How to read value of an attribute in command chain?

[Animeshz]

Point of interest: store something on a temporary variable and reference its value next time.

Subshell doesn't work, as subshell is evaluated at the time of register of keybind. All subshells aren't doing what we want. echo under hc only echo's path of temp attribute, is there something like cat?

Example:

# Swap tags
hc keybind "$Mod-Control-Shift-$key" chain , \
    attr tags.focus.index "$i" , \                                               # swap tags index
    mktemp string swap_store , attr swap_store "$(hc attr tags.focus.name)" , \  # trying to swap names
    attr tags.focus.name "$(hc attr "tags.by-name.$i")" , \
    attr "tags.by-name.$i" "$(hc attr swap_store)"                               # unable to reference swap_store here

Probably, you are looking for the use_previous command.

you can create a custom variable with

hc new_attr string tags.my_swap_store

and you can copy another attribute's value into it via:

hc substitute NAME tags.focus.name attr_set tags.my_swap_store NAME

I fear that the rest of your command chain also does not make much sense (unless you really want to rename a tag via a keybinding).
