NeoVim was a complete rewrite of Vim, with new features added and underlying issues resolved thanks to the Vim code base. The keybindings and configuration are the same as Vim, so the switch can be pretty simple.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Extensive list of packages
Atom has a built-in package manager and an extensive list of packages.
Pro Built-in package management
Atom was built from the ground up with the community in mind. Package management is therefore a first class feature.
Pro Multiplatform
Atom can run on Mac, Windows, and Linux.
Pro Extendable
Due to its modular design, almost any aspect of the editor can be changed. Even seemingly core packages, like those taking care of search and replace functionality, can be forked on GitHub, and changed and replaced in the editor.
The documentation for creating new plugins is also great, making it easier for developers to jump in and create plugins for Atom.
Pro Free and open source
Atom is free, open source, and written in C++, LESS, and CoffeeScript.
Pro Beginner friendly
One of the goals of Atom is to be a text editor for both experienced and beginner programmers. You can add keyboard shortcuts, change themes, install plugins, and change core settings by clicking through a GUI, or by manually editing config files the old-fashioned way. It has the added advantage of being built using the same engine that powers Google Chrome, so actions like opening and closing tabs feel familiar, even to new or non-programmers.
Pro Embedded Git control
Atom will highlight folders, files, and lines that have any uncommitted edits made. It also integrates really well with GitHub.
Pro Multi-line select and edit
Multiple cursors and column selection allow 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 allows for selecting vertically.
Pro Command Palette support
The Command Palette permits fuzzy searching all available functions, settings, snippets, etc.
Pro Allows for instant file switching
By pressing Ctrl or Command + T and using fuzzy search, you can look for a file in your project.
Pro Themes
You can theme and customize Atom to your liking.
Pro Command line integration out of the box
Installing Atom adds two command line commands - atom
and apm
. The first one runs the application itself while the second is the Atom Package Manager that's used to add and remove various components from the package listing. While these features can be set up with other editors as well, Atom takes care of them out of the box.
Pro HiDPI support
Atom has built-in HiDPI support with zero scaling issues.
Pro Modern feel and very customizable and extendable
Pro Vim plugin turns Atom into a modernized vim
Pro Best support for Arduino with Platformio
Arduino is the most important platform for developing embedded systems.
Pro Could also be used as an IDE
Atom qualifies to be a good IDE because of the packages like linters, atom browser and hydrogen.
Pro Still Vim but with upgraded features and some issues fixed
NeoVim was a complete rewrite of Vim, with new features added and underlying issues resolved thanks to the Vim code base. The keybindings and configuration are the same as Vim, so the switch can be pretty simple.
Pro Better integration with external tools
The core text editor is "headless", meaning it's detached from the user-interface so other programs can hook into it. This enables better integration with IDEs and browsers, where "Vim mode" has typically been a poor substitute because it was a partial rewrite or a partial port at best. One of the advantages of Vim has always been ubiquity and Neovim makes it even more ubiquitous.
Pro Powerful plugin model
Vim plugins have always been useful, but tied to specific languages. Neovim's architecture provides better separation between plugins and the core product, so that plugins are completely flexible and can be written in any language.
Pro Built-in terminal emulator
This avoids the user having to make any installations.
Pro UI Agnostic
The core functionality is handled apart from the UI, meaning that Neovim can be embedded into any other GUI system, such as Atom.
Pro Async plugin execution
Pro Active development community
Pro Opens a 3Gig Text File in a few seconds
Not many editors can open such a large text file so quickly.
Pro Fast and light on memory usage
New neovim editor instance starts instantly and you can have multiple editors open at the same time, because id does not require a lot of memory to run.
Pro Easier to pick-up than ever
Don't believe it? Try typing vimtutor in your command line right now.
Pro Work in TUI (Text User Interface)
Neovim can work on terminal, on a remote server over ssh.
Pro Modern code base
As a refactor over Vim, Neovim has greatly improved its code base. For example, some functionality is handled by libuv, the same code base that powers Node.js.
Pro Comes with some good configurations out of the box
Some typical configurations most of VIM users make are default in Neovim.
Pro Even more powerful since 2019, because of additions such as vim-coc, TabNine, fzf, skim
Vim gets stronger every time command-line tools get stronger. This isn't even it's the final form.
Pro Config file is where it should be
I don't like having dotfiles or dotdirs in my homefolder unless they're needed. Configs should be in the .config
dir in their respective folder.
Pro Built-in file-explorer and ability to make splits and edit multiple things simutaneously.
This makes editing multiple files at once, moving code around so easy.
Pro Treesitter and LSP
Pro Terminal mode is very convenient for testing code in a split window
Cons
Con Very slow startup time
Atom is very slow to startup, which is a big disadvantage if you are accustomed to using it to make quick changes on your files.
Con High memory usage
Atom has a relatively high memory usage, especially when compared to some other text editors not based on Electron. For those who develop on the go, this also tends to mean shorter battery life.
Con Has difficulty with large text files
Tends to crash or hang with large >(10MB) text files, making it less useful as a general text editor.
Con Slows down exponentially with plugins
Extending it needs sacrificing responsiveness.
Con Not suitable for older computers
Atom requires a lot of system resources to run, so it will most probably be painfully slow on an older machine.
Con Doesn't handle RTL (right-to-left text) well
Text can't be highlighted and manipulated properly, cursor isn't displayed visually according to where it is logically (you have to type to find out), and similar issues.
Con Indent errors
Sometimes, especially when given a file that has different indentation that the current setting, the programm seems to get confused.
Con Not known when a new window will open
It's not really clear why and when a new window is opened when you open a file out of the tree view.
Con No text UI
Con Bloated - too many packages, too little productivity
Unable to use package to even convert a C file to PDF.
Con Slow because of Electron
Atom is not a native application. As such performance is subpar and the lag is especially noticeable on larger projects. It also opens a surprising amount of sub-processes and leaks a considerable amount of memory.
Con Crash and data loss
Repeated data loss when the app crashes.
A bugreport about that was closed automatically after some time, nobody cares.
Con Missing additional touches
As Atom is still relatively new, it's missing nice little touches that other text editors have implemented over the years. From simple ease-of-use items like middle-mouse button multi-cursor select, to the ways pasted information from a spreadsheet is interpreted in multi-select situations.
Con Doesn't recognize some keyboards
Con Poor feature discoverability
Con High effort to customize
A lot of time and effort is put in to make it specific to your needs.
Con Requires Brain Mode Switching
When editing in vim, you have you use the vim keys; when editing in every other window on your PC, or in Word or Excel or other application, you need to use the standard system key combinations. Learning the vim combinations can actually make you SLOWER at everything else.
Con Consume brain energy for editing that should be used for logic
Text editing in vim can be great once you've learned it, but it requires thinking about combination of commands. In other editors, you don't have to think about how to delete this part of code. You just think about how to implement a feature, what is a good design for this code. Even after you get used to using vim, it still requires your brain for editing.
Con Ambiguity in extensive documentation
Con Limited cross platform support
Neovim is not available for many legacy platforms
Con Split the VIM community
Moolenaar to be blamed for. If he opened up the development for vim to other bright minds, no fork would have happened. As it is mostly compatible with vim, it is not such a big issue.
