The etags files consists of multiple sections—one section per input source file. Sections are plain-text with several non-printable ascii characters used for special purposes. These characters are represented as underlined hexadecimal codes below. A section starts with a two line header (the first two bytes make up a magic number):
It is almost never used for this purpose today. Various printable characters are used as visible "escape characters", depending on context. The substitute character was intended to request a translation of the next character from a printable character to another value, usually by setting bit 5 to zero. This is handy because some media (such as ...
Stands for Easy Editor, is part of the base system of FreeBSD, along with vi. [27] Free software: nvi (Installed as vi by default in BSD operating systems and some Linux distributions) – A free replacement for the original vi which maintains compatibility while adding some new features. BSD-3-Clause: vi [9] [10] [28]
The code of MayaVi has nothing in common with that of Autodesk Maya or the Vi text editor. [2] The latest version of MayaVi, called Mayavi2, is a component of the Enthought suite of scientific Python programs. It differs from the original MayaVi by its strong focus on making an interactive program and a reusable component for 3D plotting in Python.
Edits were verified by typing a command to print a small section of the file, and periodically by printing the entire file. In some line editors, the cursor could be moved by commands that specified the line number in the file, text strings (context) for which to search, and eventually regular expressions. Line editors were major improvements ...
Generally, an escape character is not a particular case of (device) control characters, nor vice versa.If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one.
vi (pronounced as distinct letters, / ˌ v iː ˈ aɪ / ⓘ) [1] is a screen-oriented text editor originally created for the Unix operating system. The portable subset of the behavior of vi and programs based on it, and the ex editor language supported within these programs, is described by (and thus standardized by) the Single Unix Specification and POSIX.
Box-drawing characters therefore typically only work well with monospaced fonts. In graphical user interfaces, these characters are much less useful as it is more simple and appropriate to draw lines and rectangles directly with graphical APIs. However, they are still useful for command-line interfaces and plaintext comments within source code.
