+# Contributor Code of Conduct
+## Version 0.1.1 (adapted from 0.3b-angular)
+
+As contributors and maintainers of the Common Expression Language
+(CEL) project, we pledge to respect everyone who contributes by
+posting issues, updating documentation, submitting pull requests,
+providing feedback in comments, and any other activities.
+
+Communication through any of CEL's channels (GitHub, Gitter, IRC,
+mailing lists, Google+, Twitter, etc.) must be constructive and never
+resort to personal attacks, trolling, public or private harassment,
+insults, or other unprofessional conduct.
+
+We promise to extend courtesy and respect to everyone involved in this
+project regardless of gender, gender identity, sexual orientation,
+disability, age, race, ethnicity, religion, or level of experience. We
+expect anyone contributing to the project to do the same.
+
+If any member of the community violates this code of conduct, the
+maintainers of the CEL project may take action, removing issues,
+comments, and PRs or blocking accounts as deemed appropriate.
+
+If you are subject to or witness unacceptable behavior, or have any
+other concerns, please email us at
+[cel-conduct@google.com](mailto:cel-conduct@google.com).

+# How to Contribute
+
+We'd love to accept your patches and contributions to this project. There are a
+few guidelines you need to follow.
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution,
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult
+[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
+information on using pull requests.
+
+## What to expect from maintainers
+
+Expect maintainers to respond to new issues or pull requests within a week.
+For outstanding and ongoing issues and particularly for long-running
+pull requests, expect the maintainers to review within a week of a
+contributor asking for a new review. There is no commitment to resolution --
+merging or closing a pull request, or fixing or closing an issue -- because some
+issues will require more discussion than others.

+# Project Governance
+
+This document defines the governance process for the CEL language. CEL is
+Google-developed, but openly governed. Major contributors to the CEL
+specification and its corresponding implementations constitute the CEL
+Language Council. New members may be added by a unanimous vote of the
+Council.
+
+The MAINTAINERS.md file lists the members of the CEL Language Council, and
+unofficially indicates the "areas of expertise" of each member with respect
+to the publicly available CEL repos.
+
+## Code Changes
+
+Code changes must follow the standard pull request (PR) model documented in the
+CONTRIBUTING.md for each CEL repo. All fixes and features must be reviewed by a
+maintainer. The maintainer reserves the right to request that any feature
+request (FR) or PR be reviewed by the language council.
+
+## Syntax and Semantic Changes
+
+Syntactic and semantic changes must be reviewed by the CEL Language Council.
+Maintainers may also request language council review at their discretion.
+
+The review process is as follows:
+
+- Create a Feature Request in the CEL-Spec repo. The feature description will
+ serve as an abstract for the detailed design document.
+- Co-develop a design document with the Language Council.
+- Once the proposer gives the design document approval, the document will be
+ linked to the FR in the CEL-Spec repo and opened for comments to members of
+ the cel-lang-discuss@googlegroups.com.
+- The Language Council will review the design doc at the next council meeting
+ (once every three weeks) and the council decision included in the document.
+
+If the proposal is approved, the spec will be updated by a maintainer (if
+applicable) and a rationale will be included in the CEL-Spec wiki to ensure
+future developers may follow CEL's growth and direction over time.
+
+Approved proposals may be implemented by the proposer or by the maintainers as
+the parties see fit. At the discretion of the maintainer, changes from the
+approved design are permitted during implementation if they improve the user
+experience and clarity of the feature.

+# Common Expression Language
+
+The Common Expression Language (CEL) implements common semantics for expression
+evaluation, enabling different applications to more easily interoperate.
+
+Key Applications
+
+* Security policy: organizations have complex infrastructure and need common
+ tooling to reason about the system as a whole
+* Protocols: expressions are a useful data type and require interoperability
+ across programming languages and platforms.
+
+
+Guiding philosophy:
+
+1. Keep it small & fast.
+ * CEL evaluates in linear time, is mutation free, and not Turing-complete.
+ This limitation is a feature of the language design, which allows the
+ implementation to evaluate orders of magnitude faster than equivalently
+ sandboxed JavaScript.
+2. Make it extensible.
+ * CEL is designed to be embedded in applications, and allows for
+ extensibility via its context which allows for functions and data to be
+ provided by the software that embeds it.
+3. Developer-friendly.
+ * The language is approachable to developers. The initial spec was based
+ on the experience of developing Firebase Rules and usability testing
+ many prior iterations.
+ * The library itself and accompanying toolings should be easy to adopt by
+ teams that seek to integrate CEL into their platforms.
+
+The required components of a system that supports CEL are:
+
+* The textual representation of an expression as written by a developer. It is
+ of similar syntax to expressions in C/C++/Java/JavaScript
+* A representation of the program's abstract syntax tree (AST).
+* A compiler library that converts the textual representation to the binary
+ representation. This can be done ahead of time (in the control plane) or
+ just before evaluation (in the data plane).
+* A context containing one or more typed variables, often protobuf messages.
+ Most use-cases will use `attribute_context.proto`
+* An evaluator library that takes the binary format in the context and
+ produces a result, usually a Boolean.
+
+For use cases which require persistence or cross-process communcation, it is
+highly recommended to serialize the type-checked expression as a protocol
+buffer. The CEL team will maintains canonical protocol buffers for ASTs and
+will keep these versions identical and wire-compatible in perpetuity:
+
+* [CEL canonical](https://github.com/google/cel-spec/tree/master/proto/cel/expr)
+* [CEL v1alpha1](https://github.com/googleapis/googleapis/tree/master/google/api/expr/v1alpha1)
+
+
+Example of boolean conditions and object construction:
+
+``` c
+// Condition
+account.balance >= transaction.withdrawal
+ || (account.overdraftProtection
+ && account.overdraftLimit >= transaction.withdrawal - account.balance)
+
+// Object construction
+common.GeoPoint{ latitude: 10.0, longitude: -5.5 }
+```

