我一直习惯于git确定哪些文件应该进入 gem 包:

gem.files = `git ls-files`.split "\n"

不幸的是,这种方法最近被证明是不合适的。我需要一个独立的纯 Ruby 解决方案。

我的第一个想法是简单地 glob 整个目录,但仅此一项就可能包含不需要的文件。所以,在研究了这个问题之后,我想出了这个:

# example.gemspec

directory = File.dirname File.expand_path __FILE__
dotfiles = %w(.gitignore .rvmrc)
ignore_file = '.gitignore'
file_list = []

Dir.chdir directory do
  ignored = File.readlines(ignore_file).map(&:chomp).reject { |glob| glob =~ /\A(#|\s*\z)/ }
  file_list.replace Dir['**/**'] + dotfiles
  file_list.delete_if do |file|
    File.directory?(file) or ignored.any? { |glob| File.fnmatch? glob, file }
  end
end

# Later...

gem.files = file_list

这对于gemspec. 它也不完全支持gitignore's 模式格式。它目前似乎有效,但我不想以后遇到问题。

是否有一种更简单但更强大的方法来计算 gem 的文件列表?大多数宝石显然使用git ls-files,而那些既不使用类似于我的解决方案也不手动指定文件的宝石。

你好,

您可以使用纯 Ruby 列出项目的所有文件:

gem.files = Dir['**/*'].keep_if { |file| File.file?(file) }

或者您可以手动完成,Ruby on Rails gems使用此解决方案:

gem.files = Dir['lib/**/*'] + %w(.yardopts Gemfile LICENSE README.md Rakefile my_gem.gemspec)

带耙子

最简单的解决方案取决于 rake 列出目录中的所有文件,但排除文件中的所有内容.gitignore

require 'rake/file_list'
Rake::FileList['**/*'].exclude(*File.read('.gitignore').split)

红宝石宝石

官方 ruby​​gems 解决方案,手动列出和排除:

require 'rake'
spec.files = FileList['lib/*.rb',
                      'bin/*',
                      '[A-Z]*',
                      'test/*'].to_a

# or without Rake...
spec.files = Dir['lib/*.rb'] + Dir['bin/*']
spec.files += Dir['[A-Z]*'] + Dir['test/**/*']
spec.files.reject! { |fn| fn.include? "CVS" }

捆绑器

Bundler 解决方案,手动列出:

s.files = Dir.glob("{lib,exe}/**/*", File::FNM_DOTMATCH).reject {|f| File.directory?(f) }

注意:拒绝目录是没有用的,因为 gem 默认会忽略它们。

流浪汉

在纯红宝石中模仿git ls-files和照顾的流浪解决方案:.gitignore

  # The following block of code determines the files that should be included
  # in the gem. It does this by reading all the files in the directory where
  # this gemspec is, and parsing out the ignored files from the gitignore.
  # Note that the entire gitignore(5) syntax is not supported, specifically
  # the "!" syntax, but it should mostly work correctly.
  root_path      = File.dirname(__FILE__)
  all_files      = Dir.chdir(root_path) { Dir.glob("**/{*,.*}") }
  all_files.reject! { |file| [".", ".."].include?(File.basename(file)) }
  all_files.reject! { |file| file.start_with?("website/") }
  all_files.reject! { |file| file.start_with?("test/") }
  gitignore_path = File.join(root_path, ".gitignore")
  gitignore      = File.readlines(gitignore_path)
  gitignore.map!    { |line| line.chomp.strip }
  gitignore.reject! { |line| line.empty? || line =~ /^(#|!)/ }

  unignored_files = all_files.reject do |file|
    # Ignore any directories, the gemspec only cares about files
    next true if File.directory?(file)

    # Ignore any paths that match anything in the gitignore. We do
    # two tests here:
    #
    #   - First, test to see if the entire path matches the gitignore.
    #   - Second, match if the basename does, this makes it so that things
    #     like '.DS_Store' will match sub-directories too (same behavior
    #     as git).
    #
    gitignore.any? do |ignore|
      File.fnmatch(ignore, file, File::FNM_PATHNAME) ||
        File.fnmatch(ignore, File.basename(file), File::FNM_PATHNAME)
    end
  end

路径规范

使用 pathspec gemMatch Path Specifications, such as .gitignore, in Ruby!
