In a vimrc file I want to preload register C with a string I regularly need when coding. The string has a newline in it but no success in getting it to work properly.

Here is an example vimrc snippet of one of my attempts:

" Powershell block comment preload
let @c="<# Start COMMENT `n # End COMMENT #>"

in addition to '`n', I have tried `r`n, <CR>, maybe some others.

How do I represent a newline character in a 'let' statement string in vimrc, and have it work like a newline/CR when called upon to be inserted into the code (essentially inserted as a multi-line string)?

For that matter, in general, how do I represent any special character in a set/let statement string in a vimrc, and have it operate as intended when you ask for the value of that register?

You can use \n inside a double quoted string for a new line.

See :help expr-quote for more details of the special sequences available inside a double quoted string. The special sequences inside double quoted strings start with a backslash.

In your specific example, this should do:

" Powershell block comment preload
let @c = "<# Start COMMENT \n # End COMMENT #>"

You might want to adjust spacing before/after the newline, to prevent leading/trailing spaces as necessary.

    Who would have thought the vim help key word was 'expr-quote' to get this info...not to mention searching online using keywords like vimrc, newline, statement strings, special characters would yield no results. Mar 11 at 0:06
