|Operating system||Mac OS X|
SIMBL (short for SIMple Bundle Loader, formerly Smart InputManager Bundle Loader, and pronounced like symbol or cymbal), is an application enhancement (InputManager bundle) loader for Mac OS X developed by Mike Solomon. It helps third-party developers modify and add functionality to applications developed with the Cocoa environment without access to the source code. SIMBL loads code via the InputManager system, which was developed to support foreign input methods. Plugins using SIMBL have advantages over normal InputManager modifications such as targeted code loading into specific applications. Designed for Solomon's PithHelmet, SIMBL is now used by other developers. The most popular use of SIMBL is to add functionality to the Apple Safari web browser which did not have an Apple-authorized plugin system until version 5 in 2010.
SIMBL is installed like any other InputManager.[clarification needed] As such, it is restricted to certain locations depending on the version of Mac OS X installed. In default installations, it is located in /Library/InputManagers. In versions of Mac OS X prior to Mac OS X Leopard, SIMBL could be installed per-user. In plugin installations, the SIMBL package is automatically installed. Since SIMBL injects code into running processes, buggy plugins can cause process- or even systemwide problems.
Plugins for SIMBL are Cocoa bundles that add various functionality to Cocoa applications. They can be placed by the user manually through Finder or by an installer to /Library/Application Support/SIMBL/Plugins. It may also be placed in the user-specific home directories.
Advantages over InputManager Plugins
SIMBL bundles may be disabled by removing the plugin and restarting the application. With normal InputManager hacks, the user must log out and log in. Also, the normal InputManager mechanism is loaded for all Cocoa applications, providing the possibility of incompatibility and unexpected application behavior. SIMBL only loads bundles for specific and identified applications.
Leopard restrictions on InputManager plugins mean their installation can only be done system-wide. SIMBL plugins may be installed per-user if SIMBL is installed system-wide.
SIMBL plugins must specify which versions of the application that they will run with; running a more recent version of the application with the plugin activated will cause an error dialog to appear. Like all unsupported hacks, the amount of work required to update a plugin depends on the size of the update.
