type: text/vnd.tiddlywiki
caption: resolvepath
The <<.def resolvepath>> [[macro|Macros]] takes a relative path and an absolute path. It interprets the former relative to the latter, and returns the absolute equivalent of the former.
Folders in the paths are delimited by `/`.
The special folder name `.` denotes the current folder, and `..` denotes the parent folder.
If the absolute path indicates a folder, it needs to end with `/`. Anything after the final `/` is treated as an arbitrary filename within the intended path, and is discarded.
If no absolute path is supplied, the relative path is returned unchanged, except that anything after the final `/` is discarded.
The return value is a path, but does <<.em not>> end with `/`.
!! Parameters
;source
: the relative path
;root
: the absolute path
