An image deletion utility.

It is suitable for rapidly going through a folder with a large number of images one by one and deleting as needed. The deleted images are collected in a trash folder specified at the command line.

The code is written in 3 different languages: python, java and c. The functionality and interface provided by code in each of these languages is exactly the same.

I did this as an experiment to observe two things:

1. How to interface with gtk in different languages.
2. How long it'll take to develop the exact same program in each of the languages.

Conclusions:

1. Interfacing with gtk is fairly straight forward in all the languages.
2. As anybody can guess, the c program took most time. While java and python versions were programmed in apprx. 3-4 hours each, the c code took approximately double that time. The additional complexity was mostly due to the complicated memory management API for GObjects.

Build all language versions:

make all

Build individual versions:

make build_java
make build_c

Install default version (c):

make install

Install individual language versions:

make install_py
make install_java
make install_c

Launch the application with command line arguments: source dir path, trash dir path

e.g. > imagenot . ./trash

Once the window shows, use left and right arrow keys to move back and forth through the images. Press "d" to delete the current image.
