It is a very minor feature, but can be handy (it is in W++ template system Wink

.

CParser normally eats whitespaces after each token. I have now added GetSpacePtr that returns a pointer at the start of these whitespaces:

#include <Core/Core.h>

using namespace Upp;

CONSOLE_APP_MAIN
{
	CParser p("  someid     $$      and");
	LOG("GetPtr:      " << AsCString(p.GetPtr()));
	LOG("GetSpacePtr: " << AsCString(p.GetSpacePtr()));
	p.Id("someid");
	LOG("GetPtr:      " << AsCString(p.GetPtr()));
	LOG("GetSpacePtr: " << AsCString(p.GetSpacePtr()));
	p.Char('$');
	LOG("GetPtr:      " << AsCString(p.GetPtr()));
	LOG("GetSpacePtr: " << AsCString(p.GetSpacePtr()));
	p.Char('$');
	LOG("GetPtr:      " << AsCString(p.GetPtr()));
	LOG("GetSpacePtr: " << AsCString(p.GetSpacePtr()));
}

GetPtr:      "someid     $$      and"
GetSpacePtr: "  someid     $$      and"
GetPtr:      "$$      and"
GetSpacePtr: "     $$      and"
GetPtr:      "$      and"
GetSpacePtr: "$      and"
GetPtr:      "and"
GetSpacePtr: "      and"
