multi spurt(IO() $path, |c)

The $path can be any object with an IO method that returns an IO::Path object. Calls IO::Path.spurt on the $path, forwarding any of the remaining arguments.

From type/IO/Path

method spurt(IO::Path:D: $data, :$enc, :$append, :$createonly)

Opens the path for writing, and writes all of the $data into it. File will be closed afterwards. Will fail if it cannot succeed for any reason. The $data can be any Cool type or any Blob type. Arguments are as follows:

• :$enc — character encoding of the data. Takes same values as :$enc in open. Defaults to utf8. Ignored if $data is a Blob.

• :$append — open the file in append mode, preserving existing contents, and appending data to the end of the file.

• :$createonly — fail if the file already exists.

From type/IO/Handle

See Original text in context

multi method spurt(IO::Handle:D: Blob $data, :$close = False)
multi method spurt(IO::Handle:D: Cool $data, :$close = False)

Writes all of the $data into the filehandle, closing it when finished, if $close is True. For Cool $data, will use the encoding the handle is set to use (open or IO::Handle.encoding).

Behavior for spurting a Cool when the handle is in binary mode or spurting a Blob when the handle is NOT in binary mode is undefined.
