gobpmn

Description

gobpmn is an experimental library that makes it possible to reflect

static structs,
typed and generic maps

in Go and create business process models out of it.

As a modeler with a CLI, gobpmn is a monorepo with clear encapsulation.

STILL IN DEVELOPMENT

Requirements

Go >= 1.24

Optional:

Saxon >= 12.5 (Requires Java >= 23)

Install

Clone the repository or the download the .zip-File of the repository
Install the latest gobpmn version as a package within a module with go get
Install the latest gobpmn version as a package outside of a module with go install

go get github.com/deemount/gobpmn@latest
go install github.com/deemount/gobpmn@latest

How To

package main

import (
    "log"
    "github.com/deemount/gobpmn"
)

type Process struct {
    Def             gobpmn.Repository
    IsExecutable    bool
    Process         gobpmn.BPMN
    StartEvent      gobpmn.BPMN
    FromStartEvent  gobpmn.BPMN
    Task            gobpmn.BPMN
    FromTask        gobpmn.BPMN
    EndEvent        gobpmn.BPMN
}

func (p Process) GetDefinitions() gobpmn.Repository {
    return p.Def
}

func main() {
    _, err := gobpmn.FromStruct(Process{})
    if err != nil {
        log.Fatalf("ERROR: %s", err)
        return
    }
}

package main

import (
    "log"
    "github.com/deemount/gobpmn"
)

var Process = map[string]any{
    "Def":                 gobpmn.Definitions(),
    "IsExecutable":        true,
    "Process":             gobpmn.BPMN{Pos: 1},
    "StartEvent":          gobpmn.BPMN{Pos: 2},
    "FromStartEvent":      gobpmn.BPMN{Pos: 3},
    "Task":                gobpmn.BPMN{Pos: 4},
    "FromTask":            gobpmn.BPMN{Pos: 5},
    "EndEvent":            gobpmn.BPMN{Pos: 6},
}

func main() {
    type T any
    _, err := gobpmn.FromMap[T](Process)
    if err != nil {
        log.Fatalf("ERROR: %s", err)
        return
    }
}

Command Line Interface (CLI)

gobpmn has now a command line interface to better introduce some use cases in the future, like updating, configuration, debugging, running tests, modelling, parsing models to bpmn, json or xml and using saxon to transform.
