I've two things I want to do:
1) I want to use the current date/time as part of a concatenated string for
a new tiddler title.
2) I want to use the value of a field from the host tiddler as part of a
concatentated string for a new tiddler title.
3) I want to use 1) and 2) at the same time for the same new tiddler.
E.g.:
A host tiddler has a field "projectnumber" and that tiddler also hosts a
transcluded tiddler "newProjectEntry". "newProjectEntry" holds <$button>
code to create a new tiddler. Clicking the newProjectEntry button from the
host tiddler is intended to generate a new tiddler with a title "2018-02-01
09:57:04, 12345, Project entry:" where:
1. "2018-02-01 09:57:04" is the value from <<now ...>> when the button
is clicked.
1. Issue 1: I can get a date/time string, but it is the date/time AT
THE TIME that tiddler "newProjectEntry" is rendered in the host tiddler,
not at the time the button was pressed.
2. Issue 2: Otherwise, I get the text string "<<now ...>>" instead of
the rendered version for <<now ...>>.
3. Issue 3. Or otherwise, I get the proper date/time, but am unable
to concatenate a looked-up project number.
2. "12345" is the value of host tiddler's projectnumber field.
1. Issue 1: I can get the host tidder's title ("<<storyTiddler>>"),
but the construct "<<storyTiddler!!projectnumber>>" doesn't seem to work.
3. "Project entry:" (and the other spaces and commas) are text literals.
1. No issues here. I've mostly had sufficient guidance on how to
concatenate things. So far. I think.
What I've written:
Tiddler 1 fields:
> Title:hostTiddler
> projectnumber:12345
> Text:{{newProjectEntryPB}}
>
Tiddler 2 fields:
> Title:newProjectEntryPB
> Text:\define projecttitle() $(todaynow)$, $(projectnum)$, Project entry:
>
> <$set name="todaynow" value=<<now "YYYY-0MM-0DD 0hh:0mm:0ss">>>
> <$set name="projectnum" value={{<<storyTiddler!!projectnumber>>}}>
>
> Need a new project entry? Click this button and a project tiddler will be
> created:
> <$button>
> New project entry
> <$action-sendmessage
> $message="tm-new-tiddler"
> title=<<projecttitle>>
> />
> </$button>
>
> </$set>
>
When the button is clicked from within hostTiddler, it generates a new
tiddler with the title:
2018-02-21 18:36:34, , Project entry:
1) Issue: The date/time is not current with the button press.
2) Issue: Unable to get the project number value from the host tiddler.
Thanks much for your help!
