Updating Go import statements using Comby
This batch change rewrites Go import paths for the
log15 package from
github.com/inconshreveable/log15 using Comby.
It can handle single-package import statements like this one:
Single-package imports with an alias:
import log15 "gopkg.in/inconshreveable/log15.v2"
And multi-package import statements with our without an alias:
import ( "io" "github.com/pkg/errors" "gopkg.in/inconshreveable/log15.v2" )
We recommend that use the latest version of Sourcegraph when working with Batch Changes and that you have a basic understanding of how to create batch specs and run them. See the following documents for more information:
Create the batch spec
Save the following batch spec YAML as

Create the batch change
In your terminal, run this command:
src batch preview -f update-log15-import.batch.yaml
Wait for it to run and compute the changes for each repository.
Open the preview URL that the command printed out.
Examine the preview. Confirm that the changesets are the ones you intended to track. If not, edit the batch spec and then rerun the command above.
Click the Apply spec button to create the batch change.
Feel free to then publish the changesets (i.e. create pull requests and merge requests) by modifying the
publishedattribute in the batch spec and re-running the
src batch previewcommand.
