MG Transport Library

This library provides different functions like error-reporting, logging, localization, etc. in order to make it easier to create transports.
Usage:

package main

import (
    "os"
    "fmt"
    "html/template"

    "github.com/gin-gonic/gin"
    "github.com/gobuffalo/packr/v2"
    "github.com/retailcrm/mg-transport-core/core"
)

func main() {
    app := core.New()
    app.Config = core.NewConfig("config.yml")
    app.DefaultError = "unknown_error"
    app.TranslationsPath = "./translations"
    
    app.ConfigureRouter(func(engine *gin.Engine) {
        engine.Static("/static", "./static")
        engine.HTMLRender = app.CreateRenderer(
            func(renderer *core.Renderer) {
                // insert templates here. Example:
                r.Push("home", "templates/layout.html", "templates/home.html")
            }, 
            template.FuncMap{},
        )
    })
    
    if err := app.Prepare().Run(); err != nil {
        fmt.Printf("Fatal error: %s", err.Error())
        os.Exit(1)
    }
}

Resource embedding

packr can be used to provide resource embedding. In order to use packr you must follow this instruction, and provide boxes with templates, translations and assets to library. Example:

package main

import (
    "os"
    "fmt"
    "html/template"

    "github.com/gin-gonic/gin"
    "github.com/gobuffalo/packr/v2"
    "github.com/retailcrm/mg-transport-core/core"
)

func main() {
    static := packr.New("assets", "./static")
    templates := packr.New("templates", "./templates")
    translations := packr.New("translations", "./translate")
    
    app := core.New()
    app.Config = core.NewConfig("config.yml")
    app.DefaultError = "unknown_error"
    app.TranslationsBox = translations
    
    app.ConfigureRouter(func(engine *gin.Engine) {
        engine.StaticFS("/static", static)
        engine.HTMLRender = app.CreateRendererFS(
            templates, 
            func(renderer *core.Renderer) {
                // insert templates here. Example:
                r.Push("home", "layout.html", "home.html")
            }, 
            template.FuncMap{},
        )
    })
    
    if err := app.Prepare().Run(); err != nil {
        fmt.Printf("Fatal error: %s", err.Error())
        os.Exit(1)
    }
}

Migration generator

This library contains helper tool for transports. You can install it via go:

$ go get -u github.com/retailcrm/mg-transport-core/cmd/transport-core-tool

Currently, it only can generate new migrations for your transport.
