[dropping zsh-users from Cc: as they would only be marginally involved here]
Richard Hartmann richih.mailinglist@gmail.com: [..multiple zshrcs in grml..]
- Make ZSH load the RC files from different paths (/etc/zsh/config1 ..) Pro: Almost drop-in, minimal work necessary Cleanly seperated Different ttys might run with different RC files Con: Needs modification to fpath etc Shells can not be allowed to start prior to rc file selection
[...]
- Use $ZSHRC_PREFIX or some similar variable Pro: Drop-in solution once you change your RC files for the first time Cleanly seperated Different ttys might run with different RC files Con: Shells can not be allowed to start prior to rc file selection Needs a way for ZSH to be started with a variable set before it is invoked
I've snipped out solution no2, as I don't think that it is the best way to go.
Actually, I'm tending towards a mixture of the two remaining solutions:
1. Don't touch the current zshrc at all. It works fine and should be left intact unmodified.
2. Give all added rcs their own file + function dir (I don't think an additional completion dir is needed):
/etc/zsh/rcs/zshrc.richih /etc/zsh/rcs/richih.d/
3. Put *every* function file, that does not collide with the ones that are already in grml's configuration into /etc/zsh/functions.d; There's no reason from keeping non-colliding function to not be in the standard config.
4. add /etc/zsh/rcs/richih.d/ at the *beginning* be $fpath so that colliding functions are not taken from the default dir, but from the dir that is part of the config, that is in action.
5. If $ZSHRC_ALT (I think _ALT is a better name when choosing an alternate configuration) is set to a name (say richih), use /etc/zsh/rcs/zshrc.$ZSHRC_ALT if it is available.
Do NOT source /etc/zsh/zshrc in that case. Do NOT source ~/.zshrc in that case (set $ZDOTDIR to ~/.zshrc.$ZSHRC_ALT - that would make ~/.zshrc.$ZSHRC_ALT/.zshrc to be sourced; standard zsh mechanism.)
5. Do the handling of $ZSHRC_ALT, $ZDOTDIR and $fpath in the global zshenv (/etc/zsh/zshenv) in a
if [[ -o interactive ]] ; then fi
Block;
That should be a pretty robust yet very easy to implement way, that would leave our zshrc completely untouched and hence be still usable on other systems without a hassle. And the only thing you'd have to make sure is to set $ZSHRC_ALT before/when calling zsh.
I hope I didn't forget to wrap up one of the steps I did in my head.