+# go-winio [](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
+
+This repository contains utilities for efficiently performing Win32 IO operations in
+Go. Currently, this is focused on accessing named pipes and other file handles, and
+for using named pipes as a net transport.
+
+This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
+to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
+newer operating systems. This is similar to the implementation of network sockets in Go's net
+package.
+
+Please see the LICENSE file for licensing information.
+
+## Contributing
+
+This project welcomes contributions and suggestions.
+Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
+you have the right to, and actually do, grant us the rights to use your contribution.
+For details, visit [Microsoft CLA](https://cla.microsoft.com).
+
+When you submit a pull request, a CLA-bot will automatically determine whether you need to
+provide a CLA and decorate the PR appropriately (e.g., label, comment).
+Simply follow the instructions provided by the bot.
+You will only need to do this once across all repos using our CLA.
+
+Additionally, the pull request pipeline requires the following steps to be performed before
+mergining.
+
+### Code Sign-Off
+
+We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+
+Please see [the developer certificate](https://developercertificate.org) for more info,
+as well as to make sure that you can attest to the rules listed.
+Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+ "go.lintTool": "golangci-lint",
+ "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run ./...
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+
+This can be done for the entire repo:
+
+```shell
+> go generate ./...
+```
+

+## Reporting Security Issues
+
+**Please do not report security vulnerabilities through public GitHub issues.**
+
+Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/opensource/security/create-report).
+
+If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com). If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/opensource/security/pgpkey).
+
+You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://aka.ms/opensource/security/msrc).
+
+Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
+
+ * Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
+ * Full paths of source file(s) related to the manifestation of the issue
+ * The location of the affected source code (tag/branch/commit or direct URL)
+ * Any special configuration required to reproduce the issue
+ * Step-by-step instructions to reproduce the issue
+ * Proof-of-concept or exploit code (if possible)
+ * Impact of the issue, including how an attacker might exploit the issue
+
+This information will help us triage your report more quickly.
+
+If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Please visit our [Microsoft Bug Bounty Program](https://aka.ms/opensource/security/bounty) page for more details about our active programs.
+
+## Preferred Languages

+# hnslib
+
+This package provides the Golang interface for accessing Windows HCN APIs to manage entities within the Host Network Service (HNS), which serves as the server container networking component in Windows. While it is mainly utilized by the Windows KubeProxy component in Kubernetes, it is also available for use in other projects, such as Azure CNI, Windows CNI, Calico CNI, Flannel CNI, Azure NPM, and more.
+
+## Building
+
+This project is imported by KubeProxy, Kubelet etc. for building binaries.
+
+## Contributing
+
+This project welcomes contributions and suggestions. Most contributions require you to agree to a
+Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant us
+the rights to use your contribution. For details, visit [Microsoft CLA](https://cla.microsoft.com).
+
+When you submit a pull request, a CLA-bot will automatically determine whether you need to provide
+a CLA and decorate the PR appropriately (e.g., label, comment). Simply follow the instructions
+provided by the bot. You will only need to do this once across all repos using our CLA.
+
+We require that contributors sign their commits
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+We also require that contributors sign their commits using using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+
+Please see [the developer certificate](https://developercertificate.org) for more info,
+as well as to make sure that you can attest to the rules listed.
+Our CI uses the [DCO Github app](https://github.com/apps/dco) to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+Since `./test` is a separate Go module, the linter is run from both the root and the
+`test` directories. Additionally, the linter is run with `GOOS` set to both `windows` and
+`linux`.
+
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+ "go.lintTool": "golangci-lint",
+ "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed][lint-install] and run locally:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run
+```
+
+To run across the entire repo for both `GOOS=windows` and `linux`:
+
+```powershell
+> foreach ( $goos in ('windows', 'linux') ) {
+ foreach ( $repo in ('.', 'test') ) {
+ pwsh -Command "cd $repo && go env -w GOOS=$goos && golangci-lint.exe run --verbose"
+ }
+}
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+Similar to the [linting stage](#linting), `go generate` is run in root Go modules.
+
+This can be done via:
+
+```shell
+> go generate ./...
+> cd test && go generate ./...
+```

