|
||||
1. Definitions
|
||||
|
||||
1.1. "Contributor" means each individual or legal entity that creates, contributes
|
||||
to the creation of, or owns Covered Software.
|
||||
|
||||
1.2. "Contributor Version" means the combination of the Contributions of others
|
||||
(if any) used by a Contributor and that particular Contributor's Contribution.
|
||||
|
||||
1.3. "Contribution" means Covered Software of a particular Contributor.
|
||||
|
||||
1.4. "Covered Software" means Source Code Form to which the initial Contributor
|
||||
has attached the notice in Exhibit A, the Executable Form of such Source Code
|
||||
Form, and Modifications of such Source Code Form, in each case including portions
|
||||
thereof.
|
||||
|
||||
1.5. "Incompatible With Secondary Licenses" means
|
||||
|
||||
(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
|
||||
|
||||
```txt
|
||||
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
|
||||
|
||||
```bash
|
||||
# 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
|
||||
```
|

|
||||
