zsh history - full path

Question

Suppose I do the following in zsh

cd ~
cd dir1
cd dir2
cd dir3
evince foo.pdf

zsh writes exactly the same in its history file.

Now my question is whether it is possible to have

cd ~
cd ~/dir1
cd ~/dir1/dir2
cd ~/dir1/dir2/dir3
evince ~/dir1/dir2/dir3/foo.pdf

in zsh history instead. I.e. that zsh remembers only full paths.

Related (but different): Can I have my shell history record how wildcards expanded? I don't think there's a way to change what's recorded in the history, but you can clumsily record extra stuff in parallel. — Gilles 'SO- stop being evil', May 07 '11 at 12:42
A simpler and better alternative would be if zsh could record the PWD of every command in its history. So before executing a command from history it could prompt you if your current PWD dosesn't match the command's PWD — HRJ, Nov 06 '14 at 11:06
Just found out that oh-my-zsh has a plugin for per-directory-history! — HRJ, Nov 06 '14 at 11:14

Not in a general way, because the shell has no way to know whether a given argument is a relative path or not. Of course it could use some heuristics (similar to the ones used for completion), but this might be too error-prone.

zsh history could log the full path before the command runs. The end user can then figure out what maps to a relative directory and what doesn't. – Alok Sep 21 '16 at 22:12
You could try arguments in a $(realpath $arg) subshell in a zshaddhistory-hook and if it fails you know its not a path. Add some initial regex validation and you're pretty close imo. – dza Nov 12 '22 at 12:08
