Full Changelog: v1.0.4...v1.0.5

v1.0.4 A lot of cool stuff!

Hello y'all!

New Hellwal release! I some cool stuff :)

I forgot to acknowledge some people in v1.0.3 so I'm doing it here right now:

• thanks for fixing Makefile and ivaild free usage: @MalcolmReed-ent
• thanks for rofi template @nashluffy

---

Now regarding v1.0.4, there are quite a few new flags, FINALLY --version flag, --skip flags and --preview & --preview-small alpha variable that you can use in templates and some templates for other programs. Enjoy!

Important

Last verision had really strange bug with saving cache, so if something is not working use --no-cache flag or delete ~/.cache/hellwal/cache folder to be 100% sure

Full Changelog for 1.0.4:

• added --version flag
• added --skip-luminance-sort flag, it makes palette more similar to pywal, and less "predictable". Some people may want that, effect itself is kinda interesting and worth trying.
• changed visuals of color blocks - they are 3 spaces wide, it's more visible now
• added --preview and --preview-small cmdline argument
• added alpha variable, you can set alpha by providing it right after keyword in templates (e.g. "%% color1.hex alpha=0.5%%") - requested in issues by @chinh4thepro
• added --skip-term-colors - it skips setting colors(printing escape codes) to the terminals - requested in issues by @SherLock707
• added new templates for zathuram mako, dwl and fuzzel thanks to @amolinae06
• separeted color related functions from hellwal.c into its own header only library

Thanks for interest and support! :D

v1.0.2 Important fixes, and caching!

v1.0.2

Hello! New verision is up :)

It's mainly to fix some really imporant bugs with malloc, but I added cachig color palettes - it's saved to ~/.cache/hellwal/cache/wallpapername.hellwal.
So now if you want to apply color palette from already computed wallpaper it will just read it as a theme from this directory.

Note: any addional options like --light, --color, --dark, --bright-offset, are NOT saved to cached palettes, for better functionality cached palette is saved only from raw image, rest is computed on fly.

Time comparision on my machine:

Without caching:

dh » time ./hellwal --no-cache -q -i $wallpaper

real    0m0,074s
user    0m0,065s
sys     0m0,008s

With pre-cached wallpaper:

dh » time ./hellwal -q -i $wallpaper

real    0m0,001s
user    0m0,001s
sys     0m0,000s

Changelog for 1.0.2: (Click to expand)

• changed arc4random() to rand(), because it's not available on all platforms

• changed rand() to arc4random()

• created palettes caching

• added '--no-cache' cmd line argument

• fixed applying addtional arguments for themes

v1.0.1
