Code Gen

This tool built for generating code template via CLI.

Build & Run

go build && ./codegen

Setup Config

Create a config.toml with following format and place next to ./codegen

[[tasks]]
name = "Create a MVC Class"

[tasks.fields]

    [tasks.fields.ClassName]
    type = "StringInput"
    message = "Class Name"

    [tasks.fields.MyVariable]
    type = "String"
    value = "MY_VARIABLE"

    [tasks.fields.ClassType]
    type = "StringInput"
    message = "Class Type (M=Model, V=View, C=Controller)"

    [tasks.fields.Map]
    M = "Model"
    V = "View"
    C = "Controller"

[[tasks.files]]
templatepath = "test/template/template.java"
exportpath = "test/output/{{.Title \"ClassName\"}}.java"

Create Template

Template are renderred by Go Template, like this:

{{if .Equal "ClassName" "MyClass"}}// MyClass{{end}}
public class {{.Print "ClassName"}} {
    private static final String {{.Constant "MyVariable"}} = "HelloWorld";
    public static void main(String args[]){
        System.out.println({{.Print "MyVariable"}});
    }
}

Function availiable in template

Name	Description	Example	Output
Print	Print field value	{{.Print "MyField"}}	your exact input
Equal	Check if field value equal to string	{{if .Equal "MyField" "foo"}} bar {{end}}	bar
Title	Turn value to title case	{{.Title "MyField"}}	ConvertedInput
Camel	Turn value to camel case	{{.Camel "MyField"}}	convertedInput
Constant	Turn value to constant case	{{.Constant "MyField"}}	CONVERTED_INPUT
Underline	Turn value to underline case	{{.Underline "MyField"}}	converted_input
Dash	Turn value to dash case	{{.Dash "MyField"}}	converted-input
Path	Turn value to path case	{{.Path "MyField"}}	converted/input
Package	Turn value to package case	{{.Package "MyField"}}	converted.input

Roadmap

28/4/2019

• Basic template generation
• CLI menu & prompt
• Template config format
• Print variable to template
• String conversion for template (Title, Constant, Camel, Dash)
• If case for template (Value compare)

29/4/2019

• Global variable

5/5/2019

• More String conversion for template (package, file/path, under_line)

TBC

• Windows CLI word missing bug
• Windows <? -> <? bug
