确定gem的规范文件列表

Question

我总是使用git来确定哪些文件应该放入gem包中：

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

不幸的是，this approach has recently proved to be inappropriate。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整理整个目录，但仅此一项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

gemspec似乎有点复杂。它也不完全支持gitignore's pattern format。它目前似乎有效，但我不会在以后遇到问题。

是否有更简单但更健壮的方法来计算gem的文件列表？大多数宝石显然都使用git ls-files，并且不使用与我类似的解决方案或手动指定文件。

Answer 1

您好，

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) }

或者您可以手动执行此操作，此解决方案由Ruby on Rails gems使用：

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

Answer 2

有了耙子

根据rake列出目录中的所有文件，但排除.gitignore文件中的所有内容的最简单解决方案：

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

RubyGems

官方的rubygems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

捆绑器解决方案，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默认情况下会忽略它们。

流浪者

在纯红宝石中模仿git ls-files并照顾.gitignore的无用解决方案：

  # 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

Pathspec

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