我编写了一个 gulp 文件,它监视多个目录的更改,然后创建连接到多个指定的目标。
这是我的项目结构的简化版本:
我有 2 个站点文件夹: 一个 /和两个 /
每个站点都有两个分支文件夹: a/和b/
在每个分支内部,有三个文件夹: inner/、outer/和web/
我的任务是从内部和外部文件夹中获取相似的部分文件,并将它们连接到相关的网络文件夹中。下面是所需输出的简单示例。
-- inner/
|-- color1
|-- color2
|-- fruit1
|-- fruit2
-- outer/
|-- color1
|-- color2
|-- fruit1
|-- fruit2
-- web/
|-- colors.txt
|-- fruits.txt
我创建了一个config.json文件来保存站点特定的配置。目前仅使用它来自定义站点路径。这是config.json
{
"sites": {
"one": {
"a": "/path/to/one/a/",
"b": "/path/to/one/b/"
},
"two": {
"a": "/path/to/two/a/",
"b": "/path/to/two/b/"
}
}
}
最后是gulpfile.js
// Include local Gulp
var gulp = require("gulp");
// Get data from config.json
var sites = require("./config.json").sites;
// Include Gulp specific plugins
var gConcat = require("gulp-concat");
var gHeader = require("gulp-header");
var gUtil = require("gulp-util");
var gNotify = require("gulp-notify");
// Setup directories
var outer = "outer/";
var inner = "inner/";
var web = "web/";
// Misc
var alertMessage = "# GENERATED FILE - DO NOT MODIFY\n\n";
// 8 total tasks for concatenation
// Concatenate to colors.txt - 4 tasks
// Color task 1: [ Site => one ] [ Branch => a ]
gulp.task("one_a_color", function() {
return gulp.src([sites.one.a + outer + "color?", sites.one.a + inner + "color?"])
.pipe(gConcat("colors.txt"))
.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.one.a + web))
.pipe(gNotify());
});
// Color task 2: [ Site => one ] [ Branch => b ]
gulp.task("one_b_color", function() {
return gulp.src([sites.one.b + outer + "color?", sites.one.b + inner + "color?"])
.pipe(gConcat("colors.txt"))
.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.one.b + web))
.pipe(gNotify());
});
// Color task 3: [ Site => two ] [ Branch => a ]
gulp.task("two_a_color", function() {
return gulp.src([sites.two.a + outer + "color?", sites.two.a + inner + "color?"])
.pipe(gConcat("colors.txt"))
.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.two.a + web))
.pipe(gNotify());
});
// Color task 4: [ Site => two ] [ Branch => b ]
gulp.task("two_b_color", function() {
return gulp.src([sites.two.b + outer + "color?", sites.two.b + inner + "color?"])
.pipe(gConcat("colors.txt"))
.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.two.b + web))
.pipe(gNotify());
});
// Concatenate to fruits.txt - 4 tasks
// Fruit task 1: [ Site => one ] [ Branch => a ]
gulp.task("one_a_fruit", function() {
return gulp.src([sites.one.a + outer + "fruit?", sites.one.a + inner + "fruit?"])
.pipe(gConcat("fruits.txt"))
.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.one.a + web))
.pipe(gNotify());
});
// Fruit task 2: [ Site => one ] [ Branch => b ]
gulp.task("one_b_fruit", function() {
return gulp.src([sites.one.b + outer + "fruit?", sites.one.b + inner + "fruit?"])
.pipe(gConcat("fruits.txt"))
.pipe(gHeader(alertMessage))

.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.two.a + web))
.pipe(gNotify());

.pipe(gHeader(alertMessage))
.pipe(gulp.dest(sites.two.b + web))
.pipe(gNotify());
});
// Watch for all events in specified {directories}/{files}, then trigger appropriate task
// 8 total watch jobs
gulp.task("watch", function () {
// Color related watch jobs - Total 4
// Color watch 1: [ Site => one ] [ Branch => a ]
gulp.watch([sites.one.a + outer + "**/color?", sites.one.a + inner + "**/color?"], function(event) {

上面的 gulp 文件工作并完成了这项工作。但是,如您所见,大部分代码都是重复的,只有 gulp.src 和 gulp.dest 以及任务名称发生了变化。
我的问题是。是否有可能简化这个 gulp 文件,而不是为每个任务重复代码,也许可以将类似的任务一起批处理。
