Here's some code that runs in the prerelease 5.1.20 (it needs the new 
operators).

ABSOLUTELY make sure you have a copy of everything in your browser and in 
your desktop, because if you have a lot of tiddlers, this may crash your 
browser. You may get a lot of those "A script on this page is slowing down 
your web page messages.". If so, just keep clicking on "wait". It should 
finish eventually.

The reason this is so slow is because the nsort won't work on a tiddler 
with the title "552 My tiddler" as a number (552). So what I did instead 
was to first find all the counts and sort them, and then match those counts 
against each tiddler. Crazy inefficient. 

For your safety, there is limit[10] in the output filter. Remove this from 
the filter when you're ready to try it for read.

Currently this will show you the count of all standard tiddlers, including 
image tiddlers. The image tiddlers are likely to be your biggest.

Have fun, and be careful. But not in that order.


\define numbered-tiddlers()
<$vars pre="" suf="" mid=".0 ">
<$list filter="[all[tiddlers]!is[system]]" variable="tid">
<$list filter="[get[text]length[]]" variable="count">
<$list filter="[]"/>



\end
\define find-tiddlers-by-number(num)
$num$
<$vars pre="" suf="" mid=".0 ">
<$list filter="[all[tiddlers]!is[system]]" variable="tid">
<$list filter="[get[text]length[]regexp[^$num$$]sort[]]" 
variable="tid2">
$num$ == <$link to=<>><>



\end


<$wikify text=<> name="sortus" mode="inline">
<$list filter="[enlistnsort[title]limit[10]]" variable="cnt">
<$macrocall $name="find-tiddlers-by-number" num=<>/>


<$wikify text=<> name="sortus" mode="inline">
<$list filter="[enlistnsort[title]]" variable="cnt">

[tw5] Re: Styling and sizing images as buttons

Folks,

I am bumping this request hoping someone can help. So far I have spent some 
hours trying to ensure I never spend hours again. :(

The following is the best I hacve so far

{{$:/core/images/timestamp-on}}



{{$:/favicon.ico}}




{{Motovun Jack.jpg}}





{{$:/PSaT/buttons/archive/add.png}}




{{$:/PSaT/buttons/archive/archive.svg}}

However the first and last two fail because it only ever displays the size 
set inside the the SVG tiddler.

I would like to find a way that works with all image types consistently and 
if not create a macro that will handle what ever image tiddler it is given 
and set a given height and/or width.
A macro that can replace the customary transclusion of the image tiddler 
such that we can also say 
<>
etc

Any css or svg experts here?

Regards
Tony

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

Josiah,

My answer to your question is

Should you need to as a workaround

However depending on how the tiddlers are to be used it may provide additional 
functionality.

More directly the problem at hand its suggested it relates to skinny tiddler 
handling. A feature one may want everyday but which tests resources in large 
batches. If its a code bug we fix it, if its external in node perhaps simply a 
short or configurable pause every 1000 tiddlers could be sufficient.

Regards
Tony

[tw5] Re: How does one use Bricks?

2019-06-04 Thread Thomas Elmiger

Hello again, passingby,

Sorry for my late reply, but I am drowning in work and need some time for
family and friends too ... so I will keep it short this time:

https://tid.li/tw5/test/bricks.html was left in a messy state some time
ago. Sorry again. Now I brought the most important documentation tiddlers
to the front again, so I hope it will make a much more friendly entry point
again. I have tried to explain, what is offered, so I hope reading
carefully and following the links will bring you closer to your goals.

Note: there might be differences between the docs and the actual state of
Bricks, so if you have questions or encounter errors, please ask, protest,
let me know!

The dark forces palette is there and can be activated with one click:
https://tid.li/tw5/test/bricks.html#%24%3A%2Fplugins%2Ftelmiger%2Fbricks%2Fpalettes

I hope you will be able to customize everything you want by searching for
the corresponding stylesheet in the Style Manager. Stylesheets from plugins
should also appear in the list of the manager.

When you are done, it might be sufficient to generate final stylesheets as
described in
https://tid.li/tw5/test/bricks.html#Wikilogic%20Tiddler%20Transformation
instead of creating a theme right away.

Please ask again, if you need help or encounter problems.

