# Contributing
1. [File an issue](https://github.com/googleapis/google-cloud-go/issues/new/choose).
The issue will be used to discuss the bug or feature and should be created
before sending a CL.
1. [Install Go](https://golang.org/dl/).
1. Ensure that your `GOBIN` directory (by default `$(go env GOPATH)/bin`)
is in your `PATH`.
1. Check it's working by running `go version`.
* If it doesn't work, check the install location, usually
`/usr/local/go`, is on your `PATH`.
1. Sign one of the
[contributor license agreements](#contributor-license-agreements) below.
1. Run `go get golang.org/x/review/git-codereview && go install golang.org/x/review/git-codereview`
to install the code reviewing tool.
1. Ensure it's working by running `git codereview` (check your `PATH` if
not).
1. If you would like, you may want to set up aliases for `git-codereview`,
such that `git codereview change` becomes `git change`. See the
[godoc](https://pkg.go.dev/golang.org/x/review/git-codereview) for details.
* Should you run into issues with the `git-codereview` tool, please note
that all error messages will assume that you have set up these aliases.
1. Change to a directory of your choosing and clone the repo.
```
cd ~/code
git clone https://code.googlesource.com/gocloud
```
* If you have already checked out the source, make sure that the remote
`git` `origin` is https://code.googlesource.com/gocloud:
```
git remote -v
# ...
git remote set-url origin https://code.googlesource.com/gocloud
```
* The project uses [Go Modules](https://blog.golang.org/using-go-modules)
for dependency management See
[`gopls`](https://github.com/golang/go/wiki/gopls) for making your editor
work with modules.
1. Change to the project directory:
```
cd ~/code/gocloud
```
1. Make sure your `git` auth is configured correctly by visiting
https://code.googlesource.com, clicking "Generate Password" at the top-right,
and following the directions. Otherwise, `git codereview mail` in the next step
will fail.
1. Now you are ready to make changes. Don't create a new branch or make commits in the traditional
way. Use the following`git codereview` commands to create a commit and create a Gerrit CL:
```
git codereview change <branch-name> # Use this instead of git checkout -b <branch-name>
# Make changes.
git add ...
git codereview change # Use this instead of git commit
git codereview mail # If this fails, the error message will contain instructions to fix it.
```
* This will create a new `git` branch for you to develop on. Once your
change is merged, you can delete this branch.
1. As you make changes for code review, ammend the commit and re-mail the
change:
```
# Make more changes.
git add ...
git codereview change
git codereview mail
```
* **Warning**: do not change the `Change-Id` at the bottom of the commit
message - it's how Gerrit knows which change this is (or if it's new).
* When you fixes issues from code review, respond to each code review
message then click **Reply** at the top of the page.
* Each new mailed amendment will create a new patch set for
your change in Gerrit. Patch sets can be compared and reviewed.
* **Note**: if your change includes a breaking change, our breaking change
detector will cause CI/CD to fail. If your breaking change is acceptable
in some way, add a `BREAKING_CHANGE_ACCEPTABLE=<reason>` line to the commit
message to cause the detector not to be run and to make it clear why that is
acceptable.
1. Finally, add reviewers to your CL when it's ready for review. Reviewers will
not be added automatically. If you're not sure who to add for your code review,
add tbp@, cbro@, and codyoss@.
## Integration Tests
In addition to the unit tests, you may run the integration test suite. These
directions describe setting up your environment to run integration tests for
_all_ packages: note that many of these instructions may be redundant if you
intend only to run integration tests on a single package.
#### GCP Setup
To run the integrations tests, creation and configuration of two projects in
the Google Developers Console is required: one specifically for Firestore
integration tests, and another for all other integration tests. We'll refer to
these projects as "general project" and "Firestore project".
After creating each project, you must [create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount)
for each project. Ensure the project-level **Owner**
[IAM role](console.cloud.google.com/iam-admin/iam/project) role is added to
each service account. During the creation of the service account, you should
download the JSON credential file for use later.
Next, ensure the following APIs are enabled in the general project:
- BigQuery API
- BigQuery Data Transfer API
- Cloud Dataproc API
- Cloud Dataproc Control API Private
- Cloud Datastore API
