessary tiling (needs a restart).
opencl_memory_requirement	int	768	minmum amount of GPU memory (MB) required to activate OpenCL
	OpenCL will only be activated if your graphics card has at least this amount of memory. reducing the value will allow cards with less GPU memory to be used - but at the risk of lower system stability and occasional crashes. values below 200 will be treated as 200.
opencl_micro_nap	int	1000	pause OpenCL processing for this number of microseconds from time to time
	for slow GPUs this gives your graphics driver some time to breathe to do needed screen updates. can be left at zero for fast devices.
opencl_number_event_handles	int	25	the number of OpenCL event handles darktable can use
	a positive non-zero integer defines the number of event handles that darktable may have opened on a device. a value of -1 does not pose any restrictions, bearing the risk of hitting the device's resource limits. a value of zero completely prevents the use of event handles.
opencl_scheduling_profile	enum default multiple GPUs very fast GPU	default	OpenCL scheduling profile
	defines how preview and full pixelpipe tasks are scheduled on OpenCL enabled systems. default - GPU processes full and CPU processes preview pipe (adaptable by config parameters); multiple GPUs - process both pixelpipes in parallel on two different GPUs; very fast GPU - process both pixelpipes sequentially on the GPU.
opencl_size_roundup	int	16	round OpenCL work group sizes to a multiple of
	in OpenCL processing round width/height of global work groups to a multiple of this value. reasonable values are powers of 2. this parameter can have high impact on OpenCL performance.
opencl_synch_cache	enum true active module false	active module	cache intermediate OpenCL output
	active module (default) - cache the input to the currently focused module, which allows for faster response time when making multiple adjustments to that module (though the whole pipeline may need to be reprocessed when another module is changed); true - cache the output after each module, which may improve speed, as the whole pixelpipe won't be reprocessed on every parameter change, though will require more memory transfers from the GPU; false - do not sync the pixelpipe cache from OpenCL, which avoids memory transfers from GPUs fast enough to smoothly reprocess the whole pixelpipe.
opencl_use_cpu_devices	bool	false	whether to make use of CPU OpenCL devices
	typically darktable's hand-optimized CPU code is much faster than any OpenCL-on-CPU code; therefore CPUs are excluded from being used as OpenCL devices by default. can be changed by setting this configuration option to TRUE (needs a restart).
opencl_use_pinned_memory	bool	false	whether to use pinned memory transfer during tiling
	during tiling huge amounts of memory need to be transferred between host and device. for some OpenCL implementations direct memory transfers give a drastic performance penalty. this can often be avoided by using indirect transfers via pinned memory. other devices have more efficient direct memory transfer implementations. AMD seems to belong to the first group, nvidia to the second.
panel_scrollbars_always_visible	bool	true	always show panels' scrollbars
	defines whether the panel scrollbars should be always visible or activated only depending on the content. (need a restart)
performance_configuration_version_completed	int	0	version of the last completed performance configuration
	what was the last performance configuration which has been completed
pixelpipe_synchronization_timeout	int	200	timeout period of pixelpipe synchronization
	time period (in units of 5ms) after which synchronization of preview and full pixelpipe is assumed to have failed. set to zero to omit pixelpipe synchronization. defaults to 200.
