stream-format ( str style stream -- )
Factor handbook » Input and output » Formatted output » Formatted stream protocol

Next:

make-span-stream ( style stream -- stream' )

Vocabulary
io.styles

Inputs

str	a string
style	an assoc
stream	an output stream

Outputs
None

Generic word contract
Writes formatted text to the stream. If the stream does buffering, output may not be performed immediately; use stream-flush to force output.

The style assoc holds character style information. See Character styles.

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

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