+---
+layout: code-of-conduct
+version: v1.0
+---
+
+This code of conduct outlines our expectations for participants within the **NYTimes/gziphandler** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community.
+
+Our open source community strives to:
+
+* **Be friendly and patient.**
+* **Be welcoming**: We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability.
+* **Be considerate**: Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language.
+* **Be respectful**: Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one.
+* **Be careful in the words that we choose**: we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable.
+* **Try to understand why we disagree**: Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.
+
+## Definitions
+
+Harassment includes, but is not limited to:
+
+- Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, race, age, regional discrimination, political or religious affiliation
+- Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment
+- Deliberate misgendering. This includes deadnaming or persistently using a pronoun that does not correctly reflect a person's gender identity. You must address people by the name they give you when not addressing them by their username or handle
+- Physical contact and simulated physical contact (eg, textual descriptions like “*hug*†or “*backrub*â€) without consent or after a request to stop
+- Threats of violence, both physical and psychological
+- Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm
+- Deliberate intimidation
+- Stalking or following
+- Harassing photography or recording, including logging online activity for harassment purposes
+- Sustained disruption of discussion
+- Unwelcome sexual attention, including gratuitous or off-topic sexual images or behaviour
+- Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others
+- Continued one-on-one communication after requests to cease
+- Deliberate “outing†of any aspect of a person’s identity without their consent except as necessary to protect others from intentional abuse
+- Publication of non-harassing private communication
+
+Our open source community prioritizes marginalized people’s safety over privileged people’s comfort. We will not act on complaints regarding:
+
+- ‘Reverse’ -isms, including ‘reverse racism,’ ‘reverse sexism,’ and ‘cisphobia’
+- Reasonable communication of boundaries, such as “leave me alone,†“go away,†or “I’m not discussing this with youâ€
+- Refusal to explain or debate social justice concepts
+- Communicating in a ‘tone’ you don’t find congenial
+- Criticizing racist, sexist, cissexist, or otherwise oppressive behavior or assumptions
+
+
+### Diversity Statement
+
+We encourage everyone to participate and are committed to building a community for all. Although we will fail at times, we seek to treat everyone both as fairly and equally as possible. Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong.
+
+Although this list cannot be exhaustive, we explicitly honor diversity in age, gender, gender identity or expression, culture, ethnicity, language, national origin, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, and technical ability. We will not tolerate discrimination based on any of the protected
+characteristics above, including participants with disabilities.
+
+### Reporting Issues
+
+If you experience or witness unacceptable behavior—or have any other concerns—please report it by contacting us via **code@nytimes.com**. All reports will be handled with discretion. In your report please include:
+
+- Your contact information.
+- Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional witnesses, please
+include them as well. Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly available record (e.g. a mailing list archive or a public IRC logger), please include a link.
+- Any additional information that may be helpful.
+
+After filing a report, a representative will contact you personally, review the incident, follow up with any additional questions, and make a decision as to how to respond. If the person who is harassing you is part of the response team, they will recuse themselves from handling your incident. If the complaint originates from a member of the response team, it will be handled by a different member of the response team. We will respect confidentiality requests for the purpose of protecting victims of abuse.
+
+### Attribution & Acknowledgements

+We all stand on the shoulders of giants across many open source communities. We'd like to thank the communities and projects that established code of conducts and diversity statements as our inspiration:

+# Contributing to NYTimes/gziphandler
+
+This is an open source project started by handful of developers at The New York Times and open to the entire Go community.
+
+We really appreciate your help!
+
+## Filing issues
+
+When filing an issue, make sure to answer these five questions:
+
+1. What version of Go are you using (`go version`)?
+2. What operating system and processor architecture are you using?
+3. What did you do?
+4. What did you expect to see?
+5. What did you see instead?
+
+## Contributing code
+
+Before submitting changes, please follow these guidelines:
+
+1. Check the open issues and pull requests for existing discussions.
+2. Open an issue to discuss a new feature.
+3. Write tests.
+4. Make sure code follows the ['Go Code Review Comments'](https://github.com/golang/go/wiki/CodeReviewComments).
+5. Make sure your changes pass `go test`.
+6. Make sure the entire test suite passes locally and on Travis CI.
+7. Open a Pull Request.
+8. [Squash your commits](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html) after receiving feedback and add a [great commit message](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).

+Gzip Handler
+============
+
+This is a tiny Go package which wraps HTTP handlers to transparently gzip the
+response body, for clients which support it. Although it's usually simpler to
+leave that to a reverse proxy (like nginx or Varnish), this package is useful
+when that's undesirable.
+
+## Install
+```bash
+go get -u github.com/NYTimes/gziphandler
+```
+
+## Usage
+
+Call `GzipHandler` with any handler (an object which implements the
+`http.Handler` interface), and it'll return a new handler which gzips the
+response. For example:
+
+```go
+package main
+
+import (
+ "io"
+ "net/http"
+ "github.com/NYTimes/gziphandler"
+)
+
+func main() {
+ withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+ w.Header().Set("Content-Type", "text/plain")
+ io.WriteString(w, "Hello, World")
+ })
+
+ withGz := gziphandler.GzipHandler(withoutGz)
+
+ http.Handle("/", withGz)
+ http.ListenAndServe("0.0.0.0:8000", nil)
+}
+```

+# ANTLR4 Go Runtime Module Repo
+
+IMPORTANT: Please submit PRs via a clone of the https://github.com/antlr/antlr4 repo, and not here.
+
+ - Do not submit PRs or any change requests to this repo
+ - This repo is read only and is updated by the ANTLR team to create a new release of the Go Runtime for ANTLR
+ - This repo contains the Go runtime that your generated projects should import
+
+## Introduction
+
+This repo contains the official modules for the Go Runtime for ANTLR. It is a copy of the runtime maintained
+at: https://github.com/antlr/antlr4/tree/master/runtime/Go/antlr and is automatically updated by the ANTLR team to create
+the official Go runtime release only. No development work is carried out in this repo and PRs are not accepted here.
+
+The dev branch of this repo is kept in sync with the dev branch of the main ANTLR repo and is updated periodically.
+
+### Why?
+
+The `go get` command is unable to retrieve the Go runtime when it is embedded so
+deeply in the main repo. A `go get` against the `antlr/antlr4` repo, while retrieving the correct source code for the runtime,
+does not correctly resolve tags and will create a reference in your `go.mod` file that is unclear, will not upgrade smoothly and
+causes confusion.
+
+For instance, the current Go runtime release, which is tagged with v4.13.0 in `antlr/antlr4` is retrieved by go get as:
+
+```sh
+require (
+ github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.0.0-20230219212500-1f9a474cc2dc
+)
+```
+
+Where you would expect to see:
+
+```sh
+require (
+ github.com/antlr/antlr4/runtime/Go/antlr/v4 v4.13.0
+)
+```
+
+The decision was taken to create a separate org in a separate repo to hold the official Go runtime for ANTLR and
+from whence users can expect `go get` to behave as expected.
+
+
+# Documentation
+Please read the official documentation at: https://github.com/antlr/antlr4/blob/master/doc/index.md for tips on
+migrating existing projects to use the new module location and for information on how to use the Go runtime in
+general.

