Usage with fzf, new options (maybe?)

[nebulosa2007]

When you write yabsnap list it shows all information about snapshopts, but when you want delete some of them it will be not so easy, because name of snapshots is 14-digit timestamp, that really hard to enter, only copy and past.

For convinience you can use the fzf in that scenario (e.g. bash alias snapctl): ls -d /.snapshots/*/ | sed 's/\/.snapshots\///g;s/\/$//g' | fzf -m --reverse --preview 'echo -n $(basename {1})": "; cat /.snapshots/{1}-meta.json | echo $(tr -d "\"}{")' --preview-window right:70%:wrap | xargs -I snap sudo yabsnap delete /.snapshots/snap'

It works as expected and already could be mentined in README, but really wants use yabsnap with fzf like that: yabsnap list -q | fzf ... --preview yabsnap list {1} | xargs ... yabnsap delete ... , where:

yabsnap list -q it lists names of snapshots, yabsnap list PATH|TIMESTAMP [--oneline] shows info only for one snapshot (--oneline- comma-separared info in one line)

Any thoughts?

In other words we should have a machine/bash readable output.

Totally agree.

Let's also make the oneline mode output json to keep it structured.

This will solve both the issues -

1. Get a machine / bash parseable output.
2. Keep any such parsing robust towards future changes.

Also it's very easy to restructure with jq.

As a quick illustration we could then have something like this -

$ src/yabsnap.sh list-json
{"comment":"pacman -S jq","config_file":"/etc/yabsnap/configs/root.conf","file":{"prefix":"/.snapshots/root-","timestamp":"20231029172350"},"source":"/","trigger":"I"}
{"comment":"","config_file":"/etc/yabsnap/configs/home.conf","file":{"prefix":"/.snapshots/home-","timestamp":"20231026183029"},"source":"/home","trigger":"S"}
{"comment":"","config_file":"/etc/yabsnap/configs/home.conf","file":{"prefix":"/.snapshots/home-","timestamp":"20231027234159"},"source":"/home","trigger":"S"}

It is also easily restructured by jq (which may then also be strimed to fzf), for instance -

$ src/yabsnap.sh list-json | jq '.file.prefix+.file.timestamp
"/.snapshots/root-20231029172350"
"/.snapshots/home-20231026183029"
"/.snapshots/home-20231027234159"

Hope this proposed addition makes sense.

Implemented a new arg to do this, yabsnap list-json.

Sorry - I saw it and fixed it, but forgot to release to AUR.

Released now, 2.0.11 should install fine.

[nebulosa2007]

Thx, now works as expected!

Example of usage: yabsnap list-json | jq -r '.file.timestamp' | fzf -m --reverse --preview 'yabsnap list-json | grep {1} | jq -r .comment' | xargs -I{} sudo yabsnap --dry-run delete {}

Eye candy example: yabsnap list-json | jq -r '.trigger+" "+.file.timestamp' | fzf -m --reverse --preview 'yabsnap list-json | grep {2} | jq -r .comment' --preview-window right:70%:wrap | xargs -I{} echo {} | cut -d' ' -f2 | xargs -I{} sudo yabsnap --dry-run delete {}
