trait BasePath extends AnyRef
A path which is either an absolute Path, a relative RelPath, or a ResourcePath with shared APIs and implementations.
A path which is either an absolute Path, a relative RelPath, or a ResourcePath with shared APIs and implementations.
Most of the filesystem-independent path-manipulation logic that lets you splice paths together or navigate in and out of paths lives in this interface
trait BasePathImpl extends BasePath
case class CommandResult(command: Seq[String], exitCode: Int, chunks: Seq[Either[Bytes, Bytes]]) extends Product with Serializable
Contains the accumulated output for the invocation of a subprocess command.
Contains the accumulated output for the invocation of a subprocess command.
Apart from the exit code, the primary data-structure is a sequence of byte chunks, tagged with Left for stdout and Right for stderr. This is interleaved roughly in the order it was emitted by the subprocess, and reflects what a user would have see if the subprocess was run manually.
Derived from that, is the aggregate out and err StreamValues, wrapping stdout/stderr respectively, and providing convenient access to the aggregate output of each stream, as bytes or strings or lines.
sealed trait FilePath extends BasePath
Represents a value that is either an absolute Path or a relative RelPath, and can be constructed from a java.nio.file.Path or java.io.File
sealed trait FileType extends AnyRef
Simple enum with the possible filesystem objects a path can resolve to
type Generator[+T] = geny.Generator[T]
class GlobInterpolator extends AnyRef
Lets you pattern match strings with interpolated glob-variables
class Path extends FilePath with ReadablePath with BasePathImpl
An absolute path on the filesystem.
An absolute path on the filesystem. Note that the path is normalized and cannot contain any empty "", "." or ".." segments
trait PathChunk extends AnyRef
sealed trait PathConvertible[T] extends AnyRef
case class PermSet(value: Int) extends Product with Serializable
A set of permissions; can be converted easily to the rw-rwx-r-x form via toString, or to a set of PosixFilePermissions via toSet and the other way via PermSet.fromString/PermSet.fromSet
case class PosixStatInfo(owner: UserPrincipal, permissions: PermSet) extends Product with Serializable
trait ReadablePath extends AnyRef
class RelPath extends FilePath with BasePathImpl with SegmentedPath
A relative path on the filesystem.
A relative path on the filesystem. Note that the path is normalized and cannot contain any empty or ".". Parent ".." segments can only occur at the left-end of the path, and are collapsed into a single number ups.
trait SeekableSource extends Source
A source which is guaranteeds to provide a SeekableByteChannel
trait SegmentedPath extends BasePath
case class Shellable(value: Seq[String]) extends Product with Serializable
An implicit wrapper defining the things that can be "interpolated" directly into a subprocess call.
trait Source extends Writable
A source of bytes; must provide either an InputStream or a SeekableByteChannel to read from.
A source of bytes; must provide either an InputStream or a SeekableByteChannel to read from. Can be constructed implicitly from strings, byte arrays, inputstreams, channels or file paths
case class StatInfo(size: Long, mtime: FileTime, ctime: FileTime, atime: FileTime, fileType: FileType) extends Product with Serializable
The result from doing an system stat on a particular path.
The result from doing an system stat on a particular path.
Note: ctime is not same as ctime (Change Time) in stat, it is creation time maybe fall back to mtime if system not supported it.
Created via stat! filePath.
If you want more information, use stat.full
class SubPath extends FilePath with BasePathImpl with SegmentedPath
A relative path on the filesystem, without any .. or . segments
case class SubprocessException(result: CommandResult) extends Exception with Product with Serializable
Thrown when a shellout command results in a non-zero exit code.
Thrown when a shellout command results in a non-zero exit code.
Doesn't contain any additional information apart from the CommandResult that is normally returned, but ensures that failures in subprocesses happen loudly and won't get ignored unless intentionally caught
trait WritableLowPri extends AnyRef

Extractor to let you easily pattern match on os.Paths. Lets you do
```
@ val base/segment/filename = pwd
base: Path = Path(Vector("Users", "haoyi", "Dropbox (Personal)"))

object copy
Copy a file or folder from one path to another.
Copy a file or folder from one path to another. Recursively copies folders with all their contents. Errors out if the destination path already exists, or is within the source path.
object exists extends (Path) ⇒ Boolean
Checks if a file or folder exists at the given path.
object followLink extends (Path) ⇒ Option[Path]
Attempts to any symbolic links in the given path and return the canonical path.
