pyd and converting arrays of strings

[Laeeth Isharc via Digitalmars-d-learn]

Hi

I am using PyD with latest stable LDC on Arch Linux 64 bit.

I have various structures I am trying to wrap to pass to python.  
For example:

struct PlotLines
{
	KPDateTime[] start_dates;
	KPDateTime[] end_dates;
	double[] y;
	string[] colors;
	long[] weights;
	string[] styles;
}

import pyd.pyd;
extern(C) void PydMain()
{
def!(bokehDownload,PyName!"bokeh_download", BokehBars 
function(string,bool))();
def!(bokehCountdown,PyName!"bokeh_countdown",CanvasTable 
function(BokehBars,bool,bool))();
module_init();
wrap_struct!(BokehBars,Member!("dates"),Member!("opens"),Member!("highs"),Member!("lows"),Member!("closes"),Member!("volumes"),Member!("openinterests"));
wrap_struct!(KPDateTime,Member!"year",Member!"month",Member!"day",Member!"hour",Member!"minute",Member!"second");
wrap_struct!(CanvasTable,Member!"plot_title",Member!"x_label",Member!"y_label",Member!"annotations",Member!"lines",Member!"bars",Member!"studies",Member!"grid_sequence");
wrap_struct!(PlotLines,Member!"start_dates",Member!"end_dates",Member!"y",Member!"colors",Member!"weights",Member!"styles");
wrap_struct!(PlotStudy,Member!"title",Member!"dates",Member!"lines",Member!"overbought",Member!"oversold");
wrap_struct!(PlotAnnotations,Member!"directions",Member!"dates",Member!"y",Member!"weights",Member!"values",Member!"colors",Member!"styles");
}

PyD doesn't seem to want to wrap a string[] member:

/home/laeeth/anaconda/lib/python2.7/site-packages/pyd/infrastructure/pyd/make_object.d(773): 
Error: cannot implicitly convert expression (python_to_d(item))

Member!"colors", Member!"weights", Member!"styles")

Any thoughts on whether I am doing something wrong, and if it is 
a PyD problem, how to circumvent it?


Thanks.
