-# protoc-gen-gotemplate
+# `protoc-gen-gotemplate`
 :open_file_folder: protocol generator + golang text/template (protobuf)
+
+A generic **code**/script/data generator based on [Protobuf](https://developers.google.com/protocol-buffers/).
+
+---
+
+This project is a generator plugin for the Google Protocol Buffers compiler (`protoc`).
+
+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
+
+## Web editor
+
+![Web editor screenshot](https://github.com/moul/protoc-gen-gotemplate/raw/master/assets/web-editor.jpg)
+
+[Demo server](http://protoc-gen-gotemplate.m.42.am/)
+
+## Usage
+
+`protoc-gen-gotemplate` requires a **template_dir** directory *(by default `./templates`)*.
+
+Every file ending with `.tmpl` will be processed and written to the destination folder, following the file hierarchy of the `template_dir`, and remove the `.tmpl` extension.
+
+---
+
+```console
+$> ls -R
+input.proto     templates/doc.txt.tmpl      templates/config.json.tmpl
+$> protoc --gotemplate_out=. input.proto
+$> ls -R
+input.proto     templates/doc.txt.tmpl      templates/config.json.tmpl
+doc.txt         config.json
+```
+
+### Options
+
+You can specify custom options, as follow:
+
+```console
+$> protoc --gotemplate_out=debug=true,template_dir=/path/to/template/directory:. input.proto
+```
+
+| Option                | Default Value | Accepted Values           | Description
+|-----------------------|---------------|---------------------------|-----------------------
+| `template_dir`        | `./template`  | absolute or relative path | path to look for templates
+| `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, ...)
+
+See [examples](./examples).
+
+## Funcmap
+
+This project uses [Masterminds/sprig](https://github.com/Masterminds/sprig) library and additional functions to extend the builtin [text/template](https://golang.org/pkg/text/template) helpers.
+
+Non-exhaustive list of new helpers:
+
+* **all the functions from [sprig](https://github.com/Masterminds/sprig)**
+* `add`
+* `boolFieldExtension`
+* `camelCase`
+* `contains`
+* `divide`
+* `fieldMapKeyType`
+* `fieldMapValueType`
+* `first`
+* `getEnumValue`
+* `getMessageType`
+* `getProtoFile`
+* `goNormalize`
+* `goTypeWithPackage`
+* `goType`
+* `goZeroValue`
+* `haskellType`
+* `httpBody`
+* `httpPath`
+* `httpPathsAdditionalBindings`
+* `httpVerb`
+* `index`
+* `int64FieldExtension`
+* `isFieldMap`
+* `isFieldMessageTimeStamp`
+* `isFieldMessage`
+* `isFieldRepeated`
+* `jsSuffixReserved`
+* `jsType`
+* `json`
+* `kebabCase`
+* `last`
+* `leadingComment`
+* `leadingDetachedComments`
+* `lowerCamelCase`
+* `lowerFirst`
+* `lowerGoNormalize`
+* `multiply`
+* `namespacedFlowType`
+* `prettyjson`
+* `replaceDict`
+* `shortType`
+* `snakeCase`
+* `splitArray`
+* `stringFieldExtension`
+* `stringMethodOptionsExtension`
+* `string`
+* `subtract`
+* `trailingComment`
+* `trimstr`
+* `upperFirst`
+* `urlHasVarsFromMessage`
+
+See the project helpers for the complete list.
+
