Do you want to remove the last line from the file? Any better way to do this ?

No. Only the last character (a closing brace). I pushed a change to use chop() instead.

Is it possible to handle the closing brace in another way than copying (almost) the whole file ?

Alternative ? io = open("file", "r+")
seekend(io)
truncate(io, position(io)-1) # assert that position(io) >= 1, remove last character (last byte actually)
write!(io, "something")
close(io) |
Even better, you don't need to truncate, you just seek for position seekend(io)
n = position(io)
seek(io, n-1)
write(io, "something") |
…ritting everything
See the attached file as an example of the generated branching tree.
