Add ability to load gherkin via http

[dkornishev]

Drop assumptions of file-system and add ability to run remote gherkin

[Goutte]

Right now, I get IsolateSpawnException: 'spawnFunction is not supported from a dom-enabled isolate. Please use spawnUri instead.' when I handle a GherkinParserTask with a Worker.

This is linked to the first issue of Worker : https://github.com/Dreckr/Worker/issues/1

Also, Gherkin feature files should be packed / unpacked to only have one transferred file.

The archive lib springs to mind.

Not sure what you mean.

I got double output (execution?) for scenario outline with a missing step

I mean that the server serving the static gherkin files should tarball them into one compressed file and that dherkin on client-side should be able to receive that compressed file and run the multiple features. Of course, it should also be able to receive one uncompressed gherkin feature file.

As for double output, i'm not sure what you mean, as I've got :

$ dart -c run.dart ./gherkin/everything.feature
I run some background
Компрессия! {table: []}
УРА!
Everything Works [works]
I run some background
I run some background
Columns are working hello world
COLUMN 2 {table: []} world
Columns are working goodbye world
Table1 {table: [{column1: A, column2: B, column3: C, column4: D}, {column1: E, column2: F, column3: G, column4: H}]} []
Table2 {table: []} []
COLUMN 2 {table: []} world
Table4 {table: []} []

I refactored the calling of the steps. Boilerplate generation is not right yet though.

I configured a small ForceServer to serve a tar of my folder of features.

tar.bz2 is one breath away.

Maybe this'll be of interest to you.

library aego_force_server;

import 'dart:io';

import 'package:args/args.dart';
import 'package:force/force_serverside.dart';
import 'package:archive/archive.dart';

void main(args) {
  var parser = new ArgParser();
  parser.addOption('port', abbr: 'p', defaultsTo: '8282', help: "Port for force_server");
  parser.addOption('host', abbr: 'o', defaultsTo: 'localhost', help: "Domain name of the host");
  parser.addOption('trials', abbr: 't', defaultsTo: './jungle', help: "Directory of the gherkin trials");
  parser.addFlag('verbose', abbr: 'v', defaultsTo: false, negatable: false);
  parser.addFlag('help',abbr: 'h', negatable: false);
  var argMap = parser.parse(args);
  if (argMap["help"] == true) {
    print(parser.getUsage());
    return;
  }

  ForceServer fs = new ForceServer(
      port: int.parse(argMap['port']),
      startPage: 'index.html',
      host: argMap['host']
  );

  fs.start().then((_) {
    print("Force Server started");
    registerRoutes(fs, argMap);
    print("Routes registered");
  });

}

void registerRoutes(ForceServer fs, ArgResults argMap) {
  /// JUNGLE TRIALS ----------------------------------------------------------
  var jungleTrialsDir = new Directory(argMap['trials']);
  fs.serve("/jungle/trials.tar").listen((request) {
    String targetPath = argMap['trials']+"/trials.tar";
    print("Serving ${targetPath}");
    List<File> jungleTrials = collectJungleTrials(jungleTrialsDir);
    generateTarSync(targetPath, jungleTrials);
    fs.serveFile(targetPath, request);
  });
  /// ------------------------------------------------------------------------
}

/// Collects `.feature` files [inDirectory] and sub-directories
List<File> collectJungleTrials(Directory inDirectory) {
  List<File> jungleTrials = [];

  // Recursively list directory contents, not following symbolic links.
  for (FileSystemEntity entity in inDirectory.listSync(recursive: true, followLinks: false)) {
    // Keep only .feature files
    if (entity is File && entity.path.endsWith('.feature')) {
      jungleTrials.add(entity);
    }
  }

  return jungleTrials;
}

/// Creates synchronously a tar file in [targetPath] containing all [files].
TarFile generateTarSync(String targetPath, List<File> files) {
  TarEncoder tarEncoder = new TarEncoder();
  Archive archive = new Archive();
  for (File trial in files) {
    print("  Add ${trial.path}, ${trial.lengthSync()} bytes");
    ArchiveFile archiveFile = new ArchiveFile(trial.path, trial.lengthSync(), trial.readAsBytesSync())
      ..mode    = 644
      ..ownerId = 0
      ..groupId = 0
      ..lastModTime = trial.lastModifiedSync().difference(new DateTime.fromMillisecondsSinceEpoch(0)).inSeconds;
    archive.addFile(archiveFile);
  }
  List<int> encoded = tarEncoder.encode(archive);
  File out = new File(targetPath);
  out.createSync(recursive: true);
  out.writeAsBytesSync(encoded);
}
