    1. hexo --version 看的是 hexo-cli 套件的版本，跟某個 site 要用 hexo 的哪個版本無關。
    2. hexo init HEXO_ROOT_DIR 會根據 hexo-starter 產生一個專案，以 submodule 的方式自帶 landscape theme。
    3. hexo init 在產生完專案後，會自動呼叫 yarn install 根據 package.json 安裝套件到 node_modules/ 並產生 yarn.lock；所以首頁說的 npm install 這動作就免了。
    4. 這才是 Hexo 的版本，其他 hexo-* 套件都是 plugin。
    5. 安裝完成後，跟內容相關的檔案、目錄有 _config.yml (設定)、scaffolds/ (文件樣板)、source/ (文件)、themes/ (網站樣板)。
    6. 從自動產生的 .gitignore 看來，db.json (待會執行 hexo server 會產生) 跟 node_modules/ 都不該進版本控制。
    7. hexo server 預設會在 http://localhost:4000 服務，跟文件寫的 0.0.0.0 不同 ??

Configuration ??

  • Configuration | Hexo

    • You can modify site settings in _config.yml or in an ALTERNATE config file.

    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.

    Overriding Theme Config

    • Hexo themes are INDEPENDENT PROJECTS, with separate _config.yml files.

      INSTEAD OF FORKING A THEME, and maintaining a custom branch with your settings, you can configure it from your site’s primary configuration file.

    • Example configuration:

      # _config.yml
theme_config:
  bio: "My awesome bio"

# themes/my-theme/_config.yml
bio: "Some generic bio"
logo: "a-cool-image.png"
Resulting theme configuration:

{
  bio: "My awesome bio",
  logo: "a-cool-image.png"
}

      從 theme_config 往下覆寫目前 theme 的 _config.yml，上面的例子假設目前用 my-theme，所以 _config.yml 的 theme_config: bio 會覆寫 themes/my-theme/_config.yml 裡的 bio。

      實驗發現 theme_config: footer: since: 2017 會覆寫整個 theme/_config.yml 裡的 footer:，無法單純複寫 since: 2017 這項設定。

Server

  • Server | Hexo #ril

    • With the release of Hexo 3, the server has been separated from the main module. To start using the server, you will first have to install hexo-server.

      $ npm install hexo-server --save

      hexo init 採用的樣板已經內建 hexo-server 套件。

    • Once the server has been installed, run the following command to start the server. Your website will run at http://localhost:4000 by default. When the server is running, Hexo will WATCH FOR FILE CHANGES and update automatically so it’s not necessary to manually restart the server.

      $ hexo server

      根據下面 ahuigo 的提問，_config.xml 的變動要重啟 server 才會生效：

      Hexo server does not watch for global file _config.yml changes. If you change global file, it doesn't update automatically.

    • If you want to change the port or if you’re encountering EADDRINUSE errors, use the -p option to set a different port.

      $ hexo server -p 5000

安裝設置 {: #setup }

  • 用 npm 安裝 hexo-cli 套件 (不是 hexo)，就會有 hexo 指令可以用。

    npm install -g hexo-cli

    不過這需要 Node.js 與 Git，用 Docker 相對單純。

參考資料：

  • Installation - Documentation | Hexo

    Requirements

    • Installing Hexo is quite easy. However, you do need to have a couple of other things installed first:

      • Node.js (Should be at least nodejs 6.9)
      • Git

      If your computer already has these, congratulations! Just install Hexo with npm:

      $ npm install -g hexo-cli

    • For Mac users

      You may encounter some problems when compiling. Please install Xcode from App Store first. After Xcode is installed, open Xcode and go to Preferences -> Download -> Command Line Tools -> Install to install command line tools.

      看起來用 Docker 安裝是最單純的。

Docker

  • 官方文件 完全沒提到 Docker，只能自己打包 image。
