Function

fs(path) creates a file system path object, providing read and write, copy, move, delete, directory traversal and path information reading capabilities around the path.

fs.binary	Read the binary content of the file.
fs.lines	Read text files line by line.
fs.write	Overwrite the content of the written file.
fs.atomic_write	Atomic replacement of content via temporary files in the same directory, rejecting conflicts as per old SHA-256.
fs.append	Append content to the end of the file.
fs.prepend	Write content to the beginning of the file.
fs.size	Read file or directory metadata size.
fs.rename	Rename the current path to the target path.

fs.filename	Returns the last-level name of the path minus the extension.
fs.extension	Returns the path extension.

Examples

Notes

The path parameter of fs() will be parsed by the VM according to the current source code directory and project root rules.

- Synchronization file operation time should be controlled in the resident web service hot path.
