What functionality exists to automate replacing text from a GNU Emacs *grep*
(results) buffer? What I mean, why I ask:
Suppose I want to change an identifier in some code. I `M-x find-grep` from the
root of the filetree of the sources and their docs, producing results like
buffer=*grep*
> find ../ -type f -print | grep -ve '[#~]$\|\.git/' | sort | xargs -e fgrep
> -nH -e 'F5NAP_FIREFOX_BUILD_DIR'
> ../scripts/install_Firefox_for_F5NAP.sh:88:elif [[ -z
> "${F5NAP_FIREFOX_BUILD_DIR}" ]] ; then
> ../scripts/install_Firefox_for_F5NAP.sh:89: echo -e "${ERROR_PREFIX}
> F5NAP_FIREFOX_BUILD_DIR not defined, exiting ..."
> ../scripts/install_Firefox_for_F5NAP.sh:119: "mkdir -p
> ${F5NAP_FIREFOX_BUILD_DIR}" \
> ../scripts/install_Firefox_for_F5NAP.sh:124: "find
> ${F5NAP_FIREFOX_BUILD_DIR} | wc -l" \
> ../scripts/public.properties:106:F5NAP_FIREFOX_BUILD_DIR="/tmp/${F5NAP_FIREFOX_WITH_VERSION}"
> ../scripts/public.properties:107:F5NAP_FIREFOX_UNZIP_DIR="${F5NAP_FIREFOX_BUILD_DIR}/firefox"
> ../scripts/start_Firefox_for_F5NAP.sh:82:elif [[ -z
> "${F5NAP_FIREFOX_BUILD_DIR}" ]] ; then
> ../scripts/start_Firefox_for_F5NAP.sh:83: echo -e "${ERROR_PREFIX}
> F5NAP_FIREFOX_BUILD_DIR not defined, exiting ..."
> ../scripts/start_Firefox_for_F5NAP.sh:113: "mkdir -p
> ${F5NAP_FIREFOX_BUILD_DIR}" \
> ../scripts/start_Firefox_for_F5NAP.sh:118: "find ${F5NAP_FIREFOX_BUILD_DIR}
> | wc -l" \
Depending on the results, I typically take 1 of 3 options:
0. |results| are large && results look dangerous: abort
1. |results| are large && results look safe: run `sed` from the root of the
filetree
2. |results| are small && results look safe: make a macro changing the first
one, then repeat on the rest.
Obviously there's no better solution for case#=0 :-) but my handling of the
other cases feels kludgey. Is there a {better, easier, more Emacs-y} way to
handle this?
OTTOMH, what I'd really like would be something that would "raise the level of
abstraction" (RLA) on a *grep* buffer in the manner that Wdired RLAs a Dired
buffer, by allowing one to treat file metadata as "mere text." If I'm in a
Dired buffer and want to make several changes to the names/permissions of a
bunch of files/subdirs of a single directory/folder, I
1. key 'w' to enter Wdired mode
2. apply any of the many wonderful means we have to do text editing on the
now-editable data
3. key 'C-c C-c'
Wdired then applies the changes made from the Dired buffer to the objects it
represents. So what I'd most like for my usecase would be to RLA on a *grep*
buffer, allowing a Wdired-like workflow.
Is there something like that for *grep* buffers, or something even better?
Apologies if this is a FAQ, but a (probably too casual) web search failed to
find.
