Every time a new terminal session starts asdf adds new lines to the .zshrc file

[overtune]

Describe the bug

Everytime I start a new session in a terminal (like opening a new tab in iTerm) my .zshrc file is updated with new lines containing:

. /usr/local/opt/asdf/asdf.sh

. /usr/local/opt/asdf/asdf.sh

To Reproduce

I have updated asdf to the latest version on Homebrew and use it with Oh My Zsh.

Expected behavior

It shouldn't append new lines to .zshrc evertime a new session is started.

Somewhere along the line you are sourcing code that does something like

echo -e "\n. $(brew --prefix asdf)/asdf.sh" >> ~/.zshrc

See if you can find that anywhere.

There is a language differnce in the "Add to your shell" section for Homebrew vs Git in the docs.

With Homebrew we say

Add asdf.sh to your ~/.bash_profile with:
echo -e "\n. $(brew --prefix asdf)/asdf.sh" >> ~/.zshrc

This is a command you should execute in your terminal, so brew prefix is computed once on setup.

With Git we specify

Add asdf.sh to your ~/.bash_profile with:
. $HOME/.asdf/asdf.sh

These are the contents you should add manually to your Shell config.

As @seivan says, you probably have the whole echo command in your Shell config so it is appending every time.

We had updated the Homebrew section to be consistent with the Git method, but computing brew prefix is expensive and slowed peoples Shells.

Thanks!
You're right, I did had the whole echo row in a file that was sourced in my .zshrc. That's why I didn't found anything when I search for asdf in my .zshrc.
Feeling dumb :)
But thanks for pointing out this!

It's not your fault, the docs are different depending on system. Ideally the flow should be the same. Hopefully some other changes will make this easier in the future. Thanks for giving asdf a go :)