+Package antlr implements the Go version of the ANTLR 4 runtime.
+
+# The ANTLR Tool
+
+ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing,
+or translating structured text or binary files. It's widely used to build languages, tools, and frameworks.
+From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface
+(or visitor) that makes it easy to respond to the recognition of phrases of interest.
+
+# Go Runtime
+
+At version 4.11.x and prior, the Go runtime was not properly versioned for go modules. After this point, the runtime
+source code to be imported was held in the `runtime/Go/antlr/v4` directory, and the go.mod file was updated to reflect the version of
+ANTLR4 that it is compatible with (I.E. uses the /v4 path).
+
+However, this was found to be problematic, as it meant that with the runtime embedded so far underneath the root
+of the repo, the `go get` and related commands could not properly resolve the location of the go runtime source code.
+This meant that the reference to the runtime in your `go.mod` file would refer to the correct source code, but would not
+list the release tag such as @4.12.0 - this was confusing, to say the least.
+
+As of 4.12.1, the runtime is now available as a go module in its own repo, and can be imported as `github.com/antlr4-go/antlr`
+(the go get command should also be used with this path). See the main documentation for the ANTLR4 project for more information,
+which is available at [ANTLR docs]. The documentation for using the Go runtime is available at [Go runtime docs].
+
+This means that if you are using the source code without modules, you should also use the source code in the [new repo].
+Though we highly recommend that you use go modules, as they are now idiomatic for Go.
+
+I am aware that this change will prove Hyrum's Law, but am prepared to live with it for the common good.

+
+# Code Generation
+
+ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a
+runtime library, written specifically to support the generated code in the target language. This library is the
+runtime for the Go target.
+
+To generate code for the go target, it is generally recommended to place the source grammar files in a package of
+their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory
+it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean
+that the antlr tool JAR file will be checked in to your source code control though, so you are, of course, free to use any other
+way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in
+your IDE, or configuration in your CI system. Checking in the jar does mean that it is easy to reproduce the build as
+it was at any point in its history.
+
+Here is a general/recommended template for an ANTLR based recognizer in Go:
+
+ .
+ ├── parser
+ │ ├── mygrammar.g4
+ │ ├── antlr-4.12.1-complete.jar
+ │ ├── generate.go
+ │ └── generate.sh
+ ├── parsing - generated code goes here
+ │ └── error_listeners.go
+ ├── go.mod
+ ├── go.sum
+ ├── main.go
+ └── main_test.go
+
+Make sure that the package statement in your grammar file(s) reflects the go package the generated code will exist in.
+
+The generate.go file then looks like this:
+
+ package parser
+
+ //go:generate ./generate.sh
+
+And the generate.sh file will look similar to this:
+
+ #!/bin/sh
+
+ alias antlr4='java -Xmx500M -cp "./antlr4-4.12.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
+ antlr4 -Dlanguage=Go -no-visitor -package parsing *.g4
+
+depending on whether you want visitors or listeners or any other ANTLR options. Not that another option here
+is to generate the code into a
+
+From the command line at the root of your source package (location of go.mo)d) you can then simply issue the command:
+
+ go generate ./...
+
+Which will generate the code for the parser, and place it in the parsing package. You can then use the generated code
+by importing the parsing package.
+
+There are no hard and fast rules on this. It is just a recommendation. You can generate the code in any way and to anywhere you like.

+// or a block with an empty alternative), then the expected set includes what follows

+//
+// classfunc : 'class' ID '{' member* '}'
+//
+// input with an extra token between members would force the parser to
+// consume until it found the next class definition rather than the next
+// member definition of the current class.
+//
+// This functionality cost a bit of effort because the parser has to

+// GetErrorRecoverySet computes the error recovery set for the current rule. During

