出于好奇，有没有办法获得你编写的代码行数（在特定项目中）？
我尝试使用p4 describe #CLN | wc -l，但除了这么多边缘情况（包含注释，添加新行等）之外，它还会跳过新添加的文件。边缘情况可以忽略，如果我们尝试显示物理代码行，但新添加的文件仍会导致问题。
答案 0 :(得分：5)
我继续写了一个Python脚本，打印出用户添加/更改的代码行数以及每次更改的平均行数。
使用Python 2.7.2在Windows上测试。您可以从命令行运行 - 它假定您的路径中有p4。
用法：codestats.py -u [用户名]
它也适用于git：codestats.py -u [authorname] -g。
它进行了一些黑名单以删除批量添加（例如，您刚添加了一个库），并且还对某些类型的文件（例如.HTML文件等）强加了黑名单。否则，它的效果非常好。
希望这有帮助！

是的，有很多方法可以计算代码行数。
tl; dr 安装Eclipse Metrics Plugin。 Here是如何做到的指令。如果你想在没有Eclipse的情况下这样做，下面有一个简短的脚本。
外壳脚本
我将向您介绍非常一般的方法。它适用于Linux，但它可以移植到其他系统。将这2行保存到lines.sh文件：
#!/bin/sh
find -name "*.java" | awk '{ system("wc "$0) }' | awk '{ print $1 "\t" $4; lines += $1; files++ } END { print "Total: " lines " lines in " files " files."}'
这是一个使用find，wc和精彩awk的shell脚本。添加执行权限：
chmod +x lines.sh
现在我们可以执行我们的shell脚本了。
假设您在lines.sh中保存了/home/you/workspace/projectX
脚本计算.java个文件中的行，这些文件位于/home/you/workspace/projectX的子目录中。
所以让我们用./lines.sh运行它。您可以为任何其他类型的文件更改*.java。
示例输出：

其他答案似乎错过了源控制历史方面的事情。
来自http://forums.perforce.com/index.php?/topic/359-how-many-lines-of-code-have-i-written/
分多步计算答案：
1）添加了文件：
p4 filelog ... | grep ' add on .* by <username>'
p4 print -q foo#1 | wc -l
2）更改了文件：
p4 describe <changelist> | grep "^>" | wc -l
将所有计数合并在一起（编写脚本......），您将获得总计。
你可能还想用grep删除空白行或没有字母数字字符的行？
另外，如果你经常这样做，那么在P4Python中对事物进行编码并以增量方式执行它会更有效 - 保留历史记录并仅查看新的提交。
答案 3 :(得分：0)
找一个用来计算线条的应用程序，计算行数有很多细微之处 - 注释，空白行，每行多个运算符等。
Visual Studio具有＆＃34;计算代码指标＆＃34;功能，因为您没有提及单一语言，我可以更具体地说明使用哪种工具，只是说＆＃34;找到＆＃34;和＆＃34; grep＆＃34;可能不是一条路。
还要考虑代码行不能衡量实际进度的事实。路线图上已完成的功能可衡量进度，代码行越少越好。如果一个自豪的开发人员声称他的60,000行代码非常出色，那么它就不会是第一个，只是为了找到那种在1000行中做同样事情的方法。

有一种更简单的方法可以做到这一切，顺便提一下比使用grep更快：
首先获取特定用户的所有更改列表，这是一个命令行命令，您可以使用os.system（）在python脚本中使用它：
p4 changes -u <username> > 'some_text_file.txt'
现在你需要提取所有的更改列表编号，我们将使用正则表达式，这里使用python完成：
f = open('some_text_file.txt','r')
lists = f.readlines()
pattern = re.compile(r'\b[0-9][0-9][0-9][0-9][0-9][0-9][0-9]\b')
labels = []
for i in lists:
labels.append(pattern.findall(i))
changelists = []
for h in labels:
if(type(h) is list):
changelists.append(str(h[0]))
else:
changelists.append(str(h))
现在您已在＆＃39;标签＆＃39;中包含所有更改列表编号。 我们将遍历列表，并且对于每个更改列表，查找添加的行数和删除的行数，获得最终差异将给出我们添加的总行数。以下代码留下了这一点：
for i in changelists:
os.system('p4 describe -ds '+i+' | findstr "^add" >> added.txt')
os.system('p4 describe -ds '+i+' | findstr "^del" >> deleted.txt')
added = []
deleted = []
file = open('added.txt')
for i in file:
added.append(i)
count = []
count_added = 0
count_add = 0
count_del = 0
for j in added:
count = [int(s) for s in j.split() if s.isdigit()]
count_add += count[1]
count = []
file = open('deleted.txt')
for i in file:
deleted.append(i)
for j in labels:
count = [int(s) for s in j.split() if s.isdigit()]
count_del += count[1]
count = []
count_added = count_add - count_del
print count_added
count_added将包含用户添加的行数。
