export-fsm

Some code to export Finite States Machines (FSM) made on http://madebyevan.com/fsm/ to our Java framework and maybe to JSON

Export to Java

The main goal is to export our drawn FSM from the website to the Java FSM framework made for our course, JFSM from edesmontils Symbols in transitions must be separated with , or , Symbols cannot contain ,

How to use

1. Copy the code (under or in export-java.min.js)

(()=>{const t=JSON.parse(localStorage.fsm);let n=[],e=[],o=[],s=[],a=[];t.nodes.forEach(t=>{e.push(t.text),t.isAcceptState&&s.push(t.text)}),t.links.forEach(e=>{"StartLink"===e.type?o.push(t.nodes[e.node].text):"SelfLink"===e.type?e.text.split(/,\s?/).forEach(o=>{n.includes(o)||n.push(o),a.push([t.nodes[e.node].text,o,t.nodes[e.node].text])}):e.text.split(/,\s?/).forEach(o=>{n.includes(o)||n.push(o),a.push([t.nodes[e.nodeA].text,o,t.nodes[e.nodeB].text])})}),clear&&clear();let r="// Code exported from http://madebyevan.com/fsm/ with https://github.com/grallm/export-fsm\n// Alphabet\nSet<String> A = new HashSet<String>();\n";for(let t of n)r+='A.add("'+t+'");\n';r+="\n// States\nSet<Etat> Q = new HashSet<Etat>();\n";for(let t of e)r+='Q.add(new Etat("'+t+'"));\n';r+="\n// Initial States\nSet<String> I = new HashSet<String>();\n";for(let t of o)r+='I.add("'+t+'");\n';r+="\n// Final States\nSet<String> F = new HashSet<String>();\n";for(let t of s)r+='F.add("'+t+'");\n';r+="\n// Transitions\nSet<Transition> mu = new HashSet<Transition>();\n";for(let t of a)r+='mu.add(new Transition("'+t[0]+'","'+t[1]+'","'+t[2]+'"));\n';r+="\n// Constructor\nAutomate afn = new AFN(A, Q, I, F, mu);\n\n",console.log(r)})();

2. Open the Developer Console (Windows: CTRL+Maj+I, Mac: CMD+OPT+I)
3. Paste the code and press Enter
4. Copy the Java code (you can right click and click on 'Copy')

TODO

• Read the localStorage.fsm (and understand the JSON format)
• Compose the Java code, log it in console
• Make a minified file
• Export directly a Java file
• Chrome Extension : choose names ?
• Choose variable names (to allow to have multiple FSM exported without any variable with same names) -> No Java variables for A, I, F, Q

Export to JSON

Try to export an easily JSON file, maybe create a Chrome extension to import and export with one button
