Using the History List Macro

The HISTORY_LIST macro allows you to create a HTML table in e-mails that you send out from the Helpdesk containing the complete history of a workitem.

The following example, taken from the reference manual, shows how to create a simple table.

<TABLE>HISTORY_LIST[[<TD>$$workitem_version$$
</TD><TD>$$workitem_modified_on$$
</TD><TD>$$workitem_modified_by_worker_name$$</TD>]]</TABLE>

This table will contain the version number, the modification date and the name of the worker that modified the incident.

We can use the same format to output the comments:

<TABLE>HISTORY_LIST[[<TD>$$workitem_version$$</
TD><TD>$$workitem_modified_on$$</
TD><TD>$$workitem_comment$$</TD>]]</TABLE>

However, if this is used in an e-mail to the users, they will see all the comments added to the incident including ones which were set as not visible to guests. In order to remove these comments I came up with the following code:

<TABLE>
REGEX{{HISTORY_LIST[[<TR><TD TAG=$$workitem_comment_visible_to_guest$$>$$workitem_modified_on$$</TD></TR><TR><TD TAG=$$workitem_comment_visible_to_guest$$>$$workitem_comment$$</TD></TR>]]}}{{(<TR><TD TAG=0)(.*?)(</TR>)}}{{ }}
</TABLE>

Note: For the above to work the entire REGEX statement must be entered as a single line in the e-mail template.
