ghidra.framework.plugintool.dialog.ExtensionUtils

public class ExtensionUtils
extends java.lang.Object

Utility class for managing Ghidra Extensions.

Extensions are defined as any archive or folder that contains an extension.properties file. This properties file can contain the following attributes:

• name (required)
• description
• author
• createdOn (format: mm/dd/yyyy)

Extensions may be installed/uninstalled by users at runtime, using the ExtensionTableProvider. Installation consists of unzipping the extension archive to an installation folder, currently Ghidra/Extensions. To uninstall, the unpacked folder is simply removed.

Returns a set of all extensions known to Ghidra, represented by ExtensionDetails objects. This will include all installed AND archived extensions.

Note that this method will only look in the known extension folder locations:

• ApplicationLayout.getExtensionArchiveDir()
• ApplicationLayout.getExtensionInstallationDir()

If users install extensions from other locations, the installed version of the extension will be known, but the source archive location will not be retained.

Returns:

list of unique extensions

Throws:

ExtensionException - if extensions cannot be retrieved

getInstalledExtensions

public static java.util.Set<ExtensionDetails> getInstalledExtensions(boolean includeUninstalled)
                                                              throws ExtensionException

Returns all installed extensions. These are all the extensions found in ApplicationLayout.getExtensionInstallationDir().

Parameters:

includeUninstalled - if true, include extensions that have been marked for removal

Returns:

set of installed extensions

Throws:

ExtensionException - if the extension details cannot be retrieved

getArchivedExtensions

public static java.util.Set<ExtensionDetails> getArchivedExtensions()
                                                             throws ExtensionException

Returns all archived extensions. These are all the extensions found in ApplicationLayout.getExtensionArchiveDir().

Returns:

set of archived extensions

Throws:

ExtensionException - if the extension details cannot be retrieved

isInstalled

public static boolean isInstalled(java.lang.String extensionName)

Returns true if an extension with the given name exists in the install folder.

Parameters:

extensionName - the name of the extension

Returns:

true if installed
