Module: TUI::Decorators::FileCallBehavior

Included in:
EditDecorator, ReadDecorator, WriteDecorator
Defined in:
lib/tui/decorators/base_decorator.rb

Overview

Client-side decorator layer for per-tool TUI rendering.

Mirrors the server’s Draper architecture but with a different specialization axis: server decorators are uniform per EVENT TYPE (tool_call, tool_result, message), while client decorators are unique per TOOL NAME (bash, read_file, web_get) — determining how each tool looks on screen.

The factory dispatches on the tool field in the structured data hash received from the server. Unknown tools fall back to generic rendering provided by this base class.

Shared rendering for file-related tool decorators (read, write, edit). Extracts the file path from input and displays it in the header line, making the target file immediately visible — like bash shows its command.

Examples:

Render a tool call

decorator = TUI::Decorators::BaseDecorator.for(data)
lines = decorator.render(tui)
