HepEventsIO class

In --output events the HEP stream owns stdout: streaming deltas (CliIO.write) are dropped — they ride message_delta frames — while diagnostics (CliIO.writeln: banners, tool traces, errors) keep flowing to the host's channel (stderr in headless mode).

Implemented types

Constructors

HepEventsIO(CliIO inner)

Wraps inner.

Properties

columns → int

Terminal width in columns. Non-TUI hosts use the 80-column default.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

inner → CliIO

final

interrupts → Stream<void>

Cancel signals (Ctrl-C). Each event aborts the current run.

no setter, override

isInteractive → bool

Whether a human is present to answer approval prompts (a real terminal, not piped input). When false, prompt-policy tool calls are denied with a reason — the safe non-interactive default.

no setter, override

keys → Stream<KeyEvent>

Raw key events when the terminal is in raw mode. Non-raw hosts (tests, headless, web) provide an empty stream.

no setter, override

lines → Stream<String>

User-typed input lines, without the trailing newline.

no setter, override

rows → int

Terminal height in rows. Non-TUI hosts use the 24-row default.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

supportsRawMode → bool

Whether the underlying terminal supports raw-mode character input with ANSI escape sequences. True for dart:io terminals; false for tests.

no setter, override

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

write(String text) → void

Writes text without a trailing newline (streaming deltas).

override

writeln(String text) → void

Writes text followed by a newline.

override

Operators

operator ==(Object other) → bool

The equality operator.
