Ha, haha! Ha! Awesome joke … it’s funny because it’s true! It hurts so much 🙁
I’ve been an emacs user for a while now. Still don’t know all the keyboard shortcuts, text selection still confuses me to no end and I still think the Ctrl+W command to cut is rather unfortunate because I keep clsoing windows in other environments.
But I love Emacs to bits!
The main reason I started using this operating system is that I don’t have to think about code indentation. Almost any language I dare use, Emacs knows how to indent code according to community standards. You might need to install something called a major mode for the language, but hey – package management system!
If you haven’t tried coding without thinking about indentation before, you really should. It’s marvelous, lets you focus on the important stuff.
That said … I always used vim via ssh. Always. Perhaps a remnant from my times before Emacs, when I thought Vim was the default thing you use when working without a GUI. Yes, I’m not a neckbeard, I like my GUI and non-tiling window managers to write code.
Over the past few weeks I’ve been working on a project that frowns upon the idea of working locally – something about data security when dealing with banking-like systems. Whatever.
The only access to my code was the humble ssh. Now fucking what?
Running emacs via ssh -X was painfully slow. Using Vim for more than config editing? Surely, you’re joking [mr. Feynman]!?
After a week of miserably living my life via ssh -X I finally broke down and googled for a solution. Took me long enough … My surprisingly short search (took me all of 10 minutes) discovered something called tramp-mode – a remote-editing mode for emacs.
Since emacs22 it comes bundled with the basic install, so there’s no need to add anything.
It. Is. Amazing.
C-x C-f // and away we go. Enter username@ (lovingly autocompleted by the file finder thingy), add the hostname (also autocompleted). Asks for the password and voila, I’m browsing a remote computer via ssh.
From what I understand, tramp-mode doesn’t actually keep you connected via ssh for live editing on the remote machine. That would be slow, a TCP round-about for every keystroke … no good. Instead it uses scp to copy files locally, let you edit them and when you save the file is copied back into its original location.
For added awesomeness, C-x C-f undestands you’re editing remotely so it always starts finding files relative to the remote location.
Magic. All the flexibility of editing locally, all the whatever-you-need-this-for of secure remote connections.
But I will still edit configs with Vim. It’s only natural.
