[tw5] Re: Broken Concat / Embedded Widget Calls / JSON Tiddler Filter
Hi Mark, Every language I've worked in (I know TW is not a language per se, although it does have many language-like features like loops, conditionals, references, substitution, and look-up) has first-class (i.e., usable anywhere and arbitrarily nestable) support for string manipulation and construction via non-macro functions like concat(), substr(), instr(), and length(). This thread is a good example of how hard it is to construct a longer arbitrary string with arbitrary variable values concatenated into it (ultimately, we couldn't concat complex strings past a certain length). This thread is a good example of how macro-based string manipulation with embedded single and double quotes doesn't scale to longer strings or exhibit easily predictable behavior.

[tw5] Re: Broken Concat / Embedded Widget Calls / JSON Tiddler Filter
I don't understand the "Lack of String Manipulation" either. Writing
filters or macros for these standard tools would not be that difficult. I
can only assume there is some philosophical reluctance. Perhaps because
filters are supposed to work on *Titles*, not *strings*, and changing a
Title's case, for instance, makes it into a new tiddler. But there are
already existing filters that break this premise, so ... dunno.

Seems like the quote delimiting is broken here, but I don't see the
issue. What's more, trying to close the <$macrocall> tag with /> seems to
be closing the <$set> macro as well.
And there are a few other permutations of the above, none of which
work. =/ Help welcome and thanks in advance!

[tw5] Re: Broken Concat / Embedded Widget Calls / JSON Tiddler Filter
To wrap this thread up, while I love TiddlyWiki and don't see myself
changing due to its elegance and flexibility, I also at times find aspects
of it (several underlying this thread) frustrating:
- Hard-to-Intuit / Understand Syntax / Parsing Rules: Do I reference
something in a given context with double braces ({{}})? Single braces ({})?
Double angle brackets (<<>>)? Single angle brackets (<>)? Dollar signs?
Parens and dollar signs? Or will the kind of reference I'm trying to make
not work at all in my current context? And how will some given wikitext /
macro call / string be mangled by TW? Who knows? I haven't really developed
a predictive mental model of TW's behavior in 6+ months of working with it.
- Lack of String Manipulation: I expect built-in ways to do string
concatenation, searching, and splitting that nest and work in most contexts
(e.g., not hand-crafted and unreliable macros).
- Limitations of Fields: It's hard to leverage the elegant database
structure of TW when field names are constrained by some arcane naming
constraints. (I realize not entirely TW's fault.)
- Lack of JSON Index Operator Parity with Fields: And, to wit, it's not
possible to fully move to JSON data-driven Tiddlers (instead of fields)
when filters have so much built-in field searching and sorting operator
support that isn't supported for indexes.
- Documentation and examples at https://tiddlywiki.com/ are often too
simple (e.g., operator examples rarely show complex / dynamic values
populated by fields and variables like we see in this thread, which is
where I usually need help) or too terse, i.e., the non-example doc pages
often have sentence-fragment like descriptions of an operator's purpose or
behavior.
That said, after all the help from Mark, I suspected that my filter string
concatenation might work better if I weren't trying to assemble it from
string literals in the wikitext (which is a bit counterintuitive from
traditional programming), so I made my filter string components into fields
that I could reference in my concat macro. This helped, although ultimately
TW would only process the first 2 of these and the oddly the last one had
to go back to being a literal:
<$wikify name=search text=<> >
<$list filter=<> >
In which search_prefix = [tag[data_page]search:text:literal["father": "
And search_middle = "]][tag[data_page]search:text:literal["mother": "
By the way, a more compact (although I suspect less performant) way to
accomplish this filter / search is via a regex search filter similar to
this:
[tag[data_page]search:text:regexp[(\"mother\")|(\"father\"): \"
{{!!parent_page}} \"]]
Ultimately, however, even though I have mostly solved the search problem in
this thread, I am finding JSON data tiddlers filter operators too limited
(e.g., no sorting) relative to the fairly robust field filter operators in
TW, so I'm changing back to a mostly field-driven data model (with the
exception of complex field names that refer to other Tiddlers, e.g., those
that must contain capital letters and spaces, which TW cannot persist as
field names).
However, the help has been much appreciated!

[tw5] Re: Broken Concat / Embedded Widget Calls / JSON Tiddler Filter
You can use wikitext (markup with angle brackets ("<<"), or curly braces
("{{") ) inside of widgets or other HTML tags like:
<$vars mine={{!!stuff}}>
However, AFAIK, you can't use wikitext links (square brackets) as widget
attributes.
You can't use wikitext inside of wikitext like
<> or like [[mylink|{{!!stuff}}]]
and you can't use widgets as attributes inside other widgets like
<$vars mine=<$view field="stuff/> />
Sometimes it's possible to use wikitext curly braces inside of wikitext
angle braces (macros) if you process the text through the Wikify widget,
but to be honest I just poke around at it until something works ;-)

I know I can nest widgets like

Thanks, Mark. I haven't tried subfilters. I'll experiment with that tonight. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.

There are different ways that you might expand it. This one looks for the
contents of parent_page as either mother or father. It takes advantage of
another new feature in 5.1.19 -- the subfilter operator.

\define concat(a b c d e f g h) $a$$b$$c$$d$$e$$f$$g$$h$
<$wikify name=fatherFilter text="""<>""" >
<$wikify name=motherFilter text="""<>""" >
Father search: <> Mother Search: <>
<$list filter="[subfilter] [subfilter]">
* list: {{!!title}}

I see. New problem: I now need to expand this filter to include both the "father" and "mother" JSON indexes (and later on do some sorting), but no matter how I apply the quotes it seems like <$wikify> is running out of steam when I try to append another run to this filter string. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.

I'm not sure what 'eat' means in these rules, but your example has managed
to get me to something working. Interestingly, I had experimented with
<$wikify> before posted, but it couldn't get it to work right either and
had assumed it was a dead-end. For those curious (I spent a few hours
searching and experimenting before posting), here's how Mark's solution
works for the example:
<$wikify name=search text=<> >
search: <>
<$list filter=<> >
* list: {{!!title}}
Output:
search: [tag[data_page]search:text:literal["father": "Kieran"]]
- list: Angie - Data
- list: Kyle - Data

[tw5] Re: Broken Concat / Embedded Widget Calls / JSON Tiddler Filter
Wow, I didn't realize search had changed so much. I really need to pay
attention to those release notes.
The five laws of concatenation, which I just made up:
Wikitext can't eat Wikitext
Wikitext can't eat Widgets
Widgets can't eat Widgets
Widgets CAN eat Wikitext.
Wikify can sometimes bend laws 1 through 3
The following version may be too distant from what you wanted, but might
serve as a start. It did work in my quick test:
\define ppfilter(pp) [tag[data_page]search:text:literal["father":
"{{!!parent_page}}"]]
<$wikify name=search text=<>>
Variable: <>
<$list filter=<> >
* Search Result: {{!!title}}
