+# SemVer
+
+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix
+
+[](https://masterminds.github.io/stability/active.html)
+[](https://travis-ci.org/Masterminds/semver) [](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [](https://godoc.org/github.com/Masterminds/semver) [](https://goreportcard.com/report/github.com/Masterminds/semver)
+
+## Parsing Semantic Versions
+
+To parse a semantic version use the `NewVersion` function. For example,
+
+```go
+ v, err := semver.NewVersion("1.2.3-beta.1+build345")
+```
+
+If there is an error the version wasn't parseable. The version object has methods
+to get the parts of the version, compare it to other versions, convert the
+version back into a string, and get the original string. For more details
+please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
+package from the standard library. For example,
+
+```go
+ raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+ vs := make([]*semver.Version, len(raw))
+ for i, r := range raw {
+ v, err := semver.NewVersion(r)
+ if err != nil {
+ t.Errorf("Error parsing version: %s", err)
+ }
+
+ vs[i] = v
+ }
+
+ sort.Sort(semver.Collection(vs))
+```
+
+## Checking Version Constraints
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+ c, err := semver.NewConstraint(">= 1.2.3")
+ if err != nil {
+ // Handle constraint not being parseable.
+ }
+
+ v, _ := semver.NewVersion("1.3")
+ if err != nil {
+ // Handle version not being parseable.
+ }
+ // Check if the version meets the constraints. The a variable will be true.
+ a := c.Check(v)
+```
+
+## Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma separated and comparisons. These are then separated by || separated or
+comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+* `=`: equal (aliased to no operator)
+* `!=`: not equal
+* `>`: greater than
+* `<`: less than
+* `>=`: greater than or equal to
+* `<=`: less than or equal to
+
+_Note, according to the Semantic Version specification pre-releases may not be
+API compliant with their release counterpart. It says,_
+
+> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._
+
+_SemVer comparisons without a pre-release value will skip pre-release versions.
+For example, `>1.2.3` will skip pre-releases when looking at a list of values
+while `>1.2.3-alpha.1` will evaluate pre-releases._
+
+## Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
+
+## Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the pack level comparison (see tilde below). For example,
+
+* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `>= 1.2.x` is equivalent to `>= 1.2.0`
+* `<= 2.x` is equivalent to `<= 3`
+* `*` is equivalent to `>= 0.0.0`
+
+## Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+* `~1` is equivalent to `>= 1, < 2`
+* `~2.3` is equivalent to `>= 2.3, < 2.4`
+* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `~1.x` is equivalent to `>= 1, < 2`
+
+## Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes. This is useful
+when comparisons of API versions as a major change is API breaking. For example,
+
+* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+* `^2.3` is equivalent to `>= 2.3, < 3`
+* `^2.x` is equivalent to `>= 2.0.0, < 3`
+
+# Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+ c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+ if err != nil {
+ // Handle constraint not being parseable.
+ }
+
+ v, _ := semver.NewVersion("1.3")
+ if err != nil {
+ // Handle version not being parseable.
+ }
+
+ // Validate a version against a constraint.
+ a, msgs := c.Validate(v)
+ // a is false
+ for _, m := range msgs {
+ fmt.Println(m)
+
+ // Loops over the errors which would read
+ // "1.3 is greater than 1.2.3"
+ // "1.3 is less than 1.4"
+ }
+```

+/*
+Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
+
+Specifically it provides the ability to:
+
+ * Parse semantic versions
+ * Sort semantic versions
+ * Check if a semantic version fits within a set of constraints
+ * Optionally work with a `v` prefix
+
+Parsing Semantic Versions
+
+To parse a semantic version use the `NewVersion` function. For example,
+
+ v, err := semver.NewVersion("1.2.3-beta.1+build345")
+
+If there is an error the version wasn't parseable. The version object has methods
+to get the parts of the version, compare it to other versions, convert the
+version back into a string, and get the original string. For more details
+please see the documentation at https://godoc.org/github.com/Masterminds/semver.
+
+Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+ raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+ vs := make([]*semver.Version, len(raw))
+ for i, r := range raw {
+ v, err := semver.NewVersion(r)
+ if err != nil {
+ t.Errorf("Error parsing version: %s", err)
+ }
+
+ vs[i] = v
+ }
+
+ sort.Sort(semver.Collection(vs))
+
+Checking Version Constraints
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+ c, err := semver.NewConstraint(">= 1.2.3")
+ if err != nil {
+ // Handle constraint not being parseable.
+ }
+
+ v, _ := semver.NewVersion("1.3")
+ if err != nil {
+ // Handle version not being parseable.
+ }
+ // Check if the version meets the constraints. The a variable will be true.
+ a := c.Check(v)
+
+Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma separated and comparisons. These are then separated by || separated or
+comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+ * `=`: equal (aliased to no operator)
+ * `!=`: not equal
+ * `>`: greater than
+ * `<`: less than
+ * `>=`: greater than or equal to
+ * `<=`: less than or equal to
+
+Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+ * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+ * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
+
+Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the pack level comparison (see tilde below). For example,
+
+ * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+ * `>= 1.2.x` is equivalent to `>= 1.2.0`
+ * `<= 2.x` is equivalent to `<= 3`
+ * `*` is equivalent to `>= 0.0.0`
+
+Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+ * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+ * `~1` is equivalent to `>= 1, < 2`
+ * `~2.3` is equivalent to `>= 2.3, < 2.4`
+ * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+ * `~1.x` is equivalent to `>= 1, < 2`
+
+Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes. This is useful
+when comparisons of API versions as a major change is API breaking. For example,
+
+ * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+ * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+ * `^2.3` is equivalent to `>= 2.3, < 3`
+ * `^2.x` is equivalent to `>= 2.0.0, < 3`

