ModalOptions.show property value is ignored

[DethAriel]

Based on documentation here, if [options]="{ show: true }" is provided, then the modal should be shown upon initalization.
But this value is not even checked anywhere in modal.component.ts.

So, the option does not work. But it is a really nice one, since it allows to handle modals with *ngIf statements instead of show() / hide()

Also, based on https://github.com/valor-software/ng2-bootstrap/blob/development/src/modal/modal-options.class.ts#L26 this option has not really been working ever

[DethAriel]

If anyone else is interested, it can be work-arounded like this:

// place this somewhere, e.g. vendor.ts
import { ModalDirective, modalConfigDefaults } from 'ng2-bootstrap';

const nativeFn = ModalDirective.prototype.ngAfterViewInit;

modalConfigDefaults.show = false;
ModalDirective.prototype.ngAfterViewInit = function(this: ModalDirective) {
  nativeFn.apply(this, arguments);
  if (this.config.show) {
    this.show();
  }
}
