Usage

At first

create lock file

dub build -c makedeps
dub build -c diff-update

Basic

1. Modify source
2. Update diff
   • dub build -c diff
3. Do review with the dependency graph diff
   • Open the deps.svg in browser

Compare 2 versions

1. checkout a target version
   • git reset --hard XXX or git checkout XXXXX
2. reset to source version
   • git reset --hard HEAD~10 (e.g. 10 versions ago)
3. create deps-lock.txt
   • dub build -c makedeps
   • dub build -c diff-update
   • if dub.json / dub.sdl has not configure then add these.
     
4. reset to target version
   • git reset --hard ORIG_HEAD
5. make diff
   • dub build -c diff
6. open deps.svg
