Composer Downloads Plugin

This plugin allows you to download extra files and extract them within your package.

This is an updated version of civicrm/composer-downloads-plugin. It adds support for more archive files and allow custom variables.

Example

Suppose your PHP package foo/bar relies on an external archive file (examplelib-1.1.0-windows-amd64.zip on Windows, or examplelib-1.1.0-linux-x86_64.tar.gz on Linux, or examplelib-1.1.0-darwin-x86_64.tar.gz on MacOS):

{
  "name": "foo/bar",
  "require": {
    "pact-foundation/composer-downloads-plugin": "^1.0"
  },
  "extra": {
    "downloads": {
      "examplelib": {
        "url": "https://example.com/examplelib-{$version}-{$os}-{$architecture}${$musl}.{$extension}",
        "path": "extern/{$id}",
        "version": "1.1.0",
        "variables": {
            "{$musl}": "PHP_OS === 'Linux' && musl() === true ? '-musl' : ''",
            "{$os}": "strtolower(PHP_OS_FAMILY)",
            "{$architecture}": "strtolower(php_uname('m'))",
            "{$extension}": "PHP_OS_FAMILY === 'Windows' ? 'zip' : 'tar.gz'",
        },
        "ignore": ["tests", "doc", "*.md"],
        "hash": {
          "algo": "sha256",
          "value": "08fbce50f84d89fdf1fdef425c7dd1a13c5c023fa87f453ba77db4df27d273c0"
        }
      }
    }
  }
}

When a downstream user of foo/bar runs composer require foo/bar, it will download and extract the archive file to vendor/foo/bar/extern/examplelib.

Attribute:

• url: The URL to the extra file.

• path: The releative path where content will be extracted.

• type: (Optional) Determines how the download is handled. If omit, the extension in url will be used to detect.

  • Archive types (The archive file url will be downloaded and extracted to path):
    • zip: . Support extension *.zip
    • rar: Support extension *.rar
    • xz: Support extension *.tar.xz
    • tar: Support extensions *.tar.gz, *.tar.bz2, *.tar, *.tgz

    • phar: The file will be mark as executable.
    • gzip: The *.gz file will be extracted to a file that will be placed at path.

• ignore: (Optional) A list of a files that should be omited from the extracted folder.

  • This supports a subset of .gitignore notation.
  • Only useful with archive types.

• executable: (Optional) Indicate list of files should be mark as executable.

  • For archive types: the value should be a list of extracted files
