file_type_detector_sfedu

file_type_detector_sfedu is a Ruby gem that allows you to determine the type of files based on their extension or content.

Installation

Add this gem to your Gemfile and run bundle install:

gem "file_type_detector_sfedu"

Alternatively, install it directly using the gem command:

gem install file_type_detector_sfedu

Usage

To use the gem, you need to call the check method with a parameter in the form of a file path:

require "file_type_detector_sfedu"

puts FileTypeDetector.check("path/to/your/file.pdf") # if it's truly pdf, value will be true, unless - false

check method will automatically detect the file type by its extension and tell if its contents match the extension.

You can also use a specific detector:

puts FileTypeDetector.pdf_check("path/to/your/real_pdf.pdf")    # true
puts FileTypeDetector.pdf_check("path/to/your/fake_pdf.pdf")    # false

puts FileTypeDetector.docx_check("path/to/your/real_docx.docx") # true
puts FileTypeDetector.docx_check("path/to/your/fake_docx.docx") # false

You can also run all the detectors on the file to determine its type using the identify method:

puts FileTypeDetector.identify("path/to/your/real_pdf.pdf")   # "pdf"
puts FileTypeDetector.identify("path/to/your/real_xml.pdf")   # "xml"
puts FileTypeDetector.identify("path/to/your/real_docx.docx") # docx
puts FileTypeDetector.identify("path/to/your/real_jpeg.png")  # jpeg
puts FileTypeDetector.identify("path/to/your/unknown.png")    # nil
