How can I (from a script) add something to the zsh command history?

I'd like to be able to look through my command history and know the context from which I issued various commands--in other words, "what directory was I in?" There are various ways I could achieve this, but all of them (that I can think of) would require manipulating the zsh history to add (for instance) a commented line with the result of $(pwd). (I could create functions named cd & pushd & popd etc, or I could use zsh's preexec() function and maybe its periodic() function to add the comment line 开发者_StackOverflow社区at most every X seconds, just before I issue a command, or perhaps there's some other way.)

The problem is, I don't want to directly manipulate the history file and bypass the shell's history mechanism, but I can't figure out a way (with the fc command, for instance) to add something to the history without actually typing it on the command line. How could I do this?

You can use the print -s command (see man zshbuiltins) to add anything you want to the history. There's also a hook function you can create called zshaddhistory (see man zshmisc) that can manipulate history contents as they are created.

See my Bash history logging functions for inspiration.
