Notepad++ does support something like that since decades 
|
|
|
|
|
|
text = text.Trim().Replace( "\n\n", "\n" );
"Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I

I think you meant this. 
while (text.Contains("\n\n")) {
text = text.Replace("\n\n", "\n");
}
/ravi

(I think I failed to copy my own code)

That only works with completely empty lines. For a production system, you'd want a regex that matches 0 or more space/tab characters between the newlines.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

text = text.Trim().Replace( "\n\n", "\n" ).Replace("\t", "").Replace(" ", "");
Anything else?

That doesn't do what you think it does.

Props for trying, but I found out he ain't open to suggestion.

You'd want something more like this: /^\s*?(?:\r\n|\r|\n)\s*?$/gm. Notice the global modifier, it will help with the newline side of things for the second line.

Mine works ... and I can read it.

Yours works only in a very specific circumstance for something you find useful. Yours will leave any extra whitespace and make no distinction between a blank line or line with whitespace. This also means yours cannot be automated.
So, you're welcome.

a trivial AWK program would do the trick . or you can utilize regular expressions Find/Replace though i am still uncertain how to handle end of line and new line but am certain it can be done as i have been successful in past though i do not recall the details . a little learning experimentation will no doubt do the trick .

Props for mentioning regex. Most devs never take the time to learn it, but it's an extremely useful tool.

AI is often used where simple if/then's are perfectly appropriate.
But: If you integrate an AI solution then you don't just get an overblown whitespace remover, you open yourself to formatting, syntax checking, code completion, and lots of other stuff that AI is actually great at.

Every developer should take the time to learn regex. Most of the pesky grep-type problems have already been solved. Besides, AI is too busy focusing on ruling the world.

Certainly better to use AI for that rather than rely on something that actually mattered.

You seem like the sort who would use a Nutrimatic machine to simply boil dried leaves.

Those of you that are familiar with sqlxml (particularly FOR XML EXPLICIT) may know it's a series of joins with coded column names representing the attributes for each element, and keyed to a parent to nest.
Column names look like this:
Tag Parent employee!1!employeeID customer!2!customerID customer!2!region
FOR XML EXPLICIT[^] for details.
Anyway, a long time ago a friend and I collaborated for work on a generalized SQLXML layer over any oledb source, not just SQL Server. It worked great.
And later I started on generalizing *that* to work on any sort of rowset, not just databases.
Such that you can (without oledb) craft a .csv for example using FOR XML EXPLICIT rules and get a reproduction of it in XML, or turn XML into a flat CSV.
CSV is just an example. Really anything implementing IEnumerable<IDataRow> or something.
The trouble is, it's a lot of work and I'm not sure if there would be any interest in such a thing these days.
It has been a long time since I've touched bizdev.
If you're interested, can you indicate it through a response emoji or letting me know in replies? If I get enough of it that it compels me then I'll write the article and the code.
To err is human. Fortune favors the monsters.

I think more people are using JSON over XML now.
If you support both, you might draw more interest.
