-====== Changes in Zotero ​2.1 ======+<​html><​p id="​zotero-5-update-warning"​ style="​color:​ red; font-weight:​ bold">​We’re 
 +in the process of updating the documentation for 
 +<a href="​https://​www.zotero.org/​blog/​zotero-5-0">​Zotero ​5.0</​a>​. Some documentation 
 +may be outdated in the meantime. Thanks for your understanding.</​p></​html>​
  
-===== Changes to citation API ===== 
  
-With the introduction of citeproc-js,​ all Zotero.CSL APIs have been removed. Styles can be loaded in the usual way by accessing Zotero.Styles,​ but +See [[dev/client_coding/Changes in Zotero ​2.and Zotero ​Standalone]].
-developers should use Zotero.Style.csl to acquire a citeproc-js engine instance for citation formatting. <​code>​Zotero.Cite.makeFormattedBibliography(engine,​ format)</code> can be used to generate a fully-formatted bibliography.  +
- +
-===== Changes to interface-related code ===== +
- +
-Zotero as a tab and Zotero Standalone have required us to further abstract the interface layer. While the code for the interface has changed little, and most overlays should continue to work, as of the present Zotero trunk, plug-ins and add-ons should now overlay zoteroPane.xul instead of browser.xul or overlay.xul in chrome.manifest,​ e.g., using: +
- +
-<​code>​overlay chrome:​//​zotero/​content/​zoteroPane.xul chrome://​zotero-addon/​content/​overlay.xul</​code>​ +
- +
-===== Changes ​to translators ===== +
- +
-  * Several functions ​in Zotero.Utilities have been eliminated, as they were essential duplications of built-in JavaScript methods. +
- +
-  * Zotero.configure() ​and Zotero.displayOptions() no longer exist. Instead, translators should specify config and display options in the metadata block at the top of the translator, e.g. <​code>​{ +
- "​translatorID":"​32d59d2d-b65a-4da4-b0a3-bdd3cfb979e7",​ +
- [...] +
- "​configOptions":​{"​dataMode":"​rdf/​xml"​},​ +
- "​displayOptions":​{"​exportNotes":​true},​ +
- "​lastUpdated":"​2011-01-11 04:​31:​00"​ +
-}</​code>​ +
- +
-  * It is no longer necessary to specify "​dataMode":"​block"​ or "​dataMode":"​line"​. If Zotero.read() is passed a numeric value, it reads a specified number of bytes; otherwise, it reads a full line. +
- +
-  * Import and export translators now show determinate progress bars. By default, Zotero computes progress by the percentage of the file read for import, or the percentage of items retrieved using Zotero.nextItem() for export. Translators can override this by calling Zotero.setProgress(percentage) to set the percentage the progress bar displays, or Zotero.setProgress(null) to show an indeterminate indicator. +
- +
-===== Changes to translate interface ===== +
- +
-New code should create new instances of the translate interface using type-specific constructors,​ e.g., to create a web translator:​ +
- +
-<​code>​new Zotero.Translate.Web();</​code>​ +
- +
-===== Locate Engines ===== +
- +
-Zotero 2.1b6 and later support extensible locate engines. For further details, see [[Creating Locate Engines using OpenSearch]]. +
- +
-====== Changes for Zotero Connectors (not yet implemented) ====== +
- +
-===== Changes to translators ===== +
-Zotero Everywhere will soon allow translators to operate outside of Firefox/​XULRunner. Legacy translators can still run inside Zotero Standalone, but will require that Zotero Standalone is running to operate. This will require the following code changes: +
- +
-  * Firefox-specific JavaScript must be avoided. This includes +
-    * "for each" loops +
-    * array comprehensions +
-    * destructuring assignment +
-    * several other features +
- +
-  * Some E4X functionality may not be available, although as much as possible will be preserved. As of Zotero 2.1b6, Zotero also offers DOM XML interfaces to translators. +
-   +
-  * Zotero.Utilities.retrieveDocument() and Zotero.Utilities.retrieveSource() should be avoided if possible. There may be workarounds that allow these to operate outside of Firefox, but they will be extremely inefficient. Zotero.Utilities.processDocuments(),​ Zotero.Utilities.HTTP.doGet(),​ and Zotero.Utilities.HTTP.doPost() will continue to be available as alternatives. +
- +
-  * Translate.getTranslatorObject() should now be called with a callback function as an argument, which will receive the translator object when it is available. This is backwards compatible with Zotero 2.1b6 and later. +
- +
-  * Zotero.selectItems() should now be called with a callback function as an argument, which will receive the list of selected items when it is available. Translators may still use Zotero.selectItems() synchronously,​ but this will require that the first part of the translator be executed twice. This is backwards compatible with Zotero 2.1b6 and later.+
