Автоформат документа с Notepad ++

Download the "NppAutoIndent" plugin.  In Notepad++:

Plugins → Plugin manager → Available → NppAutoIndent

The "NppAutoIndent" plugin has 'smart' indentation for C-style languages, such as C/C++, PHP, and Java.  It's the first release, so don't expect it to be flawless, and of course it might not be completely to your preferences.  There is NO support for HTML/XML and such, maybe later, tag matching is much more difficult to implement.  To use it, select your code and:

TextFX → TextFX Edit → Reindent C++ code

If you cannot see TextFX in your menu, you can install its plugin from SourceForge.

For JavaScript, the JSTool plugin will do this job.

Для разметки / xml есть плагин под названием «Инструменты XML».

Это можно добавить через менеджер плагинов в Notepad ++.

Here are most of plugins to format your code.

JStool (JSmin):
UniversalIndentGUI ( Enable text auto update' in plugin manager-> UniversalIndentGUI
Shortkey = CTRL+ALT+SHIFT+J )

TextFX : ( Shortkey = CTRL+ALT+SHIFT+B or TextFX > TextFX Html Tidy > Tidy: reindent XML) TextFX has the benefit of wrapping long lines, which XML Tools does not do, but doesn't indent those new lines correctly.

XML Tools : (customized plugin for XML; Shortkey = CTRL+ALT+SHIFT+B or XML Tools > Pretty print [Text indent])
XML Tools complements TextFX by indenting the newly wrapped lines nicely.
