Some notes from a recent POOH meeting I thought might be useful

.bash_profile is sourced when you first log on to the farm head node.
.bashrc is sourced when you are on a node, after doing an srun. (I think)

make .bash_profile

If you don't have a file in your home directory called .bash_profile,
make one with

cp ~/.bashrc ~/.bash_profile

Conda note: if you dont have the (base) at the front of your prompt on the head node,
even though you installed conda, creating a .bash_profile this way could possibly fix this!

add to .bash_profile

(Using nano) paste the following at the top of your .bash_profile

If you have other stuff in your .bash_profile, (e.g. conda stuff) probably leave it there and just put this at the top

# >>> INFO >>>
    # This is .bash_profile 
    # .bash_profile is sourced when logging into farm head node.
    # When logging into a node (with srun), farm sources .bashrc
    
    # Note, you can set .bashrc to pull from this file.
    # additionally, you can override some of the settings from
    # .bash_profile by adding to the bottom of .bashrc:
    # source /home/{YOUR_USERNAME}/.bash_profile 
# <<< INFO <<<


# >>> coloring the terminal >>>
    # This colors files and diretories with ls
export CLICOLOR=1
export LSCOLORS=ExFxBxDxCxegedabagacad
alias ls='ls --color=auto'


    # This colors the prompt

Is vim causing you tabs vs spaces problems?

The best option is to not us vim (jk...?)

Alternatively, the following can be pasted in ~/.vimrc so that
tab gets converted to 4 spaces when you save.

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
" => Text, tab and indent related
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
" Use spaces instead of tabs
 set expandtab
" Be smart when using tabs ;)
 set smarttab
" 1 tab == 4 spaces
set shiftwidth=4
set tabstop=4
" Linebreak on 500 characters
"set lbr
"set tw=500
"set ai "Auto indent
"set si "Smart indent
"set wrap "Wrap lines

I also have the following in my .vimrc, it adds some syntax highlighting.
It as been helpful for me, ymmv

au BufNewFile,BufRead Snakefile set syntax=snakemake
au BufNewFile,BufRead *.snake set syntax=snakemake
au BufNewFile,BufRead *.snakefile set syntax=snakemake

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
" => Colors and Fonts
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
" Enable syntax highlighting
syntax enable
colorscheme murphy
set background=dark
" Set utf8 as standard encoding and en_US as the standard language
set encoding=utf8
" Use Unix as the standard file type
set ffs=unix,dos,mac
