# ResgenSwift

ResgenSwift is a package, fully written in Swift, to help you automatize ressource update and generation.

> 🧐 For all commands, see samples files in `SampleFiles`

## Fonts

Font generator generates an extension of `UIFont` and `Font` (or custom classes). It also prints content of `UIAppFonts` from your project `.plist`. If project `.plist` is specified, it will update `UIAppFonts` content of all `.plist`.

iOS required to use the **real name** of the font, this name can be different from its filename. To get the **real name**, it uses `fc-scan`. So, be sure that the `$PATH` contains path of `fc-scan`.

**Example**

```sh
swift run -c release ResgenSwift fonts $FORCE_FLAG "./Fonts/fonts.txt" \
 --extension-output-path "./Fonts/Generated" \
 --extension-name "AppFont" \
 --extension-name-swift-ui "SUIAppFont" \
 --extension-suffix "GreatApp" \
 --static-members true \
 --info-plist-paths "./path/one/to/Info.plist ./path/two/to/Info.plist"
```

**Parameters**

1. `-f`: force generation
2. Font input folder, it will search for every `.ttf` and `.otf` files specified in `fonts.txt`
3. `--extension-output-path`: path where to generate generated extension
4. `--extension-name` *(optional)* : name of the class to add UIKit getters
5. `--extension-name-swift-ui` *(optional)* : name of the class to add SwiftUI getters
6. `--extension-suffix` *(optional)* : additional text which is added to the filename (ex: `AppFont+GreatApp.swift`)
7. `--static-members` *(optional)*: generate static properties or not
8. `--info-plist-paths` *(optional)*: array of `.plist`, you can specify multiple `Info.plist` for multiple targets


## Colors

Colors generator generates an extension of `UIColor` (or a custom class) along with colorsets in specified xcassets.

```sh
swift run -c release ResgenSwift colors $FORCE_FLAG "./Colors/colors.txt" \
 --style all \
 --xcassets-path "./Colors/colors.xcassets" \
 --extension-output-path "./Colors/Generated/" \
 --extension-name "AppColor" \
 --extension-name-swift-ui "SUIAppColor" \ 
 --extension-suffix "GreatApp" \
 --static-members true
```

**Parameters**

1. `-f`: force generation
2. Input colors file
3. `--style` can be `all` or `light`
4. `--extension-output-path`: path where to generate generated extension
5. `--extension-name` *(optional)* : name of the class to add UIKit getters
6. `--extension-name-swift-ui` *(optional)* : name of the class to add SwiftUI getters
7. `--extension-suffix` *(optional)* : additional text which is added to filename (ex: `AppColor+GreatApp.swift`)
8. `--static-members` *(optional)*: generate static properties or not
   
 
## Strings

Strings command allows to generate `strings` files along with extensions to access those strings easily. It can do it 2 ways: Twine and Stringium. It is not recommended to use Twine except on legacy projects or while migrating to ResgenSwift, because it use https://github.com/openium/twine. Using Stringium is recommended because it does not required external dependency and allow more customisation.

### Twine (not recommended)

```sh
swift run -c release ResgenSwift strings twine $FORCE_FLAG "./Twine/strings.txt" \
 --output-path "./Twine/Generated" \
 --langs "fr en en-us" \
 --default-lang "en" \
 --extension-output-path "./Twine/Generated"
```
 
 **Parameters**

1. `-f`: force generation
2. Input translations file (must be Twine formatted)
3. `--langs`: langs to generate (string with space between each lang)
4. `--default-lang`: default lang that will be in `Base.lproj`. It must be in `langs` as well
4. `--extension-output-path`: path where to generate generated extension

### Stringium (recommended)

```sh
swift run -c release ResgenSwift strings stringium $FORCE_FLAG "./Strings/strings.txt" \
 --output-path "./Strings/Generated" \
 --langs "fr en en-us" \
 --default-lang "en" \
 --extension-output-path "./Strings/Generated" \
 --extension-name "AppString" \
 --extension-suffix "GreatApp" \
 --static-members true
```

 **Parameters**

1. `-f`: force generation
2. Input translations file (must be Twine formatted)
3. `--langs`: langs to generate (string with space between each lang)
4. `--default-lang`: default lang that will be in `Base.lproj`. It must be in `langs` as well
4. `--extension-output-path`: path where to generate generated extension
5. `--extension-name` *(optional)* : name of class to add the extension
6. `--extension-suffix` *(optional)* : additional text which is added to filename (ex: `AppString+GreatApp.swift`)
7. `--static-members` *(optional)*: generate static properties or not


