Thread: [Rest2web-develop] Use of tilde as HOME indicator in paths

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

It would be good if ~ could be used inside paths through
os.path.expanduser(). Right now full paths have to be used.

Ok, but isn't a tilde also a valid part of a path name ? (I'm not Lunix 
user, so I don't know these things - but at least on Windoze it can be a 
valid part of a filename.)

Do you just mean (or particularly mean) in the config file ? How about 
if paths starting with a tilde were expanded ?

Yes, which under Windows could be expanded to C:\documentblah
blah\user or whatever it is.

os.path.expanduser() only expands the tilde as first character,
as any other implementation. Knowing this you can prefix a local
file with `./' if it starts with tilde, though right know the
other alternative is using full paths, which wouldn't allow tilde
expansion anyway.

I've just fixed this.

I now do 'expanduser' (~) expansion for the paths in the config file and the
'file' keyword in restindexes.

Anywhere else ?

In the macros, such as "colorize" ?

Ok, I'll fix the macros that take filenames.

In theory this should happen "everywhere", in a transparent way. What I
mean about transparent is that if you let users write '~/something' in a
configuration file, you can't write it back to disk as
'/home/user/something', since that may be or not the same username on a
different machine if I've copied that over the network to another
machine/account, or just happen to work on Linux and Macs, where the
paths are different.

Internally that's a pain, since you basically need to maintain the
enduser version and always expand it before using the filename. Sort of
the same goes for symlinks, where you can't go up the tree with "cd .."
because you may not end up in the place you expected.

I've always been tempted to use a special filename class which would
return the user specified string or the full real path name. This can be
handy when you get two paths and try to find out if you can build a
relative likn from one to the other.

As far as I *know* rest2web never writes back paths to configuration 
files or back into the restindexes.

As far as I know it also now expands tilde in all the relevant places. 
If you find any I've missed let me know.