All the best,
Thomas

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

After lazing-loading the text data, I populated all the text fields. Then I 
deleted the text fields.

Outcome:

1. The tiddlers created have a different kind of line return then your test 
data (maybe \r\n vs \r ?) 
2. The tiddlers created have a line return after the last header line, 
adding one blank line on the end
3. The tiddlers can now be loaded without the lazy-load option.

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

I just realized something Jeremy said. This is happening because it's 
acting as if the tiddlers have been lazy-loaded when they actually 
haven't been.  So ... If you use the lazy-load option:

   root-tiddler=$:/core/save/lazy-all

then the Wiki will load fine without crashing. So if you really want to 
load this set, you can do so.

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

Mark,

I am not sure the exact number matters much.
So far anyone who tried to reproduce it with 2000 tiddlers got the server 
to crash, so the issue is reproducible on most systems.
I would expect the exact number to differ depending on the available memory 
and processing power, but the gist of the problem is that the system cannot 
handle a few thousands of skinny tiddlers while being quite capable of 
handling tens of thousands of "normal" tiddlers.

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

I'm not sure what the "1800" tiddlers is based on. In my tests, all the 
tiddler titles loaded. Behind the scenes, apparently the server was stilll 
fishing for tiddler text. It must have been using an internal array to save 
results while waiting for (non-existent) data to load. The server crashed 
after the server had reported 1862 load attempts. But that's just as far as 
the reporting got. Internally, it may have had all the load events queued. 
The output reporting would have just lagged. So, I think,it would be more 
about machine processing maching. I'm running at 3.2 Ghz. I suspect solex's 
processing speed is similar.

The way I captured the report is to use the > operator to funnel the output 
of the node launch into a text file. Then I could look at the file and 
count how many load entries there were. solex could repeat the process with 
his own device. It would be a doubtful coincidence if our count was exactly 
the same. In that case, maybe there's a pre-set number of threads?

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

TonyM,

It has to be text. The crash occurs regardless of the number and the 
content of other fields.
If I understood Jeremy correctly, a tiddler with no text field is 
considered a "skinny tiddler" and is treated differently by the sync 
process, thus causing the memory overload when the number of such tiddlers 
is in thousands.

My impression reading the thread is that the "break-down" occurs at a 
specific point?

I mean, a server overload I can't see happening at a specific number on 
different machines. That has to be code?

I remain hazy whether this is able to be replicated at a set number? But 
that was my naive first impression--that it does?

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

Some

A question. Rather than adding newlines to text, adding nothing but actually 
something in each tiddler and thus defeating the possibility of using the 
filter [all[current]has[text]] to test if text has content.

Would populating a field in each tiddler do the same? or must it be the text 
field?

If you must use the text field perhaps insert something like "batch creation: 
batchname", then you could list items with a text field with prefix[batch 
creation:] or prefix[batch creation:batchname] if you needed to identify 
thousands for batch deletion.

Regards
Tony

[tw5] Quiz/Test

2019-06-04 Thread Chems

Hey,

I am starting to use Tiddlywiki to summarise school works. Now I had the 
idea, to include a Test/Quiz for myself.
I imagined something like this: My tiddlers are named after years e.g. 
1913. The first row is usually a few words summary, like: Start second 
World war.

Now, a test I imagined would show me the Year, and like 4 answer 
possibilities, from which one is correct. Like:
1913
Start Vietnam War
Jesus was born
Start second World war
G. Washington was elected

After choosing my answer, the correct answer would be marked and the next 
question starts.

I Hope you understand what I mean and you have a idea!

Thank you in advanced!

Re: [tw5] Re: File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

Hi Jeremy,

I just opened an issue on Github. Please feel free to close if you believe 
it's not a bug.

However, I do believe this needs to be at least documented. Currently there 
is no reason to expect this crash, and the cause of the problem is not 
immediately obvious.
Perhaps a note could be added somewhere that skinny tiddlers are treated 
somewhat differently by the system, and that one shouldn't create too many 
of them.
(If I knew that, for instance, I could have easily avoided the problem 
altogether by simply adding a few newline characters to my tiddlers)

Thanks

2019-06-04 Thread Jeremy Ruston

Hi Solex

This isn’t actually a bug, it’s more of an unexpected consequence of the way 
that lazy loading is implemented: in client-server mode, if the browser 
references a skinny tiddler (one that lacks a text field) then it requests the 
body from the server. It’ll only do it once for each tiddler but in a case like 
this with thousands of skinny tiddlers it looks like it can overload the server.

