v0.11.0 - CLI & Palette Overhauls

Builtin Palettes

If possible, please verify any palettes you use!

• Palettes are now scraped from a few new sources with (theoretically) more accuracy. All palettes are deduplicated with -base16 -terminal-sexy and -gogh suffixes removed.
• Added Swamp & Swamp-Light by @masroof-maindak in #23

CLI

Custom Palette Support

Custom palettes can be added to $LUTGEN_DIR or <CONFIG DIR>/lutgen, for example:

• Linux: /home/alice/.config/lutgen
• macOS: /Users/Alice/Library/Application Support/lutgen
• Windows: C:\Users\Alice\AppData\Roaming\lutgen

Names are case-insensitive and parsed from the file stem, minus any file extensions. For example, ~/.config/lutgen/My-palette.txt would be avalable to use as my-palette.

Custom palettes work anywhere a builtin palette would, ie lutgen apply -p my-palette

Migrated from clap -> bpaf

• explicit separation between different algorithms adjacent arguments (ie, --gaussian-sampling --mean 0 --std-dev 20 --iters 128)
• flag aliases everywhere, due to context aware parsing of algorithm args preventing conflicts
• subcommand aliases (ie apply/a, generate/g, patch/p)
• Improved dynamic completions for files, palettes, and args
• Improved helptexts and added man page (man 1 lutgen)
• (maintainers): new completion generation commands: --bpaf-complete-style-<bash/zsh/fish>

Other Changes

• single file default output behavior restored (ie myimage-gruvbox.png). This now has a optional flag -d which can restore enabling directory output mode for single files (ie gruvbox/myimage.png)
• Improved lut caching eliminates false hits and ensures cache paths are unique to the individual colors (ie luts cached via lutgen apply -c ...)
• Palettes can be extended with custom colors by using them simultaneously
• Guess image types by @drainpixie in #21

New Contributors

• @drainpixie made their first contribution in #21

Special thanks

Thanks to @pacak for all the help in resolving the edge cases in bpaf ❤️

Full Changelog: v0.10.1...v0.11.0

v0.10.1

Library

• fix: skip over creation of the tree on small palette by @qti3e in #18

CLI

• feat: patch subcommand for text files, supporting #ABCDEF, rgb(4, 2, 0), and rgba(0, 1, 2, 0.5)
• feat: support 3 color hex codes in cli args (ie, #000)
• refactor: all spinners now print in stderr (to allow patch command's output to be easily piped from stdout)
• fix: output path logic

New Contributors

• @qti3e made their first contribution in #18

Full Changelog: v0.10.0...v0.10.1

v0.10.0

CLI (breaking change)

• All default outputs for single files will now match the behavior of multi file operations. The output path will be stored in a directory named by the palette, unless otherwise specified.
• The default shape parameter for GaussianRBF, the default interpolation algorithm, is now 128

Library

• Simple benchmarks
• Performance: refactor for kiddo v4
• Performance: optimize identity::generate
• Performance: enable fat lto, allow loop vectorization during build

Palettes

• Updated Biscuit Light by @ronindoll in #10
• Added swamp palette by @masroof-maindak in #11
• Added Dark Decay colorscheme by @Alxhr0 in #13
• Added Decayce by @Alxhr0 in #15

New Contributors

• @ronindoll made their first contribution in #10
• @Alxhr0 made their first contribution in #13

Full Changelog: v0.9.0...v0.10.0

v0.9.0

Library

• Internal refactors, moved typed rbf algorithms into a macro implementation (yay meta programming!).

CLI

• Added --preserve flag for all rbf algorithms, which will preserve the original images luminocity values, after interpolation.
  • This allows for combining --lum 0 --preserve to ignore all luminocity when interpolating, and to use the original images luminocity instead, for some really nice results.

Palettes

• Fixed Oxocarbon colors
• Added Carburetor palettes (regular, cool, and warm)
• Added Biscuit Dark & Biscuit Light palettes (#8)
• Added Mountain Fuji palette (#9)

New Contributors

• @tsukki9696 made their first contribution in #8
• @hikaruisasleep made their first contribution in #9

v0.8.2

Fixes rbf interpolation functions

Full Changelog: v0.8.1...v0.8.2

v0.8.1

What's Changed

• fix(palettes): Amends for a few palettes
• feat(palettes): Added Oxocarbon. by @Mujtabaasim in #4
• doc: Add Link to explain LUT by @coastalwhite in #5

• @coastalwhite made their first contribution in #5

Full Changelog: v0.8.0...v0.8.1

v0.8.0 - CLI Overhaul!

What's Changed

Functionality in the cli has been moved entirely within subcommands now:

• generate: generate a hald clut for external use
• apply: generate or use a hald clut, and apply it to an image
• completions: generates shell completions

This fixes issues where the completion scripts parse the subcommand as a custom color, and suggests to type the subcommand twice.

Custom colors also now need to be separated with a -- at the end of the command
