# 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} [{conditionalmodule}]`
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 _{module} will be
replaced by a relative path to the in-repo
version of _{module}_.
If _conditionalModule_ is specified, then
the replacement of _{module}_ will happen
if _m_ depends on _{conditionalModule}_.
#### `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 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.
