Linux makes tabs when copying and pasting code

Question

I use Linux Ubuntu for competitive programming, it's pretty good, but when I copy and paste my c++ code to submit it, it automatically adds tabs to my submission code at the beginning of some lines.

Does exist some way to fix it?

Because on MS-windows it's not problem with this.

Thank you very much.

Welcome, you tagged the question with `sublime` and `vim`, but they are not mentioned in the question. Could you explain it with more detail? From where are you copying the code and paste where? — schrodingerscatcuriosity, Feb 10 '21 at 16:27

That's excellent news: it's not changing the content of your paste text — roaima, Feb 10 '21 at 16:41

Both vim and the Sublime Text editors are configurable on whether they use spaces or tabs for indenting and whether they convert existing tabs to spaces (or vice versa) or not.

For vim, see this question on vi & vim StackExchange. Basically, if you always want spaces instead of tabs, add set expandtab to your ~/.vimrc file. If you want to convert existing tabs to spaces, type :retab when in command mode.

For Sublime Text, see this part of its reference documentation. Basically, you probably want to set detect_indentation to false to prevent Sublime from attempting to adapt to the existing practice within each file you load, then set tab_size, use_tab_stops translate_tabs_to_spaces, auto_indent and trim_automatic_white_space according to your preferences.
