LogicPull

LogicPull gives you the tools to quickly create advanced question and answer interviews for end-users. The answers are then combined with templates to produce all the documents you need. Take the tour to find out more about what LogicPull.

Features

LogicPull was initially developed to save time and money creating the many legal documents needed for a court preceding. It has since expanded to handle the assembly of PDF, DocX, RTF and XML documents for any project. It is a cloud based automated document assembly service. We give you the tools to quickly create an advanced question and answer interview to be completed by an end user, which in turn creates an answer set to be combined with a template to produce documents.

• Multiple Document Formats Supported
• Create Complex Branching Logic
• Keep your Data and Documents in the Cloud
• Save Progress on Client Interviews
• Attach Custom Templates to Guided Interviews
• Preview your Work Before it Goes Live
• Send Processed Documents Automatically

FAQ

• What exactly can I do with LogicPull?

  You can collect answers to dynamic questions through a form built with our editor, then combine those answers with a template to produce PDF, RTF, XML or DocX documents.

• What are templates?

  LogicPull uses EJS to combine with answer sets to produce the documents you need. Please see this article for more information on how to work with templates.

• Do I need a technical background to use LogicPull?

  LogicPull tries to make it as easy as possible to create, edit, and manage guided interviews. Writing templates does require a basic understanding of how conditional logic works.

• What browsers does LogicPull support?

  • Google Chrome
  • Safari
  • Firefox
  • Opera
  • Microsoft Internet Explorer 8.0+

Installation

A full installation tutorial on a Ubuntu 12.04.3 64 bit server is available here. To build LogicPull locally, please see this article.

System Requirements

The minimum memory requirement for LogicPull, and all its components is 256 MiB of memory. With only the minimum amount of memory available, the interviews will take longer to process than normal, but will complete successfully. This minimum requirement is dependent on the number of users connected to the server, and the complexity of the tasks being performed.

Software Requirements

LogicPull uses the software packages listed below in our server side tech stack. For detailed instruction on how to install LogicPull on a server, please see here.

Package	Description	License
MongoDB	Database used to store all interviews, and answer sets.	AGPL
nodeJS	Server side JavaScript platform.	MIT
stunnel	Decryption for SSL traffic.	GPL
nginx	Server for static resources.	BSD

TODO

Editor

• Complete Validations. The following validations are not yet implemented.
  • min_date
  • max_date
    To perform validation for these properties, use 'after logic' and check the date using dateDifference().
• Add descending order into number dropwdown in the editor
• Add drop down list of months as a default in the date field
• Create undo function
• Add a variable lookup/finder in the editor
• Select multiple nodes from graph and move
• Disallow duplicate variable field names

Viewer

• Allow users to change a past variable without having to go back to that question and start from there

Known Issues

• The Settings button in the editor view does not work when the debug preview is running.
• Once a date is entered into the viewer, it cannot be cleared, only changed.
• When adding question text in the editor, the 'Toggle HTML' button does not reset when the question is closed. To prevent any issues, make sure the default compiled view is visible when exiting the question.
• Adding format in the editor may interfere with the parsers ability to recognize templates. For example, when bolding text, the editor may insert <%<bold> someVar %></bold>. This would prevent the parser to recognize the variable someVar since the <bold> tag was inserted in between the template tags <% %>. To prevent this, you can switch to 'HTML View' and move the bold tag to outside the template tag. This is a rare bug that seems to come up only when re-bolding text.

Possible Improvements

• Replace ejs templating engine with more robust solution
• Replace apache FOP with XMLMind
• Use mardown instead of wysihtml5 in the editor
