Pro Syntax highlighting for a wide variety of languages
Notepad++ has built-in support for syntax highlighting for a wide selection of programming languages.
Pro Light and fast
Notepad++ is a very light program that starts almost instantly. This makes it a great text editor for users that want something that will start the second they open it.
You can get a portable version of N++ and put it on a flash drive or your dropbox account and have your editor, configured the way you like, at any computer that you are on.
Pro Extendable via plugins
A list of hundreds of plugins is maintained.
Pro Free under GPL
Notepad++ is licensed under GPL, which means it is free/open source software that you can use freely.
Pro Regex replace in selection, active tab, or all tabs
In Notepad++, the user can utilise regular expressions to quickly modify text across multiple files.
Pro Persistent documents, even after exiting the application
If you close Notepad++ (npp), your documents remain even if you haven't saved.
Pro Split screen
The user can open and edit files in multiple screens within the editor window.
Pro Multi-line editing
While it is disabled by default, when enabled, it is possible to edit more than one line at a time. This is helpful in many situations.
Pro Easy to use and admin
Very easy to use and personalize.
Pro User defined language syntax support
You can define your own custom syntax highlighting rules (or add support for others) .
Pro Supports Markdown
If you have the Plugin Manager installed you can search for MarkdownViewer++ and install it via that plugin.
Pro Advanced coding of HTML templates with validation and auto-complete
Integrated usage of the angular-CLI for Angular best practices.
Pro TypeScript 2.x validation and debugging
While it can run in Wine, it is native only to Windows. Linux users will have to use Notepadqq instead.
Con Outdated UI
Only the text area can be themed, and it doesn't have as many features as browser-based text areas.
Con Limited new syntax support for new languages
It may be hard to find good plugins for relatively new languages.
Con Settings confusingly scattered
Examples: try to change the tab size or used font.
Con Session backups not enabled by default
Unsaved tabs will be lost when Npp crashes, unless you first enable the session backup option.
Con User defined language doesn't support triple quote strings
It also doesn't support triple hashed comments. Both styles are overridden by their single character single line version.
Con Annoying update notifications upon start-up
Annoying update notifications tend to pop up upon start-up after not having used the app or machine for a few days. At the same time, they can be easily turned off.
Con Very slow
Slower as compared to other editors/ides like VScode, Sublime, Comodo.
Gives only 8 days per month to use all features like automatic imports, code formatting and so on.
