Cobra, the CLI commander in use in Hugo, has some long awaited improvements in the error handling department.
This enables a more centralized error handling approach.
This commit introduces that by changing all the command funcs to `RunE`:
* The core part of the error logging, usage logging and `os.Exit(-1)` is now performed in one place and that one place only.
* The usage text is now only shown on invalid arguments etc. (user errors)
Fixes#1502
If flag is passed the site will be created inside non-empty folder
only if there are no existent folders or config with the same name
hugo creates.
Resolves: #1163
- Add copyright years and author to the top of the file
- Write the current year from time.Now() to LICENSE.md
- Correct comment regarding `os.MkdirAll(p, 0777)`
- In createConfig(), split the `map[string]string` definition into
multiple lines to facilitate future expansion. Also add a trailing
slash to sample "baseurl" definition.
- Update theme.toml template to match that listed at
https://github.com/spf13/hugoThemes/blob/master/README.md#themetoml
See #883 for an equivalent `struct` implementation
