Image viewer made for my requirements.

You will need ghc, stack and probably cabal

Also your system will need GTK3.

stack build in root directory will build the program.

It does not have any GUI whatsoever and intended to be invoked from command line. It does not have any options and treats all input as a list of files. If there is only one file, and it is a directory, it will descend and load all files from it; it is recursive. If there aren't any, it loads all files from current directory.

Keybindings are the following:

space and enter will load next random image

backspace will load previous random image

e will load next sequential image (they are sorted by name), w will load previous. Note that moving sequentially will not affect random order, so space, e, e, backspace will result in the same as space, backspace

p prints file name to stdout, also copies its full path into system buffer

y copies full path to file into system buffer, also prints it to stdout

q and ESC exits program.

0 will return image sequence to the first image. If you want to view all images in sequence, press 0 after the start and then use e and w to navigate.
