Conversion between absolute and relative paths in Delphi
I'm trying to figure out how to get a file path based on an original web link. In my application, I have two values:
fRootDir: String = C:\Some Directory\My Web Site\
(Application directory)
fImgPath: String = ../Some Other Web Site/SomeImage.jpg
(From a web page)
Result needs to be: C:\Some Directory\Some Other Web Site\SomeImage.jpg
Notice the ../
in front of the image path. This could be many in a row like ../../../
which each ../
means go up a folder. The image SomeImage.jpg
is in fact a location at C:\Some Directory\Some Other Web Site\
.
Also note that web links use /
- which is not a problem to convert to \
. The problem is with noticing ..
and actually looking in the above directory for each.
Now I need to combine the two properties to result in a final path of where to find SomeImage.jpg
on the computer, based on the root and the image paths.
Even simpler:
const
RootFolder = 'D:\PerforceThuis\Marjan\Probeersels\StackOverflow';
RelativeFolder = '..\..\General\Plugins';
begin
WriteLn(ExpandFileName(IncludeTrailingBackSlash(RootFolder)+RelativeFolder));
Tested in D6. Outputs:
D:\PerforceThuis\Marjan\General\Plugins
