(a) that the initial Contributor has attached the notice described in Exhibit
B to the Covered Software; or
(b) that the Covered Software was made available under the terms of version
1.1 or earlier of the License, but not also under the terms of a Secondary
License.
1.6. "Executable Form" means any form of the work other than Source Code Form.

2. License Grants and Conditions
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive
license:
(a) under intellectual property rights (other than patent or trademark) Licensable
by such Contributor to use, reproduce, make available, modify, display, perform,
distribute, and otherwise exploit its Contributions, either on an unmodified
basis, with Modifications, or as part of a Larger Work; and
(b) under Patent Claims of such Contributor to make, use, sell, offer for
sale, have made, import, and otherwise transfer either its Contributions or
its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution become
effective for each Contribution on the date the Contributor first distributes
such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under this
License. No additional rights or licenses will be implied from the distribution
or licensing of Covered Software under this License. Notwithstanding Section
2.1(b) above, no patent license is granted by a Contributor:
(a) for any code that a Contributor has removed from Covered Software; or
(b) for infringements caused by: (i) Your and any other third party's modifications
of Covered Software, or (ii) the combination of its Contributions with other
software (except as part of its Contributor Version); or
(c) under Patent Claims infringed by Covered Software in the absence of its
Contributions.
This License does not grant any rights in the trademarks, service marks, or
logos of any Contributor (except as may be necessary to comply with the notice
requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to distribute
the Covered Software under a subsequent version of this License (see Section
10.2) or under the terms of a Secondary License (if permitted under the terms
of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its Contributions
are its original creation(s) or it has sufficient rights to grant the rights
to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under applicable
copyright doctrines of fair use, fair dealing, or other equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
3. Responsibilities
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any Modifications
that You create or to which You contribute, must be under the terms of this
License. You must inform recipients that the Source Code Form of the Covered
Software is governed by the terms of this License, and how they can obtain
a copy of this License. You may not attempt to alter or restrict the recipients'
rights in the Source Code Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code Form,
as described in Section 3.1, and You must inform recipients of the Executable
Form how they can obtain a copy of such Source Code Form by reasonable means
in a timely manner, at a charge no more than the cost of distribution to the
recipient; and
(b) You may distribute such Executable Form under the terms of this License,
or sublicense it under different terms, provided that the license for the
Executable Form does not attempt to limit or alter the recipients' rights
in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice, provided
that You also comply with the requirements of this License for the Covered
Software. If the Larger Work is a combination of Covered Software with a work
governed by one or more Secondary Licenses, and the Covered Software is not
Incompatible With Secondary Licenses, this License permits You to additionally
distribute such Covered Software under the terms of such Secondary License(s),
so that the recipient of the Larger Work may, at their option, further distribute
the Covered Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices (including
copyright notices, patent notices, disclaimers of warranty, or limitations
of liability) contained within the Source Code Form of the Covered Software,
except that You may alter any license notices to the extent required to remedy
known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support, indemnity
or liability obligations to one or more recipients of Covered Software. However,
You may do so only on Your own behalf, and not on behalf of any Contributor.
You must make it absolutely clear that any such warranty, support, indemnity,
or liability obligation is offered by You alone, and You hereby agree to indemnify
every Contributor for any liability incurred by such Contributor as a result
of warranty, support, indemnity or liability terms You offer. You may include
additional disclaimers of warranty and limitations of liability specific to
any jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute, judicial
order, or regulation then You must: (a) comply with the terms of this License
to the maximum extent possible; and (b) describe the limitations and the code
they affect. Such description must be placed in a text file included with
all distributions of the Covered Software under this License. Except to the
extent prohibited by statute or regulation, such description must be sufficiently
detailed for a recipient of ordinary skill to be able to understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically if
You fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor are
reinstated (a) provisionally, unless and until such Contributor explicitly
and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor
fails to notify You of the non-compliance by some reasonable means prior to
60 days after You have come back into compliance. Moreover, Your grants from
a particular Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the first
time You have received notice of non-compliance with this License from such
Contributor, and You become compliant prior to 30 days after Your receipt
of the notice.
5.2. If You initiate litigation against any entity by asserting a patent infringement
claim (excluding declaratory judgment actions, counter-claims, and cross-claims)
alleging that a Contributor Version directly or indirectly infringes any patent,
then the rights granted to You by any and all Contributors for the Covered
Software under Section 2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end
user license agreements (excluding distributors and resellers) which have
been validly granted by You or Your distributors under this License prior
to termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an "as is" basis, without
warranty of any kind, either expressed, implied, or statutory, including,
without limitation, warranties that the Covered Software is free of defects,
merchantable, fit for a particular purpose or non-infringing. The entire risk
as to the quality and performance of the Covered Software is with You. Should
any Covered Software prove defective in any respect, You (not any Contributor)
assume the cost of any necessary servicing, repair, or correction. This disclaimer
of warranty constitutes an essential part of this License. No use of any Covered
Software is authorized under this License except under this disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including
negligence), contract, or otherwise, shall any Contributor, or anyone who
distributes Covered Software as permitted above, be liable to You for any
direct, indirect, special, incidental, or consequential damages of any character
including, without limitation, damages for lost profits, loss of goodwill,
work stoppage, computer failure or malfunction, or any and all other commercial
damages or losses, even if such party shall have been informed of the possibility
of such damages. This limitation of liability shall not apply to liability
for death or personal injury resulting from such party's negligence to the
extent applicable law prohibits such limitation. Some jurisdictions do not
allow the exclusion or limitation of incidental or consequential damages,
so this exclusion and limitation may not apply to You.
