Respect XDG spec?

[topazape]

Would it be possible to respect the XDG specification for config and history files generated by locating them in ${XDG_CONFIG_HOME}/pspg/pspgconf and ${XDG_CACHE_HOME}/pspg/pspg_history rather than in $HOME?

Technically there is not any problem. But pspg is a twin of psql, and what I know psql does not follow XDG. So there can be inconsistency. I am not sure how much XDG is widely used.

For example, XDG_CONFIG_HOME and XDG_CACHE_HOME are not supported on my really fresh Fedora 34

@.*** pspg-master]$ set|grep XDG XDG_CURRENT_DESKTOP=GNOME XDG_DATA_DIRS=/home/pavel/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/usr/local/share/:/usr/share/ XDG_MENU_PREFIX=gnome- XDG_RUNTIME_DIR=/run/user/1000 XDG_SESSION_CLASS=user XDG_SESSION_DESKTOP=gnome-xorg XDG_SESSION_TYPE=x11 local -a dirs=(${BASH_COMPLETION_USER_DIR:-${XDG_DATA_HOME:-$HOME/.local/share}/bash-completion}/completions); for dir in ${XDG_DATA_DIRS:-/usr/local/share:/usr/share};

So XDG support can have a lot of issues.

I am not an expert on this area - What benefits are when XDG is supported and what negatives when not?

Thanks for your reply.

• benefits
  • Bringing order to the mess of dotfiles under $HOME to standardize paths and make logical groupings.
  • All software settings can be backed up at once.
• negatives
  • May break backward compatibility

Although psql does not follow the XDG, it is possible to control the placement of configuration and history files by using environment variables ($PSQLRC and $PSQL_HISTORY). Since pspg is a great software, if it is a twin of psql, can it also support configuration file placement by environment variables?

Thank you,

I introduced variables PSPG_CONF and PSPG_HISTORY https://github.com/okbob/pspg/commit/37943a68425b13c64b972a544e5834b580cf943d - please check

I have compiled and run the new version and confirmed that the environment variables (PSPG_CONF and PSPG_HISTORY) are read correctly. Thank you very much for your quick response!
