file¶

type file < target: A file target represents a single file or directory in the filesystem. File targets are stored relative to the project root whenever possible, taking into account virtual mounts. They are automatically resolving to absolute paths when required.
fun file(Path: string, BuildFn?: any): file: Returns a new file target. If Path does not begin with /, it is considered relative to the current context path. If Path is specified as an absolute path but lies inside the project directory, it is converted into a relative path.
meth (File: file) % (Extension: string): file: Returns a new file target by replacing the extension of File with Extension.
meth (Target: file) - (Source: file): string | nil: Returns the relative path of Target in Source, or nil if Target is not contained in Source.
meth (Directory: file) / (Name: string): file: Returns a new file target at Directory/Name.
meth (Target: file):absolute: target | nil: Returns Target if is has an absolute path, otherwise returns nil.
meth (Target: file):basename: string: Returns the filename component of Target.
meth (Directory: file):chdir: file: Changes the current directory to Directory. Returns Directory.
meth (Source: file):copy(Dest: file): nil: Copies the contents of Source to Dest.
meth (Target: file):dir: file: Returns the directory containing Target.
meth (Target: file):dirname: string: Returns the directory containing Target as a string. Virtual mounts are not applied to the result (unlike Target:dir).
meth (Target: file):exists: file | nil: Returns Target if the file or directory exists or has a build function defined, otherwise returns nil.
meth (Target: file):extension: string: Returns the file extension of Target.
meth (Directory: file):ls(Pattern?: string|regex, Recursive?: method, Filter?: function, ...): list[target]: Returns a list of the contents of Directory. Passing :R results in a recursive list.
meth (Target: file):map(Source: file, Dest: file): file | error: Returns the relative path of Target in Source applied to Dest, or an error if Target is not contained in Source.
meth (Directory: file):mkdir: file: Creates the all directories in the path of Directory. Returns Directory.
meth (Target: file):open(Mode: string): stream: Opens the file at Target with mode Mode.
meth (Target: file):path: string: Returns the internal (possibly unresolved and relative to project root) path of Target.
meth (Target: file):relative: target | nil: Returns Target if is has a relative path, otherwise returns nil.
meth (Target: file):rmdir: file: Removes Target recursively. Returns Directory.
