Installing stuff

Setup page for quick reference.

Go

Best take would be to simply use Homebrew:

brew install go

As an alternative, one could download the binaries from golang.org, create a new folder (go) and export the workspace path to one’s bash profile:

echo "export GOPATH=Users/anirban166/Documents/go" >> .bash_profile

Follow up with a terminal reboot, then verify workspace path using echo $GOPATH.

This however, could lead to GOPATH entry is relative; must be absolute path: "Users/username/Documents/go"., as it did for me - but the prime reason I included this is so the reader can resolve this (which isn’t readily mentioned elsewhere) by following the steps I did:

• Remove your profile (must be /home or where cd ~ leads):

  rm  ~/.bash_profile
  

• Set workspace path to ./go (gonna create) and export to bash profile:

  export GOPATH=$HOME/go >> .bash_profile
  

• Set up the environment path:

  go env -w GOPATH=$HOME/go
  

• Check using go env GOPATH:

  /Users/anirban166/go
  

  Proceed to create directories and files as per the go/src/foldername/filename.go idiom:

  mkdir go
  cd go
  mkdir src
  cd src
  mkdir worldlines
  cd worldlines/
  touch worldlines.go
  

  Edit via your favourite editor, then use go run worldlines.go for running the file.

Rust

Browse through the official documentation, or follow along:

• Cmd C+V:

  curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
  

  Default settings¹ apply.

• Reboot terminal, update rustup:

  rustup update
  

• Check version to see if its correctly installed: (just like go version/git --version)

  rustc --version
  

  And yep, the c stands for compiler.

• Moving onto the IDE, I’ll be using VSC with the rust-analyzer extension or the rust language server/rls (if its still available as an extension). Don’t forget to set up cargo.

Note that its better to follow the updated docs or have a discussion with the members from the official Rust discord channel, instead of following relevant blog material, since they tend to get outdated with the proceedings of the language.

R

Homebrew again :)

brew install r

Set up RStudio + install.packages("devtools") and get started with the developmental (github) branch of testComplexity via devtools::install_github("Anirban166/testComplexity").
