what's wrong with that?!
I'm sure that made sense once to save disk space for the

wouldn't replacing spaces with tabs do that? Were disks ever
*that* small? I've worked on old mini-computers and even
then we didn't try to save space at the *source* level.
The project's normal rule is "don't
reformat unnecessarily" since it makes source control merge/diff
difficult.
use a decent configuration control system and make sure
you don't mix source code changes with reformats. Clearly label
the reformat versions.
can't help you with indent

Tab width 8 is the norm elsewhere, at least in the Unix world and with
published ASCII text. So some code gets written with tab-width 4, some
with 8. Even if everyone sets indentation = tab-width, code still gets
misaligned. This written with tab-width 4 (I've substituted spaces):
int foo; /* hi there */
const char *barbaz[256]; /* and here */
becomes this when displayed with tab-width 8:
int foo; /* hi there */
const char *barbaz[256]; /* and here */

Not if tab width indentation level. (e.g. 8 and 4).
Were disks ever *that* small? I've worked on old mini-computers and
even then we didn't try to save space at the *source* level.
Who knows. If the point was not to save space, I have no idea at all
what the point was.

Actually I'm not sure what a configuration control system is, as opposed
to source control. This project is still using CVS, and I'm not going
to fight about that. In any case the reformatting changes will
certainly not pay attention to the "don't reformat" rule:-)

The point of using tabs is that everyone can easily convert to something
convenient. I find a value of 4 spaces perfect, some prefer 2, some
prefer 8. I've also seen 3.
You suggest that you switch to 8 spaces (i.e. no tabs) which seems to me
like a really not that good idea. After all everyone should be able to
display it the way he/she wants - not the way the programmer liked it.
Code indented by spaces is an annoying pest, IMHO.

If you wish to maintain vertical aligment for whatever reason, then
you have to use spaces.
Of course having vertical alignment in source code is a matter of
personal taste
Reducing indent (tab) size increases the number of nested blocks that
dont require line wrapping, or allows the use of longer variable
names.
Increasing the indent size reduces the risk of vertical alignment
being upset if the tab size is changed as possibly only a single tab
is required to maintain alignment

Apparently you never coded C under CP/M 80 on single density 8" floppy
disks.
Or Pascal on early micros where the storage medium was a cassette
tape. I say Pascal, because I don't actually remember a
cassette-based C for the original TRS-80.

Forget the disks, getting the source in memory was enough of a challenge!

Er no, but thats a religious war so don't go there.
So some code gets written with tab-width 4, some
with 8. Even if everyone sets indentation = tab-width, code still gets
misaligned. This written with tab-width 4 (I've substituted spaces):
int foo; /* hi there */
const char *barbaz[256]; /* and here */
becomes this when displayed with tab-width 8:
int foo; /* hi there */
const char *barbaz[256]; /* and here */
So reset your editor to use tab widths of 4. Job done.

I should have clarified: The code was _originally_ written with tab
width 4. But by now it's sprinkled with quite a bit written with tab
widht 8. Open-source project, several authors... So it gets wrong
either way.

That doesn't make sense to me. A Tab is a tab - your editor should
convert 0x09 into whatever tabspace you've defined in your editor.
Presumably you mean that some moron has tab-to-spaced your code twice,
once at 4s/t and once at 8s/t.
In which case why not just run it through indent, setting appropriate
tabs (not spaces)? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
