Helpers for working with the filesystem.

Page provides methods to interact with a single tab or extension background page in Chromium.

Transform a stream into a stream where each chunk is divided by a newline, be it \n or \r\n. \r can be enabled via the allowCR option.

Platform-specific conventions for the line ending format (i.e., the "end-of-line").

Make an assertion, error will be thrown if expr does not have truthy value.

Make an assertion that actual and expected are equal, deeply. If not deeply equal, then throw.

Make an assertion that actual is not null or undefined. If not then throw.

Make an assertion that actual match RegExp expected. If not then throw.

Make an assertion that actual not match RegExp expected. If match then throw.

Executes a function which returns a promise, expecting it to reject.

Make an assertion that actual matches a snapshot. If the snapshot and actual do not a match, then throw.

Make an assertion that actual includes expected. If not then throw.

Resolve a Promise after a given amount of milliseconds.

Copy a file or directory. The directory can have contents. Like cp -r. Requires the --allow-read and --allow-write flag.

Copy a file or directory. The directory can have contents. Like cp -r. Requires the --allow-read and --allow-write flag.

Detect the EOL character for string input. returns null if no newline.

Ensures that a directory is empty. Deletes directory contents if the directory is not empty. If the directory does not exist, it is created. The directory itself is not deleted. Requires the --allow-read and --allow-write flag.

Ensures that a directory is empty. Deletes directory contents if the directory is not empty. If the directory does not exist, it is created. The directory itself is not deleted. Requires the --allow-read and --allow-write flag.

Ensures that the directory exists. If the directory structure does not exist, it is created. Like mkdir -p. Requires the --allow-read and --allow-write flag.

Ensures that the directory exists. If the directory structure does not exist, it is created. Like mkdir -p. Requires the --allow-read and --allow-write flag.

Ensures that the file exists. If the file that is requested to be created is in directories that do not exist. these directories are created. If the file already exists, it is NOTMODIFIED. Requires the --allow-read and --allow-write flag.

Ensures that the file exists. If the file that is requested to be created is in directories that do not exist, these directories are created. If the file already exists, it is NOT MODIFIED. Requires the --allow-read and --allow-write flag.

Ensures that the hard link exists. If the directory structure does not exist, it is created.

Ensures that the hard link exists. If the directory structure does not exist, it is created.

Ensures that the link exists, and points to a valid file. If the directory structure does not exist, it is created.

Ensures that the link exists, and points to a valid file. If the directory structure does not exist, it is created.

Test whether or not the given path exists by checking with the file system. Please consider to check if the path is readable and either a file or a directory by providing additional options:

Expand the glob string from the specified root directory and yield each result as a WalkEntry object.

Synchronous version of expandGlob().

Format the file to the targeted EOL.

Moves a file or directory.

Moves a file or directory synchronously.

Walks the file tree rooted at root, yielding each file or directory in the tree filtered according to the given options.

Same as walk() but uses synchronous ops

Calls the given (possibly asynchronous) function up to maxAttempts times. Retries as long as the given function throws. If the attempts are exhausted, throws an RetryError with cause set to the inner exception.
