This is a work in progress to create a small and handy image viewer based on the pygtk toolkit.

Before installaing jkbiv, the following dependencies must be installed on your system:

• setuptools
• pygtk

To install jkbiv to your system, cd to the project directory and type the following command:

python setup.py install

If you want to hack on the code, type the following instead:

python setup.py develop

jkbiv [-h] [path]

-h

display help message

path

the file or directory to open

The setting of jkbiv can be set in ~/.jkbivrc, a dotfile inside the user's home directory. This program doesn't create the file; you have to create it manually. The config file is in ini format; here's an example of a config file:

[window]
fullscreen = false
width = 800
height = 600
[keymap]
quit = q
next = l <right> <C-n> <space>
prev = h <left> <C-p> <backspace>
fullscreen = f

The text enclosed by square brackets [] is the beginning of a section. Subsequent lines belong to the section until encountering a new section header. Options are in the form <key> = <value>.

Available sections and options are documented as follows.

The window section contains the settings of the main window. Available options are listed below:

The keymap section contains the shortcut bindings options. The keys are the function names, and the values are (zero, one or multiple) keys that are mapped to the function. For example, quit = q <C-x><C-c> maps both the q key and the Ctrl-x Ctrl-c key sequence to the quit function. Note that there are no whitespace characters between <C-x> and <C-c>. The symbols < and > are used to group modifiers and keys. When mapping these two keys, it is necessary to escape them as \< and \>. Following is a list of available functions:

Here are several functions I want to implement:

• auto reload when file or directory changes
• [Done] zoom in/out
• load file in background
• preload and cache adjacent images
