hello

```zig
/// run emun Function ex: combo
pub const FnEnum = enum {
	comboFn01,
	comboFn02,
	none,

	pub fn run(self: FnEnum, vpnl : *pnl.PANEL, vfld: *fld.FIELD ) void	{
		switch (self) {
			.comboFn01 => comboFn01(vpnl,vfld),
			.comboFn02 => comboFn02(vpnl,vfld),
			else => dsperr.errorForms(vpnl, Error.main_function_Enum_invalide),
		}
	}

	fn searchFn ( vtext: [] const u8 ) FnEnum {
	var i :usize = 0;
	const max :usize = @typeInfo(FnEnum).Enum.fields.len;
	while( i < max ) : (i += 1) {
		if ( std.mem.eql(u8, @tagName(@as(FnEnum,@enumFromInt(i))), vtext)) return @as(FnEnum,@enumFromInt(i));
		}
		return FnEnum.none;

	}
};
var callFunc: FnEnum = undefined;

```

error

```zig

I’ve seen `std.builtin.Type` fields being renamed to lowercase versions recently.

So try changing to this:

```zig
const max: usize = @typeInfo(FnEnum).@"enum".fields.len;

```

```zig
		inline for (@typeInfo(TaskEnum).@"enum".fields) |f| { 
				if ( std.mem.eql(u8, f.name , vtext) ) return @as(TaskEnum,@enumFromInt(f.value));
		}
		return TaskEnum.none;

```

Thanks, that solved 2 problems for me.