Attempts to any symbolic links in the given path and return the canonical path. Returns None if the path cannot be resolved (i.e. some symbolic link in the given path is broken)
object group extends (Path) ⇒ GroupPrincipal
Get the owning group of the file/folder at the given path
object hardlink
Creates a hardlink between two paths
object isDir extends (Path) ⇒ Boolean
Checks whether the given path is a directory
Checks whether the given path is a directory
Returns false if the path does not exist
object isFile extends (Path) ⇒ Boolean
Checks whether the given path is a regular file
Checks whether the given path is a regular file
Returns false if the path does not exist
object isLink extends (Path) ⇒ Boolean
Checks whether the given path is a symbolic link
Checks whether the given path is a symbolic link
Returns false if the path does not exist
object list extends (Path) ⇒ IndexedSeq[Path]
Returns all the files and folders directly within the given folder.
Returns all the files and folders directly within the given folder. If the given path is not a folder, raises an error. Can be called with list.stream to return an iterator. To list files recursively, use walk
For convenience os.list sorts the entries in the folder before returning them. You can disable sorted by passing in the flag sort = false.
object makeDir extends (Path) ⇒ Unit
Create a single directory at the specified path.
Create a single directory at the specified path. Optionally takes in a PermSet to specify the filesystem permissions of the created directory.
Errors out if the directory already exists, or if the parent directory of the specified path does not exist. To automatically create enclosing directories and ignore the destination if it already exists, using os.makeDir.all
object move
Moves a file or folder from one path to another.
Moves a file or folder from one path to another. Errors out if the destination path already exists, or is within the source path.
object mtime extends (Path) ⇒ Long
Gets the mtime of the given file or directory
object owner extends (Path) ⇒ UserPrincipal
Get the owner of the file/folder at the given path
object perms extends (Path) ⇒ PermSet
Get the filesystem permissions of the file/folder at the given path
object read extends (ReadablePath) ⇒ String
Reads the contents of a os.Path or other os.Source as a java.lang.String.
Reads the contents of a os.Path or other os.Source as a java.lang.String. Defaults to reading the entire file as UTF-8, but you can also select a different charSet to use, and provide an offset/count to read from if the source supports seeking.
object readLink extends (Path) ⇒ FilePath
Reads the destination that the given symbolic link is pointed to
object remove extends (Path) ⇒ Boolean
Roughly equivalent to bash's rm -rf.
Roughly equivalent to bash's rm -rf. Deletes any files or folders in the target path, or does nothing if there aren't any
object size extends (Path) ⇒ Long
Gets the size of the given file or folder
Gets the size of the given file or folder
Throws an exception if the file or folder does not exist
When called on folders, returns the size of the folder metadata (i.e. the list of children names), and not the size of the folder's recursive contents. Use os.walk if you want to sum up the total size of a directory tree.
object stat extends (Path) ⇒ StatInfo
Reads in the basic filesystem metadata for the given file.
Reads in the basic filesystem metadata for the given file. By default follows symbolic links to read the metadata of whatever the link is pointing at; set followLinks = false to disable that and instead read the metadata of the symbolic link itself.
Throws an exception if the file or folder does not exist
object symlink
Creates a symbolic link between two paths
object temp
Alias for java.nio.file.Files.createTempFile and java.io.File.deleteOnExit.
Alias for java.nio.file.Files.createTempFile and java.io.File.deleteOnExit. Pass in deleteOnExit = false if you want the temp file to stick around.
object truncate
Truncate the given file to the given size.
Truncate the given file to the given size. If the file is smaller than the given size, does nothing.
object walk
Recursively walks the given folder and returns the paths of every file or folder within.
Recursively walks the given folder and returns the paths of every file or folder within.
You can pass in a skip callback to skip files or folders you are not interested in. This can avoid walking entire parts of the folder hierarchy, saving time as compared to filtering them after the fact.
By default, the paths are returned as a pre-order traversal: the enclosing folder is occurs first before any of it's contents. You can pass in preOrder = false to turn it into a post-order traversal, such that the enclosing folder occurs last after all it's contents.
os.walk returns but does not follow symlinks; pass in followLinks = true to override that behavior. You can also specify a maximum depth you wish to walk via the maxDepth parameter.
object write
Write some data to a file.
Write some data to a file. This can be a String, an Array[Byte], or a Seq[String] which is treated as consecutive lines. By default, this fails if a file already exists at the target location. Use write.over or write.append if you want to over-write it or add to what's already there.
