EMACS PYTHON INDENT BLOCK HOW TO

I personally don’t use it, but it might tickle your fancy. The Smart-tabs-mode package helps Emacs indent with tabs and align with spaces in various languages. ( setq backward-delete-char-untabify-method 'hungry ) SmartTabs (Bonus) Instead of backspacing the whole tab, it backspaces the tab one space at a time. Making Backspace Properly Delete TabsĮmacs has a strange default behavior when backspacing tabs. You can view a list of ascii character IDs here. The line that is a little bit confusing to read is the one where we actually set the pipe character.Īll you really need to know about it is that 124 is the ascii ID of the pipe character (“|”). This is an example of #c1c1c1 on a light background. This is an example of #636363 on a dark background. If you’re using a light theme in Emacs, you’ll want a lighter color such as #c1c1c1. I set the text color of our pipe character to be #636363 which is a nice color if you’re using a dark-themed Emacs theme.

After that, you’re calling custom-set-faces to customize the appearance of the tab whitespace.

I am not completely sure why, but they are needed in order to set the color of the pipe character.

Next, you’re setting the whitespace style to show tabs and trailing whitespace.

This makes our configured whitespace visible in all buffers automatically.

First you enable global-whitespace-mode.

The first four lines of the snippet are pretty easy to understand.

I have separated the whitespace-display-mappings portion of the snippet with a newline because it is the more confusing-to-read part of it. ( global-whitespace-mode ) ( setq whitespace-style ' ( face tabs tab-mark trailing )) ( custom-set-faces ' ( whitespace-tab (( t ( :foreground "#636363" ))))) ( setq whitespace-display-mappings ' (( tab-mark 9 )))

If you want to highlight spaces too, please refer to ErgoEmacs’ article on making whitespace visible. We will accomplish this by making tabs appear visible as a “|” (pipe) character. They are both whitespace characters that can easily be confused for eachother. Something that I feel that is very important to have in an editor is a way to identify spaces and tabs easily.
