ASCIIANSI

ASCIIANSI is an informal term used to describe the practice of embedding ANSI escape sequences within ASCII text to produce colored and formatted output in text terminals. It bridges the ASCII character set, primarily plain printable characters, with the ANSI escape code system that controls color, style, and cursor movements. There is no formal standard by this name; the concept arises wherever ASCII text is rendered in compatible terminals that interpret ANSI controls.

Background: ASCII is a 7-bit character set defined in early standards; ANSI escape codes originated from the ANSI X3.64 standard and ISO/IEC 6429. Most ANSI sequences begin with the Escape character followed by the left square bracket, then numeric parameters, and a final letter. The SGR (Select Graphic Rendition) command is the subgroup used to set text color and attributes; for example, codes that turn text red or bold, and resetting to defaults.

Usage and scope: ASCIIANSI-style text appears in terminal demos, archival ANSI art, colorized log files, and interfaces that run in capable terminal emulators. It is also used in some chat logs and developer demonstrations. However, support varies across environments; some terminals strip or ignore escape codes, and some contexts require escaping or removing ANSI sequences for plain-text users. It can also increase file size and complicate version control and diffs.

Relation and modern relevance: While ANSI escapes remain widely supported in modern terminals, the label ASCIIANSI is not widely used in formal documentation. In contemporary practice, people refer to ANSI colorization or ANSI escape sequences rather than a single standard. Related topics include ASCII art and ANSI escape codes.
