reimport

Golang Import Patching tool

description

reimport is a quick & dirty tool for generating a patch(1) for import lines you want to change in large Go projects

it uses go/parser in order to accurately find the import lines (hence not patching code lines with matching string).

build / install

go get github.com/unix4fun/reimport

example usage

reimport -m hash -r myhash /path/to/dir > import.patch

example output:

$ reimport -m crypto -r tagada ~/dev/ic/
