Resolución de conflictos con Emacs Ediff: ¿Cómo puedo tomar los cambios de ambas versiones?

emacs-ediff

Question

(Pregunta adaptada de ¿Cómo combino las dos variantes de un conflicto en emacs ''emerge? )

Tengo un archivo con marcadores de conflicto de fusión. Se ve similar a esto:

Uso Mx vc-resolve-conflicts para iniciar Ediff . Puedo seleccionar la variante A o B presionando aob en mi teclado, pero ¿cómo combino ambas variantes, una después de la otra?

Answer 1

Esto hace lo mismo que la respuesta útil de Trey Jackson, y es mucho más simple. Presionando d se copiarán A y B al buffer C.

(defun ediff-copy-both-to-C ()
  (interactive)
  (ediff-copy-diff ediff-current-difference nil ''C nil
                   (concat
                    (ediff-get-region-contents ediff-current-difference ''A ediff-control-buffer)
                    (ediff-get-region-contents ediff-current-difference ''B ediff-control-buffer))))
(defun add-d-to-ediff-mode-map () (define-key ediff-mode-map "d" ''ediff-copy-both-to-C))
(add-hook ''ediff-keymap-setup-hook ''add-d-to-ediff-mode-map)

Answer 2

La cadena de documentación para vc-resolve-conflicts dice que es un alias para smerge-ediff .

Si eso está funcionando como esperaba, entonces tu buffer debería estar en modo secundario de smerge, y debería haber un menú para smerge. Ese menú contiene todo lo que necesitas.

Answer 3

Puede cambiar al buffer "C" y editarlo. Presione + Si ya ha elegido A o B para restaurar la diferencia.

Si lo que buscas es presionar una tecla para eliminar automáticamente los marcadores de diferencias, solo puedo decir que parece una idea terrible.

Las fusiones manuales deben dejarse en manos del usuario. Eliminar pistas sobre de dónde viene cada región diff no me parece bien.

Puede personalizar los marcadores para que sean líneas en blanco con esto:

METRO-:

(setq ediff-combination-pattern ''("" A "" B "" Ancestor))

Answer 4

Sí, ¡totalmente quiero hacer esto! Con el siguiente fragmento de código, puede obtener ambos escribiendo d , que le proporcionará el código tanto del búfer A como del búfer B (en ese orden) en el búfer de fusión.

La única dificultad real en este código es el hecho de que ediff usa una macro en un lugar, y la versión compilada de la función necesita ser reevaluada con la nueva macro. De todos modos, prueba el código. Probado con Emacs 23.2.

(require ''ediff-init)           ;ensure the macro is defined, so we can override it

(defmacro ediff-char-to-buftype (arg)
  `(cond ((memq ,arg ''(?a ?A)) ''A)
     ((memq ,arg ''(?b ?B)) ''B)
     ((memq ,arg ''(?c ?C)) ''C)
     ((memq ,arg ''(?d ?D)) ''D)
     ))

(require ''ediff)

;; Literally copied from ediff-util
;; need to re-evaluate because it uses the macro defined above
;; and the compiled version needs to be re-compiled with the new definition
;; why a macro????
(defun ediff-diff-to-diff (arg &optional keys)
  "Copy buffer-X''th difference region to buffer Y /(X,Y are A, B, or C/).

Otherwise, copy the difference given by `ediff-current-difference''.
This command assumes it is bound to a 2-character key sequence, `ab'', `ba'',
`ac'', etc., which is used to determine the types of buffers to be used for
copying difference regions.  The first character in the sequence specifies
the source buffer and the second specifies the target.

If the second optional argument, a 2-character string, is given, use it to
determine the source and the target buffers instead of the command keys."
