path-exists bool(path string) global
true if anything (like a file or directory) exists at the path.

show string(a path-kind)
get-path-kind path-kind(path string) global
paths-in-dir string[](path string) global
Returns all children of the directory path, as full paths. Use names-in-dir instead if you want just the basenames.
names-in-dir string[](a string) global
Returns the basename of all children of the directory. Does not include ".." or ".". Use paths-in-dir instead if you want full paths.
read-link string(_ string) global
Gets the path a symbolic link refers to.
make-symlink-to void(link string, target string) global
Create a symbolic link at link with the target target.
current-executable-path string() global
Gets the path of the current executable. If this program was built to executable, this will return its path. Otherwise, this will be the path where keen is installed.
read-file string(path string) global
Reads the full contents of the file.
copy-file void(from string, to string) global
write-file void(path string, content string) global
Writes the full contents of the file as a string. If the file already exists, overwrites it.
write-file void(path string, content nat8[]) global
read-file nat8[](path string) global
current-directory string() global
Gets the current directory (of the user that ran the program).
each-child-recursive void(path string, f void mut(string)) global
If path is a directory, calls f on each file in the directory and any nested directories. If path is a file, calls f once.
each-child-recursive void(path string, filter bool mut(string), f void mut(string)) global
Like each-child-recursive, but calls filter on names of directory children and skips them if filter returns false.
