Copy all files but change the name of some automatically in yeoman - yeoman

Question

I am trying to create a yeoman generator where I have to copy from templatePath to destinationPath some files and folders, but I would want to have some of this files with a variable that yeoman could change by one of the user's inputs.
like: "<%=name%>-plugin.php" -> "hello-plugin.php"
I saw some references that this can be done but I can't find how.
I am doing right now:
//Copy the configuration files
app: function () {
this.fs.copyTpl(
this.templatePath('**'),
this.destinationPath(),
{
name: this.props.pluginName,
name_function: this.props.pluginName.replace('-', '_'),
name_class: this.props.className,
description: this.props.pluginDescription
}
);
}
I thought that with that code my <%=name%> would magically changed on copyTpl but it doesn't work

Answer 1

I've just found the solution:
Use this.registerTransformStream(); to pipe all files through some node.js script.
var rename = require("gulp-rename");
//other dependecies...
module.exports = yeoman.Base.extend({
//some other things generator do...
writing: function() {
var THAT = this;
this.registerTransformStream(rename(function(path) {
path.basename = path.basename.replace(/(666replacethat666)/g, THAT.props.appName);
path.dirname = path.dirname.replace(/(666replacethat666)/g, THAT.props.appName);
}));
this.fs.copyTpl(
this.templatePath(),
this.destinationPath(), {
appName: this.props.appName
});
}
});
I'm using here gulp-rename to change file names to something else.
Assuming that this.props.appName == "myFirstApp", this:
666replacethat666-controller.html
will change its name to
myFirstApp-controller.html

Following #piotrek answer, I made a function to replace all props with some pattern (like ejs does) -> $$[your prop name]$$. warning: ES6 inside
var rename = require("gulp-rename");
//other dependecies...
module.exports = yeoman.Base.extend({
//some other things generator do...
writing: function() {
this.registerTransformStream(rename((path) => {
for (let prop in this.props) {
let regexp = new RegExp('\\$\\$' + prop + '\\$\\$', 'g')
path.basename = path.basename.replace(regexp, this.props[prop]);
path.dirname = path.dirname.replace(regexp, this.props[prop]);
}
}));
this.fs.copyTpl(
this.templatePath(),
this.destinationPath(), {
appName: this.props.appName
});
}
});
Example:
Let's assume you have this.props.appname = MyApp and this.props.AnotherProps = Test and you want to rename file or folder.
Name your file or folder MyFile$$appname$$.js -> MyFileMyApp.js
Name your file or folder $$appname$$.js -> MyApp.js
Name your file or folder $$AnotherProps$$.js -> Test.js

This is not possible anymore. The feature was bloated and was removed at some point in 2015.
For now, just rename the file:
this.fs.copy('name.js', 'new-name.js')
