How to get the count of italiced words in the tiddler text field of markdown format

#1

As the title says, what is the filter needed to get the count of italiced words in the tiddler text field while using markdown format.

I am using __itallics__ syntax for italics in markdown format

#2

Intuition tells me that such a thing does not exist in tiddlywiki

#3

But this might be possible by writing a markdownit plugin

#4

I was thinking regexp or search operator and count operator might be able to do it. But I was not able to put together a filter expression for doing it

#5

I am confident it can be done with TiddlyWiki functions and script. I will experiment to find a way, however do you want a count of words or a count of underlines eg This __and that__ is two __sections__ of underline but three underlined words. Can we assume the text field will not start with or end in __ ?

#6

I need the count of underlines , not the count of underlined words.
Thanks @TW_Tones for taking a look at this

yes

Lets say the tiddler underlined contains;

Sample data __with this__ and __that__,

__or this__
Then that

Now we have the function

\function underlines(tiddler) [<tiddler>get[text]split[__]count[]subtract[1]divide[2]]

then call it;

<<underlines underlined>>

We get 3.
We need two __ for each section, that why we divide by 2, but the split process will generate one more “piece” than we need so subtract by one.

  • We assume the text field will not start with or end in __, which is reasonable.

Thank you @TW_Tones
It should be like this rite ?

\function underlines(tiddler) [<tiddler>get[text]split[__]count[]divide[2]subtract[1]]

No. Tony’s formula is right. If you test this filter in Advanced search: [[__test__]split[__]count[]]. You’ll see that it returns “3” because of the split operation, you’ll always get 1 section more than there are underscores.

So first -1 than /2 should be right.

@TW_Tones @pmario
Here is a demo of the two variants of function to count underlines in tiddler text field.
I am getting the correct answer when i do the division before subtraction.

In the demo you have the function code and the text in the same tiddler.

So you also count the 1 underscore, which is part of the function and therefore is a “false positive”, which should not be counted.

So having the function code in the same tiddler is technically not the right approach. It is way to brittle. If you add a second “test” function into that tiddler you will count 2 false positives. … and so on
