clrsync

A theme management tool for synchronizing color schemes across multiple applications. clrsync allows you to define color palettes once and apply them consistently to all your terminal emulators, editors, and other configurable applications.

Features

• Unified Color Management: Define color palettes in TOML format and apply them across multiple applications
• CLI & GUI: Choose between a command-line interface or a graphical editor
• Live Reload: Define post-apply hooks (configurable per template)
• Flexible Color Formats: Support for HEX, RGB, HSL with multi-component access (e.g., {color.r}, {color.hex}, {color.hsl})
• Pre-built Themes: Includes popular themes

Building

Prerequisites

• C++20 compatible compiler (GCC, Clang, or MSVC)
• CMake or Meson
• OpenGL

Using CMake

mkdir build && cd build
cmake ..
cmake --build .

Using Meson

meson setup builddir
meson compile -C builddir

Installation

After building, you'll have:

• clrsync_cli - CLI
• clrsync_gui - GUI
• libclrsync_core - Shared lib

Configuration

Create a configuration file at ~/.config/clrsync/config.toml:

[general]
palettes_path = "~/.config/clrsync/palettes"
default_theme = "dark"

[templates.kitty]
input_path = "~/.config/clrsync/templates/kitty.conf"
output_path = "~/.config/kitty/clrsync.conf"
enabled = true
reload_cmd = "pkill -SIGUSR1 kitty"

Palette Files

Create palette files in your palettes_path directory:

# ~/.config/clrsync/palettes/dark.toml
[general]
name = "dark"

[colors]
background = "#111318FF"
surface = "#1E1F25FF"
surface_variant = "#282A2FFF"

foreground = "#E2E2E9FF"
foreground_secondary = "#A8ABB3FF"

accent = "#00AA56FF"
outline = "#44474FFF"
shadow = "#00000080"
cursor = "#FFFFFFFF"

error = "#FF5F5FFF"
warning = "#FFC966FF"
success = "#6AD68BFF"
info = "#5DB2FFFF"

term_black   = "#111318FF"
term_red     = "#FF5F5FFF"
term_green   = "#00AA56FF"
term_yellow  = "#FFC966FF"
term_blue    = "#5DB2FFFF"
term_magenta = "#DEBCDFFF"
term_cyan    = "#86C9FFFF"
term_white   = "#E2E2E9FF"

term_black_bright   = "#33353AFF"
term_red_bright     = "#FFB780FF"
term_green_bright   = "#00CC6AFF"
term_yellow_bright  = "#FFD580FF"
term_blue_bright    = "#86C9FFFF"
term_magenta_bright = "#F0D6F0FF"
term_cyan_bright    = "#BFEFFFFF"
term_white_bright   = "#FFFFFFFF"

Template Files

Create template files using color variables with flexible format specifiers:

# ~/.config/clrsync/templates/kitty.conf
cursor              {foreground}
cursor_text_color   {background}

foreground            {foreground}
background            {background}
selection_foreground  {foreground_secondary}
selection_background  {surface}
url_color             {accent}

color0      {background}
color1      {term_red}
color2      {term_green}
color3      {term_yellow}
color4      {term_blue}
color5      {term_magenta}
color6      {term_cyan}
color7      {term_white}

Color Format Specifiers

Access color components using dot notation:

# HEX formats
{color}                    # Default: #RRGGBB
{color.hex}                # #RRGGBB
{color.hex_stripped}       # RRGGBB
{color.hexa}               # #RRGGBBAA
{color.hexa_stripped}      # RRGGBBAA

# RGB components (0-255)
{color.rgb}                # rgb(r, g, b)
{color.r}                  # Red component
{color.g}                  # Green component
{color.b}                  # Blue component

# RGBA (alpha normalized 0-1)
{color.rgba}               # rgba(r, g, b, a)
{color.a}                  # Alpha component

# HSL (hue 0-360, saturation/lightness 0-1)
{color.hsl}                # hsl(h, s, l)
{color.h}                  # Hue component
{color.s}                  # Saturation component
{color.l}                  # Lightness component

# HSLA (hue 0-360, saturation/lightness/alpha 0-1)
{color.hsla}               # hsla(h, s, l, a)
{color.a}                  # Alpha component

Usage

CLI

List available themes:

clrsync_cli --list-themes

Apply the default theme:

clrsync_cli --apply

Apply a specific theme:

clrsync_cli --apply --theme rose-pine

Apply a theme from a file path:

clrsync_cli --apply --path /path/to/theme.toml

Show available color variables:

clrsync_cli --show-vars

Use a custom config file:

clrsync_cli --config /path/to/config.toml --apply

GUI

Launch the graphical editor:

clrsync_gui

The GUI provides:

• Color Scheme Editor: Visual palette editor with color pickers
• Template Editor: Edit template files
• Live Preview: See changes in real-time

Example Themes

The project includes several pre-configured themes in example_config/palettes/:

• dark.toml
• light.toml
• flexoki.toml
• flexoki-light.toml
• rose-pine.toml
• rose-pine-moon.toml
• rose-pine-dawn.toml
