+# gorepomod
+
+Helps when you have a git repository with multiple Go modules.
+
+It handles tasks one might otherwise attempt with
+
+```
+find ./ -name "go.mod" | xargs {some hack}
+```
+
+Run it from a git repository root.
+
+It walks the repository, reads `go.mod` files, builds
+a model of Go modules and intra-repo module
+dependencies, then performs some operation.
+
+Install:
+```
+go get sigs.k8s.io/kustomize/cmd/gorepomod
+```
+
+## Usage
+
+_Commands that change things (everything but `list`)
+do nothing but log commands
+unless you add the `--doIt` flag,
+allowing the change._
+
+#### `gorepomod list`
+
+Lists modules and intra-repo dependencies.
+
+Use this to get module names for use in other commands.
+
+#### `gorepomod tidy`
+
+Creates a change with mechanical updates
+to `go.mod` and `go.sum` files.
+
+#### `gorepomod unpin {module}`
+
+Creates a change to `go.mod` files.
+
+For each module _m_ in the repository,
+if _m_ depends on a _{module}_,
+then _m_'s dependency on it will be replaced by
+a relative path to the in-repo module.
+
+#### `gorepomod pin {module} [{version}]`
+
+Creates a change to `go.mod` files.
+
+The opposite of `unpin`.
+  
+The change removes replacements and pins _m_ to a
+specific, previously tagged and released version of _{module}_.
+
+The argument _{version}_ defaults to recent version of _{module}_.
+
+_{version}_ should be in semver form, e.g. `v1.2.3`.
+
+
+#### `gorepomod release {module} [patch|minor|major]`
+
+Computes a new version for the module, tags the repo
+with that version, and pushes the tag to the remote.
+
+The value of the 2nd argument, either `patch` (the default),
+`minor` or `major`, determines the new version.
+
+If the existing version is _v1.2.7_, then the new version will be:
+ - `patch` -> _v1.2.8_
+ - `minor` -> _v1.3.0_
+ - `major` -> _v2.0.0_
+
+After establishing the the version, the command looks for a branch named
+
+> _release-{module}/-v{major}.{minor}_
+
+If the branch doesn't exist, the command creates it and pushes it to the remote.
+
+The command then creates a new tag in the form
+
+> _{module}/v{major}.{minor}.{patch}_
+
+The command pushes this tag to the remote.  This typically triggers
+cloud activity to create release artifacts.
+
+#### `gorepomod unrelease {module}`
+
+This undoes the work of `release`, by deleting the
+most recent tag both locally and at the remote.
+
+You can then fix whatever, and re-release.
+
+This, however, must be done almost immediately.
+
+If there's a chance someone (or some cloud robot) already
+imported the module at the given tag, then don't do this,
+because it will confuse module caches.
+
+Do a new patch release instead.
