Samples (Base Template)

Download the sample source and modify the "/Resources/TestCase0?Localizable.strings" file. Then run the build. This will change the file "/Constants/Test.Case0?.Localized.swift".

Case 01 ~ 07 : Test results

ViewController.swift

override func viewDidLoad() {
        super.viewDidLoad()
        
        testSamplesBaseTemplates()
    }

    func testSamplesBaseTemplates() {
        // Case 01 : String
        case01Label.text = L10n.testCase01TitleTop01
        
        // Case 02 : String
        case02Label.text = TestCase02Strings.testCase02TitleTop01
        
        // Case 03 : String
        case03Label.text = TestCase03Strings.testCase03TitleBottom01
        
        // Case 04 : Storyboard
        // Pass
        
        // Case 05-1 : Assets
        //        let swiftGenSample01Image = UIImage(asset: Asset.imageSwiftGenSample01)
        let swiftGenSample01Image = Asset.imageSwiftGenSample01.image
        case0501ImageView.image = swiftGenSample01Image
        debugPrint(Asset.allImages)
        
        //        case0502Label.textColor = UIColor(asset: Asset.test01Color)
        case0502Label.textColor = Asset.test01Color.color
        debugPrint(Asset.allColors)
        
        // Case 06 : Colors
        //        case06Label.textColor = Color(named:ColorName.articleBody)
        case06Label.textColor = ColorName.articleBody.color
        
        // Case 07 : Fonts
        //        case06Label.font = UIFont(font: FontFamily.SFCompactDisplay.ultralight, size: 30.0)
        case07Label.font = UIFont(font: FontFamily.SFProDisplay.blackItalic, size: 30.0)
    }

Let's look at the details.

Case 01 : String

Let's build it!

resource file : TestCase01Localizable.strings

Script..

# testing script case 01
swiftgen strings "${SRCROOT}/${TARGETNAME}/Resources/TestCase01Localizable.strings" --template structured-swift4 --output "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case01.Localized.swift"

Read the Link(SwiftGen) "Templates bundled with SwiftGen:".

A swift2 template, compatible with Swift 2
A swift3 template, compatible with Swift 3
A swift4 template, compatible with Swift 4
Other variants, like flat-swift2/3/4 and structured-swift2/3/4 templates for Strings, etc.

result

file link : .. /Constants/BasicTemplate/Test.Case01.Localized.swift

Case 02 : String

Define the naming of the enum yourself, and abbreviate the command.

add : --param enumName=TestCase02Strings
modify : --output => -o
modify : --template => -t

Script..

# testing script case 02
swiftgen strings --param enumName=TestCase02Strings "${SRCROOT}/${TARGETNAME}/Resources/TestCase02Localizable.strings" -t structured-swift4 -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case02.Localized.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case02.Localized.swift

Case 03 : String

Add localization

modify : ../Resources/.. => ../Resources/Base.lproj/..

difference point

Script.. 

# testing script case 03
swiftgen strings --param enumName=TestCase03Strings "${SRCROOT}/${TARGETNAME}/Resources/Base.lproj/TestCase03Localizable.strings" -t structured-swift4 -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case03.Localized.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case03.Localized.swift

Case 04 : StoryBoard

Storyboards are a little different but similar.

Script.. 

# testing script case 04
swiftgen storyboards -t swift4 "${SRCROOT}/${TARGETNAME}/Base.lproj/Main.storyboard" -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case04.Storyboards.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case04.Storyboards.swift

Case 05 : Xcassets

Let's try Xcassets!

Script.. 

# testing script case 05
swiftgen xcassets "${SRCROOT}/${TARGETNAME}/Assets.xcassets" -t swift4 -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case05.Xcassets.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case05.Xcassets.swift

Case 06 : Colors

I added color samples. However, you can add color in xcassets. It will then be added to the output of case 5.

SwiftGen/SwiftGen#315

add file (colors.txt)

add colors.txt

Script.. 

