ExpandFileName does exactly that.
No. ExpandFilename does much more and less. It corrects \ and / to
path delim, expands a relative filename with the *current working
directory* (Get/SetCurrentDir) and it expands tilde '~' to $HOME under
Linux.
If you want only create an absolute path from a directory and a
relative path use:
AbsPath:=AppendPathDelim(BaseDir)+RelPath;
This can create a file like '/usr/../lib' or '/usr/./lib' or
'/usr//lib', which are all valid file names, just somewhat ugly.
To resolve '..', '.' and double path delims use TrimFilename:
AbsPath:=TrimFilename(BaseDir+PathDelim+RelPath);
The above three would result in '/usr/lib'.
To even resolve system specials like '~' and cut trailing path delim
use CleanAndExpandFilename:
AbsPath:=CleanAndExpandFilename(BaseDir+PathDelim+RelPath);
CleanAndExpandDirectory is like CleanAndExpandFilename but appends a
path delim if not already there.
If you even want to resolve symlinks or get the real file name (e.g.
OS X UTF8 normalization, case insensitive file systems) there are
functions for that too.
Thanks Mattias (& Michael)! What a wonderful explanation! That FExpand
function is a beast and I didn't study it properly. I will indeed start
using it.
Paul.
