批量验证 yaml 文件

问题描述

我需要验证一大堆 YAML 文件.

I need to validate a whole bunch of YAML files.

我尝试了 yaml 在线解析器(http://yaml-online-parser.appspot.com/) 工作完美，但是将每个 YAML 文件内容复制到框中并解析它们需要太多的手动工作.

I tried the yaml online parser (http://yaml-online-parser.appspot.com/) which works perfect, but it's too much manual work to copy each YAML file content into the box and parse them.

有没有办法批量解析/验证 YAML 文件?

Is there a way to parse/validate YAML files in bulk?

推荐答案

这在任何具有 YAML 库的脚本语言中都相当简单.例如，您可以在 Ruby 中这样做:

This is fairly straightforward in any scripting language that has a YAML library. For example, here's how you might do it in Ruby:

#!/usr/bin/env ruby

require "yaml"

def check_file(filename)
  YAML.parse_file(filename)
  puts "OK"
  0
rescue Psych::SyntaxError => ex
  puts "Error#{ex.message[/: .+/]}"
  1
end

exit_code = 0
max_filename_length = ARGV.max_by(&:size).size

ARGV.each do |filename|
  printf "%-*s  ", max_filename_length, filename
  exit_code |= check_file(filename)
end

exit exit_code

用法:

$ ruby check_yaml.rb *.yml
config-1.yml  OK
config-2.yml  OK
invalid.yml   Error: did not find expected key while parsing a block mapping at line 2 column 3
xyzzy.yml     OK

$ echo $EXIT_CODE
1