- Cloud Firestore API
- Cloud Key Management Service (KMS) API
- Cloud Natural Language API
- Cloud OS Login API
- Cloud Pub/Sub API
- Cloud Resource Manager API
- Cloud Spanner API
- Cloud Speech API
- Cloud Translation API
- Cloud Video Intelligence API
- Cloud Vision API
- Compute Engine API
- Compute Engine Instance Group Manager API
- Container Registry API
- Firebase Rules API
- Google Cloud APIs
- Google Cloud Deployment Manager V2 API
- Google Cloud SQL
- Google Cloud Storage
- Google Cloud Storage JSON API
- Google Compute Engine Instance Group Updater API
- Google Compute Engine Instance Groups API
- Kubernetes Engine API
- Stackdriver Error Reporting API
Next, create a Datastore database in the general project, and a Firestore
database in the Firestore project.
Finally, in the general project, create an API key for the translate API:
- Go to GCP Developer Console.
- Navigate to APIs & Services > Credentials.
- Click Create Credentials > API Key.
- Save this key for use in `GCLOUD_TESTS_API_KEY` as described below.
#### Local Setup
Once the two projects are created and configured, set the following environment
variables:
- `GCLOUD_TESTS_GOLANG_PROJECT_ID`: Developers Console project's ID (e.g.
bamboo-shift-455) for the general project.
- `GCLOUD_TESTS_GOLANG_KEY`: The path to the JSON key file of the general
project's service account.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID`: Developers Console project's ID
(e.g. doorway-cliff-677) for the Firestore project.
- `GCLOUD_TESTS_GOLANG_FIRESTORE_KEY`: The path to the JSON key file of the
Firestore project's service account.
- `GCLOUD_TESTS_GOLANG_KEYRING`: The full name of the keyring for the tests,
in the form
"projects/P/locations/L/keyRings/R". The creation of this is described below.
- `GCLOUD_TESTS_API_KEY`: API key for using the Translate API.
- `GCLOUD_TESTS_GOLANG_ZONE`: Compute Engine zone.
Install the [gcloud command-line tool][gcloudcli] to your machine and use it to
create some resources used in integration tests.
From the project's root directory:
``` sh
# Sets the default project in your env.
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
# Authenticates the gcloud tool with your account.
$ gcloud auth login
# Create the indexes used in the datastore integration tests.
$ gcloud datastore indexes create datastore/testdata/index.yaml
# Creates a Google Cloud storage bucket with the same name as your test project,
# and with the Stackdriver Logging service account as owner, for the sink
# integration tests in logging.
$ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
$ gsutil acl ch -g cloud-logs@google.com:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
# Creates a PubSub topic for integration tests of storage notifications.
$ gcloud beta pubsub topics create go-storage-notification-test
# Next, go to the Pub/Sub dashboard in GCP console. Authorize the user
# "service-<numberic project id>@gs-project-accounts.iam.gserviceaccount.com"
# as a publisher to that topic.
# Creates a Spanner instance for the spanner integration tests.
$ gcloud beta spanner instances create go-integration-test --config regional-us-central1 --nodes 10 --description 'Instance for go client test'
# NOTE: Spanner instances are priced by the node-hour, so you may want to
# delete the instance after testing with 'gcloud beta spanner instances delete'.
$ export MY_KEYRING=some-keyring-name
$ export MY_LOCATION=global
# Creates a KMS keyring, in the same location as the default location for your
# project's buckets.
$ gcloud kms keyrings create $MY_KEYRING --location $MY_LOCATION
# Creates two keys in the keyring, named key1 and key2.
$ gcloud kms keys create key1 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
$ gcloud kms keys create key2 --keyring $MY_KEYRING --location $MY_LOCATION --purpose encryption
# Sets the GCLOUD_TESTS_GOLANG_KEYRING environment variable.
$ export GCLOUD_TESTS_GOLANG_KEYRING=projects/$GCLOUD_TESTS_GOLANG_PROJECT_ID/locations/$MY_LOCATION/keyRings/$MY_KEYRING
# Authorizes Google Cloud Storage to encrypt and decrypt using key1.
gsutil kms authorize -p $GCLOUD_TESTS_GOLANG_PROJECT_ID -k $GCLOUD_TESTS_GOLANG_KEYRING/cryptoKeys/key1
```
#### Running
Once you've done the necessary setup, you can run the integration tests by
running:
``` sh
$ go test -v cloud.google.com/go/...
```
#### Replay
Some packages can record the RPCs during integration tests to a file for
subsequent replay. To record, pass the `-record` flag to `go test`. The
recording will be saved to the _package_`.replay` file. To replay integration
tests from a saved recording, the replay file must be present, the `-short`
flag must be passed to `go test`, and the `GCLOUD_TESTS_GOLANG_ENABLE_REPLAY`
environment variable must have a non-empty value.