8. Litigation
Any litigation relating to this License may be brought only in the courts
of a jurisdiction where the defendant maintains its principal place of business
and such litigation shall be governed by laws of that jurisdiction, without
reference to its conflict-of-law provisions. Nothing in this Section shall
prevent a party's ability to bring cross-claims or counter-claims.
9. Miscellaneous
This License represents the complete agreement concerning the subject matter
hereof. If any provision of this License is held to be unenforceable, such
provision shall be reformed only to the extent necessary to make it enforceable.
Any law or regulation which provides that the language of a contract shall
be construed against the drafter shall not be used to construe this License
against a Contributor.
10. Versions of the License
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section 10.3,
no one other than the license steward has the right to modify or publish new
versions of this License. Each version will be given a distinguishing version
number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version of
the License under which You originally received the Covered Software, or under
the terms of any subsequent version published by the license steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to create
a new license for such software, you may create and use a modified version
of this License if you rename the license and remove any references to the
name of the license steward (except to note that such modified license differs
from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
If You choose to distribute Source Code Form that is Incompatible With Secondary
Licenses under the terms of this version of the License, the notice described
in Exhibit B of this License must be attached. Exhibit A - Source Code Form
License Notice
This Source Code Form is subject to the terms of the Mozilla Public License,
v. 2.0. If a copy of the MPL was not distributed with this file, You can obtain
one at http://mozilla.org/MPL/2.0/.
If it is not possible or desirable to put the notice in a particular file,
then You may include the notice in a location (such as a LICENSE file in a
relevant directory) where a recipient would be likely to look for such a notice.
You may add additional accurate notices of copyright ownership.
Exhibit B - "Incompatible With Secondary Licenses" Notice
This Source Code Form is "Incompatible With Secondary Licenses", as defined
by the Mozilla Public License, v. 2.0.

# git-version.go
Use git tags to add semver to your go package.
```txt
Goal: Either use an exact version like v1.0.0
or translate the git version like v1.0.0-4-g0000000
to a semver like v1.0.1-pre4+g0000000
Fail gracefully when git repo isn't available.
```
# Demo
Generate an `xversion.go` file:
```bash
go run git.rootprojects.org/root/go-gitver
cat xversion.go
```
<small>**Note**: The file is named `xversion.go` by default so that the
generated file's `init()` will come later, and thus take priority, over
most other files.</small>
See `go-gitver`s self-generated version:
```bash
go run git.rootprojects.org/root/go-gitver version
```
# QuickStart
Add this to the top of your main file:
```go
//go:generate go run -mod=vendor git.rootprojects.org/root/go-gitver
```
Add a file that imports go-gitver (for versioning)
```go
// +build tools
package example
import _ "git.rootprojects.org/root/go-gitver"
```
Change you build instructions to be something like this:
```bash
go mod vendor
go generate -mod=vendor ./...
go build -mod=vendor -o example cmd/example/*.go
```
You don't have to use `mod vendor`, but I highly recommend it.
# Options
```
version print version and exit
--fail exit with non-zero status code on failure
--package <name> will set the package name
--outfile <name> will replace `xversion.go` with the given file path
```
ENVs
```
# Alias for --fail
GITVER_FAIL=true
```
For example:
```go
//go:generate go run -mod=vendor git.rootprojects.org/root/go-gitver --fail
```
```bash
go run -mod=vendor git.rootprojects.org/root/go-gitver version
```
# Usage
See `examples/basic`
1. Create a `tools` package in your project
2. Guard it against regular builds with `// +build tools`
3. Include `_ "git.rootprojects.org/root/go-gitver"` in the imports
4. Declare `var GitRev, GitVersion, GitTimestamp string` in your `package main`
5. Include `//go:generate go run -mod=vendor git.rootprojects.org/root/go-gitver` as well
`tools/tools.go`:
```go
// +build tools
// This is a dummy package for build tooling
package tools
import (
_ "git.rootprojects.org/root/go-gitver"
)
```
`main.go`:
```go
//go:generate go run git.rootprojects.org/root/go-gitver --fail
package main
import "fmt"
var (
GitRev = "0000000"
GitVersion = "v0.0.0-pre0+0000000"
GitTimestamp = "0000-00-00T00:00:00+0000"
)
func main() {
fmt.Println(GitRev)
fmt.Println(GitVersion)
fmt.Println(GitTimestamp)
}
```
If you're using `go mod vendor` (which I highly recommend that you do),
you'd modify the `go:generate` ever so slightly:
```go
//go:generate go run -mod=vendor git.rootprojects.org/root/go-gitver --fail
```
The only reason I didn't do that in the example is that I'd be included
the repository in itself and that would be... weird.
# Why a tools package?
> import "git.rootprojects.org/root/go-gitver" is a program, not an importable package
Having a tools package with a build tag that you don't use is a nice way to add exact
versions of a command package used for tooling to your `go.mod` with `go mod tidy`,
without getting the error above.
# git: behind the curtain
These are the commands that are used under the hood to produce the versions.
Shows the git tag + description. Assumes that you're using the semver format `v1.0.0` for your base tags.
```bash
git describe --tags --dirty --always
# v1.0.0
# v1.0.0-1-g0000000
# v1.0.0-dirty
```
Show the commit date (when the commit made it into the current tree).
Internally we use the current date when the working tree is dirty.
```bash
git show v1.0.0-1-g0000000 --format=%cd --date=format:%Y-%m-%dT%H:%M:%SZ%z --no-patch
# 2010-01-01T20:30:00Z-0600
# fatal: ambiguous argument 'v1.0.0-1-g0000000-dirty': unknown revision or path not in the working tree.
```
Shows the most recent commit.
```bash
git rev-parse HEAD
# 0000000000000000000000000000000000000000
```
