How could I activate a "read-only" mode over "http://" or "https://" automatically?

#1

What I really would like to happen is to have no sidebar, and toolbars when it is deployed to the webserver or host.

I wrote this code at the very bottom of the wiki file:

<!--~~ Raw markup for the bottom of the body section ~~-->
<div id="tta-read-only-mode"></div>
<script>
var readOnlySetting = window.location.href;
if (readOnlySetting.match("http://") || readOnlySetting.match("https://")) {
	var readOnlyStyles = "";
	readOnlyStyles += "<style>";
	readOnlyStyles += "span.tc-tiddler-controls,";
	readOnlyStyles += "div.tc-sidebar-scrollable {";
	readOnlyStyles += "display: none !important;";
	readOnlyStyles += "}";
	readOnlyStyles += "</style>";
	document.getElementById("tta-read-only-mode").innerHTML = readOnlyStyles;
}
</script>

I am wondering if there is a TiddlyWiki way of doing something like this.

How do i deactivate the default option to save in the personal desktop in chrome or Edge?

You can use conditional CSS that uses wikitext to control whether it is used or not.

Place your CSS in a stylesheet tiddler and wrap it in a list widget that checks the URL protocol from info tiddlers.

As already suggested by Saq, create a tiddler, tagged with $:/tags/Stylesheet, containing something like this:

<$list filter="[{$:/info/url/protocol}prefix[http]]">
   span.tc-tiddler-controls, div.tc-sidebar-scrollable { display: none; }
   .tc-story-river { padding-right:3em;margin-right:0; }
</$list>

Note that, in addition to hiding the .tc-tiddler-controls and .tc-sidebar-scrollable, you probably also want to adjust the .tc-story-river right margin and padding to use the space left behind by the now-hidden sidebar.

Also if you wanted a finer level control of what happens you could use startup actions to set various tiddlers and settings depending on the content of $:/info/url/protocol as above.
eg actionSetFieldWidgets

Yep, here’s an example : Read only TW — experiment for a read only wiki hosted on tiddlyhost