# Google Cloud Client Libraries for Go
[![GoDoc](https://pkg.go.dev/cloud.google.com/go?status.svg)](https://pkg.go.dev/cloud.google.com/go)
Go packages for [Google Cloud Platform](https://cloud.google.com) services.
``` go
import "cloud.google.com/go"
```
To install the packages on your system, *do not clone the repo*. Instead:
1. Change to your project directory:
```
cd /my/cloud/project
```
1. Get the package you want to use. Some products have their own module, so it's
best to `go get` the package(s) you want to use:
```
$ go get cloud.google.com/go/firestore # Replace with the package you want to use.
```
**NOTE:** Some of these packages are under development, and may occasionally
make backwards-incompatible changes.
**NOTE:** Github repo is a mirror of [https://code.googlesource.com/gocloud](https://code.googlesource.com/gocloud).

Documentation and examples are available at [pkg.go.dev/cloud.google.com/go](https://pkg.go.dev/cloud.google.com/go)
## Go Versions Supported
We support the two most recent major versions of Go. If Google App Engine uses
an older version, we support that as well.
## Authorization
By default, each API will use [Google Application Default Credentials](https://developers.google.com/identity/protocols/application-default-credentials)
for authorization credentials used in calling the API endpoints. This will allow your
application to run in many environments without requiring explicit configuration.
[snip]:# (auth)
```go
client, err := storage.NewClient(ctx)
```
To authorize using a
[JSON key file](https://cloud.google.com/iam/docs/managing-service-account-keys),
pass
[`option.WithCredentialsFile`](https://pkg.go.dev/google.golang.org/api/option#WithCredentialsFile)
to the `NewClient` function of the desired package. For example:
[snip]:# (auth-JSON)
```go
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
```
You can exert more control over authorization by using the
[`golang.org/x/oauth2`](https://pkg.go.dev/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://pkg.go.dev/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```

