Using an Alternate Config

A custom config file path can be specified by adding the --config flag to your hexo commands with a path to an alternate YAML or JSON config file, or a comma-separated list (no spaces) of multiple YAML or JSON files.

# use 'custom.yml' in place of '_config.yml'
$ hexo server --config custom.yml
# use 'custom.yml' & 'custom2.json', prioritizing 'custom2.json'
$ hexo server --config custom.yml,custom2.json

Using multiple files combines all the config files and saves the merged settings to _multiconfig.yml. The later values take precedence. It works with any number of JSON and YAML files with arbitrarily deep objects. Note that no spaces are allowed in the list.

For instance, in the above example if foo: bar is in custom.yml, but "foo": "dinosaur" is in custom2.json, _multiconfig.yml will contain foo: dinosaur.
