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
Trivial wrapper around Array[Byte]
with sane equality and useful toString
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.
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
Simple enum with the possible filesystem objects a path can resolve to
A richer, more informative version of the stat object.
A richer, more informative version of the stat object.
Created using stat.full! filePath
Lets you pattern match strings with interpolated glob-variables
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
A set of permissions; can be converted easily to the rw-rwx-r-x form via
toString, or to the 0x777 form via toInt and the other way via
PermSet.fromString
/PermSet.fromInt
The different ways you can redirect input/output streams from a suprocess
Redirect the input/output directly to a file on disk
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.
Thrown when you try to read from a resource that doesn't exist.
Represents path to a resource on the java classpath.
Represents path to a resource on the java classpath.
Classloaders are tricky: http://stackoverflow.com/questions/12292926
Represents a possible root where classpath resources can be loaded from; either a ResourceRoot.ClassLoader or a ResourceRoot.Class.
Represents a possible root where classpath resources can be loaded from; either a ResourceRoot.ClassLoader or a ResourceRoot.Class. Resources loaded from classloaders are always loaded via their absolute path, while resources loaded via classes are always loaded relatively.
A source which is guaranteeds to provide a SeekableByteChannel
An implicit wrapper defining the things that can be "interpolated" directly into a subprocess call.
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
The result from doing an system stat
on a particular path.
The result from doing an system stat

Created via stat! filePath
.
If you want more information, use stat.full
Encapsulates one of the output streams from a subprocess and provides convenience methods for accessing it in a variety of forms
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
Convenience APIs around java.lang.Process and java.lang.ProcessBuilder:
Convenience APIs around java.lang.Process and java.lang.ProcessBuilder:
- os.proc.call provides a convenient wrapper for "function-like" processes that you invoke with some input, whose entire output you need, but otherwise do not have any intricate back-and-forth communication
- os.proc.stream provides a lower level API: rather than providing the output all at once, you pass in callbacks it invokes whenever there is a chunk of output received from the spawned process.
- os.proc(...) provides the lowest level API: an simple Scala API around java.lang.ProcessBuilder, that spawns a normal java.lang.Process for you to deal with. You can then interact with it normally through the standard stdin/stdout/stderr streams, using whatever protocol you want
Extractor to let you easily pattern match on os.Paths.
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)")) segment: String = "Workspace" filename: String = "Ammonite"
To break apart a path and extract various pieces of it.
Inherit the input/output stream from the current process
Pipe the input/output stream to the current process to be used via
java.lang.Process#{getInputStream,getOutputStream,getErrorStream}
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.
Checks if a file or folder exists at the given 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)
Get the owning group of the file/folder at the given path
Creates a hardlink between two paths
The user's home directory
Checks whether the given path is a directory
Checks whether the given path is a regular file
Checks whether the given path is a symbolic link
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
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
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.
Gets the mtime of the given file
Get the owner of the file/folder at the given path
Get the filesystem permissions of the file/folder at the given path
The current working directory for this process.
Reads the contents of a os.Path or other os.Source as a
java.lang.String
.
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
The root of the filesystem
Gets the size of the given file
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.
Creates a symbolic link between two paths
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.
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.
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.