# Setup from scratch
1. [Install Go](https://golang.org/dl/).
1. Ensure that your `GOBIN` directory (by default `$(go env GOPATH)/bin`)
is in your `PATH`.
1. Check it's working by running `go version`.
* If it doesn't work, check the install location, usually
`/usr/local/go`, is on your `PATH`.
1. Sign one of the
[contributor license agreements](#contributor-license-agreements) below.
1. Run `go get golang.org/x/review/git-codereview && go install golang.org/x/review/git-codereview`
to install the code reviewing tool.
1. Ensure it's working by running `git codereview` (check your `PATH` if
not).
1. If you would like, you may want to set up aliases for `git-codereview`,
such that `git codereview change` becomes `git change`. See the
[godoc](https://pkg.go.dev/golang.org/x/review/git-codereview) for details.
* Should you run into issues with the `git-codereview` tool, please note
that all error messages will assume that you have set up these aliases.
1. Change to a directory of your choosing and clone the repo.
```
cd ~/code
git clone https://code.googlesource.com/gocloud
```
* If you have already checked out the source, make sure that the remote
`git` `origin` is https://code.googlesource.com/gocloud:
```
git remote -v
# ...
git remote set-url origin https://code.googlesource.com/gocloud
```
* The project uses [Go Modules](https://blog.golang.org/using-go-modules)
for dependency management See
[`gopls`](https://github.com/golang/go/wiki/gopls) for making your editor
work with modules.
1. Change to the project directory and add the github remote:
```
cd ~/code/gocloud
git remote add github https://github.com/googleapis/google-cloud-go
```
1. Make sure your `git` auth is configured correctly by visiting
https://code.googlesource.com, clicking "Generate Password" at the top-right,
and following the directions. Otherwise, `git codereview mail` in the next step
will fail.
# Which module to release?
The Go client libraries have several modules. Each module does not strictly
correspond to a single library - they correspond to trees of directories. If a
file needs to be released, you must release the closest ancestor module.
To see all modules:
```
$ cat `find . -name go.mod` | grep module
module cloud.google.com/go
module cloud.google.com/go/bigtable
module cloud.google.com/go/firestore
module cloud.google.com/go/bigquery
module cloud.google.com/go/storage
module cloud.google.com/go/datastore
module cloud.google.com/go/pubsub
module cloud.google.com/go/spanner
module cloud.google.com/go/logging
```
The `cloud.google.com/go` is the repository root module. Each other module is
a submodule.
So, if you need to release a change in `bigtable/bttest/inmem.go`, the closest
ancestor module is `cloud.google.com/go/bigtable` - so you should release a new
version of the `cloud.google.com/go/bigtable` submodule.
If you need to release a change in `asset/apiv1/asset_client.go`, the closest
ancestor module is `cloud.google.com/go` - so you should release a new version
of the `cloud.google.com/go` repository root module. Note: releasing
`cloud.google.com/go` has no impact on any of the submodules, and vice-versa.
They are released entirely independently.
# How to release `cloud.google.com/go`
1. Navigate to `~/code/gocloud/` and switch to master.
1. `git pull`
1. Run `git tag -l | grep -v beta | grep -v alpha` to see all existing releases.
The current latest tag `$CV` is the largest tag. It should look something
like `vX.Y.Z` (note: ignore all `LIB/vX.Y.Z` tags - these are tags for a
specific library, not the module root). We'll call the current version `$CV`
and the new version `$NV`.
1. On master, run `git log $CV...` to list all the changes since the last
release. NOTE: You must manually visually parse out changes to submodules [1]
(the `git log` is going to show you things in submodules, which are not going
to be part of your release).
1. Edit `CHANGES.md` to include a summary of the changes.
1. `cd internal/version && go generate && cd -`
1. Mail the CL: `git add -A && git change <branch name> && git mail`
1. Wait for the CL to be submitted. Once it's submitted, and without submitting
any other CLs in the meantime:
a. Switch to master.
b. `git pull`
c. Tag the repo with the next version: `git tag $NV`.
d. Push the tag to both remotes:
`git push origin $NV`
`git push github $NV`
1. Update [the releases page](https://github.com/googleapis/google-cloud-go/releases)
with the new release, copying the contents of `CHANGES.md`.
# How to release a submodule
We have several submodules, including `cloud.google.com/go/logging`,
`cloud.google.com/go/datastore`, and so on.
To release a submodule:
(these instructions assume we're releasing `cloud.google.com/go/datastore` - adjust accordingly)
1. Navigate to `~/code/gocloud/` and switch to master.
1. `git pull`
1. Run `git tag -l | grep datastore | grep -v beta | grep -v alpha` to see all
existing releases. The current latest tag `$CV` is the largest tag. It
should look something like `datastore/vX.Y.Z`. We'll call the current version
`$CV` and the new version `$NV`.
1. On master, run `git log $CV.. -- datastore/` to list all the changes to the
submodule directory since the last release.
1. Edit `datastore/CHANGES.md` to include a summary of the changes.
1. `cd internal/version && go generate && cd -`
1. Mail the CL: `git add -A && git change <branch name> && git mail`
1. Wait for the CL to be submitted. Once it's submitted, and without submitting
any other CLs in the meantime:
a. Switch to master.
b. `git pull`
c. Tag the repo with the next version: `git tag $NV`.
d. Push the tag to both remotes:
`git push origin $NV`
`git push github $NV`
1. Update [the releases page](https://github.com/googleapis/google-cloud-go/releases)
with the new release, copying the contents of `datastore/CHANGES.md`.
# Appendix
1: This should get better as submodule tooling matures.

Package cloud is the root of the packages used to access Google Cloud
Services. See https://godoc.org/cloud.google.com/go for a full list
of sub-packages.
Client Options
All clients in sub-packages are configurable via client options. These options are
described here: https://godoc.org/google.golang.org/api/option.
Authentication and Authorization
All the clients in sub-packages support authentication via Google Application Default
Credentials (see https://cloud.google.com/docs/authentication/production), or
by providing a JSON key file for a Service Account. See the authentication examples
in this package for details.
Timeouts and Cancellation
By default, all requests in sub-packages will run indefinitely, retrying on transient
errors when correctness allows. To set timeouts or arrange for cancellation, use
contexts. See the examples for details.
Do not attempt to control the initial connection (dialing) of a service by setting a
timeout on the context passed to NewClient. Dialing is non-blocking, so timeouts
would be ineffective and would only interfere with credential refreshing, which uses
the same context.
Connection Pooling
Connection pooling differs in clients based on their transport. Cloud
clients either rely on HTTP or gRPC transports to communicate
with Google Cloud.
Cloud clients that use HTTP (bigquery, compute, storage, and translate) rely on the
underlying HTTP transport to cache connections for later re-use. These are cached to
the default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in
http.DefaultTransport.
For gRPC clients (all others in this repo), connection pooling is configurable. Users
of cloud client libraries may specify option.WithGRPCConnectionPool(n) as a client
option to NewClient calls. This configures the underlying gRPC connections to be
pooled and addressed in a round robin fashion.
Using the Libraries with Docker
Minimal docker images like Alpine lack CA certificates. This causes RPCs to appear to
hang, because gRPC retries indefinitely. See https://github.com/googleapis/google-cloud-go/issues/928
for more information.
Debugging
To see gRPC logs, set the environment variable GRPC_GO_LOG_SEVERITY_LEVEL. See
https://godoc.org/google.golang.org/grpc/grpclog for more information.
For HTTP logging, set the GODEBUG environment variable to "http2debug=1" or "http2debug=2".
Client Stability
Clients in this repository are considered alpha or beta unless otherwise
marked as stable in the README.md. Semver is not used to communicate stability
of clients.
Alpha and beta clients may change or go away without notice.
Clients marked stable will maintain compatibility with future versions for as
long as we can reasonably sustain. Incompatible changes might be made in some
situations, including:
- Security bugs may prompt backwards-incompatible changes.
- Situations in which components are no longer feasible to maintain without
making breaking changes, including removal.
- Parts of the client surface may be outright unstable and subject to change.
These parts of the surface will be labeled with the note, "It is EXPERIMENTAL
and subject to change or removal without notice."

