在某些文件包含 ^M 作为换行符分隔符的项目中。区分这些文件显然是不可能的,因为 git-diff 将其视为整个文件只是一行。
与以前的版本有何不同?
有没有像“差异时将 ^M 视为换行符”这样的选项?

更新:
现在我已经编写了一个 Ruby 脚本来检查最新的 10 个修订并将 CR 转换为 LF。
require 'fileutils'
if ARGV.size != 3
puts "a git-path must be provided"
puts "a filename must be provided"
puts "a result-dir must be provided"
puts "example:"
puts "ruby gitcrdiff.rb project/dir1/dir2/dir3/ SomeFile.cpp tmp_somefile"
exit(1)
end
gitpath = ARGV[0]
filename = ARGV[1]
resultdir = ARGV[2]
unless FileTest.exist?(".git")
puts "this command must be run in the same dir as where .git resides"
exit(1)
end
if FileTest.exist?(resultdir)
puts "the result dir must not exist"
exit(1)
end
FileUtils.mkdir(resultdir)
10.times do |i|
revision = "^" * i
cmd = "git show HEAD#{revision}:#{gitpath}#{filename} | tr '\\r' '\\n' > #{resultdir}/#{filename}_rev#{i}"
puts cmd
system cmd
end