+Package log implements a simple structured logging API designed with few assumptions. Designed for
+centralized logging solutions such as Kinesis which require encoding and decoding before fanning-out
+to handlers.
+
+You may use this package with inline handlers, much like Logrus, however a centralized solution
+is recommended so that apps do not need to be re-deployed to add or remove logging service
+providers.

+# Lifecycle
+
+[](https://travis-ci.org/buildpack/lifecycle)
+[](https://godoc.org/github.com/buildpacks/lifecycle)
+
+A reference implementation of [Buildpack API v3](https://github.com/buildpacks/spec).
+
+## Commands
+
+### Build
+
+* `detector` - chooses buildpacks (via `/bin/detect`)
+* `analyzer` - restores launch layer metadata from the previous build
+* `builder` - executes buildpacks (via `/bin/build`)
+* `exporter` - remotely patches images with new layers (via rebase & append)
+* `launcher` - invokes choice of process
+
+### Develop
+
+* `detector` - chooses buildpacks (via `/bin/detect`)
+* `developer` - executes buildpacks (via `/bin/develop`)
+* `launcher` - invokes choice of process
+
+### Cache
+
+* `restorer` - restores cache
+* `cacher` - updates cache
+
+### Rebase
+
+* `rebaser` - remotely patches images with new base image
+
+## Notes
+
+Cache implementations (`restorer` and `cacher`) are intended to be interchangeable and platform-specific.
+A platform may choose not to deduplicate cache layers.
+
+## Development
+To test, build, and package binaries into an archive, simply run:
+
+```bash
+$ make all
+```
+This will create an archive at `out/lifecycle-+linux.x86-64.tgz`.
+
+By default, `LIFECYCLE_VERSION` is `0.0.0`. It can be changed by prepending `LIFECYCLE_VERSION=` to the
+`make` command. For example:
+
+```bash
+$ LIFECYCLE_VERSION=1.2.3 make all
+```
+
+Steps can also be run individually as shown below.
+
+### Test
+
+Formats, vets, and tests the code.
+
+```bash
+$ make test
+```
+
+### Build
+
+Builds binaries to `out/lifecycle/`.
+
+```bash
+$ make build
+```
+
+> To clean the `out/` directory, run `make clean`.
+
+### Package
+
+Creates an archive at `out/lifecycle-+linux.x86-64.tgz`, using the contents of the
+`out/lifecycle/` directory, for the given (or default) `LIFECYCLE_VERSION`.
+
+```bash
+$ make package
+```

+We're glad you are interested in contributing to this project. We hope that this
+document helps you get started.
+
+If something is missing, incorrect, or made irrelevant please feel free to make
+a PR to keep it up-to-date.
+
+## Prerequisites
+
+- [Go](https://golang.org/dl/)
+ - including [Git](https://git-scm.com/)
+- [Docker](https://www.docker.com/)
+
+## Development
+
+### Building
+
+To build pack:
+```
+make build
+```
+
+This will output the binary to the directory `out/`.
+
+Options:
+
+| ENV_VAR | Description | Default |
+|--------------|------------------------------------------------------------------------|---------|
+| GOCMD | Change the `go` executable. For example, [richgo][rgo] for testing. | go |
+| PACK_BIN | Change the name or location of the binary relative to `out/`. | pack |
+| PACK_VERSION | Tell `pack` what version to consider itself | `dev` |
+
+[rgo]: https://github.com/kyoh86/richgo
+
+_NOTE: This project uses [go modules](https://github.com/golang/go/wiki/Modules) for dependency management._
+
+### Testing
+
+To run unit and integration tests:
+
+```bash
+make unit
+```
+
+To run acceptance tests:
+```bash
+make acceptance
+```
+
+Alternately, to run all tests:
+```bash
+make test
+```
+
+### Formatting
+
+To format the code:
+
+```bash
+make format
+```
+
+### Verification
+
+To verify formatting and vet:
+```bash
+make verify
+```
+
+## Pull Requests
+
+1. **[Fork]((https://help.github.com/en/articles/fork-a-repo)) the repo**
+2. **Code, Test, Commit...**
+
+ _Don't forget utilize the convenient make functions above._
+
+3. **Preparing a Branch**
+
+ We prefer to have PRs that are encompassed in a single commit. This might
+ require that you execute some of these commands:
+
+ If you are no up-to-date with master:
+ ```bash
+ # rebase from master (applies your changes on top of master)
+ git pull -r origin master
+ ```
+
+ If you made more than one commit:
+ ```bash
+ # squash multiple commits, if applicable
+ # set the top most commit to `pick` and all subsequent to `squash`
+ git rebase -i origin/master
+ ```
+
+ Another requirement is that you sign your work. See [DCO](https://probot.github.io/apps/dco/) for more details.
+ ```bash
+ git commit --amend --signoff
+ ```
+
+4. **Submit a Pull Request**
+
+ Submitting the pull request is done in [GitHub](https://github.com/buildpacks/pack/compare/) by selecting
+ your branch as the `compare` branch.