# testing script case 06
swiftgen colors -t swift4 "${SRCROOT}/${TARGETNAME}/Resources/colors.txt"  -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case06.Colors.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case06.Colors.swift

Case 07 : Fonts

I added some of the font files from Apple, and tried to code-generate the fonts in that path into files.

add fonts file (in "Font" folder)

add fonts file

Script.. 

# testing script case 07
# https://developer.apple.com/fonts/
swiftgen fonts -t swift4 "${SRCROOT}/${TARGETNAME}/Resources/Font"  -o "${SRCROOT}/${TARGETNAME}/Constants/BasicTemplate/Test.Case07.Fonts.swift"

result

file link : .. /Constants/BasicTemplate/Test.Case07.Fonts.swift

Samples (User Custom, Use of Stencil)

Let's create a file that you want to make.

What is Stencil? : https://stencil.fuller.li/en/latest/

The Stencil template language

Stencil is a simple and powerful template language for Swift. 
It provides a syntax similar to Django and Mustache. 
If you’re familiar with these, 
you will feel right at home with Stencil.

You only need to know how to use it, and you can use Stencil by default.
Take a look at the use cases below.

How do I customize it?

If you know the grammar, how can you customize it? That way, you can click the link below to get the template source. This can be analyzed and corrected.

https://github.com/SwiftGen/SwiftGen/tree/master/templates

Case 01 : String, Objective-C?

What if you want to make it an Objective-C source? Let's try it.

I tried to make it #define simply. :)

Script.. 

# testing script case 01
swiftgen strings "${SRCROOT}/${TARGETNAME}/Resources/TestCase01Localizable.strings" --templatePath ${SRCROOT}/swiftgen/StencilTemplates/Localization/objLocalization.stencil --output "${SRCROOT}/${TARGETNAME}/Constants/CustomTemplate/Test.Custom.Case01.Localized.h"

objLocalization.stencil

{% if tables.count > 0 %}

{# You can modify the value below with the actual value. #}
{% macro recursiveBlock table item sp %}
{{sp}}  {% for string in item.strings %}
{{sp}}  {% if not param.noComments %}
{{sp}}  /// {{string.translation}}
{{sp}}  #define {{string.name}} "{{string.key}}"
{{sp}}  {% endif %}
{{sp}}  {% if not param.noComments %}
{{sp}}  /// LOG : {{string}}
{{sp}}  {% endif %}
{{sp}}  {% endfor %}
{% endmacro %}

{# print #}
{% call recursiveBlock tables.first.name tables.first.levels "" %}

{% else %}
// No string found
{% endif %}

result

file link : .. /Constants/CustomTemplate/Test.Custom.Case01.Localized.h

  /// test(case01) string 1
  #define test_case01_sub_index01 "test_case01_sub_index01"
  /// LOG : ["translation": "test(case01) string 1", "name": "test_case01_sub_index01", "key": "test_case01_sub_index01"]
  /// test(case01) string 2
  #define test_case01_sub_index02 "test_case01_sub_index02"
  /// LOG : ["translation": "test(case01) string 2", "name": "test_case01_sub_index02", "key": "test_case01_sub_index02"]
  /// test(case01) sample 2
  #define test_case01_title_bottom01 "test_case01_title_bottom01"
  /// LOG : ["translation": "test(case01) sample 2", "name": "test_case01_title_bottom01", "key": "test_case01_title_bottom01"]
  /// test(case01) sample 1
  #define test_case01_title_top01 "test_case01_title_top01"
  /// LOG : ["translation": "test(case01) sample 1", "name": "test_case01_title_top01", "key": "test_case01_title_top01"]

Case 02 : String

Want to make your default template look different?

.. doing it.

Conclusion

Why not try it?

You can also manage it by running it as a script command from the shell separately.

[iOSSampleApp] (https://github.com/igorkulman/iOSSampleApp) In this way, a single project can be packaged.
Thank you.
- I will try to make some more samples
