Create a settings file

$ static-meta-scraping -i

# global
$ static-meta-scraping -i global

Example settings file

Create a file (.meta-scraping.json) with the defaults for tags to be searched.
If you specify global, the configuration file will be created in the HOME directory.

The configuration file will be prioritized in the order of current > global > library default.
Properties that do not exist in the configuration file will be applied to the library default settings.

If the configuration file exists in the current directory, the global configuration file will not be read.

Even if a configuration file exists, you can temporarily override the settings by specifying options in the command (except for search tags).

The key name of the configuration file is the same as the option name of the command.

Search

How to specify a search tag

Write the following in the configuration file.

{
  "search": [
    {
      "target": "html[lang]",
      "value": "lang"
    },
    {
      "target": "title"
    }
  ]
}

target is the tag to extract (required). If value is omitted, the default setting is applied.

If value is omitted, the default setting will be applied.

Default

Except for the following, the contents of the tag will be retrieved.

Images are converted to base64 and displayed in the result file. Supported extensions: jpg|jpeg|gif|png|webp|svg.

※Note※ Because all detected images are converted to base64, the result file may be huge if img tags are set.

Example

If the path in the file is different from the actual directory structure

e.g. directory: /dist/index.html img tag: src="/foo/assets/ogp.png

.meta-scraping.json

{
  "dir": "dist",
  "root": "/foo/"
}

Command

$ static-meta-scraping -d dist -r /foo/

If you want to extract only a specific directory in the output destination

/dist
├── /en
│   └── index.html
├── /ja
│   └── index.html
└── /foo
    └── index.html

To extract only en and ja directories

.meta-scraping.json

{
  "dir": "dist",
  "find": "en,ja"
}

Command

$ static-meta-scraping -d dist -f en,ja
