I want to get a list of all environment variables (shell variables? exported variables?) and their values at a given time, in zsh.
What is the proper way to do this?

Bash – Print Only Defined Variables

"Are there other commands which prints only the shell variables, without the functions?"

In man bash, in section SHELL BUILTIN COMMANDS (in the set section) it says: "In posix mode, only shell variables are listed."

(set -o posix; set)

note: () syntax spawns a subshell, if you don't like forking just use the more verbose version

set -o posix; set; set +o posix

List all shell variables

bash : use set -o posix ; set. The POSIX options is there to avoid outputting too much information, like function definitions. declare -p also works.

zsh : use typeset

Shell variables and environment variables

An environment variable is available to exec()-ed child processes (as a copy. if parent process change the variable, the child environment is not updated). A non-environment variable is only available to the current running shell and fork()-ed subshells. This distinction is present in all shells.
