Button that read tags from a field.

[vinvi...@gmail.com]

Hello,

I have a button to create a new tiddler.

With    \define TAGS() [[$(currentTiddler)$]] [[Tag 2]] [[Tag 3]],  I can tag the new tiddler.

\define BUTTON-NAME() Enter >

\define BUTTON-COLOR+SIZE() btn btn-link btn-sm

\define BUTTON-TEXT-COLOR() color:

\define TIDDLER-TITLE() $(currentTiddler)$ ENTER-SPECIFIC-HERE

\define TIDDLER-TAGS() [[$(currentTiddler)$]]

\define TIDDLER-TEMPLATE() {{||$(currentTiddler)$-SPECIFIC-TEMPLATE}}

<$button type="button" class=<<BUTTON-COLOR+SIZE>>>

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

title=<<TIDDLER-TITLE>>

text=<<TIDDLER-TEMPLATE>>

tags=<<TIDDLER-TAGS>>

/>

<span style=<<BUTTON-TEXT-COLOR>>><<BUTTON-NAME>></span>

</$button>

What I want is for the button to read the tags from a field;

tags={{!!tiddler-tag}}

My problem is that [[$(currentTiddler)$]] in a field doesn't work.

How do I make this work?

Thank you,

Hi,

Since the tags field is of the list type, you need to retrieve its content either directly from another list-typed field (that is list or tags), or indirectly by transforming the string content into a list.

In your example, you may achieve this by first setting a variable to a filter that converts the content of your tiddler-tag field into a list :

<$set name=mytags filter="[enlist{!!tiddler-tag}]">

<$action-sendmessage $message="tm-new-tiddler"
title=<<TIDDLER-TITLE>>
text=<<TIDDLER-TEMPLATE>>

tags=<<mytags>>/>

</$set>

Note the use of the enlist operator to transform a string into a list. 5.1.23 just introduced the enlist-input operator, which is handy in situations where your initial string comes from a previous filter expression.

Cheers,

Thank you Xavier,

Can you tell me how to paste this piece of code into the existing code? 

For some reason I am not getting it working.

Hi,

Sorry I overlooked the need to interpret the currentTiddler variable. In this situation, you need to read your field as a filter rather than a list. Two main ways of doing that:

1. Either you put your button code in a macro so that the $(currentTiddler)$ construct is actually replaced by the title of the current tiddler. Then you can use the subfilter operator, as in :
   \define mybutton()

1. 
   <$button type="button" class=<<BUTTON-COLOR+SIZE>>>
   

1. <$set name=mytags filter="[subfilter{!!tiddler-tag}]">

1. 
   <$action-sendmessage $message="tm-new-tiddler"
   title=<<TIDDLER-TITLE>>
   text=<<TIDDLER-TEMPLATE>>
   tags=<<mytags>>/>
   </$set>
   

1. <span style=<<BUTTON-TEXT-COLOR>>><<BUTTON-NAME>></span>
   </$button>
   

1. \end
   <<mybutton>>
2. Or you can just replace [[$(currentTiddler)$]] with [<currentTiddler>] in your field content.  Like so :
   <$set name=mytags filter="[subfilter{!!tiddler-tag}]">

1. 
   <$action-sendmessage $message="tm-new-tiddler"
   title=<<TIDDLER-TITLE>>
   text=<<TIDDLER-TEMPLATE>>
   tags=<<mytags>>/>
   </$set>

Cheers,
