About LBUFFER: is it read-only or not?

[DervishD]

    Hi all :)

    The Zsh manual says that the LBUFFER parameter is available
read-only inside completion widgets or traps while zle is active, but
I've seen inside some functions that LBUFFER is modified directly :??

    Is the manual wrong or the script is using an undocumented
feature?

There are two types of widgets.  LBUFFER can be modified from zle
widgets created using zle -N, but not from completion widgets created
with zle -C since in that case the completion code does all the
rearranging of the command line (which can be arbitrarily complicated).

    Which is the case. I didn't think about completion widgets O:))

    Thanks a lot for your answer :)
