Using this setup, the user writes definitions that affect the Racket runtime. The default editor when learning Racket is DrRacket, which has a Definitions panel at the top and an Interactions panel at the bottom. Racket is an exciting emerging Lisp dialect with a dynamic programming environment, a GUI toolkit, and a passionate community. To try the Emacs terminal, type Alt+ x ( M-x in Emacs notation), then type shell, and press Return. Easy copying and pasting if no system clipboard is available: Whether I'm too lazy to move my hand from the keys to the mouse, or I don't have mouse functionality because I'm running Emacs in a remote console, having a terminal in Emacs can sometimes mean a quick transfer of data from my Emacs buffer to Bash.It's a small but significant advantage to have a terminal just a Ctrl+x+o (or C-x o in Emacs notation) away, and it's especially nice to be able to glance over at it for status reports when it's running a lengthy job. Opens in an Emacs buffer: I use Emacs' Elisp shell because it's conveniently located in my Emacs window, which I often run in fullscreen. ![]() There are lots of terminal emulators available. Although the Elisp terminal emulator in Emacs isn't the greatest general-purpose one, it's got two notable advantages. Intrigued? Read my step-by-step guide about calendaring with Org mode and Git. Pushing changes to your agenda is reflected on your mobile, so you can stay organized even when Emacs isn't available. You can refer to your agenda easily in Emacs, make updates to your schedule, and generally stay on task. Once you've got your infrastructure sorted, though, the process is inherently perfectly integrated with your usual (or developing, if you're a new user) Emacs workflow. The process takes a little setup to create a convenient way to sync your agenda with your mobile device (I use Git, but you could invoke Bluetooth, KDE Connect, Nextcloud, or your file synchronization tool of choice), and you have to install an Org mode viewer (such as Orgzly) and a Git client app on your mobile. If you parse text better than you parse graphical interfaces, you'll be happy to know that you can schedule your day (or life) in plain text with Emacs but still get fancy notifications on your mobile device with open source Org mode viewers. The next time you start to SSH into a server just to launch a Vim or Emacs session, try Tramp instead. Tramp is great for editing files that don't exist on your computer, and the user experience is not noticeably any different from editing a local file. Like Git, Emacs uses your SSH config first and only stops to ask for more information in the event of an error. However, Tramp uses OpenSSH directly, so to avoid interactive prompts, you can also add your hostname, username, and SSH key path to your ~/.ssh/config file. When prompted in the mini-buffer at the bottom of the Emacs window, enter the file name using this syntax: you are required to log in interactively, Tramp prompts you for your password. In the File menu of Emacs, select Open File. Tramp is already included in Emacs 22.1 or greater, so to use Tramp, you just open a file in the Tramp syntax. The most popular and safest protocol for remote editing these days is OpenSSH, so that's the default. The Tramp mode in Emacs (formerly known as RPC mode) stands for "Transparent Remote (file) Access, Multiple Protocol," which spells out exactly what it offers: easy access to remote files you want to edit over most popular network protocols. Use Tramp mode for cloud editingĮmacs has been network-transparent for a lot longer than has been trendy, and today it still provides one of the smoothest remote editor experiences available. Here are six things you may not have realized you could do with Emacs. But if you're a casual Emacs user, you may only be scratching the surface of what it can do for you. ![]() That makes for a powerful user interface (UI). To Emacs, everything is Lisp data, so everything can be analyzed and manipulated programmatically. ![]() In Emacs, there's no separation between the Lisp engine running the application and the arbitrary text you type into it. This is what Emacs does for the 1958 programming language Lisp. ![]() For a Python developer, it's a rich Python environment that can be changed and developed with just a few custom functions in a config file. From the user's perspective, it's the same experience as any text editor. Everything in your text document is a Python object and can be manipulated accordingly. Making a word all capitals, for instance, calls upper(), opening a file calls open, and so on. But every action you perform would be defined by a Python function. You would be able to load files into memory, edit them, and save changes. Imagine using Python's IDLE interface to edit text.
