Include/Exclude Files or Folders

Use the following options to explicitly process or ignore certain files/folders. Support glob expressions for path matching.

include and exclude options only apply to the source/ folder, whereas ignore option applies to all folders.

Setting Description
include Include hidden files (including files/folders with a name that starts with an underscore, with an exception*)
exclude Exclude files/folders
ignore Ignore files/folders


# Include/Exclude Files/Folders
- ".nojekyll"
# Include 'source/css/_typing.css'.
- "css/_typing.css"
# Include any file in 'source/_css/'.
- "_css/*"
# Include any file and subfolder in 'source/_css/'.
- "_css/**/*"

# Exclude 'source/js/test.js'.
- "js/test.js"
# Exclude any file in 'source/js/'.
- "js/*"
# Exclude any file and subfolder in 'source/js/'.
- "js/**/*"
# Exclude any file with filename that starts with 'test' in 'source/js/'.
- "js/test*"
# Exclude any file with filename that starts with 'test' in 'source/js/' and its subfolders.
- "js/**/test*"
# Do not use this to exclude posts in the 'source/_posts/'.
# Use skip_render for that. Or prepend an underscore to the filename.
# - "_posts/" # Does not work.

# Ignore any folder named 'foo'.
- "**/foo"
# Ignore 'foo' folder in 'themes/' only.
- "**/themes/*/foo"
# Same as above, but applies to every subfolders of 'themes/'.
- "**/themes/**/foo"

Each value in the list must be enclosed with single/double quotes.

include: and exclude: do not apply to the themes/ folder. Either use ignore: or alternatively, prepend an underscore to the file/folder name to exclude.

* Notable exception is the source/_posts folder, but any file or folder with a name that starts with an underscore under that folder would still be ignored. Using include: rule in that folder is not recommended.

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.

Alternate Theme Config

Hexo themes are independent projects, with separate _config.yml files.

Instead of forking a theme, and maintaining a custom version with your settings, you can configure it from somewhere else:

from theme_config in site’s primary configuration file

Supported since Hexo 2.8.2

# _config.yml
theme: "my-theme"
bio: "My awesome bio"
bar: 'a'
# themes/my-theme/_config.yml
bio: "Some generic bio"
logo: "a-cool-image.png"
baz: 'b'

Resulting in theme configuration:

bio: "My awesome bio",
logo: "a-cool-image.png",
foo: {
bar: "a",
baz: "b"

from a dedicated _config.[theme].yml file

Supported since Hexo 5.0.0

The file should be placed in your site folder, both yml and json are supported. theme inside _config.yml must be configured for Hexo to read _config.[theme].yml

# _config.yml
theme: "my-theme"
bio: "My awesome bio"
bar: 'a'
# themes/my-theme/_config.yml
bio: "Some generic bio"
logo: "a-cool-image.png"
baz: 'b'

Resulting in theme configuration:

bio: "My awesome bio",
logo: "a-cool-image.png",
foo: {
bar: "a",
baz: "b"

We strongly recommend that you store your theme configuration in one place. But in case you have to store your theme configuration separately, you need to know the priority of those configurations: The theme_config inside site’s primary configuration file has the highest priority during merging, then the dedicated theme configuration file.
The _config.yml file under the theme directory has the lowest priority.
