Property: Source
The apgExp object retains a copy of the input pattern in the source property.
Syntax
var exp = new apgExp(pattern);
Parameters
exp.source: Copy of pattern.

exp.sourceToHtml(): Returns source as HTML.
exp.sourceToHtmlPage(): Returns source as HTML, wrapped in a header and body for to make a complete HTML page..
Example 1
var pattern, exp;
pattern = 'word = alpha *(alpha / num)\n';
pattern += 'alpha = %d65-90 / %d97-122\n';
pattern += 'num = %d48-57\n';
exp = new apgExp(pattern);
console.log("source:");
console.log(exp.source);
/ * result */
source:
word = alpha *(alpha / num)
alpha = %d65-90 / %d97-122
num = %d48-57
Example 2
The sourceToText() function returns the pattern. It simply returns exp.source and is mostly for symmetry in the output functions./* same as Example 1 */
console.log("source:");
console.log(exp.sourceToText());
/ * result */
source:
word = alpha *(alpha / num)
alpha = %d65-90 / %d97-122
num = %d48-57
Example 3
exp.sourceToHtml() returns the pattern formatted as HTML. HTML characters, such as "<" and control characters are converted to entities and special display formats. The display page header should include the apgexp.css style sheet. e.g.<link rel="stylesheet" href="./apg-js/dist/apg-lib-bundle.css" type="text/css" />exp.sourceToHtml() returns the same, except wrapped in a complete page header and body.
/* same as Example 1 */
$("#this-page").html(exp.sourceToHtml());
/ * result */
word = alpha *(alpha / num)LF
alpha = %d65-90 / %d97-122LF
num = %d48-57LF
