Ask HN: It's 2018, tabs or spaces?

Spaces. Tabs are invisible and mess stuff up if mixed with spaces.

Well... https://ukupat.github.io/tabs-or-spaces/

Both. Tabs for indents. Spaces for alignments after the indent level is reached.

Everyone can view code with their preferred indent width. Perfect solution with no flaws or drawbacks. Maybe 1 drawback, it requires advanced tooling (emacs smart-tabs-mode) to automatically handle the indentation/alignment.

Indent width is a visual effect. Mandating an indent width with hard spaces is like mandating the color scheme.

Let's not do this again.

Spaces, now and forever.

Both!

tabs, so everyone can choose their own display width

Whatever the rest of the team uses. For personal projects: whatever is idiomatic for that language.

Spaces. Your editor should convert the tab key to spaces.
