#Get file path ruby code#

Just like we have temp directories, we also have two classes that can be used as temporary file objects, Tempfile and StringIO. This reads the file contents and returns it.

Can’t get much simpler than this.Īnd just as simple is reading a file: contents = IO. This opens the file at /path/to/file.txt, writes the text to it and closes the file. write ( '/path/to/file.txt', 'This is my cool text I need to write! Yay!' ) If all you want is write some text to a file, Don’t use File, use IO directly: IO. Handling files that fit in memory? Use IO directly This also includes the Dir.tmpdir method that gives you the path to your operating system’s temp directory.

join ( dir, 'text.txt' ), 'w' ) endĪlso, always set at least a prefix for your temp folders to make sure you can spot them if they aren’t deleted or if your app crashes and doesn’t remove them for some reason, at least you’ll know which code failed to execute. mktmpdir ( 'my-prefix' ) do | dir | File. It’s a bit hidden since it isn’t part of the main Dir documentation, but it’s there, you can create temporary directories and leave the standard library delete them and it’s contents for you by using Dir.mktmpdir: require 'tmpdir' Dir. You might have heard about Tempfile, but did you know you can create temporary directories in Ruby and it’s built in into the standard library?

Since I always have to go back to the docs to check on most of this stuff, it might just be better to keep it all indexed here so I can just open this blog post instead of going hunting this all again.Īnd, guess what, this could even be helpful for other people as well, right? Temporary directories
