如何改进我的 Rakefile（部署）

发布于 2025-01-06 12:22:50 字数 1462 浏览 2 评论 0原文

我正在编写我的第一个 Rakefile。我在文档中看到的第一件事是 “Rakefile 没有特殊格式”< /a> 和“Rakefile 中没有特殊语法”。

好吧，所以我必须自己想出一些办法，但我可以看到我的生物至少有两个问题：

1)我需要创建许多文件夹，其中五个。 6 个目录 任务的顺序看起来有点奇怪。 deploy 任务中的 5 个依赖项列表看起来更奇怪。我能以某种方式将其缩小到一行吗？

2) 我需要重复我的目录名称文字两次 - 当我定义它们的部署路径时以及当我复制内容时。我可以在不引入另外 5 个变量的情况下避免这种情况吗？

在 Java Ant 中，我将创建一个包含所有名称文字的属性文件 - 我可以使用 Rake 做到这一点吗？

这就是我所得到的：

WEBAPPSDIR = '/var/webapps/'
WEBAPPNAME = 'foo.local'
WEBAPPDIR = File.join(WEBAPPSDIR, WEBAPPNAME)
VIEWSDIR = File.join(WEBAPPDIR, 'views')
PUBLICDIR = File.join(WEBAPPDIR, 'public')
CSSDIR = File.join(PUBLICDIR, 'css')
IMAGESDIR = File.join(PUBLICDIR, 'images')
TMPDIR = File.join(WEBAPPDIR, 'tmp')
HTMLDIR = File.join(PUBLICDIR, 'html')

directory VIEWSDIR
directory CSSDIR
directory HTMLDIR
directory IMAGESDIR
directory TMPDIR

desc 'Deploy to webapps dir'
task :deploy => [VIEWSDIR, CSSDIR, IMAGESDIR, TMPDIR, HTMLDIR] do
  cp 'config.ru', WEBAPPDIR
  Dir.glob('*.rb') {|f| cp f, WEBAPPDIR}
  Dir.glob('views/*.{mab,str}') {|f| cp f, VIEWSDIR}
  Dir.glob('css/*.css') {|f| cp f, CSSDIR}
  Dir.glob('images/*.{png,jpg,gif}') {|f| cp f, IMAGESDIR}
  Dir.glob('html/*.html') {|f| cp f, VIEWSDIR}
end

desc 'Cleans webapp dir'
task :clean do
  rm_r WEBAPPDIR, {force: true}
end

也欢迎其他想法/链接/示例。

原文

I'm writing my first Rakefile. The first things that I see in the doc is "there is no special format for a Rakefile" and "there is no special syntax in a Rakefile".

Ok, so I had to come up with something on my own, but I can see at least two problems with my creature:

1) I need to create a number of folders, five of them. The sequence of 6 directory tasks looks a bit weird. The list of 5 dependencies in deploy task looks even more weird. Can I shrink it down to one line somehow?

2) I need to repeat my directory name literals two times - when I define their deployment paths and when I copy the contents. Can I avoid that without introducing 5 more variables?

In Java Ant I would create a properties file with all name literals - can I do that with Rake?

This is what I've got:

WEBAPPSDIR = '/var/webapps/'
WEBAPPNAME = 'foo.local'
WEBAPPDIR = File.join(WEBAPPSDIR, WEBAPPNAME)
VIEWSDIR = File.join(WEBAPPDIR, 'views')
PUBLICDIR = File.join(WEBAPPDIR, 'public')
CSSDIR = File.join(PUBLICDIR, 'css')
IMAGESDIR = File.join(PUBLICDIR, 'images')
TMPDIR = File.join(WEBAPPDIR, 'tmp')
HTMLDIR = File.join(PUBLICDIR, 'html')

directory VIEWSDIR
directory CSSDIR
directory HTMLDIR
directory IMAGESDIR
directory TMPDIR

desc 'Deploy to webapps dir'
task :deploy => [VIEWSDIR, CSSDIR, IMAGESDIR, TMPDIR, HTMLDIR] do
  cp 'config.ru', WEBAPPDIR
  Dir.glob('*.rb') {|f| cp f, WEBAPPDIR}
  Dir.glob('views/*.{mab,str}') {|f| cp f, VIEWSDIR}
  Dir.glob('css/*.css') {|f| cp f, CSSDIR}
  Dir.glob('images/*.{png,jpg,gif}') {|f| cp f, IMAGESDIR}
  Dir.glob('html/*.html') {|f| cp f, VIEWSDIR}
end

desc 'Cleans webapp dir'
task :clean do
  rm_r WEBAPPDIR, {force: true}
end
