The Source Code Line Counter And Analyzer
|
||||
======
|
||||
|
||||
|
||||
|
||||
**Ohcount** is simple command line utility that analyzes the source code and prints the total number lines of a source code file. It is not just source code line counter, but also detects the popular open source licenses, such as GPL, within a large directory of source code. Additionally, Ohcount can also detect code that targets a particular programming API such as KDE or Win32. As of writing this guide, Ohcount currently supports over 70 popular programming languages. It is written in **C** programming language and is originally developed by **Ohloh** for generating the reports at [www.openhub.net][1].
|
||||
|
||||
In this brief tutorial, we are going to how to install and use Ohcount to analyze source code files in Debian, Ubuntu and its variants like Linux Mint.
|
||||
|
||||
### Ohcount – The source code line counter
|
||||
|
||||
**Installation**
|
||||
|
||||
Ohcount is available in the default repositories in Debian and Ubuntu and its derivatives, so you can install it using APT package manager as shown below.
|
||||
```
|
||||
$ sudo apt-get install ohcount
|
||||
|
||||
```
|
||||
|
||||
**Usage**
|
||||
|
||||
Ohcount usage is extremely simple.
|
||||
|
||||
All you have to do is go to the directory where you have the source code that you want to analyze and ohcount program.
|
||||
|
||||
Say for example, I am going to analyze the source of code of [**coursera-dl**][2] program.
|
||||
```
|
||||
$ cd coursera-dl-master/
|
||||
|
||||
$ ohcount
|
||||
|
||||
```
|
||||
|
||||
Here is the line count summary of Coursera-dl program:
|
||||
|
||||
![][4]
|
||||
|
||||
As you can see, the source code of Coursera-dl program contains 141 files in total. The first column specifies the name of programming languages that the source code consists of. The second column displays the number of files in each programming languages. The third column displays the total number of lines in each programming language. The fourth and fifth lines displays how many lines of comments and its percentage in the code. The sixth column displays the number of blank lines. And the final and seventh column displays total line of codes in each language and the gross total of coursera-dl program.
|
||||
|
||||
Alternatively, mention the complete path directly like below.
|
||||
```
|
||||
$ ohcount coursera-dl-master/
|
||||
|
||||
```
|
||||
|
||||
The path can be any number of individual files or directories. Directories will be probed recursively. If no path is given, the current directory will be used.
|
||||
|
||||
If you don’t want to mention the whole directory path each time, just CD into it and use ohcount utility to analyze the codes in that directory.
|
||||
|
||||
To count lines of code per file, use **-i** flag.
|
||||
```
|
||||
$ ohcount -i
|
||||
|
||||
```
|
||||
|
||||
**Sample output:**
|
||||
|
||||
![][5]
|
||||
|
||||
Ohcount utility can also show the annotated source code when you use **-a** flag.
|
||||
```
|
||||
$ ohcount -a
|
||||
|
||||
```
|
||||
|
||||
![][6]
|
||||
|
||||
As you can see, the contents of all source code files found in this directory is displayed. Each line is prefixed with a tab-delimited language name and semantic categorization (code, comment, or blank).
|
||||
|
||||
Some times, you just want to know the license used in the source code. To do so, use **-l** flag.
|
||||
```
|
||||
$ ohcount -l
|
||||
lgpl3, coursera_dl.py
|
||||
gpl coursera_dl.py
|
||||
|
||||
```
|
||||
|
||||
Another available option is **-re** , which is used to print raw entity information to the screen (mainly for debugging).
|
||||
```
|
||||
$ ohcount -re
|
||||
|
||||
```
|
||||
|
||||
To find all source code files within the given paths recursively, use **-d** flag.
|
||||
```
|
||||
$ ohcount -d
|
||||
|
||||
```
|
||||
|
||||
The above command will display all source code files in the current working directory and the each file name will be prefixed with a tab-delimited language name.
|
||||
|
||||
To know more details and supported options, run:
|
||||
```
|
||||
$ ohcount --help
|
||||
|
||||
```
|
||||
|
||||
Ohcount is quite useful for developers who wants to analysis the code written by themselves or other developers, and check how many lines that code contains, which languages have been used to write those codes, and the license details of the code etc.
|
||||
|
||||
And, that’s all for now. Hope this was useful. More good stuffs to come. Stay tuned!
|
||||
|
||||
Cheers!

