A "characters" filter that splits the input into an array of chars

[BurningTreeC]

There's a question in the google group and I've also encountered similar problems in the past, where there would be the need for a filter that splits an input title into an array of characters, so that we can modify it further

A simple filter that splits the title, like return title.split('') would already do it I think

IMO the question you link to doesn't at all require the proposal you suggest here. (I answered the fella there with a more direct solution).

That said, I think we do need a lot more string manipulation filter ops. Could you give more use cases for your proposal here?

@twMat thanks for answering

I wouldn't say at all in this case neither ... If we don't know the ending character of a title but want it to be red nevertheless, we need to split it off from the title, wrap it within a span or div or whatever and set its css color property to red

[twMat]

Fair enuf.

But, mostly from curiosity, can you give more examples of when one would need to split up the content into an array of individual characters?

@twMat I wanted to make something like spritzinc.com some time ago using the timer plugin made by @EvanBalster - that's one example for what such a filter could be useful ... another idea would be an input field that resizes with the input text-length, as I've made at outlineproto.tiddlyspot.com (the outliner view is the use-case) ... the filter used there is very primitive and not considerable here

@BurningTreeC - interesting stuff. If you haven't already, do check out @tobibeer 's split

The method to split is closely related to https://github.com/Jermolene/TiddlyWiki5/issues/3457 which is about string search and replace. There could be a mechanism to output the result as a single string or individual characters after the operation

Eg Input 2018-10-17

Replace "-" with "" string 20181017

Replace "-" with "" character output 2 0 1 8 1 0 1 7

And it would be nice if there was a way to accept a multiline test field and output a line at a time. This would allow detailed line by line manipulation and possible programmatic search and replace text.

Post Script, Line by Line manipulation would allow text sorting of content in a text field.

with 5.1.18 I'm able to split titles and text into single characters, see:

http://127.0.0.1:8095/#MacroCollection%20-%20Examples%20-%20inverse-string:%5B%5BMacroCollection%20-%20Examples%20-%20inverse-string%5D%5D%20%24%3A%2Fmacrocollection%2FBTC%2Ftext%2Finverse-string

It's a wikitext macro that splits strings into single characters ... it inverses the string, too, and puts the single characters back together, but that's just further processing

Do you think I can close this issue?

Hi @BurningTreeC that's a localhost URL...

[AnthonyMuscio]

BTC Having opened this issue and obtaining the result you requested, It would be fair for you to close it, but as a result of this request I was hoping a search and replace character or split by line. Once you correct the link as per Jeremy, I will have a look if I can use what you have created. Tony

Sorry , here's the right URL

As of 9b2d527, this can be done with the split operator.