# Internal
This directory contains internal code for cloud.google.com/go packages.
## .repo-metadata-full.json
`.repo-metadata-full.json` contains metadata about the packages in this repo. It
is generated by `internal/gapicgen/generator`. It's processed by external tools
to build lists of all of the packages.
Don't make breaking changes to the format without consulting with the external
tools.
One day, we may want to create individual `.repo-metadata.json` files next to
each package, which is the pattern followed by some other languages. External
tools would then talk to pkg.go.dev or some other service to get the overall
list of packages and use the `.repo-metadata.json` files to get the additional
metadata required. For now, `.repo-metadata-full.json` includes everything.

# Changes
## v1.8.0
- Add support for V4 signed post policies.
## v1.7.0
- V4 signed URL support:
- Add support for bucket-bound domains and virtual hosted style URLs.
- Add support for query parameters in the signature.
- Fix text encoding to align with standards.
- Add the object name to query parameters for write calls.
- Fix retry behavior when reading files with Content-Encoding gzip.
- Fix response header in reader.
- New code examples:
- Error handling for `ObjectHandle` preconditions.
- Existence checks for buckets and objects.
## v1.6.0
- Updated option handling:
- Don't drop custom scopes (#1756)
- Don't drop port in provided endpoint (#1737)
## v1.5.0
- Honor WithEndpoint client option for reads as well as writes.
- Add archive storage class to docs.
- Make fixes to storage benchwrapper.
## v1.4.0
- When listing objects in a bucket, allow callers to specify which attributes
are queried. This allows for performance optimization.
## v1.3.0
- Use `storage.googleapis.com/storage/v1` by default for GCS requests
instead of `www.googleapis.com/storage/v1`.
## v1.2.1
- Fixed a bug where UniformBucketLevelAccess and BucketPolicyOnly were not
being sent in all cases.
## v1.2.0
- Add support for UniformBucketLevelAccess. This configures access checks
to use only bucket-level IAM policies.
See: https://godoc.org/cloud.google.com/go/storage#UniformBucketLevelAccess.
- Fix userAgent to use correct version.
## v1.1.2
- Fix memory leak in BucketIterator and ObjectIterator.
## v1.1.1
- Send BucketPolicyOnly even when it's disabled.
## v1.1.0
- Performance improvements for ObjectIterator and BucketIterator.
- Fix Bucket.ObjectIterator size calculation checks.
- Added HMACKeyOptions to all the methods which allows for options such as
UserProject to be set per invocation and optionally be used.
## v1.0.0
This is the first tag to carve out storage as its own module. See:
https://github.com/golang/go/wiki/Modules#is-it-possible-to-add-a-module-to-a-multi-module-repository.

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

### Example Usage
First create a `storage.Client` to use throughout your application:
[snip]:# (storage-1)
```go
client, err := storage.NewClient(ctx)
if err != nil {
log.Fatal(err)
}
```
[snip]:# (storage-2)
```go
// Read the object1 from bucket.
rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
if err != nil {
log.Fatal(err)
}
defer rc.Close()
body, err := ioutil.ReadAll(rc)
if err != nil {
log.Fatal(err)
}
```

