let s = 'qwerty'
Let's say I want to replace the first character by Q. I thought
the following would work
let s[0] = 'Q' but it gives
E689: Can only index a List or Dictionary
So what is the simplest way to achieve such a task ? I know
there is the substitute function but I wouldn't want to deal
with its complexities for such a simple job. The best solution I
can come up with is
function Repl_in_str(str, pos, ch)
if a:pos >= len(a:str)
echoerr "pos too large"
return a:str
endif
return strpart(a:str,0,a:pos) . a:ch . strpart(a:str , a:pos + 1)
endfunction
so I can do let s = Repl_in_str(s , 0 , 'Q')
Anyone got a better idea ?
