grunt-soy-compile Build Status

Compile soy template files including XLIFF language handling.

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-soy-compile --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-soy-compile');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade

Soy compile task

Run this task with the grunt soycompile command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Options

jarPath

REQUIRED

Type: String Default: null

The path to the google clousure template comipler jar files. Put the SoyToJsSrcCompiler.jar and SoyMsgExtractor.jar in one directory and set this jarPath option as absolute path to the containing folder.

You can download the jar files here:

ext

Type: String Default: ".js"

The used file extension for the compiled template JS Files.

msgextract

Type: Boolean Default: false

Use the message extractor to generate the xliff files out of the soy messages. This make only sense in combination with the extractmsgpath option.

extractmsgpath

Type: String Default: null only relevant if msgextract = true

The relative path to the folder in witch the xliff files will be generated. Note: Soy overwrites the whole xliff file during every extraction. So it eventually makes sense to use the infusemsgpath option.

infusemsgpath

Type: String Default: [ extractmsgpath ] only relevant if msgextract = true

The relative path to the folder from wich the compiler grabs the xliff generated files. If this option has not been defined the extractmsgpath will be used.

Info: If you got a software to fill the generated xliff files with the translations you can use this option to generate the localized templates.

Note: If the soy compiler won't find a translation element within the xliff it uses the default defined within teh message.

sourceLang

Type: String Default: "en_GB" only relevant if msgextract = true

The source language you wrote your soy templates.

languages

Type: Array Default: [] only relevant if msgextract = true

An array of languages the compiler will generate.

singleLangXLIFF

Type: String Default: null only relevant if msgextract = true

By setting this value to a language code of languages it will only generate one xliff file.

compileflags

Type: Object Default: null

You can use this option to define your required compile flags. See Javascrip useage docs.

Example:

```
    src: ['test/tmpls/test.soy', 'test/tmpls/test.nr2.soy']
    dest: 'tmp/testCombined/flags.js'
    options:
        jarPath: "~/local/soy"
        compileflags:
            shouldGenerateJsdoc: true
            shouldProvideRequireSoyNamespaces: true
            shouldDeclareTopLevelNamespaces: true
            codeStyle: "concat"
```

isUsingIjData [ deprecated ]

Type: Boolean Default: false

Add's the compile param --isUsingIjData.

NOTE: This feature is deprecated. So please use the compileflags option.

Usage Examples

simple

A simple example without using the extractor and soy translation features.

soycompile: {
    mytask: {
        expand: true, 
        cwd: 'relative/path/to/sources',
        src: ["*.soy"],
        dest: "relative/path/for/results",
        options: {
            jarPath: "/absolute/path/to/the/jar/files"
        }
    }
}

to one file

A simple to compile multiple soy files into one single js file.

soycompile: {
    mytask: {
        src: ['test/tmpls/**/*.soy']
        dest: 'relative/path/for/results/myTemplates.js'
        options: {
            jarPath: "/absolute/path/to/the/jar/files"
        }
    }
}

complex

A complex example using the extractor and soy translation features.

soycompile: {
    mytask: {
        expand: true, 
        cwd: 'relative/path/to/sources',
        src: ["*.soy"],
        dest: "relative/path/for/results",
        options: {
            jarPath: "/absolute/path/to/the/jar/files",
            msgextract: true,
            sourceLang: "en_GB",
            languages: [ "en_GB", "de_DE", "jp_JP" ],
            singleLangXLIFF: "de_DE"
            extractmsgpath: "relative/path/for/generated/xliffs",
            infusemsgpath: "relative/path/to/translated/xliffs"
        }
    }
}

NOTE: If you use the "to one file" Syntax ( using without expand: true ) the generated xliff files will also be generated info and are required to infuse by a single file per language ( e.g. relative/path/for/generated/xliffs/myTemplates_de_de.xlf, relative/path/for/generated/xliffs/myTemplates_gb_en.xlf, ... ).

For more examples on how to use the expand API shown in the glob_to_multiple example, see "Building the files object dynamically" in the grunt wiki entry Configuring Tasks.

Additional info

Compile only a single file

  • if you use grunt-regards instead of grunt-contrib-watch to track chnaging files, the compiler will only compile the changed file.
  • if you want to compile only the changed file by grunt-contrib-watch you have to define the watch optionoptions: { spawn: false }, beause with a spawned task i can not catch the changed event through multiple threads.

Path restrictions

  • It's not possibel to use a , within the paths to the grunt, xliff, soy or js files, because it's the java command file delimiter.

differnet jarPaths

If you have to define different paths to the jarFiles for differnet developers i use the folowing solution. In many projects i define a file config.json to the root witch will be ignored by .gitignore. Within this file every developer can change the configutation for it's own development envorinment.

To set the jarPath i define something like that in the config.json.

{
    "grunt":{
        "soyJarPath": "/Library/tcs_utils"
    }
}

Within the Gruntfile.js you set:

// read the config file
var _conf = grunt.file.readJSON('config.json')

grunt.initConfig({
    soycompile: {
        mytask: {
            expand: true, 
            cwd: 'relative/path/to/sources',
            src: ["*.soy"],
            dest: "relative/path/for/results",
            options: {
                // define a deviating path in `config.json` under `...{ "soycompile":{"jarPath": "/absolute/path/to/another/jar/files"}}...`. Otherwise use a default.
                jarPath:  (typeof __conf !== "undefined" && __conf !== null ? (_ref = __conf.grunt) != null ? _ref.soyJarPath : void 0 : void 0) || "/absolute/path/to/the/jar/files",
            }
        }
    }
});

Attention

You have to be carefull with filenames containing multiple dots! I had this problem by uglifing my generated soy templates. See this grunt issue for more information and this StackOverflow question for a solution.

Todos

  • implement test cases to check for correct template generation.
