Develop Sublime Text Plugins

Build or change a Sublime Text package so that it runs on the plugin host its .python-version selects, edits text only inside a TextCommand, does slow work off the main thread and discards stale results, owns and releases everything a plugin load creates, exposes commands through resource files that resolve, and ships as a clean archive. Each card in the references gives the definition, Use when and Do not use when conditions, the cost it removes, verification, and a runnable example. Cards cite the Sublime Text API reference, API environments, porting guide, release notes up to build 4215, UnitTesting, and Package Control documentation; follow them instead of recalling API behavior.
