[phrp720]

New Plugin Type

• Added a new scripts plugin type to enable running third-party scripts. This includes the creation of ScriptConfig and Script structs, as well as the implementation of script execution logic. (models/script.go [1] plugins/script/plugin.go [2]

Configuration Files

• Updated the README.md to include the new scripts plugin and replaced the detailed workflow description with a link to the plugin workflow documentation. (README.md README.mdR30-R34)
• Added example configuration for the scripts plugin in aw-plugin-scripts.yaml. (config-examples/aw-plugin-scripts.yaml config-examples/aw-plugin-scripts.yamlR1-R8)
• Expanded the aw-plugin-filters.yaml configuration with additional filters for various categories such as Email, Programming, Image, Audio, Video, Social Media, and more. (config-examples/aw-plugin-filters.yaml config-examples/aw-plugin-filters.yamlR1-R209)

Code Refactoring

• Moved the contains function to a new utility package and updated its usage throughout the codebase. (plugins/filter/operations.go [1] [2] [3] util/util.go [4]
• Updated the RawName method in the filters plugin to use the constant FILTER from the models package. (plugins/filter/plugin.go plugins/filter/plugin.goL77-R82)

Plugin Initialization

• Modified the Initialize function to include the new scripts plugin. (plugins/manager.go plugins/manager.goR6-R14)

Utility Functions

• Added utility functions for checking if a file exists and if a slice contains a given string. (util/util.go util/util.goR1-R21)

These changes collectively enhance the functionality, configurability, and maintainability of the aw-sync-agent-plugins project.
