make-block-stream ( style stream -- stream' )
Factor handbook » Input and output » Formatted output » Formatted stream protocol

Prev:	make-span-stream ( style stream -- stream' )
Next:	make-cell-stream ( style stream -- stream' )

Vocabulary
io.styles

Inputs

style	an assoc
stream	an output stream

Outputs

stream'

an output stream

Generic word contract
Creates an output stream which wraps stream and adds style on calls to stream-write and stream-format.

Unlike make-span-stream, this creates a new paragraph block in the output.

The style hashtable holds paragraph style information. See Paragraph styles.

Notes
Most code only works on one stream at a time and should instead use with-nesting; see Default input and output streams.

Errors
Throws an error if the I/O operation fails.
