Fix HISTFILE, HISTSIZE, HISTFILESIZE that /usr/share/zsh/manjaro-zsh-config keeps overriding

[trinitronx]

The detangling of multiple problems:

• ~/.config/zsh/.zshrc Loads ~/.config/zsh/config.d/*, which includes 00-history-size.zsh
• ~/.config/zsh/.zshrc MUST Load ~/.zshrc AFTER, due to bugs in Manjaro's config:
  • Otherwise, it breaks bash select-word-style Ctrl+w yank & paste Ctrl+y
  • This is because /usr/share/zsh/manjaro-zsh-config includes the zsh-syntax-highlighting plugin before our settings are applied!
  • See: plugin breaks 'select-word-style bash' functionality zsh-users/zsh-syntax-highlighting#67
• ~/.zshrc Is loaded, and was working around the issue by setting select-word-style bash AND using ZSH_AUTOSUGGEST_IGNORE_WIDGETS workaround.
  • However, something in Manjaro config changed and ZSH_AUTOSUGGEST_IGNORE_WIDGETS workaround is now failing to work also!
  • The culprit is Autosuggest eats buffer by ctrl+w zsh-users/zsh-autosuggestions#363
  • Reference: zsh yanks only last cut word
  • Enabling BOTH select-word-style bash AND the ZSH_AUTOSUGGEST_IGNORE_WIDGETS does not work
  • Yet, with select-word-style bash disabled and $ZSH_AUTOSUGGEST_IGNORE_WIDGETS set... it works again! (╯°□°）╯︵ ┻━┻
  • Because these things must happen before + after sourcing /usr/share/zsh/manjaro-zsh-config, they are constrained to be in this file. Yet, because ~/.zshrc is sourced AFTER the ~/.config/zsh/config.d/* and thus 00-history-size.zsh, it causes a problem with HISTFILE being overridden!
  • We therefore have a Catch-22

Decided to work around part of this problem for at least HISTFILE + HISTFILESIZE by moving them into ~/.config/profile.d/. Those files get sourced at the end of ~/.zshrc, by my own design, to override anything else.

.profile source Details

$ tail -n1 ~/.zshrc:

source ${HOME}/.config/zsh/.zprofile

~/.config/zsh/.zprofile:

emulate sh -c 'source ~/.profile'

~/.profile:

#!/bin/sh

set -a
. "$HOME/.config/user-dirs.dirs"
set +a

if [ -n "$(ls "$HOME"/.config/profile.d 2>/dev/null)" ]; then
    for f in "$HOME"/.config/profile.d/*; do
        # shellcheck source=/dev/null
        . "$f"
    done
