search dependencies between go modules from the output of go mod graph
go install github.com/LeGEC/gosumwhy@latest
from within a go module (it internally runs go mod graph and reads the graph from the output of that command) :
gosumwhy list # list all modules present in the graph
gosumwhy path module/name@version # print a dependency path to that module@version
gosumwhy -allv path module/name # print a dependency path for each version of that module
See gosumwhy -h for more details on ways to provide a dependency graph:
# from stdin:
go mod graph | gosumwhy ...
# from a file (e.g: generated using 'go mod graph > graph.txt'):
gosumwhy -f graph.txt ...
# running 'go mod graph' in a module located somewhere else on disk:
gosumwhy -modpath path/to/module ...