+// enclosing rule. See LinearApproximator.FIRST().
+//
+// This local follow set only includes tokens
+// from within the rule i.e., the FIRST computation done by
+// ANTLR stops at the end of a rule.
+//
+// # Example
+//
+// When you find a "no viable alt exception", the input is not
+// consistent with any of the alternatives for rule r. The best
+// thing to do is to consume tokens until you see something that
+// can legally follow a call to r or any rule that called r.
+// You don't want the exact set of viable next tokens because the
+// input might just be missing a token--you might consume the
+// rest of the input looking for one of the missing tokens.
+//
+// Consider the grammar:
+//
+// a : '[' b ']'
+// | '(' b ')'
+// ;
+//
+// b : c '^' INT
+// ;
+//
+// c : ID
+// | INT
+// ;
+//
+// At each rule invocation, the set of tokens that could follow
+// that rule is pushed on a stack. Here are the various
+// context-sensitive follow sets:
+//
+// FOLLOW(b1_in_a) = FIRST(']') = ']'
+// FOLLOW(b2_in_a) = FIRST(')') = ')'
+// FOLLOW(c_in_b) = FIRST('^') = '^'
+//
+// Upon erroneous input “[]â€, the call chain is
+//
+// a → b → c
+//
+// and, hence, the follow context stack is:
+//
+// Depth Follow set Start of rule execution
+// 0 a (from main())
+// 1 ']' b
+// 2 '^' c
+//
+// Notice that ')' is not included, because b would have to have
+// been called from a different context in rule a for ')' to be
+// included.
+//
+// For error recovery, we cannot consider FOLLOW(c)
+// (context-sensitive or otherwise). We need the combined set of
+// all context-sensitive FOLLOW sets - the set of all tokens that
+// could follow any reference in the call chain. We need to
+// reSync to one of those tokens. Note that FOLLOW(c)='^' and if
+// we reSync'd to that token, we'd consume until EOF. We need to
+// Sync to context-sensitive FOLLOWs for a, b, and c:
+//
+// {']','^'}
+//
+// In this case, for input "[]", LA(1) is ']' and in the set, so we would
+// not consume anything. After printing an error, rule c would
+// return normally. Rule b would not find the required '^' though.
+// At this point, it gets a mismatched token error and panics an
+// exception (since LA(1) is not in the viable following token
+// set). The rule exception handler tries to recover, but finds
+// the same recovery set and doesn't consume anything. Rule b
+// exits normally returning to rule a. Now it finds the ']' (and
+// with the successful Match exits errorRecovery mode).
+//
+// So, you can see that the parser walks up the call chain looking
+// for the token that was a member of the recovery set.
+//
+// Errors are not generated in errorRecovery mode.
+//
+// ANTLR's error recovery mechanism is based upon original ideas:
+//
+// [Algorithms + Data Structures = Programs] by Niklaus Wirth and
+// [A note on error recovery in recursive descent parsers].
+//
+// Later, Josef Grosch had some good ideas in [Efficient and Comfortable Error Recovery in Recursive Descent
+// Parsers]
+//
+// Like Grosch I implement context-sensitive FOLLOW sets that are combined at run-time upon error to avoid overhead
+// during parsing. Later, the runtime Sync was improved for loops/sub-rules see [Sync] docs
+//

+// Error state was reached during [ATN] simulation.
+//
+// The default implementation of this method uses the following
+// algorithm to identify an [ATN] configuration which successfully parsed the
+// decision entry rule. Choosing such an alternative ensures that the
+// [ParserRuleContext] returned by the calling rule will be complete
+// and valid, and the syntax error will be Reported later at a more
+// localized location.
+//
+// - If a syntactically valid path or paths reach the end of the decision rule, and
+// they are semantically valid if predicated, return the min associated alt.
+// - Else, if a semantically invalid but syntactically valid path exist
+// or paths exist, return the minimum associated alt.
+// - Otherwise, return [ATNInvalidAltNumber].
+//
+// In some scenarios, the algorithm described above could predict an
+// alternative which will result in a [FailedPredicateException] in
+// the parser. Specifically, this could occur if the only configuration
+// capable of successfully parsing to the end of the decision rule is
+// blocked by a semantic predicate. By choosing this alternative within
+// [AdaptivePredict] instead of panic a [NoViableAltException], the resulting
+// [FailedPredicateException] in the parser will identify the specific
+// predicate which is preventing the parser from successfully parsing the
+// decision rule, which helps developers identify and correct logic errors

+// [6|2|[]].
+//
+// The key is that we have a single state that has config's only associated

+// among the configurations are all non-epsilon transitions. That means
+// we don't consider any conflicts that include alternative 2. So, we
+// ignore the conflict between alts 1 and 2. We ignore a set of
+// conflicting alts when there is an intersection with an alternative
+// associated with a single alt state in the state config-list map.
+//
+// It's also the case that we might have two conflicting configurations but
+// also a 3rd non-conflicting configuration for a different alternative:
+//
+// [1|1|[], 1|2|[], 8|3|[]].
+//
+// This can come about from grammar:
+//
+// a : A | A | A B
+//
+// After Matching input A, we reach the stop state for rule A, state 1.
+// State 8 is the state right before B. Clearly alternatives 1 and 2
+// conflict and no amount of further lookahead will separate the two.
+// However, alternative 3 will be able to continue, so we do not
+// stop working on this state.
+//
+// In the previous example, we're concerned
+// with states associated with the conflicting alternatives. Here alt
+// 3 is not associated with the conflicting configs, but since we can continue

+// # Pure SLL Parsing

+// # Predicates in SLL+LL Parsing

+// SLL decisions don't evaluate predicates until after they reach [DFA] stop
+// states because they need to create the [DFA] cache that works in all

+// during start state computation, so it can ignore predicates thereafter.
+// This means that SLL termination detection can totally ignore semantic
+// predicates.

