gulp iconfont

参考如下网站

https://github.com/hjzheng/CUF_meeting_knowledge_share/tree/master/2015-7-24/gulp-test-iconfont

gulpfile.js

var gulp = require('gulp');
var iconfont = require('gulp-iconfont');

var iconfontCss = require('gulp-iconfont-css');

var template = require('gulp-template');
var fs = require('fs');

var icons = fs.readdirSync('src/style/svg');

icons = icons.map(function(icon) {
    return icon.replace(/\.\w+$/, '');
});

var cssName = 'iconfont'; //生成的css名称
gulp.task('icon', function() {
    let dirname = 'src/style';
    return gulp
        .src([`${dirname}/svg/*.svg`])

        .pipe(
            iconfontCss({
                fontName: 'iconfont', // iconfont.css的font-family值
                path: `${dirname}/template/iconfont.template.less`, //css模版文件
                targetPath: `../${cssName}.css`, //css生成文件
                fontPath: 'fonts/' //iconfont.template.less文件中的fontPath
            })
        )
        .pipe(
            iconfont({
                fontName: 'iconfont',
                formats: ['svg', 'ttf', 'eot', 'woff', 'woff2'],
                normalize: true
            })
        )
        .pipe(gulp.dest(`${dirname}/fonts`)); //svg的字体文件存放位置
});

gulp.task('example', function() {
    let dirname = 'src/style';
    gulp.src(`${dirname}/example/index.html`) //样式例子文件
        .pipe(template({ icons: icons, cssName: cssName }))
        .pipe(gulp.dest(`${dirname}`)); //样式例子文件存放位置
});
gulp.task('default', ['icon', 'example']);

iconfont-template.less

执行语句

gulp icon

gulp example

与

gulp.task('example', function() {....
中的task值相同

gulpfile.js文件中增加

　　gulp.task('default', ['icon', 'example']);

　就可以直接gulp生成font，css ，html



=====缺点
生成的font字体 1.只能是黑白色调， 2.svg图片中如果有线条重合，就会被重叠消除为白色【这个问题在icomoon网站中也存在】

=====总结
https://icomoon.io/app/ 这个网站生成font字体，还是不错的


【第一种缺点是没有颜色】

第二种生成iconfont方式【可以有颜色】

gulpfile.js

var gulp = require('gulp');
var rename = require('gulp-rename');
var iconfont = require('gulp-iconfont');
var consolidate = require('gulp-consolidate');

var template = require('gulp-template');
var fs = require('fs');

var icons = fs.readdirSync('src/style/svg');

icons = icons.map(function(icon) {
    return icon.replace(/\.\w+$/, '');
});

gulp.task('icon', function() {
    let dirname = 'src/style';
    return gulp
        .src([`${dirname}/svg/*.svg`])
        .pipe(
            iconfont({
                fontName: 'iconfont1',
                formats: ['svg', 'ttf', 'eot', 'woff', 'woff2'],
                normalize: true,
                options: {
                    fixedWidth: false,
                    normalize: false,
                    // fontHeight: 512,
                    // descent: -32
                },
                // prependUnicode: true // 会修改掉svg的名字
            })
        )
        .on('glyphs', function(glyphs, options) {
            gulp.src(`${dirname}/iconfont.template.1.less`)
                .pipe(
                    consolidate('lodash', {
                        glyphs: glyphs.map(function(glyph) {
                            glyph.unicode = glyph.unicode[0]
                                .charCodeAt(0)
                                .toString(16)
                                .toUpperCase(); // unicode是16进制的
                            return glyph;
                        }),
                        fontName: options.fontName,
                        // glyphs: glyphs,
                        fontPath: 'fonts/'
                    })
                )
                .pipe(rename(`${options.fontName}.css`))
                .pipe(gulp.dest(dirname));
        })
        .pipe(gulp.dest(`${dirname}/fonts`));
});

gulp.task('example', function() {
    let dirname = 'src/style';
    gulp.src(`${dirname}/example/index.1.html`)
        .pipe(template({ icons: icons }))
        .pipe(gulp.dest(`${dirname}`));
});

gulp.task('default', ['icon', 'example']);

iconfont-template.less
中循环语句修改

<% _.each(glyphs, function(glyph) { %>
.icon-<%= glyph.name %>:before {
    /* content: "\<%= JSON.stringify(glyph) %>";*/
    content: "\<%= glyph.unicode %>";
    <%= glyph.color?'color:'+glyph.color :null %>
}
<% }); %>
