Contact Info Parser

Parses input and creates contacts with Name, Phone Number, and Email if they are found

Getting Started

Prerequisites

Visual Studio with C# support

Installing

On Windows

Building with Visual Studio:

Clone the repo and open the solution (.sln) file
Press "Start" and the application will build
Locate the executable file in the "ContactInfoParser\ContactInfoParser\bin\Debug" directory

How To Use

Running the Application

Locate the executable file in the "ContactInfoParser\ContactInfoParser\bin\Debug" directory and run the following commands in a command window

The files in the "Tests" directory will be run when no files are given as arguments when the program is executed.

Without file given as argument (using bash):

$ ./ContactInfoParser.exe
Looking for contacts in '../../Tests\ContactInfoEx1.txt'
Looking for contacts in '../../Tests\ContactInfoEx2.txt'
Looking for contacts in '../../Tests\ContactInfoEx3.txt'

Name: John Doe
Phone: 4105551234
Email: [email protected]

Name: Jane Doe
Phone: 4105551234
Email: [email protected]

Name: Bob Smith
Phone: 17035551259
Email: [email protected]

With a file given as an argument (using bash):

$ ./ContactInfoParser.exe ../../Tests/ContactInfoEx1.txt

Name: John Doe
Phone: 4105551234
Email: [email protected]

To change the location the program looks for resources (firstNames.csv, lastNames.csv): Edit the resourcesDir variable in BusinessCardParser.cs to the desired directory.

How it Works

1. A file is opened and all of its contents are read
2. Each line of the file contents is checked against several regular expressions (Name, Phone, Email)

   1. Once a phone number or email is found for a contact, it is not looked for again.

   2. Problems arise when looking for names in the business card information which includes the following:

      Bob Smith
      Software Engineer
      Decision & Security Technologies
      ABC Technologies
      123 North 11th Street
      Suite 229
      Arlington, VA 22209
      Tel: +1 (703) 555-1259
      Fax: +1 (703) 555-1200
      [email protected]
      

      Lines such as "Software Engineer" and "ABC Technologies" match the regular expression for names but should not be recognized as one.

      Therefore, when a potential name is found, the first and last name are checked against a set of first and last names read in and initialized (only once!) when a BusinessCardParser is constructed.

      1. If the first name is in the first name set: +1 points
      2. If the last name is in the last name set: +2 points

      The name with the highest score is selected
