Variables in title when clicking "New Tiddler" button?

[Logan Chin]

Hi all,

I've spent the past couple days trying to optimize my wiki for when school starts.

I have created a "New Tiddler" button to press for each new lecture of a given class; I have designed it such that the requisite course tags/fields are filled every time a new tidier is created.

 I am wondering if there is some way to automate the date in the title of the tiddler? Or would it be possible to have a title such as "Lecture#(x)" in which every click increases x by 1? I have provided the code below:

<$button>

<$action-sendmessage $message="tm-new-tiddler"

   title=""

   tags= "[[IntrotoPolySci]]"

   year=<<now "YYYY">>

   month=<<now "MMM">>

   day=<<now "DD">>

/>

New Lecture

</$button>

Thanks!

Try this:

1) Create a tiddler called "NewLectureButton", containing:

\define addLecture()

<$vars num={{{ [prefix<currentTiddler>sort[modified]last[]split[Lecture #]rest[]else[0]add[1]] }}}>

<$vars newTitle={{{ [<currentTiddler>addsuffix[ Lecture #]addsuffix<num>] }}}>

<$set name="newTags" filter="[<currentTiddler>]">

<$action-sendmessage $message="tm-new-tiddler" title=<<newTitle>> tags=<<newTags>>

   year=<<now "YYYY">> month=<<now "MMM">> day=<<now "DD">>

/>

\end

<$button actions=<<addLecture>>>New Lecture</$button>

Then, to use it:

1) Create a tiddler with a given course title (e.g., "Basket Weaving 101")

2) Enter whatever text you like (e.g., a course description, professor's name, room #, etc.)

3) Include the following somewhere in the content:

{{||NewLectureButton}}

How it works:

* The NewLectureButton tiddler displays a button that triggers an "action macro" (addLecture) when pressed.  This macro performs the following steps:

* "$vars num=..." calculates the next lecture number:

** Find all tiddlers that start with the course name (prefix<currentTiddler>)

** Get the most recent one (sort[modified]last[])

** Remove everything except the last lecture number (split[Lecture #]rest[])

** If this is the first lecture, use default number (else[0])

** Add 1 to the last lecture number (add[1])

* "$vars newTitle=..." constructs the new title by adding " Lecture #n" to the end of the course name (i.e., the current tiddler title)

* "$set name=newTags..." constructs a new tag from the course name, allowing for spaces in the course name

* The action-sendmessage creates a new tiddler, opened for editing, using the calculated title, tags, year, month, and day

Let me know how it goes...

enjoy,

If you use actioncreate tIddler you can set a base title. If the tiddller already exists it increments a number in the title.

You can even retrive the title that was created.
