About

This package just simplifies working with go/* packages to parse a source code. Initially the package was written to simplify code generation.

Quick start

package main

import (
    "fmt"
    "go/build"

    "github.com/xaionaro-go/gosrc"
)

func assertNoError(err error) {
	if err != nil {
		panic(err)
	}
}

func main() {
	dir, err := gosrc.OpenDirectoryByPkgPath(&build.Default, "github.com/xaionaro-go/gosrc", false, false, false, nil)
	assertNoError(err)

	if len(dir.Packages) != 1 {
		panic("expected one package")
	}
	pkg := dir.Packages[0]

	for _, file := range pkg.Files {
		for _, s := range file.Structs() {
			fields, err := s.Fields()
			assertNoError(err)
			fmt.Println("amount of fields:", len(fields), ";\t amount of methods:", len(s.Methods()), ";  \tstruct name:", s.Name())
		}
	}
}

The output is:

amount of fields: 2 ;    amount of methods: 0 ;         struct name: Directory
amount of fields: 2 ;    amount of methods: 1 ;         struct name: ErrPackageNotFound
amount of fields: 5 ;    amount of methods: 7 ;         struct name: Field
amount of fields: 2 ;    amount of methods: 0 ;         struct name: TypeNameValue
amount of fields: 3 ;    amount of methods: 12 ;        struct name: File
amount of fields: 1 ;    amount of methods: 0 ;         struct name: Func
amount of fields: 6 ;    amount of methods: 5 ;         struct name: Package
amount of fields: 3 ;    amount of methods: 5 ;         struct name: Struct
