Setting up working environment

Published

Preface

This is just a note for myself to re-setup my working environment on Linux (I am using Ubuntu) so that I don’t forget what I need to do.

Terminal

Install `fastfetch`

sudo add-apt-repository ppa:fastfetch/stable
sudo apt install fastfetch 

# add `fastfetch` in `.bashrc` file.

Vim

Install Vim and set it as default text editor

sudo apt update
sudo apt install vim

sudo update-alternatives --config editor

Install `Vim-plugin`

Follow this link: LINK

Some plugins I use (Example of .vimrc file)

call plug#begin()

" List your plugins here
Plug 'sirver/ultisnips'
Plug 'lervag/vimtex'
Plug 'KeitaNakamura/tex-conceal.vim'
Plug 'arcticicestudio/nord-vim'
Plug 'preservim/nerdtree'

call plug#end()

let g:UltiSnipsExpandTrigger = '<tab>'
let g:UltiSnipsJumpForwardTrigger = '<tab>'
let g:UltiSnipsJumpBackwardTrigger = '<s-tab>'
let g:vimtex_view_method = 'zathura'
let g:vimtex_quickfix_mode = 0
let g:lightline = {'colorscheme' : 'nord'}

setlocal spell
set spelllang=en_us
inoremap <C-l> <c-g>u<Esc>[s1z=`]a<c-g>u

colorscheme nord

Setup `Vimtex` with `zathura`

Follow this: https://github.com/lervag/vimtex. Also remember that you need to install separate tex compiler to use tex.

Install R

Just follow this site: https://pmassicotte.github.io/linux-mint-dev-environment/installr.html.

I will just post my current .Rprofile file for reference:

if (interactive() && Sys.getenv("RSTUDIO") == "") {
  Sys.setenv(TERM_PROGRAM = "vscode")
  if ("httpgd" %in% .packages(all.available = TRUE)) {
    options(vsc.plot = FALSE)
    options(device = function(...) {
      httpgd::hgd(silent = TRUE)
      .vsc.browser(httpgd::hgd_url(history = FALSE), viewer = "Beside")
    })
  }
  source(file.path(Sys.getenv(if (.Platform$OS.type == "windows") "USERPROFILE" else "HOME"), ".vscode-R", "init.R"))
}

# Connect to public package manager
options(repos = c(CRAN = "https://packagemanager.posit.co/cran/__linux__/rhel9/latest"))

# This is important if you are using RSPM on Linux outside RStudio
options(HTTPUserAgent = sprintf("R/%s R (%s)", getRversion(), paste(getRversion(), R.version["platform"], R.version["arch"], R.version["os"])))
