gulp-rename's Introduction

gulp-rename

gulp-rename is a gulp plugin to rename files easily.

Usage

gulp-rename provides simple file renaming methods.

var rename = require("gulp-rename");

// rename via string
gulp.src("./src/main/text/hello.txt")
	.pipe(rename("main/text/ciao/goodbye.md"))
	.pipe(gulp.dest("./dist")); // ./dist/main/text/ciao/goodbye.md

// rename via function
gulp.src("./src/**/hello.txt")
	.pipe(rename(function (path) {
		path.dirname += "/ciao";
		path.basename += "-goodbye";
		path.extname = ".md"
	}))
	.pipe(gulp.dest("./dist")); // ./dist/main/text/ciao/hello-goodbye.md

// rename via hash
gulp.src("./src/main/text/hello.txt", { base: process.cwd() })
	.pipe(rename({
		dirname: "main/text/ciao",
		basename: "aloha",
		prefix: "bonjour-",
		suffix: "-hola",
		extname: ".md"
	}))
	.pipe(gulp.dest("./dist")); // ./dist/main/text/ciao/bonjour-aloha-hola.md

See test/rename.spec.js for more examples and test/path-parsing.spec.js for hairy details.

Notes

dirname is the relative path from the base directory set by gulp.src to the filename.
- gulp.src() uses glob-stream which sets the base to the parent of the first directory glob (*, **, [], or extglob). dirname is the remaining directories or ./ if none. glob-stream versions >= 3.1.0 (used by gulp >= 3.2.2) accept a base option, which can be used to explicitly set the base.
- gulp.dest() renames the directories between process.cwd() and dirname (i.e. the base relative to CWD). Use dirname to rename the directories matched by the glob or descendents of the base of option.
- KNOWN ISSUE: The base set when using brace expansion may not be what you expect (See yocontra/glob2base#1). Use the base option described above.
basename is the filename without the extension like path.basename(filename, path.extname(filename)).
extname is the file extension including the '.' like path.extname(filename).
