Lang

Go

Follow official installation - https://go.dev/doc/install.

My directory would be /Users/$USER/Library/.

Some modification on config according to your installation directory. Below is my config, you can make your own.

go env -w GOPATH=/Users/$USER/Library/go
go env -w GOMODCACHE=/Users/$USER/Library/go/pkg/mod
go env -w GO111MODULE=auto

Python

conda, even miniconda is heavy, pyenv is light-weight and straight-forward.

conda is easier, however, make your own choice. I prefer pyenv.

brew install pyenv
brew install pyenv-virtualenv

pyenv install 3.12.0
pyenv global 3.12.0
# pyenv virtualenv 3.12.0 <COSTUM_NAME>
# pyenv global <COSTUM_NAME>

Javascript

use fnm command line tool

Rust

use rustup

# config for rustfmt, i use tab_spaces = 2 
ln -s ~/.config/rustfmt/ /Users/humborn/Library/Application\ Support/rustfmt

Main

plz refer to my dotfile.
