Autojump: What to source to make this work on macOS after installing with Homebrew?

did you try the part where it says "read the post installation instructions"?

https://github.com/wting/autojump#installation

I have. For macOS, it only says to brew install it and that's it.

and brew install shows you instructions after install. There is a reason it's there.

https://github.com/Homebrew/homebrew-core/blob/b6b9f36c8744c2259b74f12850163c676ae49396/Formula/autojump.rb#L27-L35

you can see the caveat again using command

brew info autojump

and it will give you the output

autojump: stable 22.5.1 (bottled), HEAD
Shell extension to jump to frequently used directories

==> Caveats
Add the following line to your ~/.bash_profile or ~/.zshrc file (and remember
to source the file to update your current session):
  [ -f /usr/local/etc/profile.d/autojump.sh ] && . /usr/local/etc/profile.d/autojump.sh

If you use the Fish shell then add the following line to your ~/.config/fish/config.fish:
  [ -f /usr/local/share/autojump/autojump.fish ]; and source /usr/local/share/autojump/autojump.fish

zsh completions have been installed to:
  /usr/local/share/zsh/site-functions

Still doesn't work for me even after adding [ -f /usr/local/etc/profile.d/autojump.sh ] && . /usr/local/etc/profile.d/autojump.sh & sourcing the file.

I do j <dirname> and am left in my current directory instead of changing dirs.

You have to cd <dirname> first than autojump will remember it for you the next time you call j <dirname>

Ahh, gotcha, I misunderstood the purpose, so then autojump is more about remembering where you've been so you can go back there quickly rather than finding a deeply nested subdir from your current location?

Yes, as cited from the README.md

It works by maintaining a database of the directories you use the most from the command line.

_Directories must be visited first before they can be jumped to._

I'm also running into this issue.
After installing through Homebrew, I added this to my .bash_profile:
[ -f /usr/local/etc/profile.d/autojump.sh ] && . /usr/local/etc/profile.d/autojump.sh
I also made sure to add:
export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ;} history -a"

After cd'ing into a few directories, j -s has no entries. I have to manually run the .bash_profile line in my current session. Is this a config issue with my .bash_profile somehow?

having the same issue as @helenes-r7

After installing through Homebrew, I added this to my .bash_profile:
[ -f /usr/local/etc/profile.d/autojump.sh ] && . /usr/local/etc/profile.d/autojump.sh

After cd'ing into a few directories, j -s has no entries.

And yes, I did source ~/.bash_profile to reload the session

@helenes-r7 @l-gothberg You can read about the question here https://apple.stackexchange.com/questions/12993/why-doesnt-bashrc-run-automatically

Thanks @bendem and @aphe for chiming in.

Autojump is a unique in the sense that it requires post-installation setup since every users are using different shells and potentially customized setups, and some package distributions don't allow post install configuration (e.g. Debian).

I plan on improving the post installation step in #323 so please redirect feedback there.

It would be great to have this in the readme:

[ -f /usr/local/etc/profile.d/autojump.sh ] && . /usr/local/etc/profile.d/autojump.sh

I didn't read the post install instructions (sorry!), I just assumed it would work out of the box.
Maybe this can also be added next-to/instead-of "read post install instructions"
