Control the tab/indention settings using svn properties
Hi,
I have briefly discussed this with one of the Ankh team. He recommended
me to drop off the idea in this forum.
When working with other people, and code from other groups, the tab
settings generally vary. Generally, that is very annoying.
My suggestion is: Invent a few official subversion properties to control
the settings. Like svn:tab=8 svn:indent=4 svn:tabfill=space or
svn:tab=8,4,S .
It seems that the above might be feasible for the Ankh plugin, so I'm
now submitting this idea to a wider audience. There are several tools
and plugins that could be enhanced to use thses properties if they
become official.
Regards,
/Micke

I'm sure they can agree on some sort of property if the Ankh team can
make it work (you never know with M$ stuff)...

Thank you for seeing and commenting the idea and not the faults in the
suggestion.
The thought behind Subversion pushing was that it would have happened,
if they'd wanted it to. If they'd put it in "text-", all the better. I
fully agree that in the long run, it should not have been a part of
Subversion.
However, with me behind the keyboard, pushing, it just won't happen. And
if some folks I know cared to decide something, that standard would have
the chance of a snowball in hell. As far as I'm concerned, the idea is
as dead as the proverbial doorknob unless someone else picks it up.

I agree with Erik that this doesn't really belong in Subversion.
However, storing information like tab width in properties is a reasonable idea.
One suggestion is that some folks decide to get together and come up with a
standard set of properties with a common prefix (say, "text-") with common
meaning, and try to spread that standard. But it doesn't need to be part of
Subversion itself.

emacs and vi already have support to detect in-file tab size comments.
That's exactly what Kenneth was referring to. Why can't Ankh extract
exactly this information from the file content?

Then why does this work great for both vi and emacs?!

Right. Neither will 'svn cat' or 'svn diff'... They will just print
the tab character to the console.

'svn diff' doesn't interpret the file content. I agree that if Ankh
and TSVN adopt that the windows world would be largely covered, but
how would we make Subversion on linux behave like Subversion on
Windows?
No, the Subversion team made an explicit choice not to interpret file
content, because it leads to more problems than solutions... I think
it's a good idea to keep it that way. BTW: why couldn't Ankh and TSVN
agree on a 'separate file' solution? Or why can't they agree on the
same property?

Although I do see the benefit, I see hardly any relation to version control...
bye,
Erik.

No, agreed, Subversion doesn't do that. However at least the tab-size is
a part of the file's rendering, i.e. a part of the file's properties
which should be stored and versioned.

No, they would use the plug-ins: Ankh for VS, something for emacs etc.
Those two would cover a large part of the users.

Very nice... in theory. However, in real life that would imply yet
another hopelessly ignored library.
In real life, "cat" on linux and "type" on windows will never use any
solution to detect tab-size, whether it be a separate file or version
control system.
No, this property is for coders using the Subversion flavoured tools.
There is a real chance that if Subversion describes this property, the
tools and utilities can pick it up quite fast. For example, svn diff
could lead the way. If TortoiseSVN and Ankh adopt, the Windows world is
largely covered.
But, the separate file solution could gain ground IFF the Subversion
team would implement such a stand-alone library for all platforms. And
use it themselves, of course. Adopting a third party solution might also
work, if done officially by the Subversion team.

I question putting them in the "svn:" namespace, since Subversion isn't
directly involved in the editing of text files.
Some editors recognize this kind of control in the form of special source
code comments. Moving this information to Subversion properties would mean
that editors would need to link the Subversion libraries to access them.
Instead, I would suggest putting source style information in a separate
file so that users of any version control system could access it.
