overwrite option in .dest()

[sindresorhus]

It would be useful if .dest() had an option to not overwrite existing files.

Use-case: You build a lot of stuff into a dist folder and you want a task to copy all the files that weren't already processed by the pipeline. Yes you could do some trickery with streams, but this would be much easier.

Could be achieved easily by changing the write mode from w to wx if the option was given.

Does gulp.dest('folder', {overwrite: false}) seem like a fine API?

[sindresorhus]

I think wx will make it throw, at least catch that then, or just fs.exists beforehand.

Yes.

@sindresorhus fs.exists seems like an unnecessary extra system call, I'll catch the wx errors

[jlukic]

Was this implemented?

[kevva]

The issue is still open, so no.

It'd be awesome to see this.

Instead of +1 maybe you should think about sending a pull request...

@nillis, @phillip-haydon This is implemented to master. Guess it won't be backported to 3.x.

All vinyl-fs code is essentially "backported" to 3.x - There are breaking changes so we can't include it as a dependency to gulp but you can change your gulp.src and gulp.dest calls to vinylfs.src and vinylfs.dest calls and stuff will continue to work, but take a look at the breaking changes before you swap everything out.
