[gentoo-dev] About how many spaces a tab represents

[gentoo-dev] About how many spaces a tab represents

[Pacho Ramos]

I noticed this problem now that joe was modified to comply with this
rule set in devmanual:
http://devmanual.gentoo.org/ebuild-writing/file-format/index.html#indenting-and-whitespace

It stated a tab represents 4 spaces. Where does this rule come from? Why
8 spaces wasn't chosen instead? I say that because looks like 8 spaces
equivalence is used by tools like "cat", "less", even CVS reports in
gentoo-commits show tabs as 8 spaces instead of 4. 

Thanks for the info

Hysterical raisins. Unfortunately drobbins mandated it that way early
on, because he didn't use a proper text editor.

AFAIK, there's no standard that specifies the positions of tab stops,
so multiples of 4 are as good as anything else. Different text editors
have different defaults (Emacs uses multiples of 8, but it's easy to
change).

Of course, once you have a convention that is widely followed, it's
wise not to change it ...

Hmm, does that have implications on anything else but counting line
width?

Well, I was a bit surprised an ebuild I was thinking was looking in a
way, was really shown a bit different when, for example, simply running
less over it :/

A tab is a tab. How wide it is, is up to you. The convention is that
four spaces should be replace by a tab. You can configure tab width
for your terminal with:

    setterm -regtabs 4

If you want to, that is.
