Over the weekend, I was working with someone who uses spaces over tabs in all
the programming that they do. Their editor wasn't properly configured to
switch when using make, and so they got the classic "missing separator." error
message. Today, I learned that make already has a special error for an
eight-space indent, "missing separator (did you mean TAB instead of 8
I know eight spaces is classic, but many languages use two or four space
indents as a style. Would there be any interest in also adding messages for
these cases? I have written a simple patch for this, but since I'm not a
project member, cannot submit it directly.
Is there any interest in a patch for this? My current iteration is to do the
simplest thing, and detect 2 and 4 directly, but I think with some work I
could make it detect an arbitrary number, if that's preferred. Thoughts?
I'm not that excited about this idea. The problem is that lots of makefiles
indent their variables, rules, etc. For example inside "ifeq" statements, or
even just to right-align variable assignments. Having warnings about changing
to TAB on most even-spaced indentations seems like it could be more confusing
So, I am not incredibly familiar with the codebase, but this is seemingly on a
code path where an error is already going to happen; ie, this is a more
specific form of error, rather than changing something that would have
previously been parsed successfully into a failure. I would certainly agree
that breaking such things wouldn't be good.
