Re: [darktable-user] Do I need to install Lua?

[Bernhard]

Hi Bill,

thanks for the somewhat longer answer. I did a german language 
description of your work in my blog here 
https://www.bilddateien.de/blog/2018-08-19-addons-fuer-darktable.html 
and wanted to get things right.

The short answer is yes, and you should use lua5.3 (i.e. sudo apt-get 
install lua5.3).


darktable has a built in copy of lua.  It's enabled on windows, and 
I'm not sure about MacOS.  It's disabled on linux in favor of an 
external version of the interpreter.

Now William published his script manager and I was reading his
documentation, but also the darktable docs
https://www.darktable.org/usermanual/en/lua_chapter.html and found
no reference to that.

So the question is:
Do I really need those packages or is there something like a lua
interpreter built inside darktable?

All my Macs have Retina displays, but the MacBook is a 13” and has a comparable 
resolution to the Surface. Nevertheless, Darktable is much more usable on 
Windows than on the (faster) MacBook.

All the SSL certificates under *.darktable.org seem to have expired yesterday, 
and whoever is managing the LetsEncrypt setup probably forgot to turn on 
auto-renew :)

CPU load does increase a fair bit when I move the mouse. Not up to 100%, but 
rather too much for comfort. Reading through the issue description does make it 
seem like the entire lighttable is being redrawn on every mouse move, which is… 
sobering. From the descriptions there doesn’t seem to be enough event filtering 
to figure out if the redraws are warranted.

Well, that kind of negates the point of having a lighttable… One of the reasons 
I switched to Darktable is the library management features, and the (relative) 
ease for triaging shots…

Thanks for the enlightening reply,

R.

I’m using 2.4.4, and the “trash” yes/no confirmation is the latest offender :)

Re: [darktable-user] Mac version UI performance/lag

[J Albrecht]

As I had noted earlier and elsewhere, I also run dt (2.4.4) on a Mac:
MacBook Pro (Retina, 13-inch, Late 2013)
2.6 GHz Intel Core i5, 8 GB 1600 MHz DDR3
Occasionally, I also have the program running on a linux (Fedora) desktop.

I’ve no complaints about dt’s performance on either system. Nor have I noticed 
differences. Yet perhaps if I’m inclined to experience the performance of a 
tricked-out Porsche, I might be compelled to make some changes. Meanwhile, I’m 
quite content, happily zipping along the autobahn in my fancy VW.

Re: [darktable-user] Mac version UI performance/lag

[Per Östlund]

Hi,

Does your Macs have much higher resolution than your other computers 
perhaps? There's an old issue that causes the lighttable to be almost 
unusably slow on very high resolutions like 4K, and Macs tend to have 
very high resolution screens. See 
https://redmine.darktable.org/issues/10764 (the bug tracker seems to 
have some issues right now though).


Just moving the mouse cursor around on the lighttable will cause 100% 
CPU usage if that's the issue you're having. One workaround is to make 
the darktable window smaller, since the issue seems to get exponentially 
worse the larger the window is.


Cheers,
Per Östlund

Hi there,

I’ve been using Darktable for over a year now, and find it slightly awkward 
that the Mac version is much less performant (I’ll explain exactly why in a 
second) than the Linux and Windows ones.

I’m comparing it across four machines:

- iMac 3,4 GHz Intel Core i5, 8GB RAM
- MacBook 3.3 GHz Intel Core i5, 16GB RAM
- Acer C720 1.4 GHz Intel Celeron, 2GB RAM (Ubuntu)
- Surface Pro 2.4GHz Intel Core i5, 8GB RAM

When handling the exact same set of photos (no RAW, only 200 JPEGs up to 16Mpx, 
synced via Dropbox), the Mac version struggles to do basic navigation, lagging 
a lot when compared to the Linux and Windows versions.

Photo manipulation is faster, but it is as if the GTK<->Cocoa layer imposed a 
half-second lag on every keypress, which is very noticeable when browsing images in 
the light table, and makes simple operations like rating and multiple selection 
almost impossible to perform in a single attempt.

Even selecting presets and file navigation (just the UI, not the actions 
themselves) feel unbearably slow, and it is awkward to fire up the little 
Ubuntu netbook and have things work snappily (UI-wise).

On Windows (10), things work OK, other than minor oddities with the trackpad 
handling (which I’ll defer to another thread). I don’t see anywhere near as 
much lag as on the Mac.

I’ve gone through the mailing-list archives (yeah, that sort of pegs my age) 
and have seen little or no mention of Mac issues, so I’m guessing there are few 
people using Darktable on macOS, and no hints as to the causes or likely 
resolution.

I’ve also been tracking https://redmine.darktable.org/issues/10887#change-35040 
for a while, but would like to know if there are more folk with the same issues.

(Also, I’ll be filing an issue on the way full screen is handled, since dialog 
boxes work quite poorly in that mode — they’re always stretched to the full 
display, which is kind of awkward in the case of yes/no prompts on a 27” 
display…)

I use mac and latest version of darktable and I haven’t noticed nothing.
Only thing is that when adding point to tone curve, it might reset it self
just like that. Maybe it’s mouse contct issue, I don’t know.

Which version are you using? This bug should have been fixed in 2.4.
Which dialog boxes are still fullscreen?

[darktable-user] Do I need to install Lua?

[Bernhard]

Hi,

I installed Lua on my system to run the scripts for darktable as I read 
something about this some time ago.


|sudo apt-get install -y liblua5.2-0 liblua5.2-dev lua5.2 lua5.2-doc|

Now William published his script manager and I was reading his

https://www.darktable.org/usermanual/en/lua_chapter.html and found no 
reference to that.


So the question is:
Do I really need those packages or is there something like a lua
