Saner default for `transition-step` with `simple` transition

[demperor-music]

When did the issue start?

Since updating to the latest version, a week or two ago. I don't know for sure what the old version i was using was.

What is the issue?

The fade-in animation swww used to have when setting new wallpapers stopped working all of a sudden, so i had to change my configs to use other animations, which seem to work normally. When using the command manually, i noticed it gave me an error: failed to get cache path: failed to create cache_path: No such file or directory (os error 2).

What did i do to try and fix the issue?

Looked up the man pages and saw it would look for cache files in $XDG_CACHE_HOME/swww or $HOME/.cache/swww. ~/.cache/swww seemed to not exist so i made a new folder with the same name: nothing changed. I didn't have XDG_CACHE_HOME set, so i used XDG_CACHE_HOME=~/.cache/ swww img <PATH> to fix the issue, which worked in the sense that it stopped giving me the warning about the cache path, but still couldn't get the fade-in animation working.

The path warning problem has already been identified and fixed by @max-ishere in issue #86 and PR #88. The problem was a missing /.

When you say "fade-in", do you mean the simple animation? And by not working, do you mean it just does the transition instantly, or does it leave you with e.g. a black screen?

[demperor-music]

Yes sorry I meant the simple animation-type. And yes, it just does the animation instantly.

same issue here, would be willing to provide further info if needed

This is very strange. I can't seem to reproduce it here.

The only thing I can think of is that we changed the default value for --transition-step. Can you guys try something like swww img /path/to/img --transition-type simple --transition-step=1 for me?

[demperor-music]

That seemed to solve it for me. Thanks!

i think we cud implement bezier curves for simple too, the default bezier should be smooth enough

I don't know if that's a good idea. That would make --transition-step behave differently just for the simple transition. I think it would make things confusing.

I've made a very small change where --transition-step will default to 2 for the simple transition. From what I can tell, this will solve the problem @demperor-music and @weitcis were having.

Closing this for now.
