Re: defining a function and E488 Trailing characters



2015-02-20 18:35 GMT+03:00 FlashBurn <rail.shafigulin@gmail.com>:
I'm trying to learn about vim scripting. I tried to define a new function on the command line with the following:

:function Meow() | echom "Meow" | endfunction

For some reason the following error show up:

E488: Trailing characters

What am I doing wrong?

Any help is appreciated.

This is the result of how :function command is implemented: instead of doing real parsing when Vim finds :function command it starts to simply consume lines up until it finds :endfunction. Characters after declaration are not considered (this is why you get this error) and lines that have `{command} | endfunction` do not end the function either (because :endfunction is not on a separate line and without real parsing there is no way to know whether it is a part of the command (e.g. let s .= "| endfunction") or a separate command).
