How it works

Advanced explanation

Inputs can be:

1. local file
2. url
3. bytes from stdin

The type of each input is inferred automatically, and it continues through the pipeline until it reaches the output format the user requested.

For example, if the user runs:

mcat file.docx file.pdf -o inline

mcat will:

• Convert both file.docx and file.pdf into a single Markdown file
• Convert that Markdown into HTML
• Convert the HTML into an image
• Convert the image into an inline terminal image and print it

You can also start from the middle of the pipeline.
For example:

mcat file.html -o image > image.png

This starts at an HTML file and directly converts it into a PNG image.

• Markdown - set when -o md or when the stdout isn't the terminal (piped)

• Markdown Viewer is markdown with ANSI formatting, and is the default for any non video / image file. (the -c flag forces it)

• HTML set when -o html -- only works for non image / video files

• PNG Image set when -o image and gives an image

• Interactive Viewer set when -o interactive or -I and launches an interactive view to zoom and pan the image in the terminal.

• Inline Display set when -o inline or -i and prints the content as image in the terminal

mcat massive_image.png -I              # zoom and pan the image interactively in the terminal

#--------------------------#
#  What I use it most for  #
#--------------------------#

mcat ls                                # To find the image i was looking for
