How to set repeat at beginning of bar w/o stave's start/left barline

[nitzanrh]

I'm trying to achieve the following:
https://en.wikipedia.org/wiki/Repetition_(music)#/media/File:Au_clair_de_la_lune_repetition.png

ie have a left/start repeat sign but without having the stave's left/begin barline. Is this possible?

When i set the stave's begin barline to repeat (stave.setBegBarType(4)) it automatically adds a barline in the beginning of the stave (ie left side).

Cheers,
Nitzan

I don't see that in the image you linked. But I guess what you wrote is what you want to achieve.

Sorry, here is a decent screenshot :)

@nitzanrh could you provide the code and a screenshot of what you are actually getting?

Yup, here is a jsfiddle:
https://jsfiddle.net/j5asuce8/

code:

VF = Vex.Flow;

// Create an SVG renderer and attach it to the DIV element named "boo".
var div = document.getElementById("boo")
var renderer = new VF.Renderer(div, VF.Renderer.Backends.SVG);

// Configure the rendering context.
renderer.resize(500, 500);
var context = renderer.getContext();
context.setFont("Arial", 10, "").setBackgroundFillStyle("#eed");

// Create a stave of width 400 at position 10, 40 on the canvas.
var stave = new VF.Stave(10, 40, 400);
stave.setBegBarType(4)

// Add a clef and time signature.
stave.addClef("treble").addTimeSignature("4/4");

// Connect it to the rendering context and draw!
stave.setContext(context).draw();

@nitzanrh I have been reviewing issues and I realised that I missed this one. Thaks for the jsfiddle! It helped a lot.
The behaviour is hard coded:

      case BarlineType.REPEAT_BEGIN:
        // If the barline is shifted over (in front of clef/time/key)
        // Draw vertical bar at the beginning.
        this.drawRepeatBar(stave, this.x, true);
        if (stave.getX() !== this.x) {
          this.drawVerticalBar(stave, stave.getX());
        }
        break;

I could add a REPEAT_BEGIN_NONE removing the bar at the beginning:

      case BarlineType.REPEAT_BEGIN_NONE:
        this.drawRepeatBar(stave, this.x, true);
        break;

would that help? Please note that you would still get the repeat bar after the time signature and not before (as shown in the example you provide)

Hi @rvilarl, thanks for your reply :)
Yeah I believe that would help. Personally I find the name REPEAT_BEGIN_NONE slightly confusing, but as long as the documentation is clear then that shouldn't be a problem.

Regarding the time signature; personally I wouldn't cause any problems with my usage for Vexflow, however I think that if you follow the strict "rules" of music notation then the barlines should appear before the time signature.
