The embark-consult package contains a new exporter for consult-location targets (produced by several consult commands such as consult-line), which exports to a grep mode buffer. Users wishing to use the new grep mode exporter can use the following configuration:
(setf (alist-get 'consult-location embark-exporters-alist)
#'embark-consult-export-location-grep)
The main reason for adding the new exporter is that users of the wgrep package will be able to make use of a feature that wgrep has and the built-in occur-edit-mode lacks: when editing search results you can add new lines to a result location. There are also some disadvantages of grep mode compared to occur mode (which is why the previously existing occur mode exporter continues to be the default): (1) wgrep is a third party package while occur-edit-mode is built-in; (2) occur mode buffers can list lines in any kind of buffer, but grep mode and wgrep are meant for lines of files exclusively.
