There’s this cool python script chromexup that allows declaratively managing chromium based extensions. 

Basically setup the configuration in the right place, find the extension id from the Chrome web store and run chromexup.

ini 
[main]
branding           = chromium
remove_orphans     = True
parallel_downloads = 4

[extensions]
BlankNewTabPage   = jaadjnlkjnhohljficgoddcjmndjfdmi
JavaScriptToggle  = cdcgbgnfhhdmdkallfmlachogpghifgf
NoHistory         = ljamgkbcojbnmcaonjokopmcblmmpfch
~/.config/chromexup/config.ini

Side note: NoHistory is good for disabling history (Firefox has options). If the history/bookmarks database gets too large, funky auto–suggestion stuff can happen (100% processor usage). , it’s best not to trust browsers storing bookmarks anyway and use an independent tool/method. The less data coupled to browsers the better — at least if you’re like me and swap browsers regularly.

Different words similar meaning? --references is NixOS speak for direct package dependencies. --requisites list all. These work with the nix-store command.

shell 
$ readlink --canonicalize "$(type -P which)"
/nix/store/r78jv9xgxnvsm5vpasf5ldkc28pkri6r-which-2.21/bin/which

$ nix-store --query --references /nix/store/r78jv9xgxnvsm5vpasf5ldkc28pkri6r-which-2.21
/nix/store/4nlgxhb09sdr51nc9hdm8az5b08vzkgx-glibc-2.35-163

which directly depends on glibc. Swap --references to --referrers for paths pointing to which.

On Guix, list/draw dependencies with guix graph.

shell 
guix graph --type=references which
