The current instructions for idris installation covers only Linux and Docker Images. As it turns out, installing on OSX is also rather straight forward. Namely, assuming homebrew has been installed,
bash -c "$(curl -fsSL https://raw.githubusercontent.com/stefan-hoeck/idris2-pack/main/install.bash)"
export PATH="$HOME/.pack/bin:$HOME/.idris2/bin:$PATH"
pack info
However, this is actually inaccurate. If one installed via pack on OSX, all the stuff would be installed under $HOME/.pack/bin. The directory$HOME/.idris2 won’t even exist.
I think the above info is probaby copied from the idris official home page, but in general the idris official info is severely out of date; and this part is no exception
