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 to a fixed value
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 mutating function
gulp.src("./src/**/hello.txt")
.pipe(rename(function (path) {
// Updates the object in-place
path.dirname += "/ciao";
path.basename += "-goodbye";
path.extname = ".md";
}))
.pipe(gulp.dest("./dist")); // ./dist/main/text/ciao/hello-goodbye.md
// rename via a map function
gulp.src("./src/**/hello.txt")
.pipe(rename(function (path) {
// Returns a completely new object, make sure you return all keys needed!
return {
dirname: path.dirname + "/ciao",
basename: path.basename + "-goodbye",
extname: ".md"
};
}))
.pipe(gulp.dest("./dist")); // ./dist/main/text/ciao/hello-goodbye.md
// rename via a fixed object
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

Notes
dirname
is the relative path from the base directory set bygulp.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 abase
option, which can be used to explicitly set the base.gulp.dest()
renames the directories betweenprocess.cwd()
anddirname
(i.e. the base relative to CWD). Usedirname
to rename the directories matched by the glob or descendents of the base of option.
basename
is the filename without the extension likepath.basename(filename, path.extname(filename))
.extname
is the file extension including the.
likepath.extname(filename)
.- when using a function, a second
file
argument is provided with the whole context and original file value. - when using a function, if no
Object
is returned then the passed parameter object (along with any modifications) is re-used.
