File Paths

In this challenge, you need to use the filepath package to perform various operations on file paths, such as constructing paths in a portable way, splitting a path into directory and file components, checking whether a path is absolute, finding the extension of a file, and finding a relative path between two paths.

Requirements

• Use Join to construct paths in a portable way.
• Use Dir and Base to split a path into directory and file components.
• Use IsAbs to check whether a path is absolute.
• Use Ext to find the extension of a file.
• Use TrimSuffix to remove the extension from a file name.
• Use Rel to find a relative path between two paths.

Example

$ go run file-paths.go
p: dir1/dir2/filename
dir1/filename
dir1/filename
Dir(p): dir1/dir2
Base(p): filename
false
true
.json
config
t/file
../c/t/file

Summary

The filepath package in Golang provides functions to work with file paths in a portable way. By using these functions, you can construct paths, split them into directory and file components, check whether they are absolute, find the extension of a file, and find a relative path between two paths.
