The tab in VIM

tab and indent are not the same thing.

tab is a character (tab) whose display width can be defined. You can change the mapping of the TAB key, set it to n spaces, and N is determined by the tab width. Indentation refers to a concept in vim that can be controlled by the > and < keys to increase and decrease the indent, the indentation of the filling unit can be a tab or a space, determined by the state of Expandtab (Noexpandtab/expandtab). The amount of indentation produced by a ">" operation can be customized, not necessarily consistent with the tab width.

The following is the corresponding Setup command for VIM:

Set Expandtab             change the tab map to a space set tabstop=2             set tab width set softtabstop=2         set backspace fallback amount set shiftwidth=2          settings ' > ' and ' < ' indent

Tabs can sometimes cause problems, such as mixing tabs and spaces during Python indentation, causing the program to get an error. Discard tabs in the future, mapping the TAB key in Vim and gedit to two spaces. In order to prevent tab trouble can be set in Vim as follows, eye-catching display tabs:

Set Listset listchars=tab:?
