[rust weekly library] Tokei - a utility for statistics of code lines and other information
2022-06-30 00:06:00 【51CTO】
Tokei It is a tool to count the number of code lines and other statistical information by language . In fact, this information is very useful , First of all, program apes can use it to estimate the strength of others or observe the growth rate of their own strength （ What a horse , Number theory hero ？）. secondly , Managers can use it to estimate the progress and budget of the project （ It is said that a programmer can't write in a day 100 Line code ？）. Last , In fact, when looking at the new code, first look at the data , It also helps to understand the code （ Maybe the longest file is where the core logic is ？）. therefore , We'll be fine in the future tokei For a second .
All right, no nonsense , First, install it directly cargo Just fine ：
Let's take cpython The source code of , look down tokei How to use it
Use it directly tokei+ Directory name can get the number of files classified by language under the directory 、 Lines of code （ Including code and comments ） And the number of blank lines .
$ tokei cpython/

Use -s You can sort for a column , For example, if we want to sort for the number of lines of code
$ tokei cpython/ -s code

You can also use --files Make the statistics display by file instead of merging . because cpython Too many files , Let's select a subdirectory to see ：
$ tokei cpython/Parser/ --files

Last , Actually tokei It's a Japanese word , It means clock , Perhaps the author is suggesting that this tool is running very fast . In fact, github And other similar tools （Go Of scc And the same Rust Written loc） Of Compare . But the comparison version is a little old .
Let's run by ourselves to see the current statistics Rust Achievements of the official code base (CPU Time ) Well ：
tokei 1.5±0.1s
scc 2.3±1.0s
loc 3.8±0.4s
tokei Isn't it excellent ？ But don't take it too seriously , It's all a blink of an eye . Nothing much tokei Check out your code ～
