/* Primo VE HathiTrust Availability Add-On for CARLI I-Share - 12/15/2020
* adapted from https://github.com/UMNLibraries/primo-explore-hathitrust-availability
*
* NOTE: Be sure to add 'hathiTrustAvailability' to the
* angular.module() function at the top of the custom.js file,
* i.e., add it to the array that also includes 'angularLoad', e.g.:
*
* var app = angular.module('viewCustom', ['angularLoad', 'hathiTrustAvailability']);
*
* There are several optional configuration choices you can set for the app.component "template":
*
* Customizing the Availability Message - The default availability message that displays in the Brief
* Results list and the Full Record page is "Full Text Available at HathiTrust". You can override
* this by setting the msg attribute:
*
*
*
* Selectively Suppress Full-text Links - By default, the component will display full-text links
* for any resource.
*
* --If you want it avoid looking for full-text availability on records for which you already have online
* access, add the hide-online attribute to the component:
*
*
*
* --You can also suppress full-text links for journals, if desired, with hide-if-journal option:
*
*
*
* Copyright Status - By default, the component will display only when the item is out of copyright
* and therefore should be accessible.
*
* --If you want to display full-text links to any HathiTrust record, regardless of copyright status,
* use the ignore-copyright attribute:
*
*
*
* --If your institution is a HathiTrust partner institution and you want the availability links
* in Primo VE to use HathiTrust's automatic login process, add your SAML IdP's entity ID:
*
*
*
* E.g.,
* app.component('prmSearchResultAvailabilityLineAfter', {
* template: ''
* });
*
