various buggy behaviors in zsh out-of-the-box on Suse

various buggy behaviors in zsh out-of-the-box on Suse

[Mats Ahlgren]

Hello,

I recently installed zsh and have noticed some very odd behavior -- could anyone please help?

=================================
1) Bugged auto-tabbing behavior

Suppose there is a folder ~/indirection
If I type "cd indirection/[tab]", then this is what happens:

% cd indirecticd indirection/
importantSystemFiles/  wallpaper/             wine-programs@
[other contents of "indirection" folder]

As you can see, autocompletion indents the line 22 characters to the right. Here's another example after hitting *tab*:

% cd media/   cd media/
graphics/   movies/     music/      photos/     wallpaper/

This was the default behavior.

=================================
2) Bugged offset behavior with commands which overflow into new lines

Also, when a line overflows the terminal, it's almost impossible to edit a line by using the arrow keys, because when you insert characters, they get shifted.
For example, after I shrink my terminal window, here's my attempt to do "ls documents/media/wallpaper" [command completes successfully], and then hitting [up arrow] to get the thing I just typed, and then editing it to change the directory "wallpaper" to "graphics":

% ls documents/media/graphicsi
a/wallpaper
ls: cannot access docugraphicsi
a/wallpaper: No such file 
or directory

=================================
3) Annoying autocomplete behavior: 

If I have the following things in a directory:
test/
test.tgz

And I type "te[tab]" to autocomplete, it autocompletes to test/ without ever giving me the option to complete as test.tgz. Is there a way to achieve this like in bash?

Thanks,
Mats

Is this out-of-the-box from a './configure && make && make install' or
out-of-the-box from a distro-supplied package?  (I know nothing about
Suse, but I presume it has some sort of package management?)

Is behavior any different when launching zsh as "zsh -f"?  This tells
zsh to ignore RC files (my best guess off the top of my head is that
the distro-supplied RC files are broken).

This looks like either a bad terminal definition, or the shell is badly
linked to the curses library or its equivalent, or there are funny
characters in the prompt which is confusing the shell (the prompt you
show looks pretty simple but if it's something more complicated
try PS1="%# ").

This isn't the default behaviour, so something is setting an option to
turn it on.  You may find hitting <TAB> again cycles to the other file.
Look at the options in the "Completion" section of the zshoptions manual
for hints.  MENU_COMPLETE or REC_EXACT are possibilities, depending
exactly what it's doing.

Hello, thanks for replying; you've helped solve almost all my problems.

Apparently I *did* make a few modifications and forgot about them... I feel ridiculous about my previous default behavior comment, sorry.
Still have one questions if you'd be so kind:

# excerpt from .zshrc

# COLORIZE PROMPT
autoload colors; colors

# Prompt
PS1="
$bg[black]$fg[blue]%B%#%b $fg[white]%B"


 Apparently using the variables $bg[...] and $fg[...], etc., seems to be causing this bug. Might you or anyone have any insight as to why?

Apparently I was looking for "auto_menu" -- problem solved.

Many thanks,
Mats

You need to tell the shell that the characters in those variables
don't move the cursor:  it has no knowledge of terminal escapes so
assumes every character moves the cursor one character to the right.
Try:

PS1="
%{$bg[black]$fg[blue]%}%B%#%b %{$fg[white]%}%B"
