The goal of HCL is to build a structured configuration language +that is both human and machine friendly for use with command-line tools, but +specifically targeted towards DevOps tools, servers, etc. + +HCL is also fully JSON compatible. That is, JSON can be used as completely +valid input to a system expecting HCL. This helps makes systems +interoperable with other systems. + +HCL is heavily inspired by +[libucl](https://github.com/vstakhov/libucl), +nginx configuration, and others similar. + +## Why? + +A common question when viewing HCL is to ask the question: why not +JSON, YAML, etc.? + +Prior to HCL, the tools we built at [HashiCorp](http://www.hashicorp.com) +used a variety of configuration languages from full programming languages +such as Ruby to complete data structure languages such as JSON. What we +learned is that some people wanted human-friendly configuration languages +and some people wanted machine-friendly languages. + +JSON fits a nice balance in this, but is fairly verbose and most +importantly doesn't support comments. With YAML, we found that beginners +had a really hard time determining what the actual structure was, and +ended up guessing more than not whether to use a hyphen, colon, etc. +in order to represent some configuration key. + +Full programming languages such as Ruby enable complex behavior +a configuration language shouldn't usually allow, and also forces +people to learn some set of Ruby. + +Because of this, we decided to create our own configuration language +that is JSON-compatible. Our configuration language (HCL) is designed +to be written and modified by humans. The API for HCL allows JSON +as an input so that it is also machine-friendly (machines can generate +JSON instead of trying to generate HCL). + +Our goal with HCL is not to alienate other configuration languages. +It is instead to provide HCL as a specialized language for our tools, +and JSON as the interoperability layer. + +## Syntax + +For a complete grammar, please see the parser itself. A high-level overview +of the syntax and grammar is listed here. + + * Single line comments start with `#` or `//` + + * Multi-line comments are wrapped in `/*` and `*/`. Nested block comments + are not allowed. A multi-line comment (also known as a block comment) + terminates at the first `*/` found. + + * Values are assigned with the syntax `key = value` (whitespace doesn't + matter). The value can be any primitive: a string, number, boolean, + object, or list. + + * Strings are double-quoted and can contain any UTF-8 characters. + Example: `"Hello, World"` + + * Numbers are assumed to be base 10. If you prefix a number with 0x, + it is treated as a hexadecimal. If it is prefixed with 0, it is + treated as an octal. Numbers can be in scientific notation: "1e10". + + * Boolean values: `true`, `false` + + * Arrays can be made by wrapping it in `[]`. Example: + `["foo", "bar", 42]`. Arrays can contain primitives + and other arrays, but cannot contain objects.

+### Contributor License Agreement + +fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/go-fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/go-fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). + +Please indicate that you have signed the CLA in your pull request. + +### How fsnotify is Developed + +* Development is done on feature branches. +* Tests are run on BSD, Linux, OS X and Windows. +* Pull requests are reviewed and [applied to master][am] using [hub][]. + * Maintainers may modify or squash commits rather than asking contributors to. +* To issue a new release, the maintainers will: + * Update the CHANGELOG + * Tag a version, which will become available through gopkg.in. + +### How to Fork + +For smooth sailing, always use the original import path. Installing with `go get` makes this easy. + +1. Install from GitHub (`go get -u github.com/go-fsnotify/fsnotify`) +2. Create your feature branch (`git checkout -b my-new-feature`) +3. Ensure everything works and the tests pass (see below) +4. Commit your changes (`git commit -am 'Add some feature'`) + +Contribute upstream: + +1. Fork fsnotify on GitHub +2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) +3. Push to the branch (`git push fork my-new-feature`) +4. Create a new Pull Request on GitHub + +This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/). + +### Testing + +fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. + +Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. + +To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. + +* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) +* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. +* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) +* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd go-fsnotify/fsnotify; go test'`. +* When you're done, you will want to halt or destroy the Vagrant boxes. + +Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. + +Right now there is no equivalent solution for Windows and OS X, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). + +### Maintainers + +Help maintaining fsnotify is welcome. To be a maintainer: + +* Submit a pull request and sign the CLA as above. +* You must be able to run the test suite on Mac, Windows, Linux and BSD. + +To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. + +All code changes should be internal pull requests. + +Releases are tagged using [Semantic Versioning](http://semver.org/). + +[hub]: https://github.com/github/hub +[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs diff --git a/Godeps/_workspace/src/gopkg.in/fsnotify.v1/LICENSE b/Godeps/_workspace/src/gopkg.in/fsnotify.v1/LICENSE new file mode 100644 index 00000000..f21e5408 --- /dev/null +++ b/Godeps/_workspace/src/gopkg.in/fsnotify.v1/LICENSE @@ -0,0 +1,28 @@ +Copyright (c) 2012 The Go Authors.
