good points. OK, I'll do the rwo lists imbicated. Yet, I cannot see why I
get exactly the same results in the two lists below.
<$set name="chrome" value="[tag[Chrome]]">
<$list
filter="[subfilter<chrome>lowercase[]sentencecase[]splitregexp[\W]!is[blank]addprefix[
* ]]"/>
</$set>
<$set name="chrome" value="[tag[Chrome]]">
<$list
filter="[tag[Chrome]lowercase[]sentencecase[]splitregexp[\W]!is[blank]addprefix[
* ]]"/>
</$set>
which is
* noteself * by * danielo * rodr * guez * savetiddlers * extension * for *
chrome * and * firefox * by * buggyj * Emergency * tiddler * export *
Saving * on * tiddlyspot * Saving * to * a * git * service * Saving * via *
a * minimal * ruby * server * Saving * via * webdav * Saving * with * the *
html5 * fallback * saver * Tiddlydrive * add * on * for * google * drive *
by * joshua * stubbs * Tiddlywiki * cloud * Timimi * webextension * and *
native * host * by * riz
And same with
<$set name="chrome" value="[tag[Chrome]]">
<$list
filter="[subfilter<chrome>lowercase[]sentencecase[]splitregexp[\W]!is[blank]first[]]"/>
</$set>
<$set name="chrome" value="[tag[Chrome]]">
<$list
filter="[tag[Chrome]lowercase[]sentencecase[]splitregexp[\W]!is[blank]first[]]"/>
</$set>
where the result is:
noteself
(from ~"noteself" by danielo rodríguez~)
What's the use of subfilter in real life? It seems such a strange beast.
I'm really confused. I wish there be an equivalent of map() found in
functional language. I thought subfilter was just that but visibly it is
not.
with map I would code:
<$set name="chrome" value="[tag[Chrome]]">
<$list
filter="[subfilter<chrome>lowercase[]sentencecase[]splitregexp[\W]!is[blank]first[]]"/>
</$set>
In fact, I'm perplex when reading the subfilter help and the examples don't
help me. In particular, I am at odds with the input and the parameter S. S
is said to be a filter expression. And the outpur is the selection of
titles returned from the subfilter S. Let's see.
in the complete filter below, what is the input and what is the parameter S?
[subfilter[one two three]addsuffix[!]]
input should be: every tiddlers (but system tiddlers).
S is <<one two three>> and so S is a collection of three tiddler titles.
The output of subfilter is S, right?
Although it does not seems so because [[one two three]addsuffix[!]] does
not produce the same result ("one two three!" instead of "one! two!
three!").
