vim9: Error when using setbufline() as a method

[Yegappan Lakshmanan]

Hi,

The following vim9 script generates a E1030 error:

============================================

vim9script
var bnr = bufnr()
bnr->setbufline(1, "Hello")

============================================

The following fragment works properly:

============================================

vim9script
var bnr = bufnr()
setbufline(bnr, 1, "Hello")

============================================

Regards,

Yegappan

The base is passed as the third argument, the text. This works:

"Hello"->setbufline(bnr, 1)

The idea is that you somehow generate the text with a series of function
calls, then store it in a buffer line.

The base is passed as the third argument, the text.  This works:

        "Hello"->setbufline(bnr, 1)

Thanks. I somehow missed reading that in the help. As I was using other

buffer functions (getbufline(), setbufvar(), getbufvar(), getbufinfo(), deletebufline(),

bufloaded(), etc.) as methods using the buffer number, I tried that with the

setbufline() function.