+// Can we stop looking ahead during [ATN] simulation or is there some

+// consuming more input? Even if there are partial conflicts, we might know
+// that everything is going to resolve to the same minimum alternative. That
+// means we can stop since no more lookahead will change that fact. On the
+// other hand, there might be multiple conflicts that resolve to different
+// minimums. That means we need more look ahead to decide which of those
+// alternatives we should predict.
+//
+// The basic idea is to split the set of configurations 'C', into
+// conflicting subsets (s, _, ctx, _) and singleton subsets with
+// non-conflicting configurations. Two configurations conflict if they have
+// identical [ATNConfig].state and [ATNConfig].context values
+// but a different [ATNConfig].alt value, e.g.
+//
+// (s, i, ctx, _)
+//
+// and
+//
+// (s, j, ctx, _) ; for i != j
+//
+// Reduce these configuration subsets to the set of possible alternatives.
+// You can compute the alternative subsets in one pass as follows:
+//
+// A_s,ctx = {i | (s, i, ctx, _)}
+//
+// for each configuration in C holding s and ctx fixed.
+//
+// Or in pseudo-code:
+//
+// for each configuration c in C:
+// map[c] U = c.ATNConfig.alt alt // map hash/equals uses s and x, not alt and not pred
+//
+// The values in map are the set of
+//
+// A_s,ctx
+//
+// sets.
+//
+// If
+//
+// |A_s,ctx| = 1
+//
+// then there is no conflict associated with s and ctx.
+//
+// Reduce the subsets to singletons by choosing a minimum of each subset. If
+// the union of these alternative subsets is a singleton, then no amount of
+// further lookahead will help us. We will always pick that alternative. If,
+// however, there is more than one alternative, then we are uncertain which
+// alternative to predict and must continue looking for resolution. We may
+// or may not discover an ambiguity in the future, even if there are no
+// conflicting subsets this round.
+//
+// The biggest sin is to terminate early because it means we've made a
+// decision but were uncertain as to the eventual outcome. We haven't used
+// enough lookahead. On the other hand, announcing a conflict too late is no
+// big deal; you will still have the conflict. It's just inefficient. It
+// might even look until the end of file.
+//
+// No special consideration for semantic predicates is required because
+// predicates are evaluated on-the-fly for full LL prediction, ensuring that
+// no configuration contains a semantic context during the termination
+// check.
+//
+// # Conflicting Configs
+//
+// Two configurations:
+//
+// (s, i, x) and (s, j, x')
+//
+// conflict when i != j but x = x'. Because we merge all
+// (s, i, _) configurations together, that means that there are at
+// most n configurations associated with state s for
+// n possible alternatives in the decision. The merged stacks
+// complicate the comparison of configuration contexts x and x'.
+//
+// Sam checks to see if one is a subset of the other by calling
+// merge and checking to see if the merged result is either x or x'.
+// If the x associated with lowest alternative i
+// is the superset, then i is the only possible prediction since the
+// others resolve to min(i) as well. However, if x is
+// associated with j > i then at least one stack configuration for
+// j is not in conflict with alternative i. The algorithm
+// should keep going, looking for more lookahead due to the uncertainty.
+//
+// For simplicity, I'm doing an equality check between x and
+// x', which lets the algorithm continue to consume lookahead longer
+// than necessary. The reason I like the equality is of course the
+// simplicity but also because that is the test you need to detect the
+// alternatives that are actually in conflict.
+//
+// # Continue/Stop Rule
+//
+// Continue if the union of resolved alternative sets from non-conflicting and
+// conflicting alternative subsets has more than one alternative. We are
+// uncertain about which alternative to predict.
+//
+// The complete set of alternatives,
+//
+// [i for (_, i, _)]
+//
+// tells us which alternatives are still in the running for the amount of input we've
+// consumed at this point. The conflicting sets let us to strip away
+// configurations that won't lead to more states because we resolve
+// conflicts to the configuration with a minimum alternate for the
+// conflicting set.
+//
+// Cases
+//
+// - no conflicts and more than 1 alternative in set => continue
+// - (s, 1, x), (s, 2, x), (s, 3, z), (s', 1, y), (s', 2, y) yields non-conflicting set

+// {1} ∪ conflicting sets min({1,2}) ∪ min({1,2}) = {1} => stop and predict 1
+// - (s, 1, x), (s, 2, x), (s', 1, y), (s', 2, y) yields conflicting, reduced sets
+// {1} ∪ {1} = {1} => stop and predict 1, can announce ambiguity {1,2}
+// - (s, 1, x), (s, 2, x), (s', 2, y), (s', 3, y) yields conflicting, reduced sets

+// - (s, 1, x), (s, 2, x), (s', 2, y), (s', 3, y) yields conflicting, reduced sets

+// - (s, 1, x), (s, 2, x), (s', 3, y), (s', 4, y) yields conflicting, reduced sets
+// {1} ∪ {3} = {1,3} => continue
+//
+// # Exact Ambiguity Detection
+//

+//
+// and

+// Useful for rewriting out a buffered input token stream after doing some
+// augmentation or other manipulations on it.
+
+//
+// You can insert stuff, replace, and delete chunks. Note that the operations
+// are done lazily--only if you convert the buffer to a {@link String} with
+// {@link TokenStream#getText()}. This is very efficient because you are not
+// moving data around all the time. As the buffer of tokens is converted to
+// strings, the {@link #getText()} method(s) scan the input token stream and
+// check to see if there is an operation at the current index. If so, the
+// operation is done and then normal {@link String} rendering continues on the
+// buffer. This is like having multiple Turing machine instruction streams
+// (programs) operating on a single input tape. :)
+//
+
+// This rewriter makes no modifications to the token stream. It does not ask the
+// stream to fill itself up nor does it advance the input cursor. The token
+// stream {@link TokenStream#index()} will return the same value before and
+// after any {@link #getText()} call.
+
+//
+// The rewriter only works on tokens that you have in the buffer and ignores the
+// current input cursor. If you are buffering tokens on-demand, calling
+// {@link #getText()} halfway through the input will only do rewrites for those
+// tokens in the first half of the file.
+
+//
+// Since the operations are done lazily at {@link #getText}-time, operations do
+// not screw up the token index values. That is, an insert operation at token
+// index {@code i} does not change the index values for tokens
+// {@code i}+1..n-1.
+
+//
+// Because operations never actually alter the buffer, you may always get the
+// original token stream back without undoing anything. Since the instructions
+// are queued up, you can easily simulate transactions and roll back any changes
+// if there is an error just by removing instructions. For example,
+
+//
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+//
+
+//
+// Then in the rules, you can execute (assuming rewriter is visible):
+
+//
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+//
+
+//
+// You can also have multiple "instruction streams" and get multiple rewrites
+// from a single pass over the input. Just name the instruction streams and use
+// that name again when printing the buffer. This could be useful for generating
+// a C file and also its header file--all from the same buffer:
+
+//
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+//
+
+//

