+
+
+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.
+

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at i@dario.im. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+# Mergo
+
+A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
+
+Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
+
+## Status
+
+It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc](https://github.com/imdario/mergo#mergo-in-the-wild).

+### Latest release
+
+[Release v0.3.4](https://github.com/imdario/mergo/releases/tag/v0.3.4).
+
+### Important note
+
+Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.
+
+If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).
+
+### Donations
+
+If Mergo is useful to you, consider buying me a coffee, a beer or making a monthly donation so I can keep building great free software. :heart_eyes:

+## Installation
+
+ go get github.com/imdario/mergo
+
+ // use in your .go code
+ import (
+ "github.com/imdario/mergo"
+ )
+
+## Usage
+
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are not considered zero values](https://golang.org/ref/spec#The_zero_value) either. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+```go
+if err := mergo.Merge(&dst, src); err != nil {
+ // ...
+}
+```
+
+Also, you can merge overwriting values using the transformer `WithOverride`.
+
+```go
+if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
+ // ...
+}
+```
+
+Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
+
+```go
+if err := mergo.Map(&dst, srcMap); err != nil {
+ // ...
+}
+```
+
+Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
+
+More information and examples in [godoc documentation](http://godoc.org/github.com/imdario/mergo).
+
+### Nice example
+
+```go
+package main
+
+import (
+ "fmt"
+ "github.com/imdario/mergo"
+)
+
+type Foo struct {
+ A string
+ B int64
+}
+
+func main() {
+ src := Foo{
+ A: "one",
+ B: 2,
+ }
+ dest := Foo{
+ A: "two",
+ }
+ mergo.Merge(&dest, src)
+ fmt.Println(dest)
+ // Will print
+ // {two 2}
+}
+```
+
+Note: if test are failing due missing package, please execute:
+
+ go get gopkg.in/yaml.v2
+
+### Transformers
+
+Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
+
+```go
+package main
+
+import (
+ "fmt"
+ "github.com/imdario/mergo"
+ "reflect"
+ "time"
+)
+
+type timeTransfomer struct {
+}
+
+func (t timeTransfomer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
+ if typ == reflect.TypeOf(time.Time{}) {
+ return func(dst, src reflect.Value) error {
+ if dst.CanSet() {
+ isZero := dst.MethodByName("IsZero")
+ result := isZero.Call([]reflect.Value{})
+ if result[0].Bool() {
+ dst.Set(src)
+ }
+ }
+ return nil
+ }
+ }
+ return nil
+}
+
+type Snapshot struct {
+ Time time.Time
+ // ...
+}
+
+func main() {
+ src := Snapshot{time.Now()}
+ dest := Snapshot{}
+ mergo.Merge(&dest, src, mergo.WithTransformers(timeTransfomer{}))
+ fmt.Println(dest)
+ // Will print
+ // { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
+}
+```
