autopair widget : inserting stray closers during copy/paste (multiline)

[Abdelilah-AIT-HAMOU]

When pasting multiline input (especially with quotes/brackets), autopair inserts matching closing delimiters across line breaks. Those auto-inserted closers end up on a separate line and are printed after
execution (e.g., “* ' } ] )”).

fixes #1563

@Abdelilah-AIT-HAMOU I need more information about your environment to properly fix this issue.

Questions

1. What terminal are you using? (e.g., iTerm2, Terminal.app, GNOME Terminal, Windows Terminal, etc.)

2. Does your terminal support bracketed paste mode?

   • Most modern terminals do, but some older ones don't
   • You can test this by running: printf '\e[?2004h' then pasting some text - if you see ^[[200~ before and ^[[201~ after the pasted text, bracketed paste is working

3. What application are you using JLine in? (e.g., JShell, Groovy shell, custom application, etc.)

4. Is Option.BRACKETED_PASTE enabled in your LineReader configuration?

Why This Matters

JLine has built-in support for bracketed paste mode. When it's working properly:

• The terminal sends ESC[200~ before pasted content
• JLine's beginPaste() method reads the entire paste at once
• The content is written directly to the buffer, bypassing autopair widgets
• So there should be no autopair problem

The fact that you're seeing this issue suggests bracketed paste is NOT working in your environment. This could be because:

• Your terminal doesn't support it
• It's disabled in the JLine configuration
• Something else is preventing it from functioning

Once I understand your environment better, I can provide an appropriate fix. The solution might be:

1. Enabling bracketed paste (if your terminal supports it)
2. Implementing a different detection mechanism (if bracketed paste isn't available)
3. Something else entirely

Thanks!

i saw you did some code changes !
do you still need me to answer these questions ?

1. What terminal are you using? :
   -> ITERM , MacOs terminal , ghosty

2- Does your terminal support bracketed paste mode?
yes

3. Is Option.BRACKETED_PASTE enabled in your LineReader configuration?
   YES

in my code i have :
.option(LineReader.Option.BRACKETED_PASTE, true)

the output example :
snippet i pasted to the console DECLARE l_text VARCHAR2(4000); BEGIN l_text := 'Single quotes '' '' , double quotes " ", parentheses ( ), braces { }, brackets [ ]'; dbms_output.put_line(l_text); END; /

what i'm getting as result :

SQL> DECLARE
         l_text VARCHAR2(4000);
     BEGIN
         l_text := 'Single quotes '' '' , double quotes " ", parentheses ( ), braces { }, brackets [ ]';
         dbms_output.put_line(l_text);
     END;
     / ] } )
```
notice the extra :  ] } ) at the end

Can you share a simple app to reproduce the problem ? I've been unable to find a way to actually reproduce the problem. Are you sure that a real terminal is created ? You can make sure of that by adding .dumb(false) to the TerminalBuilder before creating the Terminal.

this is what i have :

    terminal =
                            TerminalBuilder.builder()
                                    .encoding(StandardCharsets.UTF_8)
                                    .type(terminalChars.type)
                                    .system(true)
                                    .dumb(false)
                                    .exec(true)
                                    .paused(createPaused)
                                    .nativeSignals(false)
                                    .build();

                                    .nativeSignals(false)
                                    .build();

Thx, but this is only the terminal creation, and the issue is most probably not caused by that.
As an example that works, checkout this repository and run:

./mvx build
./mvx demo AutopairWidgetsExample

and paste your snippet containing braces and brackets...
