Comparison of text editors

This article provides basic comparisons for notable text editors. More feature details for text editors are available from the '' Category of text editor features'' and from the individual products' articles. This article may not be up-to-date or necessarily all-inclusive.

Feature comparisons are made between stable versions of software, not the upcoming versions or ''beta'' releases – and are exclusive of any add-ons, extensions or external programs (unless specified in footnotes).

Overview

Operating system support

This section lists the operating systems that different editors can run on. Some editors run on additional operating systems that are not listed.

Cross-platform

Natural language (localization)

Document interface

Notes

*Multiple instances: multiple instances of the program can be opened simultaneously for editing multiple files. Applies both for single document interface (SDI) and multiple document interface (MDI) programs. Also applies for program that has a user interface that looks like multiple instances of the same program (such as some versions of Microsoft Word).
*Single document window splitting: window can be split to simultaneously view different areas of a file.
*MDI: Overlappable windows: each opened document gets its own fully movable window inside the editor environment.
*MDI: Tabbed document interface: multiple documents can be viewed as tabs in a single window.
*MDI: Window splitting: splitting application window to show multiple documents (non-overlapping windows).

Basic features

Programming features

Notes

* Syntax highlighting: Displays text in different colors and fonts according to the category of terms.
* Function list: Lists all functions from current file in a window or sidebar and allows user to jump directly to the definition of that function for example by double-clicking on the function name in the list. More or less realtime (does not require creating a symbol database, see below).
* Symbol database: Database of functions, variable and type definitions, macro definitions etc. in all the files belonging to the software being developed. The database can be created by the editor itself or by an external program such as ctags. The database can be used to instantly locate the definition even if it is in another file.
* Bracket matching: Find matching parenthesis or bracket, taking into account nesting.
* Auto indentation: May refer to just simple indenting to the same level as the line above, or intelligent indenting that is language specific, e.g., ensuring a given indent style.
* Compiler integration: Allows running compilers/linkers/debuggers from within editor, capturing the compiler output and stepping through errors, automatically moving cursor to corresponding location in the source file.

Extra features

Large file support:

In general, most text editors do not support large text files. Some restrict themselves to available in-core RAM while others use sophisticated virtual memory management techniques and paging algorithms.''Comparison of Windows Text Editors for Large Files''

Search in files:
Perform search (and possibly replace) in multiple files on disk, for example on a sub-directory and recursively all the directories below it.
Similar to grep.

Key bindings

Support for custom key bindings.

Notes, bugs

* Vim: custom maps of Ctrl-1 .. Ctrl-9, Ctrl-0 cannot be set, nor is Control-Shift-<char> distinguished from Ctrl-<char>.
* Notepad++: custom shortcuts of Shift-<char> cannot be set, they need an added modifier such as Ctrl or Alt. i.e. SCI_LINESCROLLUP cannot be bound to "Shift-I"as the "Add"button is greyed out.
* Emacs and Pico: pico uses most of Emacs's motion and deletion commands: ^F ^B ^P ^N ^D etc.

Protocol support

Support for editing files over a network or the Internet.

Unicode and other character encodings

To support specified character encoding, the editor must be able to load, save, view and edit text in the specific encoding and not destroy any characters. For UTF-8 and UTF-16, this requires internal 16-bit character support.

Partial support is indicated if: 1) the editor can only ''convert'' the character encoding to internal (8-bit) format for editing.
2) If some encodings are supported only in ''some platforms''.
3) If the editor can only ''display'' specific character set (such as OEM) by loading corresponding font, but does not support keyboard entry for that character set.

Right-to-left and bidirectional text

Support for Right-To-Left (RTL) texts is necessary for editing some languages like Arabic, Persian, Hebrew, and Yiddish and the mixture of left to right (LTR) and RTL known as bi-directional (BiDi) support.

Depending on the algorithm used in the programs it might only render the bidirectional text correctly but may not be able to edit them. (e.g. Notepad++ 5.1.3 shows bidirectional texts correctly but cannot edit it and user should change the text direction to RTL to be able to edit RTL texts correctly.)
