Otherwise all aliases break that use single quotes inside.
Already fixed in the nixpkgs module in 1e211a70cbdaf230a18ea4cb67a959039d5c2ddb.
(cherry picked from commit 465d08d99f)
Add option "extraLocalVars" for additional local variable definitions
in .zshrc, at the top of the file.
Some zsh plugins/themes expect configuration in local variables before they
are loaded (example: https://github.com/bhilburn/powerlevel9k). Exporting
those clutters the environment and is unnecessary.
(cherry picked from commit 9052131aef)
Use the new module lib.zsh to generate export statements in zsh syntax, using
zsh arrays for lists.
Being a zsh script, this seems more intuitive for .zshrc
(cherry picked from commit 6b5e0efd1e)
Forcing fpath to contain unique values increases startup speed by
eliminating extra work of processing duplicated folders.
In addition, it increases startup time when zsh is enabled in both
system and home configuration due to having the same fpath value
between different compinit calls.
Fixes https://github.com/rycee/home-manager/issues/108.
Same motivation as in https://github.com/NixOS/nixpkgs/pull/28378.
zsh.initExtra parameter can be used by external modules which can
redefine user aliases. This change will give user-defined aliases
the highest priority.
1. It slows down the initial start: it takes around 2s at first launch,
and around 0.25s for the following launches;
2. It seems to be redundant since just installing zsh package gives
working completions with correct $fpath set.
