This sxiv (now un)stable version 26 (1d28627, 2020-01-16) side project has a different take on sxiv patching. It uses preprocessor directives to decide whether or not to include a patch during build time. Essentially this means that this build, for better or worse, contains both the patched and the original code. The aim being that you can select which patches to include and the build will contain that code and nothing more.

For example to include the image-mode-cycle patch then you would only need to flip this setting from 0 to 1 in patches.h:

#define IMAGE_MODE_CYCLE_PATCH 1

So if you have ever been curious about trying out sxiv patches then this may be a good starting point. Once you have found out what works for you and what doesn't then you should be in a better position to choose patches should you want to start patching from scratch.

Refer to https://github.com/muennich/sxiv for the original version and further details on sxiv, how to install it and how it works.

Patches included:

• alpha

  • the alpha patch allows sxiv to be embedded into applications that expects it, e.g. tabbed with alpha patch applied
