View statistics about your code with Tokei
======
Learn details about projects' programming languages and more.
![A screen of code.][1]
Recently, GitHub added a small indicator that shows details about projects, including what programming languages a project uses. Before this, it was hard for new contributors to know this type of information about the projects they were interested in.
This addition is helpful, but what if you want to know the same information about projects in your local repository? That's where [Tokei][2] comes in handy. It's a tool that tells you code statistics about a project, which is especially useful when you want to build a project with people who are proficient in different languages.
### Exploring Tokei
According to its [README][3], "Tokei is a program that displays statistics about your code. Tokei will show the number of files, total lines within those files and code, comments, and blanks grouped by language." The introduction to its v.12.1.0 release [elaborates][4], "Tokei is a fast and accurate code analysis CLI tool and library, allowing you to easily and quickly see how many blank lines, comments, and lines of code are in your codebase." It can identify over 150 programming languages.
```
$ ./tokei ~/exa/src ~/Work/wildfly/jaxrs

### Install Tokei
To install Tokei in Fedora:
```
`$ sudo dnf install tokei`
```
To install it with Rust's Cargo package manager:
```
`$ cargo install tokei`
```
### Use Tokei
To list code statistics for the current directory:

If you run `tokei` on two files and specify their location as an argument, it prints the stats for individual files in a last-in-first-out format:

By default, `tokei` outputs only data about the languages used, but using the `--files` flag provides individual file statistics:

### Conclusion
I found it very easy to use `tokei` to learn more about my code statistics. Another good thing about `tokei` is that it can be used as a library, which makes it easy to integrate into other projects. Visit Tokei's [Crate.io page][7] and [Docs.rs][8] to learn more about its usage. If you would like to get involved, you can also contribute to Tokei through its [GitHub repository][2].
Do you find Tokei useful? Let us know in the comments section below.

使用Tokei查看有关代码的统计信息
======
了解有关项目编程语言的详细信息。
![A screen of code.][1]
近来，GitHub 添加了一个小指标来展示项目的细节，包括项目使用的编程语言。在这之前，对一个新的贡献者来说，了解他们感兴趣的项目的信息是较为困难的。
这个补充很有帮助，但是如果您想知道有关本地存储库中项目的相同信息该怎么办呢？ 这正是 [Tokei][2] 派上用场的地方。这是一个当你想和精通不同语言的人想要构建一个项目时可以告诉你项目的代码数据的特别有用的工具。
### Exploring Tokei探索 Tokei
通过它的 [README][3]，“Tokei 是一个可以展示你的代码数据的程序。Tokei 将会展示文件的数量，和这些文件中不同语言的代码、注释、空白的行数。“它的 v.12.1.0 release [elaborates][4] 是这样子介绍的，”Tokei 是一个快速准确的代码分析 CLI 工具和库，可以使你轻松快速地在你的代码库中看到有多少空白、评论和代码行“。它能够识别超过 150 中编程语言。

### 总结
我发现使用 `tokei` 来了解我的代码统计数据十分容易。另一个使用 `tokei` 的好处就是它可以用作为一个很容易集成到其他项目的库。访问 Tokei 的 [Crate.io page][7] 和 [Docs.rs][8] 网站来了解其更多用法。如果你想参与其中，你也可以通过它的 [GitHub repository][2] 来为 Tokei 作贡献。