## TOML parser and encoder for Go with reflection
TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
reflection interface similar to Go's standard library `json` and `xml`
packages. This package also supports the `encoding.TextUnmarshaler` and
`encoding.TextMarshaler` interfaces so that you can define custom data
representations. (There is an example of this below.)
Spec: https://github.com/toml-lang/toml
Compatible with TOML version
[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
Documentation: https://godoc.org/github.com/BurntSushi/toml
Installation:
```bash
go get github.com/BurntSushi/toml
```
Try the toml validator:
```bash
go get github.com/BurntSushi/toml/cmd/tomlv
tomlv some-toml-file.toml
```
[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
### Testing
This package passes all tests in
[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
and the encoder.
### Examples
This package works similarly to how the Go standard library handles `XML`
and `JSON`. Namely, data is loaded into Go values via reflection.
For the simplest example, consider some TOML file as just a list of keys
and values:
```toml
Age = 25
Cats = [ "Cauchy", "Plato" ]
Pi = 3.14
Perfection = [ 6, 28, 496, 8128 ]
DOB = 1987-07-05T05:45:00Z
```
Which could be defined in Go as:
```go
type Config struct {
Age int
Cats []string
Pi float64
Perfection []int
DOB time.Time // requires `import time`
}
```
And then decoded with:
```go
var conf Config
if _, err := toml.Decode(tomlData, &conf); err != nil {
// handle error
}
```
You can also use struct tags if your struct field name doesn't map to a TOML
key value directly:
```toml
some_key_NAME = "wat"
```
```go
type TOML struct {
ObscureKey string `toml:"some_key_NAME"`
}
```
### Using the `encoding.TextUnmarshaler` interface
Here's an example that automatically parses duration strings into
`time.Duration` values:
```toml
[[song]]
name = "Thunder Road"
duration = "4m49s"
[[song]]
name = "Stairway to Heaven"
duration = "8m03s"
```
Which can be decoded with:
```go
type song struct {
Name string
Duration duration
}
type songs struct {
Song []song
}
var favorites songs
if _, err := toml.Decode(blob, &favorites); err != nil {
log.Fatal(err)
}
for _, s := range favorites.Song {
fmt.Printf("%s (%s)\n", s.Name, s.Duration)
}
```
And you'll also need a `duration` type that satisfies the
`encoding.TextUnmarshaler` interface:
```go
type duration struct {
time.Duration
}
func (d *duration) UnmarshalText(text []byte) error {
var err error
d.Duration, err = time.ParseDuration(string(text))
return err
}
```
### More complex usage
Here's an example of how to load the example from the official spec page:
```toml
# This is a TOML document. Boom.
title = "TOML Example"
[owner]
name = "Tom Preston-Werner"
organization = "GitHub"
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
dob = 1979-05-27T07:32:00Z # First class dates? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
# You can indent as you please. Tabs or spaces. TOML don't care.
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
# Line breaks are OK when inside arrays
hosts = [
"alpha",
"omega"
]
```
And the corresponding Go types are:
```go
type tomlConfig struct {
Title string
Owner ownerInfo
DB database `toml:"database"`
Servers map[string]server
Clients clients
}
type ownerInfo struct {
Name string
Org string `toml:"organization"`
Bio string
DOB time.Time
}
type database struct {
Server string
Ports []int
ConnMax int `toml:"connection_max"`
Enabled bool
}
type server struct {
IP string
DC string
}
type clients struct {
Data [][]interface{}
Hosts []string
}
```
Note that a case insensitive match will be tried if an exact match can't be
found.
A working example of the above can be found in `_examples/example.{go,toml}`.

// Unmarshaler example for a demonstration with time duration strings.
//
// Key mapping
//
// TOML keys can map to either keys in a Go map or field names in a Go

// A case insensitive match to struct names will be tried if an exact match

// there may be parts of your representation that do not correspond to
// TOML values. This loose mapping can be made stricter by using the IsDefined
// and/or Undecoded methods on the MetaData returned.

/*
Package toml provides facilities for decoding and encoding TOML configuration
files via reflection. There is also support for delaying decoding with
the Primitive type, and querying the set of keys in a TOML document with the
MetaData type.
The specification implemented: https://github.com/toml-lang/toml
The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
whether a file is a valid TOML document. It can also be used to print the
type of each key in a TOML document.
Testing
There are two important types of tests used for this package. The first is
contained inside '*_test.go' files and uses the standard Go unit testing
framework. These tests are primarily devoted to holistically testing the
decoder and encoder.
The second type of testing is used to verify the implementation's adherence
to the TOML specification. These tests have been factored into their own
project: https://github.com/BurntSushi/toml-test
The reason the tests are in a separate project is so that they can be used by
any implementation of TOML. Namely, it is language agnostic.
