[HELP] Get Line Number using the content of a Line as input

[FelipeRearden]

Hello friends !!!

I have a question about content from a Specific Line.

As we know, we can get the content from a specific line like this:

const editor = app.workspace.activeLeaf.view.editor;
const lnum = editor.getCursor().line;
const fnum = editor.getLine(lnum)
new Notice(fnum, 10000);

MY QUESTION is about the reverse. Does anybody know how to get the LINE NUMBER using the content of a line as the input?

Example:
● the content of line 5 is "Lorem Ipsum"
● I need a snippet to use "Lorem Ipsum" as input and get 5 as result.

My workflow: I am using .match(); to filter tp.file.content in a suggester. After selecting the "content" from the suggester, I need the line number to use app.workspace.activeLeaf.view.editor.setCursor() to go to the desired line.

Does anybody could help me ? 🙏🙏🙏
Thanks for reading this

Messing around in one of my random list files and using tp directly i found this works to output the current file line number of a given text:
<% tp.file.content.split("\n").indexOf("<search_text_here>") %>

I would imagine this would need to be expanded upon for larger file sizes, but in a pinch and shorter file lengths this is probably fine.

note: .indexOf() returns 0 on the first element, so you'd need to add one if that matters
