IMPORTANT:This repo is just a proof-of-work for my participation in Google Summer of Code 2018. This repo has been out of sync with the upstream repo since I started working on this and will continue to remain so (at least the master branch) in the future so that my commits are clearly visible

I have been selected as a student for the Google Summer of Code program to work for The Linux Foundation, more specifically the OpenPrinting project. My project was to build a tool which takes in different printing file formats and checks them for structural errors before sending it to the printer. This idea was taken from an open issue in the ippsample project.

The proposed linter program will take as input common print file formats and checks them for any structural or content errors. The linter should support basic raster formats such as PWG and CUPS rasters along with JPEG and PDF formats. The program can be used as a standalone program or as a command for the ippserver program to check the document submitted along with a job. The program also reports various job attributes such as job-impressions-xxx, job-media-sheets-xxx, job-pages-xxx. The skeleton file for the program has already been created by Michael R. Sweet from Apple Inc. and my work will start from it and build on top of it.

Refer to BUILD.md

Usage: ippdoclint [options] filename
Options:
  --help              Show program usage.
  --version           Show program version.
  -i content-type     Set MIME media type for file.
  -o name=value       Set print options.
  -v                  Be verbose.

• Try to test with files from as many different sources as possible and look for corner cases or exceptions.
• Merge the code into the upstream repo.

Working with OpenPrinting has been extraordinary as before (this is my second GSoC with them :) ). If anything, it was even better. I thank all my mentors for guiding me to write good code and making me a better developer. And I thank OpenPrinting for this excellent opportunity one more time. I will try my best to keep contributing to OpenPrinting regularly and I will be looking forward to working with them again.
