 # `protoc-gen-gotemplate`
 :open_file_folder: protocol generator + golang text/template (protobuf)
 
-Generic protocol buffer generator backed by Golang's [text/template](https://golang.org/pkg/text/template).
+A generic **code**/script/data generator based on [Protobuf](https://developers.google.com/protocol-buffers/).
 
 ---
 
-This is a generator plugin for the Google Protocol Buffers compiler (`protoc`).
+This project is a generator plugin for the Google Protocol Buffers compiler (`protoc`).
 
-The plugin can generate files based on a template directory using the [Golang's `text/template`](https://golang.org/pkg/text/template/) engine.
+The plugin parses **protobuf** files, generates an **ast**, and walks a local **templates directory** to generate files using the [Golang's `text/template` engine](https://golang.org/pkg/text/template/).
+
+## Philosophy
+
+* protobuf-first
+* no built-in template, only user defined templates
+* kiss, *keep it stupid simple*
+
+## Under the hood
+
+1. the *user* `protobuf` files are parsed by [`protoc`](https://github.com/google/protobuf/releases)
+2. the `ast` is generated by [`protoc-gen-go` helpers](https://github.com/golang/protobuf/tree/master/protoc-gen-go)
+3. the `ast` is given to [Golang's `text/template` engine](https://golang.org/pkg/text/template/) for each *user* template files
+4. the *funcmap* enriching the template engine is based on [Masterminds/sprig](https://github.com/Masterminds/sprig), and contains type-manipulation, iteration and language-specific helpers

 ## Usage
 
 `protoc-gen-gotemplate` requires a **template_dir** directory *(by default `./templates`)*.
 
-Every files ending with `.tmpl` will be processed and written in the destination folder, following the file hierarchy of the `template_dir`, and removing the `.tmpl` extension.

+| `destination_dir`     | `.`           | absolute or relative path | base path to write output
+| `single-package-mode` | *false*       | `true` or `false`         | if *true*, `protoc` won't accept multiple packages to be compiled at once (*!= from `all`*), but will support `Message` lookup across the imported protobuf dependencies
+| `debug`               | *false*       | `true` or `false`         | if *true*, `protoc` will generate a more verbose output
+| `all`                 | *false*       | `true` or `false`         | if *true*, protobuf files without `Service` will also be parsed
+
+##### Hints
+
+Shipping the templates with your project is very smart and useful when contributing on git-based projects.
+
+Another workflow consists in having a dedicated repository for generic templates which is then versioned and vendored with multiple projects (npm package, golang vendor package, ...)

+# 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
+
+[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.png)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/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"
+    }
+```
