Trying to create a fileName parser for kibibit. This should get the following data: 1) fileName (no extension) 2) extension 3) all `tags` (words after the 1st dot (excluding the extension and hidden file dot) 4) hidden state of file

parseFileNames.js

var testFileName = 'kaki.js';
var testHiddenFile = '.hidden';
var testHiddenWithExtension = '.hidden.js';
var testTags = 'kaki.test.js';
var testHiddenWithTags = '.kaki.test.js';

function analizeFileName(fileName) {
  // input not a string
  if(!angular.isString(fileName)) {
    return {error: "fileName should be a string"};
  }
  
  // input is invalid
  if(fileName.split('.').join('').length === 0) {
    return {error: "fileName is empty or invalid"};
  }
  
  // INIT
  var returnData = {
    fileName: fileName
  };
  var fileArray = fileName.split(/(\.)/g);
  
  // GET ALL NEEDED DATA
  returnData.isHidden = isHidden(fileArray);
  fileArray = returnData.isHidden ? removeParsedParts(fileArray, true /* isHidden */) : fileArray;
  returnData.fileExtension = getExtension(fileArray);
  fileArray = returnData.fileExtension ? removeParsedParts(fileArray, false /* isHidden */, true /* hasExtension */) : fileArray;
  returnData = angular.extend(returnData, getTags(fileArray));
  returnData.fileName = returnData.isHidden ? '.' + returnData.fileName : returnData.fileName;
  
  return returnData;
}

function isHidden(fileArray) {
  return fileArray[0] === '' && fileArray[1] === '.';
}

function getExtension(fileName) {
  // expects fileName without hidden part
  var fileParts = file.split('.');
  if (fileParts.length > 2) {
    return fileParts[fileParts.length - 1];
  } else {
    // no extension
    return false;
  }
}

function getTags(fileArray) {
  var onlyName = fileArray.join('');
  var splitByDot = onlyName.split('.');
  if (splitByDot.length < 2) {
    return { fileName: onlyName, tags: [] };
  }
  splitByDot.splice(0, 1);
  return { fileName: onlyName, tags: splitByDot};
}

function removeParsedParts(fileArray, isHidden, hasExtension) {
  var _fileArray = angular.copy(fileArray);
  if(isHidden) {
    _fileArray.splice(0, 2);
  }
  if(hasExtension) {
    _fileArray.splice(_fileArray.length - 2, 2);
  }
  
  return _fileArray;
}

Trying to create a fileName parser for kibibit.

This should get the following data:

1. fileName (no extension)
2. extension
3. all tags (words after the 1st dot (excluding the extension and hidden file dot)
4. hidden state of file (in projects sense. not file system sense)

output should be an object:

{
  fileFullName: '.complete.file.name.js',
  fileName: '.complete.file.name',
  isHidden: true,
  fileExtension: 'js',
  tags: [ 'file', 'name' ]
}
