How to render [ ] in Tiddler title?

[Cd.K]

Here's what I've been trying to do:

I want:

tiddlers created [01.09.2019 to 15.09.2019[

Is this possible?

I am not exactly sure of your request however I will assume you want to list tiddlers with a created date between 

01.09.2019 to 15.09.2019

When you transclude the created and modified dates like this

{{!!created}}

Tiddlywiki intervieins to display it in a data format.

However it is contained within the hidden created field, according to this format https://tiddlywiki.com/#Date%20Fields

You can see this using 

<$text text={{!!created}}/>

eg

20190919063745877

So since the values in a date go from most significant years, to least significant milliseconds it is a number that can be used for comparisons.

Yes there are numbers that are not valid like the 99th of a month but they remain in sequence.

So in your example you need only test if the prefix YYYYMMDD is between 20190901 and 20190915

The reveal widget contains a test for greater than and less than.

However in your example you also have a range that could be expressed with the days[-14] operator on the 20190915 second date or days[+14] on the first.

I will leave the balance of this issue to you or another contributor.

My request is because of this "bad-chars" warning:

I only want to be able to have [ ] chars in a tiddler title.

Well with Respect, you do want to do something it is telling you not to. Avoid using [ ] in tiddler titles.

• Why are you doing this? 
• Is there something unstated here you want to do?
• Surly it not just a preference for [ ]?

Try ( ) instead. Or place in the tiddler

<h1>tiddlers created [01.09.2019 to 15.09.2019]</h1>

or use the title

tiddlers created: 01.09.2019 - 15.09.2019

There are possibilities to make it look as you desire, you could hack the way and what is displayed in 

$:/core/ui/ViewTemplate/title

However, Let's return to the real problem you are trying to solve before you adopt exceptional solutions.

It means:

tiddlers created: inclusive 01.09.2019 - 15.09.2019 exclusive

It is simply a mathematical notation of range boundaries.

Thanks for the hint

$:/core/ui/ViewTemplate/title

Unless you has a really good reason don't hack 

$:/core/ui/ViewTemplate/title

Here's a cheat that can be copy pasted. I have no idea how these characters show in different browsers but in mine they're variants of square brackets

⦏ ⦎ 

⁅ ⁆

⟦ ⟧

⦋ ⦌

This is quite easy but the way you tackle the problem seems not inline with TW!

See examples here

http://tw-regexp.tiddlyspot.com/#RegExp%20Experimentation%20with%20Created%20Field

Note that, TW used created and modified field where you see when your tiddler created or modified!

Good luck

[Mohammad]

This is a bad practice!

Avoid using [] in tiddler title!

I think it is better to explain what you want to in Tiddlywiki instead of your approach to solve it!

Not tested but this should work.

Simply create a tiddler and paste the below code inside it

<$edit-text tag="input" size="40" tiddler="mycreated" default="" placeholder=" regexp pattern"/>

<$set name=pattern value={{mycreated}} emptyValue="::No pattern">

Number of tiddlers found: <$count filter="[!is[system]!is[shadow]regexp:created<pattern>]"/><br>

<dl>

<$list filter="[!is[system]!is[shadow]regexp:created<pattern>]">

<dt><$link/></dt>

<dd><$view field=created format=date template="YYYY.0MM.0DD"/></dd>

</$list>

</dl>

</$set>

If you use 

^201909[01]

Then all tiddlers created from 2019.09.01 to 2019.09.19 are created will be listed! (system and shadow tiddlers are excluded)

 

For you case I think

(^2019090|^2019091[012345])

Should work!

Not tested

Mark and Josiah may have better solution.

A couple of regex solutions have been proposed that work to match the "created" field for the range.

The only issue is its pure pattern, not maths informed.

I was wondering if any of the other operators could do this too?

For instance the "days" operator. https://tiddlywiki.com/#days%20Operator

Can you set a date it would start from in a filter?

For you case I think

(^2019090|^2019091[012345])

Should work!

Neat! It could be slightly more compact 

(^2019090|^2019091[0-5])

A version that does the same but without needing a variable to escape the [...] brackets. 

Can be used directly in Advanced Search Filter ...

[regexp:created[(^2019090|^2019091(0|1|2|3|4|5))]]

This offer ⦏ ⦎ is good for me.👍

Gives the impression of dirt on the screen if you don't look closely.

Thanks

I just want the possibility to mask/escape special chars in tiddler titles. It renders "[" oder"]" and you don't have problems with this chars.

Works!

My new tiddler:

"Mohammad regexpr list filter tool"

Thanks

I am Glad you find it useful!

By the way at http://tw-regexp.tiddlyspot.com

We have collected few regexp patterns to search in title, fields (excluding text) and partially on text.

Using these as I sent above needs its own input box and should not be used with advanced search.

Cheers