+// D.i-j.u D.x-y.v | boundaries overlap combine to max(min)..max(right)
+//
+// I.i.u R.x-y.v | i in (x+1)-y delete I (since insert before
+// we're not deleting i)
+// I.i.u R.x-y.v | i not in (x+1)-y leave alone, non-overlapping
+// R.x-y.v I.i.u | i in x-y ERROR

+// R.x-y.v I.i.u | i not in x-y leave alone, non-overlapping
+//
+// I.i.u = insert u before op @ index i
+// R.x-y.u = replace x-y indexed tokens with u
+//
+// First we need to examine replaces. For any replace op:
+//
+// 1. wipe out any insertions before op within that range.
+// 2. Drop any replace op before that is contained completely within
+// that range.
+// 3. Throw exception upon boundary overlap with any previous replace.
+//
+// Then we can deal with inserts:
+//
+// 1. for any inserts to same index, combine even if not adjacent.
+// 2. for any prior replace with same left boundary, combine this
+// insert with replace and delete this 'replace'.
+// 3. throw exception if index in same range as previous replace
+//
+// Don't actually delete; make op null in list. Easier to walk list.
+// Later we can throw as we add to index → op map.
+//
+// Note that I.2 R.2-2 will wipe out I.2 even though, technically, the
+// inserted stuff would be before the 'replace' range. But, if you
+// add tokens in front of a method body '{' and then delete the method
+// body, I think the stuff before the '{' you added should disappear too.
+//
+// The func returns a map from token index to operation.

+
+A package of validators and sanitizers for strings, structs and collections. Based on [validator.js](https://github.com/chriso/validator.js).
+
+#### Installation
+Make sure that Go is installed on your computer.
+Type the following command in your terminal:
+
+ go get github.com/asaskevich/govalidator
+
+or you can get specified release of the package with `gopkg.in`:
+
+ go get gopkg.in/asaskevich/govalidator.v10
+
+After it the package is ready to use.
+
+
+#### Import package in your project
+Add following line in your `*.go` file:
+```go
+import "github.com/asaskevich/govalidator"
+```
+If you are unhappy to use long `govalidator`, you can do something like this:
+```go
+import (
+ valid "github.com/asaskevich/govalidator"
+)
+```
+
+#### Activate behavior to require all fields have a validation tag by default
+`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
+
+`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
+
+```go
+import "github.com/asaskevich/govalidator"
+
+func init() {
+ govalidator.SetFieldsRequiredByDefault(true)
+}
+```
+
+Here's some code to explain it:
+```go
+// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
+type exampleStruct struct {
+ Name string ``
+ Email string `valid:"email"`
+}
+
+// this, however, will only fail when Email is empty or an invalid email address:
+type exampleStruct2 struct {
+ Name string `valid:"-"`
+ Email string `valid:"email"`
+}
+
+// lastly, this will only fail when Email is an invalid email address but not when it's empty:
+type exampleStruct2 struct {
+ Name string `valid:"-"`
+ Email string `valid:"email,optional"`
+}
+```
+
+#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
+##### Custom validator function signature
+A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible.
+```go
+import "github.com/asaskevich/govalidator"
+
+// old signature
+func(i interface{}) bool
+
+// new signature
+func(i interface{}, o interface{}) bool
+```
+
+##### Adding a custom validator
+This was changed to prevent data races when accessing custom validators.
+```go
+import "github.com/asaskevich/govalidator"
+
+// before
+govalidator.CustomTypeTagMap["customByteArrayValidator"] = func(i interface{}, o interface{}) bool {
+ // ...
+}
+
+// after
+govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, o interface{}) bool {
+ // ...
+})
+```

+```
+
+#### Examples
+###### IsURL
+```go
+println(govalidator.IsURL(`http://user@pass:domain.com/path/page`))
+```
+###### IsType
+```go
+println(govalidator.IsType("Bob", "string"))
+println(govalidator.IsType(1, "int"))
+i := 1
+println(govalidator.IsType(&i, "*int"))
+```
+
+IsType can be used through the tag `type` which is essential for map validation:
+```go
+type User struct {
+ Name string `valid:"type(string)"`
+ Age int `valid:"type(int)"`
+ Meta interface{} `valid:"type(string)"`
+}
+result, err := govalidator.ValidateStruct(User{"Bob", 20, "meta"})
+if err != nil {
+ println("error: " + err.Error())
+}
+println(result)
+```
+###### ToString
+```go
+type User struct {
+ FirstName string
+ LastName string
+}
+
+str := govalidator.ToString(&User{"John", "Juan"})
+println(str)
+```
+###### Each, Map, Filter, Count for slices
+Each iterates over the slice/array and calls Iterator for every item
+```go
+data := []interface{}{1, 2, 3, 4, 5}
+var fn govalidator.Iterator = func(value interface{}, index int) {
+ println(value.(int))
+}
+govalidator.Each(data, fn)
+```
+```go
+data := []interface{}{1, 2, 3, 4, 5}
+var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
+ return value.(int) * 3
+}
+_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
+```
+```go
+data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
+var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
+ return value.(int)%2 == 0
+}
+_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
+_ = govalidator.Count(data, fn) // result = 5
+```
+###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
+If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
+```go
+govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
+ return str == "duck"
+})
+```
+For completely custom validators (interface-based), see below.
+