+# Color [](https://godoc.org/github.com/heroku/color) [](https://circleci.com/gh/heroku/color)
+
+Color is based on the [github.com/fatih/color](https://github.com/fatih/color) package. Unfortunately the original
+color package is archived and is no longer supported. Like the original, this package lets you use colorized outputs in
+terms of [ANSI Escape Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Golang but offers a number of
+improvements from the original. Posix and Windows platforms are supported.
+
+Color seeks to remain *mostly* backward compatible with fatih/color but has a number of changes to support concurrency,
+improved performance and a more idiomatic style.
+
+## Changes And Improvements
+
+The methods of the new `Color` struct do not mutate the sender. This
+results in better concurrency support and improved performance.
+
+You don't need to remember to wrap io.Writer arguments in `colorable.NewColorable` in order to support Windows functionality.
+
+Package public global variables are removed. `color.NoColor` was removed and replaced with the `Disable` function.
+ Colored output can be toggled using the `Disable`. `color.Output` and `color.Error`replaced by `Stdout()` and `Stderr()`
+.
+
+Instances of `Console` can be passed to methods in third party packages that take `io.Writer` as an argument. If the
+ third party package emits ANSI color information the passed in writer will be interpreted correctly on Windows. In
+ addition, color information can be stripped for a console by calling `Console.DisableColors(true)`.
+
+Performance is improved significantly, as much as 400%. Note that some functions that you'd expect to take an
+array of interface{} take an array of strings instead because underlying calls to fmt.SprintXX functions are slow.
+
+`fatih/color` has race conditions. This package was developed with `test.Parallel` and `-race` enabled for tests. Thus
+far no race conditions are known and so this package is suitable for use in a multi goroutine environment.
+
+## Examples
+
+### Standard colors
+
+```go
+// Print with default helper functions
+color.Cyan("Prints text in cyan.")
+
+// A newline will be appended automatically
+color.Blue("Prints %s in blue.", "text")
+```
+
+### Mix and reuse colors
+
+```go
+// Create a new color object
+color.Stdout().Println(color.New(color.FgCyan, color.Underline), "Prints cyan text with an underline.")
+```
+
+### Use your own output (io.Writer)
+
+```go
+// Use your own io.Writer output
+wtr := color.NewConsole(os.Stderr)
+wtr.Println(color.New(color.FgBlue), "Hello! I'm blue.")
+```
+
+### Custom print functions (PrintFunc)
+
+```go
+// Create a custom print function for convenience
+red := color.StdErr().PrintfFunc(color.New(color.FgRed))
+red("Warning")
+red("Error: %s", err)
+
+// Mix up multiple attributes
+notice := color.Stdout().PrintlnFunc(color.New(color.Bold, color.FgGreen))
+notice("Don't forget this...")
+```
+### Insert into noncolor strings (SprintFunc)
+
+```go
+// Create SprintXxx functions to mix strings with other non-colorized strings:
+yellow := color.New(color.FgYellow).SprintFunc()
+red := color.New(color.FgRed).SprintFunc()
+fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
+fmt.Printf("This %s rocks!\n", info("package"))
+
+// Use helper functions
+fmt.Println("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
+```
+### Disable/Enable color
+
+There might be a case where you want to explicitly disable/enable color output.
+
+`Color` has support to disable/enable colors on a per `Console` basis.
+For example suppose you have a CLI app and a `--no-color` bool flag. You
+can easily disable the color output with:
+
+```go
+
+var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+color.Stdout().DisableColors(*flagNoColor)
+
+```

+# ioprogress
+
+ioprogress is a Go (golang) library with implementations of `io.Reader`
+and `io.Writer` that draws progress bars. The primary use case for these
+are for CLI applications but alternate progress bar writers can be supplied
+for alternate environments.
+
+## Example
+
+
+
+## Installation
+
+Standard `go get`:
+
+```
+$ go get github.com/mitchellh/ioprogress
+```
+
+## Usage
+
+Here is an example of outputting a basic progress bar to the CLI as
+we're "downloading" from some other `io.Reader` (perhaps from a network
+connection):
+
+```go
+// Imagine this came from some external source, such as a network connection,
+// and that we have the full size of it, such as from a Content-Length HTTP
+// header.
+var r io.Reader
+
+// Create the progress reader
+progressR := &ioprogress.Reader{
+ Reader: r,
+ Size: rSize,
+}
+
+// Copy all of the reader to some local file f. As it copies, the
+// progressR will write progress to the terminal on os.Stdout. This is
+// customizable.
+io.Copy(f, progressR)
+```
