/** Read lines from the console, with input editing.
*
* <h3>Thread safety</h3>
* The <code>LineReader</code> implementations are not thread safe,
* thus you should not attempt to use a single reader in several threads.
* Any attempt to call one of the <code>readLine</code> call while one is
* already executing in a different thread will immediately result in an
* <code>IllegalStateException</code> being thrown. Other calls may lead to
* unknown behaviors. There is one exception though: users are allowed to call
* {@link #printAbove(String)} or {@link #printAbove(AttributedString)} at
* any time to allow text to be printed above the current prompt.
*
* <h3>Prompt strings</h3>
* It is traditional for an interactive console-based program
* to print a short prompt string to signal that the user is expected
* to type a command. JLine supports 3 kinds of prompt string:
* <ul>
* <li> The normal prompt at the start (left) of the initial line of a command.
* <li> An optional right prompt at the right border of the initial line.
* <li> A start (left) prompt for continuation lines. I.e. the lines
* after the first line of a multi-line command.
* </ul>
* <p>
* All of these are specified with prompt templates,
* which are similar to {@code printf} format strings,
* using the character {@code '%'} to indicate special functionality.
* </p>
* The pattern may include ANSI escapes.
* It may include these template markers:
* <dl>
* <dt>{@code %N}</dt>
* <dd>A line number. This is the sum of {@code getLineNumber()}
* and a counter starting with 1 for the first continuation line.
* </dd>
* <dt>{@code %M}</dt>
* <dd>A short word explaining what is "missing". This is supplied from
* the {@link EOFError#getMissing()} method, if provided.
* Defaults to an empty string.
* </dd>
* <dt>{@code %}<var>n</var>{@code P}<var>c</var></dt>
* <dd>Insert padding at this position, repeating the following
* character <var>c</var> as needed to bring the total prompt
* column width as specified by the digits <var>n</var>.
* </dd>
* <dt>{@code %P}<var>c</var></dt>
* <dd>As before, but use width from the initial prompt.
* </dd>
* <dt>{@code %%}</dt>
* <dd>A literal {@code '%'}.
* </dd>
* <dt><code>%{</code></dt><dt><code>%}</code></dt>
* <dd>Text between a <code>%{</code>...<code>%}</code> pair is printed as
* part of a prompt, but not interpreted by JLine
* (except that {@code '%'}-escapes are processed). The text is assumed
* to take zero columns (not move the cursor). If it changes the style,
* you're responsible for changing it back. Standard ANSI escape sequences
* do not need to be within a <code>%{</code>...<code>%}</code> pair
* (though can be) since JLine knows how to deal with them. However,
* these delimiters are needed for unusual non-standard escape sequences.
* </dd>
* </dl>
