Variants§

§

NewLine

Signal that a new line should occur based on the printer settings.

§

Tab

Signal that a tab should occur based on the printer settings.

§

PossibleNewLine

Signal that the current location could be a newline when exceeding the line width.

§

SpaceOrNewLine

Signal that the current location should be a space, but could be a newline if exceeding the line width.

§

ExpectNewLine

Expect the next character to be a newline. If it’s not, force a newline.

§

QueueStartIndent

Queue a start indent to be set after the next written item.

§

StartIndent

Signal the start of a section that should be indented.

§

FinishIndent

Signal the end of a section that should be indented.

§

StartNewLineGroup

Signal the start of a group of print items that have a lower precedence for being broken up with a newline for exceeding the line width.

§

FinishNewLineGroup

Signal the end of a newline group.

§

SingleIndent

Signal that a single indent should occur based on the printer settings.

§

StartIgnoringIndent

Signal to the printer that it should stop using indentation.

§

FinishIgnoringIndent

Signal to the printer that it should start using indentation again.

§

StartForceNoNewLines

Signal to the printer that it shouldn’t print any new lines.

§

FinishForceNoNewLines

Signal to the printer that it should finish not printing any new lines.

§

SpaceIfNotTrailing

Signal that a space should occur if not trailing.
