# Description: Run custom search and list results in smart context
|
||
|
|
#
|
||
|
|
# Note: This plugin retains search history
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# Run plugin and enter e.g. "-size +10M" to list files in current
|
||
|
|
# directory larger than 10M. By default entered expressions are
|
||
|
|
# interpreted as arguments to find. Results have to be NUL
|
||
|
|
# terminated which is done by default for find. Alternatively one
|
||
|
|
# can prepend a '$' to run a custom search program such as fd or
|
||
|
|
# ripgrep. Entered expressions will be saved in history file to
|
||
|
|
# be listed as bookmarks and and can be entered by index and edited.
