Hello,
After a long pause from TiddlyWiki, I came back to simplify my tool
(https://groups.google.com/d/msg/tiddlywiki/DiowJLeoJbw/igirhRHYAQAJ) of
creating solid links to tiddlers with the help of a "link button" in the
View Toolbar. The tool functions through the id field and it is really easy
to use.
a) If you want to create a link to the tiddler named *Present tiddler title*
(created
*20190208203055849*) AND having no "id" field value, just click the "link
button" in the View Toolbar of this tiddler. This will set the "id field"
to "*2019-02-08-Present tiddler title-22:30:55-849ms*" AND will copy *<<linkto
"2019-02-08-Present tiddler title-22:30:55-849ms">>* to clipboard. Now, you
can paste this macro into some other tiddler to get a a direct link to *Present
tiddler title*. If the id value would appear to be not unique (e.g., if you
clone a tiddler), the macro will provide the link to the oldest tiddler
which has the above mentioned id.
b) If "Present tiddler title" already HAS an id field value (assume it is
equal to *any_preferably_unique_id_591*), clicking the "link button" in the
View Toolbar will copy *<<linkto "any_preferably_unique_id_591">> *to
clipboard.
To try out the tool, create a tiddler (tagged with *$:/tags/Macro* and
*$:/tags/ViewToolbar*) with the following body text:
\define linkto(idvar1)
<$list filter="[field:id[$idvar1$]!has[draft.of]limit[1]]"/>
\end
\define linkto2(idvar)
<<linkto "$idvar$">>
\end
\define id_value() $(cr_date)$-$(curr_title)$-$(cr_time)$-$(cr_msec)$ms
\define link_via_id(check_id, copy_id, if_no_id)
<$list filter="$check_id$ +[limit[1]]" name=act emptyMessage=<<$if_no_id$>>>
<<$copy_id$>>
</$list>
\end
\define copy_id()
<$action-sendmessage $message="tm-copy-to-clipboard" $param=<<linkto2
"$(idvar)$">>/>
\end
\define if_no_id()
<$action-setfield $tiddler=<<currentTiddler>> id=<<id_value>>/>
<$action-sendmessage $message="tm-copy-to-clipboard" $param=<<linkto2
"$(id_value)$">>/>
\end
<$button tooltip="Set id (if no id field exists) & copy a link" aria-label="Set
id (if no id field exists) & copy a link" class=<<tv-config-toolbar-class>>>
<$wikify name=cr_date text='<$view tiddler=<<currentTiddler>>
field="created" format="date" template="YYYY-0MM-0DD"/>'>
<$wikify name=cr_time text='<$view tiddler=<<currentTiddler>>
field="created" format="date" template="0hh:0mm:0ss"/>'>
<$wikify name=cr_msec text='<$view tiddler=<<currentTiddler>>
field="created" format="date" template="XXX"/>'>
<$set name="curr_title" tiddler=<<currentTiddler>> field="title">
<$set name="idvar" tiddler=<<currentTiddler>> field="id">
<<link_via_id "[title[$(currentTiddler)$]has[id]]" copy_id if_no_id>>
</$set>
</$set>
</$wikify>
</$wikify>
</$wikify>
{{$:/core/images/link}}
</$button>
You can provide this tiddler with the following fields:
caption: *{{$:/core/images/link}} (Set id) & copy a link*
description: *Set the id field (if it does not exist) of this tiddler and
copy a link to clipboard*
By the way, I don't know how to make the caption show up, as long as the
"link button" is put under *More actions* in the View Toolbar..
