Template documentation[view] [edit] [history] [purge]

 Usage

The template looks for a text-direction image that matches the directionality provided in the template call. It also provides standard abbreviations or descriptions for the given directionality.

• {{Script directionality|direction|historic=direction|traditional=direction|modern=direction|DirText|LableText|size=?px}}

 Values for Direction field

Direction and the named fields traditional, historic, or modern, should be one of the following values:

Text Directions		Input codes (case insensitive) and associated graphic
Word:	Line:	Down	Up	Left	Right	Alternate codes (matches * code)
Right-to-left		RL-TB *	RL-BT	–	–	RTL, R2L, right-to-left, or leftwards
Left-to-right		LR-TB *	LR-BT	–	–	LTR, L2R, left-to-right, or rightwards
Top-to-bottom		–	–	TB-RL *	TB-LR	Vertical
Bottom-to-top		–	–	BT-RL	BT-LR
Boustrophedon (RL,LR)		RLR-TB *	RLR-BT	–	–	Boustrophedon
Boustrophedon (LR,RL)		LRL-TB	LRL-BT	–	–
Vertical boustrophedon (TB,BT)		–	–	TBT-RL	TBT-LR
Vertical boustrophedon (BT,TB)		–	–	BTB-RL	BTB-LR
Variable direction		H-TB	H-BT	V-RL	V-LR
		Swirls
		Outwards		Inwards		Alternate codes (matches * code)
Clockwise		Ck-Out *		Ck-In *		CW-Out, and CW-In
Withershins		WS-Out *		WS-In *		AC-Out or CC-Out, and AC-In or CC-In
		Other codes and display
Other		Up-Right-Down: BTRB
Unsupported (ex. "Wave")		? Wave

* Codes marked with an asterisk have alternate codes, displayed in the last column.

• Note that many of the alternate codes resolve to the most common writing directions, and may not be universally applicable (eg, not all vertical writing systems are written Top to Bottom, in lines from Right to Left).

 Values for DirText and LabelText fields

DirText and LabelText can take one of the standard values or user-defined text:

Style	direction	DirText produces	Script directionality|historic=LTR	LabelText produces	Script directionality|traditional=LTR	LabelText produces	Script directionality|modern=LTR	LabelText produces
Full	{{Script directionality|LTR|full}}	Left-to-Right, down the page	||none|full	Historic:	||none|full	Traditional:	||none|full	Modern:
Expanded	{{Script directionality|LTR|exp}}	Left-to-Right (down)	||none|exp	Historic:	||none|exp	Traditional:	||none|exp	Modern:
Short	{{Script directionality|LTR|short}}	LTR (down)	||none|short	(Hist)-	||none|short	(Trad)-	||none|short	(Mod)-
In-Line	{{Script directionality|LTR|words}}	left to right	||none|words	historically,	||none|words	traditionally,	||none|words	modern,
Default	{{Script directionality|LTR}}	LTR	||none|	Hist:	||none|	Trad:	||none|	Mod:
Custom	{{Script directionality|LTR|Your text}}	Your text	||none|Your text	Your text	||none|Your text	Your text	||none|Your text	Your text
Blank	{{Script directionality|LTR|none}}		||none|none		||none|none		||none|none
Multiples	{{Script directionality|RLR-TB|historic=LTR|modern=TB-LR|traditional=Ck-Out|words|words}} produces right-left, left-right, etc.,historically, left to right, traditionally, clockwise swirl, modern, top to bottom

• Note that only the Full and Expanded styles fully differentiate all writing directions.

 Size field

The size of the graphic can be controlled using the size field. Unlike direction and text, the size field must be explicitly called with "size=". Since the icons are square, the image size can be set to a one-dimensional pixel value that corresponds to both the width and height. The size parameter does not effect the "?" of undefined text directions, except size=0 (see below). The default value is size=20px, for use in running text.

Example: {{Script directionality|RLR-TB|full}} produces Boustrophedon (right-left, left-right), down the page

The size field can also be set to "0" (zero) or "0px" in order to render only the directional text. This will also blank the "?" of an undefined text direction.

Example: {{Script directionality|RTL|full}} produces Right-to-Left, down the page

 Historic, Traditional, and Modern fields

The fields historic, traditional, and modern can be used to generate multiple labeled directionalities in addition to a single unlabeled one. Historic, traditional, and modern take the same values as the direction field, above. A blank direction field should be included if the Values for DirText field and Values for LabelText field, above are used, as the first unlabeled field will not be interpreted as those fields. Unless the historic, traditional, and modern fields are defined, the third unlabeled field will not be interpreted.

Example: {{Script directionality|exp}} produces Trad: Bottom-Up (right), Mod: Left-to-Right (down)

 Templates and files used

The workhorse of this template is a dependent file, /core, and most alterations to the function of the template need to be made there.
