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:
|
|||
|
|
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ tokei

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:
|
|||
|
|
|
|||
|
|
|
|||
|
|
```

$ tokei ~/exa/src --files

### 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].
