git module to go mod

Converts git submodules in a vendor directory to a go.mod file.

Running

Just running the program:

$ gitmod2gomod --repo-path ~/go/src/go.otter.engineering/gitmoddep

or direct the output to the source directory:

$ gitmod2gomod \
 --repo-path ~/go/src/go.otter.engineering/gitmoddep > \
 ~/go/src/go.otter.engineering/gitmoddep/go.mod

Generated File

$ cat go.mod
module go.otter.engineering/gitmoddep

require (

  go.uber.org/zap  67bc79d13d155c02fd008f721863ff8cc5f30659
