Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with TiddlyWiki Markup Language (TWML).

What does this basic TWML code do?
<$button message='tm-edit-tiddler' param='MyTiddler'>Edit MyTiddler
This code creates a button that, when clicked, opens the tiddler 'MyTiddler' in edit mode.
What will be the output of this TWML code?
<$list filter='[tag[Task]is[open]]'>
<$checkbox field='status' tag='$:/tags/Checkbox' />
This code will output a list of checkboxes for each tiddler tagged as 'Task' and is open. The status of each task can be toggled by checking or unchecking its corresponding checkbox.
What does this TWML code do in terms of array or collection manipulation?
<$list filter='[tag[Task]sort[title]]'>
This code filters all tiddlers with the tag 'Task' and sorts them by their title. It then displays the title of each tiddler in the sorted list.
What does this TWML code do in terms of threading or concurrency?
<$action-sendmessage $message='tm-save-all' />
Save All
This code creates a button that, when clicked, sends a 'tm-save-all' message. This message triggers the saving of all tiddlers, which can be seen as a form of concurrency in TiddlyWiki, as multiple save operations can happen simultaneously.
