 # `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"
+    }
+```

+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`

-## Functions
-
-### Date Functions
-
-- date: Format a date, where a date is an integer type or a time.Time type, and
-  format is a time.Format formatting string.
-- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
-parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
-- now: Current time.Time, for feeding into date-related functions.
-- htmlDate: Format a date for use in the value field of an HTML "date" form element.
-- dateInZone: Like date, but takes three arguments: format, timestamp,
-  timezone.
-- htmlDateInZone: Like htmlDate, but takes two arguments: timestamp,
-  timezone.
-
-### String Functions
-
-- trim: strings.TrimSpace
-- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
-- trimSuffix: strings.TrimSuffix, but with the argument order reversed `trimSuffix "-" "5-"`
-- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
-- upper: strings.ToUpper
-- lower: strings.ToLower
-- title: strings.Title
-- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
-- substr: Given string, start, and length, return a substr.
-- nospace: Remove all spaces from a string. `h e l l o` becomes
-  `hello`.
-- abbrev: Truncate a string with ellipses
-- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
-- abbrevboth: Truncate both sides of a string with ellipses
-- untitle: Remove title case
-- intials: Given multiple words, return the first letter of each
-  word
-- randAlphaNum: Generate a random alpha-numeric string
-- randAlpha: Generate a random alphabetic string
-- randAscii: Generate a random ASCII string, including symbols
-- randNumeric: Generate a random numeric string
-- wrap: Wrap text at the given column count
-- wrapWith: Wrap text at the given column count, and with the given
-  string for a line terminator: `wrap 50 "\n\t" $string`
-- contains: strings.Contains, but with the arguments switched: `contains "cat" "uncatch"`. (This simplifies common pipelines)
-- hasPrefix: strings.hasPrefix, but with the arguments switched: `hasPrefix "cat" "catch"`.
-- hasSuffix: strings.hasSuffix, but with the arguments switched: `hasSuffix "cat" "ducat"`.
-- quote: Wrap strings in double quotes. `quote "a" "b"` returns `"a"
-  "b"`
-- squote: Wrap strings in single quotes.
-- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
-- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces "    foo\n    bar"
-- replace: Replace an old with a new in a string: `$name | replace " " "-"`
-- plural: Choose singular or plural based on length: `len $fish | plural
-  "one anchovy" "many anchovies"`
-- uuidv4: Generate a UUID v4 string
-- sha256sum: Generate a hex encoded sha256 hash of the input
-
-### String Slice Functions:
-
-- join: strings.Join, but as `join SEP SLICE`
-- split: strings.Split, but as `split SEP STRING`. The results are returned
-  as a map with the indexes set to _N, where N is an integer starting from 0.
-  Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
-
-### Integer Slice Functions:
-
-- until: Given an integer, returns a slice of counting integers from 0 to one
-	  less than the given integer: `range $i, $e := until 5`
-- untilStep: Given start, stop, and step, return an integer slice starting at
-	  'start', stopping at `stop`, and incrementing by 'step'. This is the same
-	  as Python's long-form of 'range'.
-
-### Conversions:
-
-- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
-- int: Convert a string or numeric to an int
-- int64: Convert a string or numeric to an int64
-- float64: Convert a string or numeric to a float64
-
-### Defaults:
-
-- default: Give a default value. Used like this: {{trim "   "| default "empty"}}.
-  Since trim produces an empty string, the default value is returned. For
-  things with a length (strings, slices, maps), len(0) will trigger the default.
-  For numbers, the value 0 will trigger the default. For booleans, false will
-  trigger the default. For structs, the default is never returned (there is
-  no clear empty condition). For everything else, nil value triggers a default.
-- empty: Returns true if the given value is the zero value for that
-  type. Structs are always non-empty.
-
-### OS:
-
-- env: Read an environment variable.
-- expandenv: Expand all environment variables in a string.
-
-### Encoding:
-
-- b32enc: Encode a string into a Base32 string
-- b32dec: Decode a string from a Base32 string
-- b64enc: Encode a string into a Base64 string
-- b64dec: Decode a string from a Base64 string
-
-### Data Structures:
-
-- tuple: A sequence of related objects. It is implemented as a
-  `[]interface{}`, where each item can be accessed using `index`.
-- dict: Takes a list of name/values and returns a map[string]interface{}.
-  The first parameter is converted to a string and stored as a key, the
-  second parameter is treated as the value. And so on, with odds as keys and
-  evens as values. If the function call ends with an odd, the last key will
-  be assigned the empty string. Non-string keys are converted to strings as
-  follows: []byte are converted, fmt.Stringers will have String() called.
-  errors will have Error() called. All others will be passed through
-  fmt.Sprtinf("%v").
-- set: Takes a dict, a key, and a value, and sets that key/value pair in
-  the dict. `set $dict $key $value`. For convenience, it returns the dict,
-  even though the dict was modified in place.
-- unset: Takes a dict and a key, and deletes that key/value pair from the
-  dict. `unset $dict $key`. This returns the dict for convenience.
-- hasKey: Takes a dict and a key, and returns boolean true if the key is in
-  the dict.
-
-```
-{{$t := tuple 1 "a" "foo"}}
-{{index $t 2}}{{index $t 0 }}{{index $t 1}}
-{{/* Prints foo1a *}}
-```
-
-### Reflection:
-
-- typeOf: Takes an interface and returns a string representation of the type.
-  For pointers, this will return a type prefixed with an asterisk(`*`). So
-  a pointer to type `Foo` will be `*Foo`.
-- typeIs: Compares an interface with a string name, and returns true if they match.
-  Note that a pointer will not match a reference. For example `*Foo` will not
-  match `Foo`.
-- typeIsLike: returns true if the interface is of the given type, or
-  is a pointer to the given type.
-- kindOf: Takes an interface and returns a string representation of its kind.
-- kindIs: Returns true if the given string matches the kind of the given interface.
-
-	Note: None of these can test whether or not something implements a given
-	interface, since doing so would require compiling the interface in ahead of
-	time.
-
-
-### Math Functions:
-
-Integer functions will convert integers of any width to `int64`. If a
-string is passed in, functions will attempt to conver with
-`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
-
-- add1: Increment an integer by 1
-- add: Sum integers. `add 1 2 3` renders `6`
-- sub: Subtract the second integer from the first
-- div: Divide the first integer by the second
-- mod: Module of first integer divided by second
-- mul: Multiply integers integers
-- max (biggest): Return the biggest of a series of integers. `max 1 2 3`
-  returns `3`.
-- min: Return the smallest of a series of integers. `min 1 2 3` returns
-  `1`.
