Editing Notepad++ (section)

== Features ==
Notepad++ is a [[source code editor]]. It features [[syntax highlighting]], [[code folding]] and limited [[autocompletion]] for [[Programming language|programming]], [[Scripting language|scripting]], and [[markup language]]s, but not [[intelligent code completion]] or syntax checking. As such, it may properly highlight code written in a supported scheme, but whether the syntax is internally sound or compilable, cannot be verified.<ref name="so2015ds"/><ref name="udf">{{cite web |url= http://docs.notepad-plus-plus.org/index.php?title=User_Defined_Language_Files |title=User Defined Language Files |work=notepad-plus-plus.org |access-date=10 November 2015 |archive-url= https://web.archive.org/web/20161223212433/http://docs.notepad-plus-plus.org/index.php?title=User_Defined_Language_Files |archive-date=23 December 2016 |url-status=dead}}</ref><ref>{{cite news |last=DeCarlo |first=Matthew |title=Download of the Week: Notepad++ |website=TechSpot |date=26 May 2009 |url= http://www.techspot.com/news/34846-Download-of-the-Week-Notepad.html |access-date=1 October 2009}}</ref><ref name="Features">{{cite web |url=https://notepad-plus-plus.org/features/ |title=Notepad++ Features |publisher=notepad-plus-plus.org |access-date=10 November 2015 |archive-url= https://web.archive.org/web/20130624005854/http://notepad-plus-plus.org/features/ |archive-date=24 June 2013 |url-status=dead}}</ref> As of version 7.6.3, Notepad++ can highlight the elements of 78 syntaxes:

The language list also displays two special-case items for ordinary [[plain text]]: "Normal text" (default)  or "[[MS-DOS]] Style", which tries to emulate [[DOS]]-era text editors.

Notepad++ has features to consume and create [[Cross-platform software|cross-platform]] [[plain text]] files. It recognizes three [[Newline#Representation|newline representations]] ({{mono|CR}}, {{mono|CR+LF}}, and {{mono|LF}}) and can convert between them on the fly. In addition, it supports reinterpreting plain text files in various [[character encoding]]s and can convert them to [[ASCII]], [[UTF-8]] or [[UCS-2]]. As such, it can fix plain text that seem gibberish only because [[Bush hid the facts|their character encoding is not properly detected]].

Notepad++ also has features that improve plain text editing experience in general, such as:
* [[Autosave]]
* Finding and replacing strings of text with [[regular expression]]s
* Searching text strings within opened tabs
* Searching text strings in a directory
* Guided indentation
* Line bookmarking
* [[Macro (computer science)|Macros]]
* [[Simultaneous editing]]<ref>{{cite web|url=https://notepad-plus-plus.org/features/multi-editing.html|title=Notepad++ Multi-editing|access-date=17 June 2016|archive-date=9 August 2016|archive-url=https://web.archive.org/web/20160809222901/https://notepad-plus-plus.org/features/multi-editing.html|url-status=dead}}</ref>
* [[Split screen (computer graphics)|Split screen]] editing and synchronized scrolling

=== Internationalization ===
Notepad++ supports internationalization through XML files in an application-specific format containing all internationalized strings (dialog captions, menu titles and items, etc.) in a certain language; this file can be reloaded from the application settings. Translations to new languages can thus be written by simply editing an existing file.
