Hello.
Is there any code in the tree that does general path transformation
or 'optimisation'?
For example, this path corresponds to the current working directory:
"dir1/dir2/dir3/../../../"
So I'd like to be able to pass that to a function and get the optimised
result of:
"."
And so on for paths such as:
"dir1/dir2/dir3/../../../../"
(Which obviously becomes "..").
"dir1/dir2/dir3/../../../dir1"
(Optimised to "dir1").
"dir1/dir2/dir3/../../../dir1/file.txt"
("dir1/file.txt")
It's giving me a real headache trying to work out the algorithm
to do this.
thanks,
MC
