=======
|
||||
|
||||
[]
|
||||
(https://travis-ci.org/davecgh/go-spew) [![Coverage Status]
|
||||
(https://coveralls.io/repos/davecgh/go-spew/badge.png?branch=master)]
|

|
||||
|
||||
Go-spew implements a deep pretty printer for Go data structures to aid in
|
||||
debugging. A comprehensive suite of tests with 100% test coverage is provided
|
||||
to ensure proper functionality. See `test_coverage.txt` for the gocov coverage
|
||||
report. Go-spew is licensed under the liberal ISC license, so it may be used in
|
||||
open source or commercial projects.
|
||||
|
||||
If you're interested in reading about how this package came to life and some
|
||||
of the challenges involved in providing a deep pretty printer, there is a blog
|
||||
post about it
|
||||
[here](https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
|
||||
|
||||
## Documentation
|
||||
|
||||
[]
|
||||
(http://godoc.org/github.com/davecgh/go-spew/spew)
|
||||
|
||||
Full `go doc` style documentation for the project can be viewed online without
|
||||
installing this package by using the excellent GoDoc site here:
|
||||
http://godoc.org/github.com/davecgh/go-spew/spew
|
||||
|
||||
You can also view the documentation locally once the package is installed with
|
||||
the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
|
||||
http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
$ go get -u github.com/davecgh/go-spew/spew
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
Add this import line to the file you're working in:
|
||||
|
||||
```Go
|
||||
import "github.com/davecgh/go-spew/spew"
|
||||
```
|
||||
|
||||
To dump a variable with full newlines, indentation, type, and pointer
|
||||
information use Dump, Fdump, or Sdump:
|
||||
|
||||
```Go
|
||||
spew.Dump(myVar1, myVar2, ...)
|
||||
spew.Fdump(someWriter, myVar1, myVar2, ...)
|
||||
str := spew.Sdump(myVar1, myVar2, ...)
|
||||
```
|
||||
|
||||
Alternatively, if you would prefer to use format strings with a compacted inline
|
||||
printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
|
||||
compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
|
||||
and pointer addresses):
|
||||
|
||||
```Go
|
||||
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
|
||||
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
|
||||
```
|
||||
|
||||
## Debugging a Web Application Example
|
||||
|
||||
Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
|
||||
|
||||
```Go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"html"
|
||||
"net/http"
|
||||
|
||||
"github.com/davecgh/go-spew/spew"
|
||||
)
|
||||
|
||||
func handler(w http.ResponseWriter, r *http.Request) {
|
||||
w.Header().Set("Content-Type", "text/html")
|
||||
fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
|
||||
fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
|
||||
}
|
||||
|
||||
func main() {
|
||||
http.HandleFunc("/", handler)
|
||||
http.ListenAndServe(":8080", nil)
|
||||
}
|
||||
```
|
||||
|
||||
## Sample Dump Output
|
||||
|
||||
```
|
||||
(main.Foo) {
|
||||
unexportedField: (*main.Bar)(0xf84002e210)({
|
||||
flag: (main.Flag) flagTwo,
|
||||
data: (uintptr) <nil>
|
||||
}),
|
||||
ExportedField: (map[interface {}]interface {}) {
|
||||
(string) "one": (bool) true
|
||||
}
|
||||
}
|
||||
([]uint8) {
|
||||
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
|
||||
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
|
||||
00000020 31 32 |12|
|
||||
}
|
||||
```
|
||||
|
||||
## Sample Formatter Output
|
||||
|
||||
Double pointer to a uint8:
|
||||
```
|
||||
%v: <**>5
|
||||
%+v: <**>(0xf8400420d0->0xf8400420c8)5
|
||||
%#v: (**uint8)5
|
||||
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
|
||||
```
|
||||
|
||||
Pointer to circular struct with a uint8 field and a pointer to itself:
|
||||
```
|
||||
%v: <*>{1 <*><shown>}
|
||||
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
|
||||
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
|
||||
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
|
||||
```
|
||||
|
||||
## Configuration Options
|
||||
|
||||
Configuration of spew is handled by fields in the ConfigState type. For
|
||||
convenience, all of the top-level functions use a global state available via the
|
||||
spew.Config global.
|
||||
|
||||
It is also possible to create a ConfigState instance that provides methods
|
||||
equivalent to the top-level functions. This allows concurrent configuration
|
||||
options. See the ConfigState documentation for more details.
|
||||
|
||||
```
|
||||
* Indent
|
||||
String to use for each indentation level for Dump functions.
|
||||
It is a single space by default. A popular alternative is "\t".
|
||||
|
||||
* MaxDepth
|
||||
Maximum number of levels to descend into nested data structures.
|
||||
There is no limit by default.
|
||||
|
||||
* DisableMethods
|
||||
Disables invocation of error and Stringer interface methods.
|
||||
Method invocation is enabled by default.
|
||||
|
||||
* DisablePointerMethods
|
||||
Disables invocation of error and Stringer interface methods on types
|
||||
which only accept pointer receivers from non-pointer variables. This option
|
||||
relies on access to the unsafe package, so it will not have any effect when
|
||||
running in environments without access to the unsafe package such as Google
|
||||
App Engine or with the "disableunsafe" build tag specified.
|
||||
Pointer method invocation is enabled by default.
|
||||
|
||||
* ContinueOnMethod
|
||||
Enables recursion into types after invoking error and Stringer interface
|
||||
methods. Recursion after method invocation is disabled by default.
|
||||
|
||||
* SortKeys
|
||||
Specifies map keys should be sorted before being printed. Use
|
||||
this to have a more deterministic, diffable output. Note that
|
||||
only native types (bool, int, uint, floats, uintptr and string)
|
||||
and types which implement error or Stringer interfaces are supported,
|
||||
with other types sorted according to the reflect.Value.String() output
|
||||
which guarantees display stability. Natural map order is used by
|
||||
default.
|
||||
|
||||
* SpewKeys
|
||||
SpewKeys specifies that, as a last resort attempt, map keys should be
|
||||
spewed to strings and sorted by those strings. This is only considered
|
||||
if SortKeys is true.
|
||||
|
||||
```
|
||||
|
||||
## Unsafe Package Dependency
|
||||
|
||||
This package relies on the unsafe package to perform some of the more advanced
|
||||
features, however it also supports a "limited" mode which allows it to work in
|
||||
environments where the unsafe package is not available. By default, it will
|
||||
operate in this mode on Google App Engine. The "disableunsafe" build tag may
|
||||
also be specified to force the package to build without using the unsafe
|
||||
package.

