Is there a better way to write text to a file?

File.open("/file/location/new.txt",“w”) {|file| file.write “data to
write”}

It just seems a bit long winded and unmessy

Thanks

File.copy in this instance, surely?

This isn’t a file copy. I’m just writing data to a file.

This is equivalent :

File.open(“/file/location/new.txt”,“w”) {|file| file << “data to write”}

You can always write like:

file = File.open("/file/location/new.txt",“w”)
file.write “data to write”
file.close

But there is no ruby fun there.

You can always write like:

Or you can make this way:

File.open(“test.txt”,“w”) {|file| file << “data to write”}

Are you sure you mean unmessy? :slight_smile: In any case – I agree, it does
have a bit of overhead, and always seems like a lot to write when just
writing one thing. It pays for itself when the block contains more
logic, of course.

You could do:

(File.open(“file”,“w”) << data).close

though that makes the writing seem kind of side-effect-esque.

Oops. That’s what I get for not drinking coffee before replying. :slight_smile:

This isn’t a file copy. I’m just writing data to a file.

This is equivalent :

File.open(“/file/location/new.txt”,“w”) {|file| file << "data

to write"}

have you tried rio?

require “rio”
rio(“/file/location/new.txt”) << astring

kind regards -botp

What would you prefer?

Ruby is quite flexible, so if you start with how you’d like it to
work, you can probably get close. For example (I’m not recommending
these, but if you’re looking for brief):

w “/tmp/foo.txt”,“data to write”

or

“data to write”.w “/tmp/foo.txt”

or

“/tmp/foo.txt”.w “data to write”
