CSS 压缩

基于 nom 的 CSS 压缩库。该库解析 CSS 输入，压缩它并对其应用一些依赖级别的优化。

use css_minify::optimizations::{Minifier, Level};
fn main() {
    assert_eq!(
        Minifier::default().minify(
            r#"
                 #some_id, input {
                     padding: 5px 3px; /* Mega comment */
                     color: white;
                 }
                 
                 
                 /* this is are test id */
                 #some_id_2, .class {
                     padding: 5px 4px; /* Mega comment */
                     Color: rgb(255, 255, 255);
                 }
             "#,
            Level::Three
        ),
        Ok("#some_id,input{padding:5px 3px;color:white}#some_id_2,.class{padding:5px 4px;color:#fff}".into())
    )
}

也有网络版本 https://css-minify.panfilov.tech/

css-minify 库的 CLI 封装。

css-minifier 0.1

USAGE:
    css-minifier [OPTIONS] --input <input>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -i, --input <input>      css which will be minified
    -l, --level <level>      Optimization levels:
                                 0 - Without optimizations 
                                 1 - Remove whitespaces, replace `0.` to `.` and others non
                             dangerous optimizations

                             In mostly cases it's non dangerous optimizations, but be careful
                                 3 - Level Two + merge @media and css blocks with equal
                             screen/selectors. It is a danger optimizations, because ordering of
                             your css code may be changed.
