Here's how you might get at the version history in JavaScript without getting involved with Java objects (but this isn't that pretty either).You can pick out other variables by adding them into the Freemarker template and then picking them out oft the split array when you buildyour object with versionRecord() .
// n is null (or undefined)
function isNull(n) { return ( n == undefined || n == null ) };
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Scrape Version History via Freemarker ~~
// date-time formats (Java)
const DT_ISO_8601 = 'yyyy-MM-dd\'T\'HH:mm:ss.SSS zzzzz' ;
const DT_RFC_1123 = 'dd MMM yyyy HH:mm:ss ZZZZZ' ;
const DT_GMT_8601 = 'yyyy-MM-dd\'T\'HH:mm:ss.SSS \'GMT\'ZZZZZ' ;
// To add:
// '<#setting datetime_format=\"' + DT_ISO_8601 + '\" >'
function vHistory( verLabel )
{ return (
'<#setting time_zone=\"UTC\" >'
+ '<#list document.versionHistory?sort_by("createdDate")?reverse as record>'
+(isNull(verLabel)? '' : '<#if record.versionLabel == \"' + verLabel + '\" >')
+ '${record.id}'
+'\\\\'+ '${record.nodeRef}'
+'\\\\'+ '${record.name}'
+'\\\\'+ '${record.type}'
+'\\\\'+ '${record.createdDate?string(\"' + DT_ISO_8601 + '\")}'
+'\\\\'+ '${record.creator}'
+'\\\\'+ '${record.versionLabel}'
+'\\\\'+ '${record.isMajorVersion?string(\'true\',\'false\')}'
+'\\\\'+ '${record.url}'
+'\\\\'+ '<#if record.description?exists>${record.description}</#if>'
+'\\\\'+ '${record.hasAspect("cm:versionable")?string(\'true\',\'false\')}'
+'\\\\'+
'${record.properties["cm:modified"]?string(\"' + DT_ISO_8601 + '\")}'
+'\\\\'+ '${record.properties.content.size?c}'
+ '\\%%\\'
+(isNull(verLabel)? '' : '<#break></#if>')
+ '</#list>' );
