The theory is to keep your root setup as solid and simple as possible to minimise things that can break, so when your normal users don't work, you can go in as root and fix the problem.
If the problem is that a linked library of zsh is broken, then you won't be able to get in as root either.
Or if your /usr partition is misbehaving, /usr/ksh (or /usr/lib/*) won't be accesssible, and neither will root.
Another argument is why do you need ksh as your root shell? You shouldn't be spending enough time in there for it to matter.
However, seeing as gentoo puts all shells into /bin, as long as you haven't got anything too complicated and you compiled ksh statically, you shouldn't have to worry. |

the only thing that bothers me a bit is that zsh's autocompletion doesn't seem to recognize new stuff. for example, when i emerge something new i have to call a new instance of zsh so autocompletion will know the new binary.
is there any option to make this a bit snappier (you know, like i'm used to with bash?)

| I hate that too. I've added: alias lzsh='source ~/.zshrc' to reload quickly after I've emerged a package. |

Is there an elegant way handle this correctly (besides putting rehash in precmd()...)? |

AFAIK, no. If its just for after a emerge, might as well write a simple wrapper script which will run rehash after a emerge. Putting it in precmd, is probably a bit overkill.
Edit: Although I did find this, from a quick google.

You probably want "setopt nohashdirs". If that doesn't do it, "nohashcmds". |
ref: http://www.zsh.org/mla/users/2001/msg00038.html
Not entirely sure that disabling hashing is a good idea though. Nor have I tested if the aforementioned works. |

Zsh thinks a "[" is the start of a math expression. Try using instead. The only problem is that it might mess with your cursor position, but it's the only way I've found to get "[" and "]" working.

Try changing the PROMPT line in your .zshrc to the following:
| Code: | PROMPT='$PR_SET_CHARSET\

$PR_SHIFT_IN$PR_LLCORNER$BLUE$PR_HBAR$PR_SHIFT_OUT%(!.#.$)$DEF ' |

Zsh does have other advantages however: a lot of it's syntax is a lot simplier than bash's. For example, to unzip some files, you can just do for x in *.zip; unzip $x. (if I recall right) |
Cool!
for i in *.mp3; mpg123 $i
This ability to handle spaces in filenames rocks. It should make scripting a lot easier. |

I have also recently converted to Zsh. It just 'feels' better than Bash, somehow.
And I have to thank slartiJ for his brilliant .zshrc. It rocks.
EDIT: I did find one thing missing, though:
The ability to use shift+tab for moving backwards through those nifty auto-completion menus.
This fixes it:
| Code: | | bindkey "\e[Z" reverse-menu-complete |
I can only get it to work with the left shift key, though... 
EDIT2: It works now, with "^[[Z" instead of "\e[Z"...

Month old problem--you've probably already fixed it & partial fix suggestions are in this thread:
| sabo wrote: | | One of the things you can do (not sure if it works in your cases, I forget One problem I have is whenever I hit delete, home, end, or anything in that area it capitalizes the letters and screws up the command. |
Here's what I use: | Code: | bindkey '^[[7~' vi-beginning-of-line # Home
bindkey '^[[8~' vi-end-of-line # End of Line
bindkey '^[[2~' beep # Insert
bindkey '^[[3~' delete-char # Del

A function that works like ctrl+r (history search) would be nice.
This works, but is cumbersome:
| Code: | % history 1- | grep 'command'
% r 'number_of_command' |

If you want all the emac bindings you can put this in your .zshrc: |

Looks like something i have to try. I will try some of your config, zsh is like fvwm, with a good one, it rocks.

Exactly!
I'm using Xfce4 at the moment, but I'm thinking about going back to FVWM. Xfce's overall level of nice-ness keeps me from doing it, though.

I tried zsh with raoul config (another Epita student ). It is all nice but some binding don't work :
for example :
ctrl+A works
ctrl+Q does not ..

What is the easiest way to get a color prompt? Up until now, I've been using print() to get the color escape sequences into the prompt.
| Code: | | PS1="$(print '%{\e[1;32m%}%n@%m%{\e[0m%}')... |

Hey all you zshers. There's some new completions in portage with the latest ~arch zsh. The list: gcc-config, quickpkg, gensync, equery, and qpkg and an updated emerge.
Equery needs to have --quiet and --nocolor before the action if you want to complete those.
Qpkg defaults to pkgnames, but make sure you supply an option before or after the package. Default qpkg behavior (qpkg zsh) is quite useless in my opinion, as it only returns app-shells/zsh *.
Emerge now has =,<,>,>=,<= support. You will need to escape the operators though. | Code: | oberyno> emerge -p \=zsh-4. ~
---- portage
zsh-4.0.9-r3 zsh-4.1.1-r5 zsh-4.2.0-r1 zsh-4.2.1_alpha1
zsh-4.1.1-r4 zsh-4.2.0 zsh-4.2.1 |
This completes all ebuilds similar to the default zsh emerge behavior. As it completes all ebuilds, you don't want to do emerge \=<tab> as there are ~15000 ebuilds and it will take a while. That being said, emerge \=g<tab> or similar is speedy. By all means if you mean to use this feature, make sure you enable cache support in your .zshrc. | Code: | zstyle ':completion::complete:*' use-cache 1
|
All the sample configs I've seen floating around here have that already. Technically, you don't need the cache, but it will be really slow. The cache is set to reset itself once a week at the moment, but no amount of time is really ideal. What would be ideal is making an alias like this in your .zshrc: | Code: | alias zsync="rm /home/user/.zcache/portage_ebuilds && rm ~/.zcache/portage_ebuilds && emerge sync"
|
where .zcache is your cache directory. Of course, thats all assuming you actually want to emerge specific ebuilds. BTW, esearch has the same cache problem and it gets around the problem with the wrapper script esync. Feel free to replace emerge sync in the above example with it.
Genlop has --date support. Here's a screenshot of it. The first tab completion is time sensitive, i.e., it won't complete december when it's august or friday when it's monday. I didn't do this for all possible combinations, because it increases the size of the completion too much. So 3rd saturday <tab> completes all months. Also, specifying a number first works. | Code: | oberyno> genlop --date 24 ~
days ago months ago weeks ago years ago |
Gensync, gcc-config and quickpkg should be perfect.
Anyway, if anyone encounters a bug, please pm me. Enjoy. |

From the looks of things everyone seems to like zsh. I will emerge it tonight and play around with it.
