When comparing Neovim vs PyCharm, the Slant community recommends PyCharm for most people. In the question“What are the best Python IDEs or editors?” PyCharm is ranked 1st while Neovim is ranked 6th. The most important reason people chose PyCharm is:
PyCharm has CVS, Git, Subversion and Mercurial integration.
Ranked in these QuestionsQuestion Ranking
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 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 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 Comes with some good configurations out of the box
Some typical configurations most of VIM users make are default in Neovim.
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 Work in TUI (Tex User Interface)
Neovim can work on terminal, on a remote server over ssh.
Pro Terminal mode is very convenient for testing code in a split window
Pro Version control integration
PyCharm has CVS, Git, Subversion and Mercurial integration.
Pro Catches run-time information when running the code
PyCharm can leverage run-time information when running your application with the built-in debugger to figure out what types can possibly be passed to which functions, etc.
Pro One of the best autocompletion engines around
PyCharm has two types of autocompletion: structural completion and word expansion.
Both types of autocompletion work extremely well, have little to no problems and are quite fast even when loading suggestions on the go.
Pro Free version available
There's a community edition (with limited features) that's free to use. You can also get a 30-day trial of the Professional edition.
Pro Excellent refactoring support
There are many refactoring options including renaming and changing signature across entire projects. It also includes the an ability to preview changes before committing and exclude anything unwanted.
Pro Great pip support
PyCharm offers great pip integration. When opening a project it automatically checks for a
requirements.txt file in the root of the project. If it's found, it checks if all the libraries are available in the interpreter. If one or more libraries are missing, it issues a warning and asks whether you want to install any missing libraries.
Pro Excellent integration with debugging tools
All the debugging can be done inside the IDE. Breakpoints in the code can be added using keyboard shortcuts or the mouse. When the code is executed through the debugger a toolbar pops up with all the relevant context needed for the debugging process.
The whole process is smooth and painless and you don't even have to switch windows to do the debugging.
Pro Great for navigating large codebases
PyCharm has amazing code navigation implementations. It supports both goto symbol and goto declaration. The former finds classes, variables, functions, etc by name. While the latter is used by moving the cursor on top of a symbol and by using the mouse or a keyboard combination it finds the declaration of that symbol and takes you there.
Both of these features are extremely helpful when consulting large code-bases and when trying to understand an API written by someone else.
Pro Built-in Django support
Pycharm has excellent django support, from templating to management commands, it has it all.
Pro Supports installing third party libraries
No need to go to the command line to download a new package, PyCharm has an easy system to browse, download, and update third party packages.
Pro Automatically figures out what test to run based on the method the cursor rests at a given time
PyCharm, based on what method or class the cursor rests, can figure out what tests to run and perform them with a keyboard shortcut or two, without breaking up the flow and need to switch to a command line interface.
Pro Sophisticated static analysis tools
Pro Vim mode for people used to Vim commands
IdeaVim supports motion keys, insert mode commands, marks, registers, visual mode commands, vim regexps, key mapping, macros, digraphs, some ex and :set commands. You can find a full comparison in the IdeaVim reference manual.
Pro Remote debugging over ssh coupled with automatic deployment creates a streamlined workflow
The professional version allows remote debugging over ssh, which together with automatic deployment creates a streamlined workflow.
Pro Free student access to Professional Edition
With a valid .edu address students can register to use the Professional edition and enjoy all the perks of the full paid version for free.
Though it should be mentioned that the with the free student acess you cannot use PyCharm for any commercial purposes, even accepting donations for an open source project.
Pro Easy to optimize code with built-in profiling tools
If you have a yappi profiler installed on your interpreter, PyCharm starts the profiling session with it by default, otherwise it uses the standard cProfile profiler.
Con No graphical editor yet
At the time of writing this, no equivalents to gVim exist.
Con No stable release yet
As of yet, Neovim is in an unstable point in it's development. There is no stable release and using it for the moment should be done with caution as many features may change in the future.
Con Limited cross platform support
Neovim is not available for many legacy platforms.
The Windows version is currently considered experimental.
Con Ambiguity in extensive documentation
Con Why clone Vim
You can use Vim and plugins.
Con Very high memory usage
Con Vim mode is limited
Con Not suitable to edit project's files written in other languages
Con Rendering is awful
Con Some relatively basic functionality requires paid license
Con Does not support inline plots
Spyder supports the inline plot function of matplotlib, not the case for PyCharm.
Con Assinine licensing scheme
JetBrains licensing, especially if you have multiple products, is a blocker. You just can't a fixed line-item price (for departmental budgeting) for their licenses.
Con Can not be integrated with external linters, like Pylint, Flake8, etc.
Sublime Text has SublimeLinter, Vim has Syntastic, PyCharm has nothing.
Con It cannot reindex on the fly packages installed from git source
If you've installed a package with the command:
pip install -e git+https://firstname.lastname@example.orgemail@example.com#egg=package
you have two options available to make PyCharm update/see it:
- restart PyCharm
- invalidate caches
Con Sometimes all autocomplete stuff dies with over 9k Java exceptions with no visible reason
Con Odd Autosave "feature", can't be disabled fully
PyCharm automatically saves your files for you, always, without telling you. You can't disable this. There's a way to indicate if a file has been modified via an indicator in the tab (not enabled by default - why?).
If you exit it won't ask you if you want to save the modified file. Totally unintuitive and contrary to all other established workflows. It's ok to try something new, but give users the option to have the "normal" behaviour of any other IDE/editor out there. Can be a deal breaker for those that need to know/have control over when they save their files. (PyCharm offers a history to undo the automatic save, but why force a user to undo something with extra steps that shouldn't have happened in the first place?)