+Validators with parameters
+
+```go
+"range(min|max)": Range,
+"length(min|max)": ByteLength,
+"runelength(min|max)": RuneLength,
+"stringlength(min|max)": StringLength,
+"matches(pattern)": StringMatches,
+"in(string1|string2|...|stringN)": IsIn,
+"rsapub(keylength)" : IsRsaPub,
+"minstringlength(int): MinStringLength,
+"maxstringlength(int): MaxStringLength,
+```
+Validators with parameters for any type
+
+```go
+"type(type)": IsType,
+```
+
+And here is small example of usage:
+```go
+type Post struct {
+ Title string `valid:"alphanum,required"`
+ Message string `valid:"duck,ascii"`
+ Message2 string `valid:"animal(dog)"`
+ AuthorIP string `valid:"ipv4"`
+ Date string `valid:"-"`
+}
+post := &Post{
+ Title: "My Example Post",
+ Message: "duck",
+ Message2: "dog",
+ AuthorIP: "123.234.54.3",
+}
+
+// Add your own struct validation tags
+govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
+ return str == "duck"
+})
+
+// Add your own struct validation tags with parameter
+govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool {
+ species := params[0]
+ return str == species
+})
+govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$")
+
+result, err := govalidator.ValidateStruct(post)
+if err != nil {
+ println("error: " + err.Error())
+}
+println(result)
+```
+###### ValidateMap [#2](https://github.com/asaskevich/govalidator/pull/338)
+If you want to validate maps, you can use the map to be validated and a validation map that contain the same tags used in ValidateStruct, both maps have to be in the form `map[string]interface{}`
+
+So here is small example of usage:
+```go
+var mapTemplate = map[string]interface{}{
+ "name":"required,alpha",
+ "family":"required,alpha",
+ "email":"required,email",
+ "cell-phone":"numeric",
+ "address":map[string]interface{}{
+ "line1":"required,alphanum",
+ "line2":"alphanum",
+ "postal-code":"numeric",
+ },
+}
+
+var inputMap = map[string]interface{}{
+ "name":"Bob",
+ "family":"Smith",
+ "email":"foo@bar.baz",
+ "address":map[string]interface{}{
+ "line1":"",
+ "line2":"",
+ "postal-code":"",
+ },
+}
+
+result, err := govalidator.ValidateMap(inputMap, mapTemplate)
+if err != nil {
+ println("error: " + err.Error())
+}
+println(result)
+```
+
+###### WhiteList
+```go
+// Remove all characters from string ignoring characters between "a" and "z"
+println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
+```
+
+###### Custom validation functions
+Custom validation using your own domain specific validators is also available - here's an example of how to use it:
+```go
+import "github.com/asaskevich/govalidator"
+
+type CustomByteArray [6]byte // custom types are supported and can be validated
+
+type StructWithCustomByteArray struct {
+ ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
+ Email string `valid:"email"`
+ CustomMinLength int `valid:"-"`
+}
+
+govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, context interface{}) bool {
+ switch v := context.(type) { // you can type switch on the context interface being validated
+ case StructWithCustomByteArray:
+ // you can check and validate against some other field in the context,
+ // return early or not validate against the context at all – your choice
+ case SomeOtherType:
+ // ...
+ default:
+ // expecting some other type? Throw/panic here or continue
+ }
+
+ switch v := i.(type) { // type switch on the struct field being validated
+ case CustomByteArray:
+ for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
+ if e != 0 {
+ return true
+ }
+ }
+ }
+ return false
+})
+govalidator.CustomTypeTagMap.Set("customMinLengthValidator", func(i interface{}, context interface{}) bool {
+ switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
+ case StructWithCustomByteArray:
+ return len(v.ID) >= v.CustomMinLength
+ }
+ return false
+})
+```
+
+###### Loop over Error()
+By default .Error() returns all errors in a single String. To access each error you can do this:
+```go
+ if err != nil {
+ errs := err.(govalidator.Errors).Errors()
+ for _, e := range errs {
+ fmt.Println(e.Error())
+ }
+ }
+```
+
+###### Custom error messages
+Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
+```go
+type Ticket struct {
+ Id int64 `json:"id"`
+ FirstName string `json:"firstname" valid:"required~First name is blank"`
+}
+```

+#### Support
+If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
+
+#### What to contribute
+If you don't know what to do, there are some features and functions that need to be done
+
+- [ ] Refactor code
+- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
+- [ ] Create actual list of contributors and projects that currently using this package
+- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
+- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
+- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
+- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc
+- [x] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224)
+- [ ] Implement fuzzing testing
+- [ ] Implement some struct/map/array utilities
+- [ ] Implement map/array validation
+- [ ] Implement benchmarking
+- [ ] Implement batch of examples
+- [ ] Look at forks for new features and fixes
+
+#### Advice
+Feel free to create what you want, but keep in mind when you implement new features:
+- Code must be clear and readable, names of variables/constants clearly describes what they are doing
+- Public functions must be documented and described in source file and added to README.md to the list of available functions
+- There are must be unit-tests for any new functions and improvements
