TiddlyWiki Community Wiki

Formatters are stored as an array of objects, defined in config.formatters[]. The TiddlyWiki core's wikify() process loops through this array in order, testing the match pattern of each formatter, one at a time, until a match is found.

At startup, a formatter object is created that contains config.formatters, which is a set of rules about how to turn wiki syntax into HTML. The Formatter constructor collects these into formatter.formatters and their regular expression match strings into one long RegEx called formatter.formatterRegExp. The formatter object is returned by getParser() by default.

Some functions always use the global formatter object when creating their wikifiers: wikifyPlainText(), highlightify().

A particular formatter has a variable called termRegExp, which is the RegEx to match the end of a type of expression. In the table formatter, there are two terminators: rowTermRegExp and cellTermRegExp.
