Can I invoke/execute a macro conditionally during Startup process?

[pimgeek]

I tried to use various methods( $list, $set, $reveal ), but all of them are failed ...

The follwing Tiddler had been tagged with $:/tags/StartupAction/PostRender

<$list variable="action" filter="[[$:/status/IsReadOnly]get[text]search-replace[yes],[hide-elements]]">
<$macrocall $name=<<action>> />
</$list>

Then I tried to use JS Macro, without success, either

(function(){

/*jslint node: true, browser: true */
/*global $tw: false */

"use strict";

exports.name = "reader-mode";

exports.params = [];
/*
Run the macro
*/
exports.run = function(act) {
  var isReadOnly = ""
  var statusTid = this.wiki.getTiddler("$:/status/IsReadOnly")
  if (statusTid) {
    isReadOnly = statusTid.getFieldString("text")
    if (isReadOnly == "yes") {
      return "readonly-hide-elements"
    }
  }
  return "unhide-elements"
};
})();

The follwing Tiddler had been tagged with $:/tags/StartupAction/PostRender

Hi,
Have a closer look at: https://tiddlywiki.com/#StartupActions

[pimgeek]

I have read this and written some simple js macros success fully, but that's much simpler date calc task -- https://wiki.hintsnet.com/#%2Fjsmacro%2Fday-diff.js:%24%3A%2FAdvancedSearch%20%2Fjsmacro%2Fday-diff.js%20%24%3A%2Fpimgeek%2Fstartup

[pmario]

JS macros have to have a header, that is needed by the startup mechanism, otherwise the macro won't be available

/*\
title: $:/plugin/your name/macros/readermode.js
type: application/javascript
module-type: macro

Your description of the macro 3-5 lines

\*/

/* your code comes here*/

How did you create the macro?

[pimgeek]

Would you have a look at this website？I want to hide some ui elements for anonymous visitors

https://wiki.hintsnet.com/#%24%3A%2Fpimgeek%2Fstartup:%24%3A%2FAdvancedSearch%20%24%3A%2Fpimgeek%2Fstartup

The tiddler $:/status/IsReadOnly is defined by the syncer, when it asks the server for the status info.
This communication is done after the rendering has already happened.

Have a closer look at the Network tab in the Dev-console.

As you can see. The tiddler doesn't exist at 1 Since it is created at 3

[pmario]

You may try to use the tiddler $:/status/IsReadOnly directly .. There may be some blinking, but it should work.

[pimgeek]

Thanks! Now I have a new plan, make every reader-related UI elements reveal / conceal according to the content of $:/status/IsReadOnly. ☺

[pmario]

So your js-macro does work, but the readOnly status tiddler doesn't exist, when it is executed.

This time my solution works!

/*\
title: $:/pimgeek/reader-mode.js
type: application/javascript
module-type: macro

\*/
(function(){

/*jslint node: true, browser: true */
/*global $tw: false */
"use strict";

/*
Information about this macro
*/
exports.name = "reader-mode";

exports.params = [];

/*
Run the macro
*/
exports.run = function() {
  function fb(err, isLoggedIn, username, isReadOnly, isAnonymous) {
    if (err){
      $tw.utils.warning(err)
    } else {
      $tw.wiki.addTiddler({ title: "$:/status/IsReadOnly", text: isReadOnly ? "yes": "no", "hidden": "$:/ControlPanel $:/core/ui/SideBar/More" })
    }
  }
  $tw.syncadaptor.getStatus(fb)
};

})();
