toml-rgb2ansi256

Convert RGB hex values to ANSI 256 color code in TOML document.

Install

After Rust Installation,

$ cargo install --git https://github.com/koyeung/toml-rgb2ansi256.git

Usage

Helix supports both RGB truecolor and ANSI 256 color index in themes. However, some terminal emulators still have no truecolor support. Below command could convert the hex RGB values into ANSI 256 color code:

$ cp $HOMEBREW_PREFIX/opt/helix/libexec/runtime/themes/github_dark.toml .
$ tail github_dark.toml
"severe.muted" = "#db6d2866"
"severe.subtle" = "#db6d2826"
"sponsors.emphasis" = "#bf4b8a"
"sponsors.fg" = "#db61a2"
"sponsors.muted" = "#db61a266"
"sponsors.subtle" = "#db61a226"
"success.emphasis" = "#238636"
"success.fg" = "#3fb950"
"success.muted" = "#2ea04366"
"success.subtle" = "#2ea04326"
$
$ toml-rgb2ansi256 < github_dark.toml > github_dark_ansi256.toml
$
$ tail github_dark_ansi256.toml
"severe.muted" = "167"
"severe.subtle" = "167"
"sponsors.emphasis" = "132"
"sponsors.fg" = "169"
"sponsors.muted" = "169"
"sponsors.subtle" = "169"
"success.emphasis" = "29"
"success.fg" = "71"
"success.muted" = "71"
"success.subtle" = "71"
$

Put github_dark_ansi256.toml into ~/.config/helix/themes/. :theme command should apply the theme with approximate colors.

Thanks

Thanks to rgb2ansi256 for color code conversion and toml_edit for format-preserving parsing.