Best wishes

Jeremy.

[tw5] File-based TW on node.js crashes when the number of tiddlers without text field is more than ~1800

Hi,

I can confirm that the problem is related to text-less tiddlers (as PMario 
suggested). 
The problem can now be properly restated as: *File-based TW on node.js 
crashes when the number of tiddlers without text field is more than ~1800*
The number and structure of the rest of tiddlers doesn't matter, so long as 
a total number of text-less tiddlers is over the threshold.
The problem appears to be related to the "load" task dispatched by 
syncer-server-filesystem, because apparently this task is only dispatched 
for text-less tiddlers, but not for tiddlers with text.

This looks like a bug to me, because "title" is supposed to be the only 
required tiddler field, and also because the system fails in a non-obvious 
way (as opposed to, say, refusing to process tiddlers that don't meet 
certain requirements)

What is the proper way to submit a bug? Should I open a Github issue?

Thanks,

[tw5] Re: Count data dictionary values

Thanks for taking this further PMario! I'm only just getting to grips with data 
tiddlers but they seem to me to be similar to single column spreadsheets. They 
have an index and a single column of values, and each value 'slot' is similar 
to a spreadsheet's cell in just one column. 
If I create 2 or more data tiddlers with the same indexes then the number of 
value columns available to my 'spreadsheet' expands and 'cells' across both 
tiddlers can be referenced by {{distinctdatatiddlername##sharedindex}}.
In an ideal world I'd like to be able to sum those values but also to be able 
to carry out the other maths operations that a spreadsheet allows on individual 
values, ranges of values, groups of values that match a criteria etc - (i.e 
values filtered to meet a condition, across several data tiddlers).
I hope that makes some sort of sense. Just my 2 shrimps worth if you're 
thinking about formulating a pull request.

[tw5] Re: Count data dictionary values

Hi,

Working with data-tiddlers there is the "indexes" and the "getindex" 
operators. ... BUT they are not enough with the new math functions. 

As the OP shows. ... The new "values" operator works similar to the 
"indexes" operator, but it lists the values instead of the indexes (keys)

Since the both outputs are sorted, I also want to have an "keyvalues" 
operator, which will allow us to get both elements, and use string 
manipulation afterwards.

I think this is the existing "enlist" operator.

[tw5] easy basic question on listing references of a tiddler

2019-06-04 Thread steved

Sorry learning - but I could not find the syntax for calling the  
references of a tiddler 

I thought it might be 

{{{ [all[*References*]] }}} or [type[references]]

so what would I change to list the references
 
reference being the 

   - The *References* tab lists all the tiddlers that link *to* the current 
   tiddler.

I tried everything but could not get it - gave 30 minutes trying to look it 
up but "References" is a tricky thing to search in tiddlywiki.com as it 
means many things.

[tw5] Re: Count data dictionary values

Mario,

Smiley Face :)

Do you think we could also provide values with other inputs like 
values values{!!fieldname} values{tiddlername!!fieldname}  if it 
could parse this with spaces as the delimiter then numeric lists in a 
variable will not be deduped and can feed into our maths operators.

Perhaps values:field[fieldname] would also be valid extracting all values 
in all tiddlers with field name.

My only concern is the operator name "values" is a very generic word and we 
will have a need for more with the maths operators. 

So given the above perhaps this would be safer. 
[datatiddler(s)]values:data[]sum[]
[tiddler(s)]values:field[fieldname]sum[]

Regards
Tony

Hi Folks, 

Just had a look at the code. ... It shouldn't be that hard. 

I would like to have {{{[[data]values[]sum[]]}}} ... Which should show 2 if 
the above content is a tiddler named: data. 

I do have a new "values" operator working. I'll create a pull request 
today. 

BE AWARE!! *The code above doesn't work atm*. ... It will work in 5.1.20, 
if Jeremy merges the pull request. 

have fun!
mario