源代码行计数器和分析器
|
||||
======
|
||||
|
||||
|
||||
|
||||
**Ohcount** 是一个简单的命令行工具，可用于分析源代码并打印代码的总行数。它不仅仅是代码行计数器，还可以在含有大量代码的目录中检测流行的开源许可证，例如 GPL。此外，Ohcount 还可以检测针对特定编程 API（例如 KDE 或 Win32）的代码。在编写本指南时，Ohcount 目前支持 70 多种流行的编程语言。它用 **C** 语言编写，最初由 **Ohloh** 开发，用于在 [www.openhub.net][1] 中生成报告。
|
||||
|
||||
在这篇简短的教程中，我们将介绍如何安装和使用 Ohcount 来分析 Debian、Ubuntu 及其变体（如 Linux Mint）中的源代码文件。
|
||||
|
||||
### Ohcount – 代码行计数器
|
||||
|
||||
**安装**
|
||||
|
||||
Ohcount 存在于 Debian 和 Ubuntu 及其派生版的默认仓库中，因此你可以使用 APT 软件包管理器来安装它，如下所示。
|
||||
```
|
||||
$ sudo apt-get install ohcount
|
||||
|
||||
```
|
||||
|
||||
**用法**
|
||||
|
||||
Ohcount 的使用非常简单。
|
||||
|
||||
你所要做的就是进入你想要分析代码的目录并执行程序。
|
||||
|
||||
举例来说，我将分析 [**coursera-dl**][2] 程序的源代码。
|
||||
```
|
||||
$ cd coursera-dl-master/
|
||||
|
||||
$ ohcount
|
||||
|
||||
```
|
||||
|
||||
以下是 Coursera-dl 的行数摘要：
|
||||
|
||||
![][4]
|
||||
|
||||
如你所见，Coursera-dl 的源代码总共包含 141 个文件。第一列说明源码含有的编程语言的名称。第二列显示每种编程语言的文件数量。第三列显示每种编程语言的总行数。第四行和第五行显示代码中由多少行注释及其百分比。第六列显示空行的数量。最后一列和第七列显示每种语言的全部代码行数以及 coursera-dl 的总行数。
|
||||
|
||||
或者，直接使用下面的完整路径。
|
||||
```
|
||||
$ ohcount coursera-dl-master/
|
||||
|
||||
```
|
||||
|
||||
路径可以是任何数量的单个文件或目录。目录将被递归探测。如果没有给出路径，则使用当前目录。
|
||||
|
||||
如果你不想每次都输入完整目录路径，只需 cd 进入它，然后使用 ohcount 来分析该目录中的代码。
|
||||
|
||||
要计算每个文件的代码行数，请使用 **-i** 标志。
|
||||
```
|
||||
$ ohcount -i
|
||||
|
||||
```
|
||||
|
||||
**示例输出：**
|
||||
|
||||
![][5]
|
||||
|
||||
当您使用 **-a** 标志时，ohcount 还可以显示带标注的源码。
|
||||
```
|
||||
$ ohcount -a
|
||||
|
||||
```
|
||||
|
||||
![][6]
|
||||
|
||||
如你所见，显示了目录中所有源代码的内容。每行都以制表符分隔的语言名称和语义分类（代码、注释或空白）为前缀。
|
||||
|
||||
有时候，你只是想知道源码中使用的许可证。为此，请使用 **-l** 标志。
|
||||
```
|
||||
$ ohcount -l
|
||||
lgpl3, coursera_dl.py
|
||||
gpl coursera_dl.py
|
||||
|
||||
```
|
||||
|
||||
另一个可用选项是 **-re**，用于将原始实体信息打印到屏幕（主要用于调试）。
|
||||
```
|
||||
$ ohcount -re
|
||||
|
||||
```
|
||||
|
||||
要递归地查找给定路径内的所有源码文件，请使用 **-d** 标志。
|
||||
```
|
||||
$ ohcount -d
|
||||
|
||||
```
|
||||
|
||||
上述命令将显示当前工作目录中的所有源码文件，每个文件名将以制表符分隔的语言名称为前缀。
|
||||
|
||||
要了解更多详细信息和支持的选项，请运行：
|
||||
```
|
||||
$ ohcount --help
|
||||
|
||||
```
|
||||
|
||||
对于想要分析自己或其他开发人员开发的代码，并检查代码的行数，用于编写这些代码的语言以及代码的许可证详细信息等，ohcount 非常有用。
|
||||
|
||||
就是这些了。希望对你有用。会有更好的东西。敬请关注！
|
||||
|
||||
干杯!
