running on macOS from upstream meld source
This is a subthread broken off from #804 to discuss issues with, and improvements to, the instructions on running this upstream project's source code directly on macOS in the interim, whilst waiting for building and packaging for macOS to be added into this upstream project. The current location for the 'run from source' instructions is https://gitlab.gnome.org/GNOME/meld/-/wikis/Running%20Meld%20on%20macOS and aside from having to run these under macOS default shell 'zsh', we already have a patch that some may require 804#note_2061358.
The next thing some folk may have to do is, before running bin/meld
paste the following snippet into zsh:
setopt interactivecomments
# ensure that the Glib Gio Settings can be found
typeset -T XDG_DATA_DIRS xdg_data_dirs :
xdg_data_dirs=("$(brew --prefix)/share" $xdg_data_dirs)
export XDG_DATA_DIRS
