Editing Shim (computing) (section)

== Examples ==
* Web [[Polyfill (programming)|polyfill]]s implement newer [[web standard]]s using older standards and [[JavaScript]], if the newer standard is not available in a given [[web browser]].<ref name="speakingjs">{{cite book|title=Speaking JavaScript |url=http://speakingjs.com/ |author=Axel Rauschmayer |year=2014 |at=[http://speakingjs.com/es5/ch30.html#id1267739 Shims Versus Polyfills]}}</ref>
* Support of [[AppleTalk]] on [[Apple Macintosh|Macintosh]] computers, during the brief period in which [[Apple Computer]] supported the [[Open Transport]] networking system. Thousands of Mac programs were based on the AppleTalk protocol; to support these programs, AppleTalk was re-implemented as an OpenTransport "stack", and then re-implemented as an API shim on top of this new library.
* The [[Microsoft Windows]] Application Compatibility Toolkit (ACT) uses the term to mean [[backward compatibility|backward compatible]] libraries. Shims simulate the behavior of older versions of Windows for legacy applications that rely on incorrect or deprecated functionality, or correct the way in which poorly written applications call unchanged APIs, for example to fix [[Principle of least privilege|least-privileged user account (LUA)]] [[software bug|bug]]s.<ref>{{cite web|publisher=[[Microsoft]]|url=http://www.microsoft.com/downloads/details.aspx?FamilyID=24da89e9-b581-47b0-b45e-492dd6da2971&displaylang=en|title=Microsoft Application Compatibility Toolkit 5.0|accessdate=2008-06-24|date=2007-12-11}}</ref>
* bind.so is a shim library for [[Linux]] that allows any application, regardless of permissions, to bind to a listening socket or specify outgoing IP address.<ref>{{cite web|publisher=Daniel Ryde|url=http://www.ryde.net/code/bind.c.txt|title=Source code of bind.so|accessdate=2014-04-05|date=2010-01-09|archive-date=2014-03-30|archive-url=https://web.archive.org/web/20140330151653/http://www.ryde.net/code/bind.c.txt|url-status=dead}}</ref> It uses the [[LD_PRELOAD]] mechanism, which allows shims and other libraries to be loaded into any program.
* In the ''type tunnel'' pattern, a generic interface layer uses a family of shims to translate a heterogeneous set of types to a single primitive type used by an underlying API.<ref>{{Citation
