[Feature request] Finding all images in nested directories

[gurgalex]

Problem

Unable to view files existing at multiple levels in a nested directory.

Desired Behavior

Viewing of all the images listed.

# File tree of Pictures folder
image.png
dir1/image.png
dir1/depth2/image.png
dir1/depth2_2/image.png

Syntax

Is there a syntax to express that all images of certain types should be searched for up to a certain directory depth?

pseudo syntax
riv -f Pictures/**[*.png]/**[*.png]/*.png

Expected behavior

Find all images of type png in base Pictures folder.
Inside any directories in Pictures, find any png files.
Inside any sub-sub directories of Pictures find any png files.

Thoughts?

I'm not sure I understand. I'm pretty sure on zsh if I do riv **/*.png I get this behaviour. As for limiting the depth, this probably something that should be done by the shell. At runtime it's a different story, and I'll see if I can take it into account in #40. I'm not sure how to do this in bash.

[gurgalex]

Tested on zsh and it has the expected behavior. (4 of 4 images)

Bash shell only showed.

dir1/image.png

Closing as it is shell specific.

[gurgalex]

Hmm, may be a reason to bring back quoting globs.

riv "**/*.png" would have the same result regardless of shell expansion support (plus if a user has say 10k files and possibly reaches the max supported cli arguments for a program).

Closed in favor of #50

[Davejkane]

Yeah, I think I agree with you on this. Especially after doing a little bit of reading about bash. Also, I'll need this to take care of #40 anyway. Please close this issue anyway and I'll take care of it in that branch. Although I think it's going to be a nightmare coz I don't think that library you've linked does glob expansions.
