Raw Normal View History

(ansi-color-process-output): Use markers instead of positions for start and end of region. (ansi-color-apply-on-region): Rewrote code to make it more robust. Previously, occasional mistakes happend when fontifying many chunks of output (eg. ls --color=yes /dev). This happened whenever an overlay was created up to the end of the region, which coincided with the process-mark. New text would then be added within that overlay instead of after it. (ansi-color-make-extent): Overlays are created with the property `modification-hooks' set to '(ansi-color-freeze-overlay). (ansi-color-freeze-overlay): New function. When inserting text at the end of the overlay, the overlay will resize. (ansi-color-process-output): Doc change. (ansi-color-unfontify-region): Doc change. No longer installed automatically in font-lock-unfontify-region-function. (ansi-color-apply): Doc change. (ansi-color-apply-on-region): Use extents or overlays instead of text-properties. (ansi-color-make-extent): New function. (ansi-color-set-extent-face): New function. (ansi-color-process): Removed, Emacs and XEmacs both use ansi-color-process-output, now. (ansi-color-process-output): Doesn't return string anymore. It is installed in comint-output-filter-functions for both Emacs and XEmacs, now. (ansi-color-unfontify-region): Simplified code removing variables pos and start-ansi. (ansi-color-apply): Put text-property ansi-color before putting text-property face because ansi-color-unfontify-region is called immediately after the call to put-text-property. (ansi-color-context-region): Doc change. (ansi-color-filter-region): Simplified code. (ansi-color-apply-on-region): Changed start to start-marker, using a marker explicitly. Put text-property ansi-color before putting text-property face because ansi-color-unfontify-region is called immediately after the call to put-text-property. (ansi-color-faces-vector): Doc change. (ansi-color-for-comint-mode): Changed :type property to choice. (ansi-color-last-context): Removed. (ansi-color-process-output): Don't use ansi-color-last-context, as the main functions will store their context now. (ansi-color-context): Doc change. (ansi-color-filter-apply): Rewrote it based on ansi-color-apply. Uses ansi-color-context such that repeated calls will strip partial escape sequences, too. (ansi-color-apply): Simplified code. Colorize end of string if face is not null. Store context in new (FACE STRING) format, such that repeated calls will strip partial escape sequences, too. Append faces to face property using ansi-color-apply-sequence such that cumulative mode actually works. (ansi-color-context-region): New variable. (ansi-color-filter-region): Rewrote it based on ansi-color-apply-on-region. Uses ansi-color-context-region such that repeated calls will strip partial escape sequences, too. (ansi-color-apply-on-region): Simplified code. Colorize end of region if face is not null. Store context in new (FACE POS) format, such that repeated calls will strip partial escape sequences, too. Append faces to face property using ansi-color-apply-sequence such that cumulative mode actually works. (ansi-color-apply-sequence): New function. (ansi-color-get-face): When the default face is added to the list of faces, all previous settings are discarded and the list of faces is set to '(default). (ansi-color-faces-vector): Use nil for the default face, such that ansi-color-apply and ansi-color-apply-on-region will do the right thing. (ansi-color-apply): Do the right thing, ie. if ansi-color-get-face returns nil, set the list of faces back to nil instead of appending the result of ansi-color-get-face to the front of the list. (ansi-color-for-comint-mode): Doc change. (ansi-color-process): Doc change. (ansi-color-last-context): New buffer-local variable. (ansi-color-process-output): New function. It is automatically added to comint-output-filter-functions if this is XEmacs. (ansi-color-unfontify-region): New optional parameter for XEmacs compatibility. Check wether font-lock-syntactic-keywords is boundp before removing the syntax table text property, as XEmacs doesn't have it. (ansi-color-filter-region): Doc change. (ansi-color-apply-on-region): Doc change. (ansi-color-make-face): New function. Compatibility layer for XEmacs. Return temporary faces instead of cons cells for XEmacs. (ansi-color-make-color-map): Use ansi-color-make-face. (ansi-color-get-face): Avoid face text property '(nil) as results in an errow for XEmacs. (ansi-color-unfontify-region): New function. Uses text-property ansi-color in order to preserve fontification by ansi-color. When the package is loaded, a lambda expression is put onto font-lock-mode-hook. This lambda expression will check font-lock-unfontify-region-function and replace font-lock-default-unfontify-region with ansi-color-unfontify-region. (ansi-color-apply): Add text-property ansi-color in addition to text-property face. (ansi-color-apply-on-region): Add text-property ansi-color in addition to text-property face. (save-buffer-state): Copy of the macro that is also used by lazy-lock and font-lock. (ansi-color-for-comint-mode): New option. (ansi-color-for-comint-mode-on): Set ansi-color-for-comint-mode. (ansi-color-for-comint-mode-off): Ditto. (ansi-color-for-comint-mode-filter): Ditto. (ansi-color-process): New function. Uses ansi-color-for-comint-mode to decide what to do. This function is added to comint-preoutput-filter-functions when the package is loaded. (ansi-color-for-shell-mode-set): Removed. (ansi-color-for-shell-mode): Removed. (ansi-color-for-shell-mode-set): New function with the lambda expression from the ansi-color-for-shell-mode :set property. Additionally, modify shell-mode-hook to enable or disable font-lock-mode for future shell buffers. (ansi-color-for-shell-mode): The :set property calls ansi-color-for-shell-mode-set instead of a lambda expression. (ansi-color-for-shell-mode): Doc change. (ansi-color-context): New variable. (ansi-color-apply): Save context between calls.

