You can override a config key today with:

env HUGO_THEMESDIR=.. hugo

That works, but the support from Viper (the config library we use) is rather limited. We cannot do:

env HUGO_IMAGING_ANCHOR=top hugo

I.e. just change one setting inside a nested config struct.

Which is probably the reason why we in Hugo has a little too many top level config settings.

In my work with Hugo Modules I was about to add a couple more ... The thing is, adding a new setting adds complexity, but it's not too bad if we can somehow group it and document it in its own unit.

So, we need to improve this. We know the datatype for the target config entry, so we can:

  • Check if it's inside a map, then set that nested key.
  • If it's replaces a map, use the same unmarshaler setup we use for everything else, so you can send in JSON etc. There will probably be some Bash qouting issues, but that will be the caller's problem ...
  • If it's a slice, TODO

Add Hugo Modules
This commit implements Hugo Modules.

This is a broad subject, but some keywords include:

* A new `module` configuration section where you can import almost anything. You can configure both your own file mounts nd the file mounts of the modules you import. This is the new recommended way of configuring what you earlier put in `configDir`, `staticDir` etc. And it also allows you to mount folders in non-Hugo-projects, e.g. the `SCSS` folder in the Bootstrap GitHub project.
* A module consists of a set of mounts to the standard 7 component types in Hugo: `static`, `content`, `layouts`, `data`, `assets`, `i18n`, and `archetypes`. Yes, Theme Components can now include content, which should be very useful, especially in bigger multilingual projects.
* Modules not in your local file cache will be downloaded automatically and even "hot replaced" while the server is running.
* Hugo Modules supports and encourages semver versioned modules, and uses the minimal version selection algorithm to resolve versions.
* A new set of CLI commands are provided to manage all of this: `hugo mod init`,  `hugo mod get`,  `hugo mod graph`,  `hugo mod tidy`, and  `hugo mod vendor`.

All of the above is backed by Go Modules.
