Dictionary functions for fish shell. These functions are based on bash 3 functionality, because fish does not yet support associative arrays.
This has been extracted from halostatue/fish-utils-core because these
functions are not core and should be installed on their own.
Note that these functions should only be used when there is no other alternative available, and there's usually an alternative.
Install with Fisher (recommended):
fisher install halostatue/fish-dict@1.xNot using a package manager?
Copy functions/*.fish to your fish configuration directory preserving the
directory structure.

Functions to give fish behaviour similar to associative arrays found in zsh
or bash 4. This is based on functions that I wrote for bash 3 and uses the
same technique.
dict:set x y # sets x{y} to an empty value
dict:set x y 1 # sets x{y} to the value 1
dict:set x y 1 2 3 # sets x{y} to the list value 1 2 3
dict:get x y # gets the value of x{y}
dict:has_key x y # true if key y exists in dictionary x
dict:empty x # true if there is no dictionary x
dict:keys x # the list of all keys in dictionary x
dict:count x # the number of keys found in dictionary x
