filepath.ni

The filepath module returns a Module object. All documented functions are part of this returned object.

To use: import 'std/filepath'

cwd(): string

cwd returns the current working directory. This function may return an empty string if the working directory can’t be determined. This is not common but possible.

dir(path: string): string

dir returns the directory portion of a file path. Effectively, everything before the last directory separator. This function is the complement to basename.

basename(path: string): string

basename returns the file portion of a path. Effectively, everything after the last directory separator. This function is the complement to dir.

ext(path: string): string

ext returns the extension of a file. Effectively, everything after and including the last period. This function will return an empty string if the file doesn’t have an extension.

abs(path: string): string

abs returns path as an absolute filepath starting at the system root directory. This function may return an empty string if the current working directory cannot be determined. This is not common but possible on some systems.

join(paths…: string): string

join will concatenate all path parts and separate them with the system-specific directory separator.