;; This allows you to run ls --color=yes in shell-mode. In order to
;; test this, proceed as follows:
;;
;; 1. start a shell: M-x shell
;; 2. load this file: M-x load-library RET ansi-color RET
;; 3. activate ansi-color: M-x ansi-color-for-comint-mode-on
;; 4. test ls --color=yes in the *shell* buffer
;;
;; Note that starting your shell from within Emacs might set the TERM
;; environment variable. The new setting might disable the output of
;; SGR control sequences. Using ls --color=yes forces ls to produce
;; these.
;;
;; If you decide you like this, add the following to your .emacs file:
;;
;; (autoload 'ansi-color-for-comint-mode-on "ansi-color" nil t)
;; (add-hook 'shell-mode-hook 'ansi-color-for-comint-mode-on)

;; "Graphic Rendition Combination Mode (GRCM)" implemented is
;; "cumulative mode" as defined in section 7.2.8. Cumulative mode means
;; that whenever possible, SGR control sequences are combined (ie. blue
;; and bold).

to insert the strings returned by `ansi-color-apply' into such buffers,
you must set `font-lock-unfontify-region-function' to

text-properties unconditionally. It will keep the face text-properties
if the property `ansi-color' is set.

are given in `ansi-color-faces-vector' and `ansi-color-names-vector'.
See function `ansi-color-apply-sequence' for details.
Every call to this function will set and use the buffer-local variable
`ansi-color-context' to save partial escape sequences and current face.
This information will be used for the next call to `ansi-color-apply'.
Set `ansi-color-context' to nil if you don't want this.
This function can be added to `comint-preoutput-filter-functions'.
You cannot insert the strings returned into buffers using font-lock.

(ansi-color-process-output): Use markers instead of positions for start and end of region. (ansi-color-apply-on-region): Rewrote code to make it more robust. Previously, occasional mistakes happend when fontifying many chunks of output (eg. ls --color=yes /dev). This happened whenever an overlay was created up to the end of the region, which coincided with the process-mark. New text would then be added within that overlay instead of after it. (ansi-color-make-extent): Overlays are created with the property `modification-hooks' set to '(ansi-color-freeze-overlay). (ansi-color-freeze-overlay): New function.
