Use this tag for questions about creating your own operator within vim.
Vim allows you to create custom operators. From :help :map-operator
1.11 MAPPING AN OPERATOR *:map-operator*
An operator is used before a {motion} command. To define your own operator
you must create mapping that first sets the 'operatorfunc' option and then
invoke the |g@| operator. After the user types the {motion} command the
specified function will be called.
*g@* *E774* *E775*
g@{motion} Call the function set by the 'operatorfunc' option.
The '[ mark is positioned at the start of the text
moved over by {motion}, the '] mark on the last
character of the text.
The function is called with one String argument:
"line" {motion} was |linewise|
"char" {motion} was |characterwise|
"block" {motion} was |blockwise-visual|
Although "block" would rarely appear, since it can
only result from Visual mode where "g@" is not useful.
{not available when compiled without the |+eval|
feature}
The basic usage is to define a function, and the map your desired keystroke to
:set opfunc=MyCustomFunc<cr>g@
The g@ operator will call whatever function you have bound to opfunc, and set some marks to allow you to define how your operator should behave.
