Module●Since v0.1
tool_display
Formatting utilities for tool call display in the app.
This module handles rendering tool calls and tool messages for the TUI.
Imported at module level by textual_adapter (itself deferred from the startup
path). Heavy SDK dependencies (e.g., backends) are deferred to function bodies.
Attributes
attributeattribute
MAX_ARG_LENGTH: int
Character limit for tool argument values in the UI.
Longer values are truncated with an ellipsis by truncate_value
in tool_display.
JS_EVAL_HEADER_MAX_LENGTH: int
Width at which the js_eval header truncates the first code line.
Shared with messages.py so the "header truncates the first line" cutoff and
the "offer a collapsible code block" threshold stay in lock-step from a single
source of truth.
Functions

get_glyphs
Get the glyph set for the current charset mode.

Remove known dangerous/invisible Unicode characters from text.
truncate_value
Truncate a string value if it exceeds max_length.
format_tool_display
Format tool calls for display with tool-specific smart formatting.
