File systems are compared by value: same backend, working directory, and branch lineage. This mirrors the behavior expected by recursive AST comparisons.

hashCode

override fun hashCode(): Int

mkdirs

fun mkdirs(path: String)

Creates a directory at path (relative to the working directory, or absolute), including any missing parent directories.

relativePathTo

override fun relativePathTo(other: FileSystem): FsEntry?

Computes the relative path from this file system's workingDirectory to other's.

reroot

override fun reroot(workingDirectory: FsEntry?): FileSystem

Creates a new root FileSystem on the same backend, with the given workingDirectory and no branch lineage, so that isRoot holds for the result.

resolve

override fun resolve(path: String): FsEntry

Resolves a local file path, either absolutely or relatively from workingDirectory. This does not perform any check for file existence.

write

fun write(path: String, content: String)

Writes UTF-8 content to the file at path (relative to the working directory, or absolute), creating missing parent directories.

writeBytes

fun writeBytes(path: String, content: ByteArray)

Writes raw content bytes to the file at path (relative to the working directory, or absolute), creating missing parent directories.
