如何拆散档案？

Question

我试图向Octopress Rakefile添加一些rake任务，我想将这些任务放到另一个子rakefile中，但是当我导入子rakefile时，它们无法访问rakefile顶部的常量。

我正在导入儿童rakefile文件，并：

Dir.glob('rakefiles/*.rake').each { |r| import r }

这是我无法在子文件中读取的配置类型：

public_dir      = "public"    # compiled site directory
source_dir      = "source"    # source file directory
blog_index_dir  = 'source'    # directory for your blog's index page (if you put your index in source/blog/index.html, set this to 'source/blog')

以下是错误：

拉克流产了！main:Object的未定义局部变量或方法`source_dir‘

Answer 1

您需要使用类变量，如

@public_dir      = "public"    # compiled site directory
@source_dir      = "source"    # source file directory
@blog_index_dir  = 'source'    # directory for your blog's index page (if you put your index in source/blog/index.html, set this to 'source/blog')

或常量

PUBLIC_DIR      = "public"    # compiled site directory
SOURCE_DIR      = "source"    # source file directory
BLOG_INDEX_DIR  = 'source'    # directory for your blog's index page (if you put your index in source/blog/index.html, set this to 'source/blog')
