edit_pattern
Change the current Strudel session pattern by writing new code, appending, inserting at a line, replacing text, or clearing the editor.
Instructions
Mutate the current session pattern. mode=write replaces the editor contents (default; mirrors the old write tool exactly, including optional pattern validation and auto_play). mode=append concatenates code after the current pattern with a newline. mode=insert places code at the given line position. mode=replace runs a single string-replace from search to replace. mode=clear empties the editor. Example: edit_pattern({ mode: "write", pattern: "s("bd")", auto_play: true }). For reading the editor without mutating it use get_pattern; for the on-disk pattern catalog use pattern_store.
