25 ;;; Commentary:
27 ;; This file provides a function that takes a string or a region
28 ;; containing Select Graphic Rendition (SGR) control sequences (formerly
29 ;; known as ANSI escape sequences) and tries to translate these into
30 ;; faces.
32 ;; This allows you to run ls --color=yes in shell-mode. It is now
33 ;; enabled by default; to disable it, set ansi-color-for-comint-mode
34 ;; to nil.
36 ;; Note that starting your shell from within Emacs might set the TERM
37 ;; environment variable. The new setting might disable the output of
38 ;; SGR control sequences. Using ls --color=yes forces ls to produce
39 ;; these.
41 ;; SGR control sequences are defined in section 3.8.117 of the ECMA-48
42 ;; standard (identical to ISO/IEC 6429), which is freely available as a
43 ;; PDF file <URL:http://www.ecma-international.org/publications/standards/Ecma-048.htm>.
44 ;; The "Graphic Rendition Combination Mode (GRCM)" implemented is
45 ;; "cumulative mode" as defined in section 7.2.8. Cumulative mode
46 ;; means that whenever possible, SGR control sequences are combined
47 ;; (ie. blue and bold).
49 ;; The basic functions are:
51 ;; `ansi-color-apply' to colorize a string containing SGR control
52 ;; sequences.
54 ;; `ansi-color-filter-apply' to filter SGR control sequences from a
55 ;; string.
57 ;; `ansi-color-apply-on-region' to colorize a region containing SGR
58 ;; control sequences.
60 ;; `ansi-color-filter-region' to filter SGR control sequences from a
61 ;; region.
63 ;;; Thanks
65 ;; Georges Brun-Cottan <gbruncot@emc.com> for improving ansi-color.el
66 ;; substantially by adding the code needed to cope with arbitrary chunks
67 ;; of output and the filter functions.
69 ;; Markus Kuhn <Markus.Kuhn@cl.cam.ac.uk> for pointing me to ECMA-48.
