Sublime Text vs Spacemacs

Sublime Text is very lightweight by default. Customization occurs on the fly thanks to Package Control.

Sublime Text has a minimap on the side that provides a top-down view of the file and keyboard shortcuts for most actions. It also supports a large number of languages and general text editing features out of the box.

Multiple cursors and column selection allows for versatile ways of editing.
ctrl + d will select the current word and each time the command is repeated, it adds the next occurrence of the word to the selection.
ctrl + click or middle-mouse click will place another cursor in the place that's clicked. Cursors can then be controlled together. This also permits selecting vertically.
ctrl + shift + l will place a cursor on every highlighted line.

Sublime Text uses TextMate's syntax declaration files to support new languages, it has all its menus and keybindings generated from JSON files, and it can be scripted to add new features using Python.
If Sublime Text doesn't support a desired language or feature, it's usually not long before someone implements it themselves - examples include the plugin package manager and the 'open in browser' command.

When you start using Sublime Text, it doesn't drown you in keyboard shortcuts or non-intuitive use-concepts. However, high-level functionality can still be easily accessed when the need for it arises.

Sublime Text looks consistently the same across Windows, OS X, and Linux.

Sublime Text allows for all sorts of customization to help users change almost everything in the editor: Key Bindings, Menus, Snippets, Macros, Completions, and many more. Essentially, just about everything in Sublime Text is customizable with simple JSON files. This system gives the user flexibility as settings can be specified on a per-file type and per-project basis.

Sublime is quick to start and never slows down. The UI is always responsive and you know what is happening in the background.

The package manager is a plugin and can be swapped with something else custom.

Sublime Text, while being lighter-weight than an IDE, still supports many IDE features.

• Text from the current file is used to provide autocomplete.
• Project Support (folder browsing, scoped history, build-system declarations).
• Refactoring support is emulated through multi-select, project-wide find and replace, and regular expression search.
• Syntax-aware selection and GoTo for quickly jumping to locations in the project.
• Snippets and Macros.
• A Python console for everything else.

Command Palette allows for fuzzy searching all available settings, snippets, etc.

All you need to do when starting up is to install a package manager and modify user configuration.

Regex commands help describe a certain amount of text.

From menus to commands, assign key maps to almost anything.

Settings are modular and can be shared.

Distraction free editing takes over your screen and removes every UI element so you can focus on code.

Choose from many build systems or craft your own.

A Sublime license can be bought but it can still be used for free. However, a pop-up appears when you save multiple times.

Open Goto Anything by pressing Ctrl or Command + P and by using fuzzy search you can look for a file in your project. The file will load even without pressing enter, so you can make sure you've found the correct file without committing.

Both of these programming interfaces are cross-platform, open source, and easy to use.

Provides command line shortcut for server upload.

Vintage mode is Vim-style editing that's already built into the text editor.

Sublime Text compatibility with Textmate bundles is good, but excludes commands, which are incompatible. In general, Sublime Text syntax definitions are compatible with Textmate language files (.tmLanguage extension).

Create your own theme with online editor.

With lot of functionalities, where other editor even not think to provide.

Spacemacs combines the Emacs platform (with the full power of the Emacs plugin ecosystem) and the Vi keybindings (via EViL), all in the same box.

At the heart of Spacemacs, the configuration layers group packages configuration into semantic units that can be toggled on and off. The architecture is simple but powerful, allowing the user to easily manage configuration dependencies between hundreds of packages.

Spacemacs is the biggest community-driven Emacs starter-kit.

Documentation is mandatory for each new configuration layer and can be accessed directly within the editor in Org format.

Emacs runs on Gnu/Linux, Mac OS X, and Windows.

Stuff like version control, file management, good default theme are all configured out of the box.

Space-lead key bindings are organized in mnemonic namespaces. For instance, buffer actions are under SPC b, file actions are under SPC f, project actions are under SPC p, search actions are under SPC s, and so on. Keybindings are consistent across the whole distribution thanks to a set of conventions.

There's no need to reach for the mouse again since Spacemacs can be fully controlled with keyboard.

Evil package is a first class citizen and Spacemacs embraces it from day one. Evil package allows Vim users to be productive very quickly while still allowing regular Emacs users to use Spacemacs.

Files can be edited in Spacemacs remotely.

Allows for great organization applications that can be saved in future-proof format, plain text, can be integrated with org, LaTeX, markdown, HTML, Literate Programming and be committed to source control.

Spacemacs has some great features for taking notes, tracking to-do lists, and tracking time.

LaTeX allows for auto-completion, syncing, and more.

Has great daemon support, which can mitigate the issue of slow startup.

Sometimes you only have terminal access, over ssh or something.

Syntax highlighting and org-babel extensions.

The community surrounding Spacemacs is very active and there is a welcoming gitter chat for users to ask questions.

Spacemacs got its name from the fact that it is uses the space bar as a default leader key. The key was chosen because it is easy to press and to hopefully lower the risk of RSI.

New functionalities and fixes are added to Spacemacs every day, while release cycles are short.

Elixir layer which uses the Alchemist package is the best way to edit Elixir code out there.