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

||||
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

# Versioning Library for Go
|
||||
[](https://travis-ci.org/hashicorp/go-version)
|
||||
|
||||
go-version is a library for parsing versions and version constraints,
|
||||
and verifying versions against a set of constraints. go-version
|
||||
can sort a collection of versions properly, handles prerelease/beta
|
||||
versions, can increment versions, etc.
|
||||
|
||||
Versions used with go-version must follow [SemVer](http://semver.org/).
|
||||
|
||||
## Installation and Usage
|
||||
|
||||
Package documentation can be found on
|
||||
[GoDoc](http://godoc.org/github.com/hashicorp/go-version).
|
||||
|
||||
Installation can be done with a normal `go get`:
|
||||
|
||||
```
|
||||
$ go get github.com/hashicorp/go-version
|
||||
```
|
||||
|
||||
#### Version Parsing and Comparison
|
||||
|
||||
```go
|
||||
v1, err := version.NewVersion("1.2")
|
||||
v2, err := version.NewVersion("1.5+metadata")
|
||||
|
||||
// Comparison example. There is also GreaterThan, Equal, and just
|
||||
// a simple Compare that returns an int allowing easy >=, <=, etc.
|
||||
if v1.LessThan(v2) {
|
||||
fmt.Printf("%s is less than %s", v1, v2)
|
||||
}
|
||||
```
|
||||
|
||||
#### Version Constraints
|
||||
|
||||
```go
|
||||
v1, err := version.NewVersion("1.2")
|
||||
|
||||
// Constraints example.
|
||||
constraints, err := version.NewConstraint(">= 1.0, < 1.4")
|
||||
if constraints.Check(v1) {
|
||||
fmt.Printf("%s satisfies constraints %s", v1, constraints)
|
||||
}
|
||||
```
|
||||
|
||||
#### Version Sorting
|
||||
|
||||
```go
|
||||
versionsRaw := []string{"1.1", "0.7.1", "1.4-beta", "1.4", "2"}
|
||||
versions := make([]*version.Version, len(versionsRaw))
|
||||
for i, raw := range versionsRaw {
|
||||
v, _ := version.NewVersion(raw)
|
||||
versions[i] = v
|
||||
}
|
||||
|
||||
// After this, the versions are properly sorted
|
||||
sort.Sort(version.Collection(versions))
|
||||
```
|
||||
|
||||
