Describe the Problem

  • Change -config option to -ugrid_config
  • The -ugrid_config <user_ugrid_config> is applied first and overridden by UGrid setting at the user's PointStat/GridStat configuration.
    • For example, 50km will be applied for the ugrid_max_distance_km when 50km at the user's PointStat configuration and 30km at -ugrid_config .
  • The ugrid_dataset will be ignored when -ugrid_config <user_ugrid_config>is given.

Provide a clear and concise description of the bug here.

There was a bug with -config option. There are warnings the given configuration file does not exist which is not correct.

@hsoh-u this is not a bug. Point-Stat has never supported a -config option. In the usage statement, the configuration file is given as the 3rd positional argument. So adding support for a new -config option would be an enhancement.

I do see what you're trying to do here, providing a way to specify the configuration file which describes the UGRID input data. I can think of one existing example of where a MET tool supports 2 different types of config files, and that is in the MODE tool. In the MODE Usage statement, the -config_merge option specifies the config options to be applied when doing the "engine merging" step. Following this example, you could consider adding a config option named something like -config_ugrid to be a bit more explicit about what config options are being provided here.

Changed the type to new feature and updated the title and description. -config option was added initially for UGrid configurations. I thought it can be removed, but METplus will use this option.
