Netrw failure with latest Vim
Hi all, I've updated Vim to 7.3.744 (features=big) and now netrw fails the second time I try to open a file using :Explore 1. Start vim 2. :E and open a file 3. :E fails At step 3 I get a blank screen with no listing. This seems to be caused by this line in my .vimrc: let g:netrw_liststyle=3 If I comment this line, everything works as expected. This is on a Debian Squeeze with netrw v146. -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to.

On Kubuntu 12.10, vim 7.3.742, Huge version with GTK2-GNOME, starting vim with vim -u NONE -N -c 'let g:netrw_liststyle=3' \ -c 'so $VIMRUNTIME/plugin/netrwPlugin.vim' on step 3 I get an empty screen, like that of an empty buffer, tildes down the left. Press i, and the next type of netrw listing is displayed correctly. Cycling through them with i, the tree listing screen is empty and the others ok. Attempting to install the latest netrw...

I see this problem, too (on a Scientific Linux box). Note the following: 1. start vim 2. :Ex . 3. Pick some file :ls! You'll see something like 4u# - "NetrwTreeListing 1" line 17 (the line number is showing the line number of the file you selected in the NetrwTreeListing buffer) So, the NetrwTreeListing buffer is unlisted, is an alternate buffer (for :e #), and the current line number is 17. 4. :b 4 The NetrwTreeListing buffer is now empty. This is what is happening, essentially, to netrw when it tries to bring up the NetrwTreeListing buffer. Unfortunately, I haven't been able to duplicate this loss of buffer with a simpler example as yet. Regards, Chip Campbell -- You received this message from the "vim_dev" maillist. Do not top-post!

Confirming problem tied to setting liststyle in vimrc; problem disappears when set line commented. -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to. For more information, visit http://www.vim.org/maillist.php

I tried it with the commands you gave above; I'm afraid that its still "it worked for me". Try :set verbose=20 before you do the :runtime command and see if netrwPlugin.vim actually gets loaded (without running into the finish).

Re: Netrw failure with latest Vim
I've just spent a few hours trying to track this down. It was very frustrating
as vim's behaviour became unpredictable, though I think I know the cause.
Using :Decho went bananas until I found the comment that explained that
DechoTabOn was necessary, but even that was subject to weirdness caused by the
autocommands running the code being debugged, which interacted with the problem
I was trying to find.
Anyway, to cut a long story short, in V147b the variable g:netrw_xstrlen is
used when it doesn't exist in the function s:Strlen in autoload/netrw.vim, when
it is called in s:LocalListing. Maybe there's :silent on the way to that
point, but s:Strlen's execution is abandoned; trace statements towards the end
(such at the call Dret) are not executed, and the listing code uses a directory
length of 0. If g:netrw_xstrlen or g:Align_xstrlen or g:drawit_xstrlen is
defined, the problem does not occur. Perhaps Dr Chip you have one of those set.
I'm not sure, but I think the code that checks the existence of g:netrw_xstrlen
should look like
if !exists("g:netrw_xstrlen")
if exists("g:Align_xstrlen")
let g:netrw_xstrlen= g:Align_xstrlen
else
if !exists("g:drawit_xstrlen")
if &enc == "latin1" || !has("multi_byte")
let g:drawit_xstrlen= 0
else
let g:drawit_xstrlen= 1
endif
endif
let g:netrw_xstrlen= g:drawit_xstrlen
endif
endif

Good catch -- I do have "one of those set", but the vim -u NONE -N
shouldn't have loaded my .vimrc, and so I'm mystified as to why I didn't
run into the problem you were having. I've made a related fix for this
issue. Thanks!
I'm going to try to work on or find a way to simply duplicate the other
problem on this thread awhile before I update netrw on my website.

Chip Campbell

I can reproduce it with vim -u NONE -N -c 'so $VIMRUNTIME/plugin/netrwPlugin.vim' :e . iii Maybe your .vim/.netrwhist needs to be set aside.
