Expand config search paths #537
Description
Moving some review items from this pull request into a new issue:
#534
That pull request adds some basic user-directory search pathing for the config file. This issue expands the search paths on different platforms:
There are more places worth checking, too.
On Linux:
- $XDG_CONFIG_HOME/osvr/osvr_server_config.json
- For each colon-separated dir in $XDG_CONFIG_DIRS: $prefix/osvr/osvr_server_config.json
- /etc/xdg if $XDG_CONFIG_DIRS is not set or empty.
- /etc/osvr_server_config.json for old-school paths
- /usr/local/etc/osvr_server_config.json for old-school paths
On macOS:
- $HOME/Library/Application Support/OSVR/config/osvr_server_config.json
- /Library/Application Support/OSVR/config/osvr_server_config.json
- wherever brew installs it by default (I think /usr/local/Cellar/osvr-core/bin/osvr_server_config.json, maybe)
- /etc/osvr_server_config.json for old-school paths
- /usr/local/etc/osvr_server_config.json for old-school paths
