import { fn } from "https://deno.land/x/ddc_vim@v4.0.2/deps.ts";
const { getreg } = fn;
The result is a String, which is the contents of register {regname}. Example:
:let cliptext = getreg('*')
When register {regname} was not set the result is an empty string. The {regname} argument must be a string.
getreg('=') returns the last evaluated value of the expression
register. (For use in maps.)
getreg('=', 1) returns the expression itself, so that it can
be restored with setreg(). For other registers the extra
argument is ignored, thus you can always give it.
If {list} is present and TRUE, the result type is changed
to List. Each list item is one text line. Use it if you care
about zero bytes possibly present inside register: without
third argument both NLs and zero bytes are represented as NLs
(see NL-used-for-Nul).
When the register was not set an empty list is returned.
If {regname} is "", the unnamed register '"' is used.
If {regname} is not specified, v:register is used.
In Vim9-script {regname} must be one character.
Can also be used as a method:
GetRegname()->getreg()
