How not to render link title with Sitecore Glass Mapper

Question

I'm rendering Sitecore Link with this method of GlassMapper:

        <li>
            <%=GlassHtml.RenderLink(icon, x => x.Link, null, true, string.Empty) %>
        </li>

but don't want to display Link description in Editing mode,

so even if Link description is filled it will be rendered like this:

<a href='https://url.com' class='icon-facebook' target='_blank' ></a>

and not like this:

<a href='https://url.com' class='icon-facebook' target='_blank' >Link description</a>

So I wonder if GlassHtml.RenderLink can be override for such kind of purposes? Tnx

One of the options is to add blank space for contents if the page is in editing mode. It won`t make the link empty but it won't show it's description.

<% if (IsInEditingMode)
       { %>
      <li>
                <%=GlassHtml.RenderLink(icon, x => x.Link, isEditable: true, contents: " ") %>
            </li>
    <% } else {%>

          <li>
                <%=GlassHtml.RenderLink(icon, x => x.Link, null, true, string.Empty) %>
            </li>
    <%}%>

Another option is to write your own glass extension. (For more information on how to do something like this you can see this thread - Glass Mapper RenderLink link description - default text if empty)

Glass.Mapper is open source and you can see how render link actually works here:

https://github.com/mikeedwards83/Glass.Mapper/blob/master/Source/Glass.Mapper.Sc/GlassHtml.cs (The method starts on line 297).

To extend it you will need something like this

public virtual string RenderEmptyLinkInEditing<T>(T model, Expression<Func<T, object>> field, object attributes = null, bool isEditable = false, string contents = null)
        {
            NameValueCollection attrs = null;

            if (attributes is NameValueCollection)
            {
                attrs = attributes as NameValueCollection;
            }
            else
            {
                attrs = Utilities.GetPropertiesCollection(attributes, true);

            }

            var sb = new StringBuilder();
            var writer = new StringWriter(sb);

            RenderingResult result = null;
            if (IsInEditingMode && isEditable)
            {

                if (contents.IsNotNullOrEmpty())
                {
                    attrs.Add("haschildren", "true");
                }

                result = MakeEditable(
                    field,
                    null, 
                    model,  
                    attrs,
                    _context, SitecoreContext.Database, writer);

              //  if (contents.IsNotNullOrEmpty())
              //  {
              //      sb.Append(contents);
              //  }
            }
            else
            {
                result = BeginRenderLink(
                        field.Compile().Invoke(model) as Fields.Link, attrs, contents, writer
                    );
            }

            result.Dispose();
            writer.Flush();
            writer.Close();
            return sb.ToString();

        }
