Question

How would i assign my own indentation margin if a condition is met (ie string is included) on the previous line?
An example would be one space indentation in an if statement. thanks in advance.

input:

`int main(int argc, char **argv) {

if (argc != 1)
return(2);

if (argc != 2)
   return(3); 

for (...)

printf(“\n”);
}`

output:(using g/if/normal j>>)
shifts to the right every return line

output:(expected)

int main(int argc, char **argv) {
if (argc != 1)
 return(2);

if (argc != 2)
 return(3);   

for (...)

printf(“\n”);
}

In other words the positioning is expected to be relative to the string, and not its previous position. again, thanks for your effort @kev

:help indentexpr

You need to create a indent function.

I’ve used the following reference before.

You can also look in the indent folder of your vim install for examples.

on Max OS X

/usr/share/vim/vim73/indent