## Tags

Tags is also a subcommand of `Strings`. Input files are formatted the same way. Tags will generate properties which return exactly what is specified in the input file. It was designed to be used for analytics purpose and to be shared with any other platform to have the same analytics keys.

```sh
swift run -c release ResgenSwift strings tags $FORCE_FLAG "./Tags/tags.txt" \
 --lang "ium" \
 --extension-output-path "./Tags/Generated" \
 --extension-name "AppTags" \
 --extension-suffix "GreatApp" \
 --static-members true
```

 **Parameters**

1. `-f`: force generation
2. Input tags file (must be Twine formatted)
3. `--lang`: langs to look at in input file
4. `--extension-output-path`: path where to generate generated extension
5. `--extension-name` *(optional)* : name of class to add the extension
6. `--extension-suffix` *(optional)* : additional text which is added to filename (ex: `AppTags+GreatApp.swift`)
7. `--static-members` *(optional)*: generate static properties or not

> ⚠️ If extension name is not set or is `Tags`, it will generate the following typaloas  `typealias Tags = String`.

## Images

Images generator will generate images assets along with extensions to access those images easily.

```sh
swift run -c release ResgenSwift images $FORCE_FLAG "./Images/images.txt" \
 --xcassets-path "./Images/app.xcassets" \
 --extension-output-path "./Images/Generated" \
 --extension-name "AppImage" \
 --extension-name-swift-ui "SUIAppImage" \ 
 --extension-suffix "GreatApp" \
 --static-members true
```

 **Parameters**

1. `-f`: force generation
2. Input images definitions file
3. `--xcassets-path`: xcasset path where to generate imagesets
4. `--extension-output-path`: path where to generate generated extension
5. `--extension-name` *(optional)* : name of the class to add UIKit getters
6. `--extension-name-swift-ui` *(optional)* : name of the class to add SwiftUI getters
6. `--extension-suffix` *(optional)* : additional text which is added to filename (ex: `AppImage+GreatApp.swift`)
7. `--static-members` *(optional)*: generate static properties or not


## All at once

Another command exists to generate all ressources at the same time: `generate`. It use the following commands: `Fonts`, `Colors`, `Strings/Stringium`, `Strings/Tags`, `Images`.

All parameters can be specified in a configuration file in `Yaml`:

> Order of configuration types does not matter. Order them to fit your needs.

```yaml
---
colors:
-
  inputFile: String
  style: [light/all]
  xcassetsPath: String
  extensionOutputPath: String
  extensionName: String?
  extensionNameSwiftUI: String?
  extensionSuffix: String?
  staticMembers: Bool?

fonts:
-
  inputFile: String
  extensionOutputPath: String
  extensionName: String?
  extensionNameSwiftUI: String?
  extensionSuffix: String?
  staticMembers: Bool?
  infoPlistPaths: [String]
  
images:
- 
  inputFile: String
  xcassetsPath: String
  extensionOutputPath: String
  extensionName: String?
  extensionNameSwiftUI: String?
  extensionSuffix: String?
  staticMembers: Bool?

strings:
- 
  inputFile: String
  outputPath: String
  langs: String
  defaultLang: String
  extensionOutputPath: String
  extensionName: String?
  extensionSuffix: String?
  staticMembers: Bool?

tags:
- 
  inputFile: String
  lang: String
  extensionOutputPath: String
  extensionName: String?
  extensionSuffix: String?
  staticMembers: Bool?
```

### Multiple configurations

In some case, you may need to have 2 colors files in your projects. You will need 2 colors configurations. Every configuration type is an array and can contains as many configurations as you need. 

Sample for 2 colors configurations:

```yaml
...
colors:
-
  inputFile: String
  style: [light/all]
  xcassetsPath: String
  extensionOutputPath: String
  extensionName: String?
  extensionNameSwiftUI: String?
  extensionSuffix: String?
  staticMembers: Bool?
-
  inputFile: String
  style: [light/all]
  xcassetsPath: String
  extensionOutputPath: String
  extensionName: String?
  extensionNameSwiftUI: String?
  extensionSuffix: String?
  staticMembers: Bool?  
...
```

### No configuration

In some case, you may not need to generate tags for example. You must specified `tags` as an empty array :

```yaml
...
tags: []
...
```

### Usage

```sh
swift run -c release ResgenSwift generate path/to/configuration.yml --project-directory ${PROJECT_DIR}
```

> ⚠️ Every path in `configuration.yml` will be prepended by content of `--project-directory` if they are relative path (not starting with `/`)


## Installation

Simple run `./install.sh`. Binary will be install in `/usr/local/bin`. Then, use ResgenSwift like any other command:

Example:

```sh
ResgenSwift generate path/to/configuration.yml --project-directory ${PROJECT_DIR}
```
