SignWriting General Interest

font

The font module contains functions for handing the font.

font

font.cssAppend

Function that appends font-face CSS for the Noto Sans SignWriting font for use with SignWriting in Unicode 8 (uni8) characters.

This font-face declaration will use a locally installed font if available. If not found, the font will be loaded from a content delivery network.

The list of local names is currently a work in progress. The font-face currently works for Windows and iOS. This CSS is duplicated in the src/font/index.css file.

font.cssAppend(dir: string)
Parameters
dir (string) an optional relative directory for font location
Example
font.cssAppend('./font/')

symbol

The symbol module contains regular expressions and functions for parsing and composing SignWriting in Unicode 8 (uni8) characters.

symbol

symbol.re

Object of regular expressions for symbol strings

{ base, fill, rotation, full }

symbol.re

Type: object

symbol.parse

Function to parse symbol string to object

symbol.parse(symbolString: string): object
Parameters
symbolString (string) a symbol string
Returns
object: elements of symbol string
Example
symbol.parse('𝠀')

return {
 'base': '𝠀',
 'fill': undefined,
 'rotation': undefined
}

symbol.compose

Function to compose symbol string from object

symbol.compose(symbolObject: object): string
Parameters
symbolObject (object) an object of symbol parts
Name Description
symbolObject.base string base character for symbol
symbolObject.fill string fill character for symbol
symbolObject.rotation string rotation character for symbol
Returns
string: symbol string
Example
symbol.compose({
 'base': '𝠀'
})

return '𝠀'

string

The string module contains regular expressions and functions for parsing and composing SignWriting in Unicode 8 (uni8) symbol strings.

string

string.re

Object of regular expressions for string of symbols

{ full }

string.re

Type: object

string.parse

Function to parse string of uni8 symbols to array

string.parse(uni8String: string): array
Parameters
uni8String (string) a string of uni8 symbols
Returns
array: array of uni8 symbols
Example
string.parse('𝠀𝠁')

return ['𝠀','𝠁']

string.compose

Function to compose uni8 string from array

string.compose(stringArray: array): string
Parameters
stringArray (array) an array of uni8 symbols
Returns
string: string of uni8 symbols
Example
string.compose(['𝠀','𝠁'])

return '𝠀𝠁'
