Thanks all!
Sorry -- I normally would include an example but I sent that email from my
phone and have unreliable access to my computer (where I've been playing
with this). I am on a Mac, for what it's worth (not yet using Vim on the
iPhone :D ).
What I've tried to do is to combine a file with the contents of a buffer
and writefile() that. So here is the file test.txt:
---
Tis is
text this is
---
And this code:
---
let dir = "test"
function! Append()
let contents = readfile(g:dir . "test.txt", "b")
call add(contents, join(getline(1, '$'), "\n"))
call writefile(contents, g:dir . "does-this-work.txt", "b")
endfunction
---
when Append() is called on this buffer content:
---
This is one line of text.
This is another line.
---
gives me the file does-this-work.txt:
---
Tis is
text this is
This is one line of text.^@This is another line.
---
In other words it looks like readfile() and writefile() are indeed behaving
correctly (so that was a mistake on my part -- sorry). Where I'm having
trouble is with the getline() that gets the buffer contents. If I join()
it, I don't know how to represent the newlines (obviously '\n' doesn't
work). If I don't join() it, I get E730 ('using List as a String').
