我试过rake stats
,但这似乎非常不准确。也许它忽略了几个目录?

我使用免费的Perl脚本cloc。样品用法:
phrogz$ cloc .
180 text files.
180 unique files.
77 files ignored.

这是一个简单的解决方案。它计算rails项目的app文件夹中的代码行 - CSS,Ruby,CoffeeScript等。在项目的根目录下,运行以下命令:
find ./app -type f | xargs cat | wc -l

您可以尝试以下两个选项:
来自blogpost的Rakestats片段:
namespace :spec do
desc "Add files that DHH doesn't consider to be 'code' to stats"
task :statsetup do
require 'code_statistics'
class CodeStatistics
alias calculate_statistics_orig calculate_statistics
def calculate_statistics
@pairs.inject({}) do |stats, pair|
if 3 == pair.size
stats[pair.first] = calculate_directory_statistics(pair[1], pair[2]); stats
else
stats[pair.first] = calculate_directory_statistics(pair.last); stats
end
end
end
end
::STATS_DIRECTORIES << ['Views', 'app/views', /\.(rhtml|erb|rb)$/]
::STATS_DIRECTORIES << ['Test Fixtures', 'test/fixtures', /\.yml$/]
::STATS_DIRECTORIES << ['Email Fixtures', 'test/fixtures', /\.txt$/]
# note, I renamed all my rails-generated email fixtures to add .txt
::STATS_DIRECTORIES << ['Static HTML', 'public', /\.html$/]
::STATS_DIRECTORIES << ['Static CSS', 'public', /\.css$/]
# ::STATS_DIRECTORIES << ['Static JS', 'public', /\.js$/]
# prototype is ~5384 LOC all by itself - very hard to filter out
::CodeStatistics::TEST_TYPES << "Test Fixtures"
::CodeStatistics::TEST_TYPES << "Email Fixtures"
end
end
task :stats => "spec:statsetup"
PS:我没有尝试过上述任何一项,但是metric_fu听起来很有意思,请参阅输出截图。

此文件计算文件数,代码总数,注释数和每个文件的平均LOC数。它还会在名称中包含“vendor”的目录中排除文件。
用法:
count_lines('rb')
代码:
def count_lines(ext)
o = 0 # Number of files
n = 0 # Number of lines of code
m = 0 # Number of lines of comments
files = Dir.glob('./**/*.' + ext)
files.each do |f|
next if f.index('vendor')
next if FileTest.directory?(f)
o += 1
i = 0
File.new(f).each_line do |line|
if line.strip[0] == '#'
m += 1
next
end
i += 1
end
n += i
end
puts "#{o.to_s} files."
puts "#{n.to_s} lines of code."
puts "#{(n.to_f/o.to_f).round(2)} LOC/file."
puts "#{m.to_s} lines of comments."
end
