How can I split LaTeX source line into multiple lines?

Question

I want to split LaTeX source line

Some text I would like to have in one line~\footnote{
  something explained
}

into something like:

Some text I would like to have in one line\
~\footnote{
  something explained
}

but compiling to the same output. Is there any way to instruct LaTeX to just ignore the newline character?

A newline is the same as a space so you can split anywhere that you have a space, or you can comment out the newline with %

You show the original as

Some text I would like to have in one line~\footnote{
  something explained
}

Which already has two newlines being used as possibly spurious spaces (you are relying on \footnote to trim the spaces which will not be true of all commands. I would write it as

Some text I would like to have in one line~\footnote{%
  something explained%
}

(except I would not have a ~ before the footnote marker, but that's a style choice not a text question)

so you could have any of

Some text I would like to have in one line%
~\footnote{%
  something explained%
}

or

Some text I would like to have in one line%
~\footnote
  {something explained}

or

Some text I would like to have in one line~\footnote
  {something explained}

etc
