Ready-to-apply Dear ImGui themes for CImGui.jl: ~93 dark and light themes from multiple sources.

Apply a theme by name to the current imgui style (call once, e.g. during setup):

using ImGuiThemes
ImGuiThemes.apply_theme!("Cherry")        # or "Dracula", "Nord", "Photoshop", ...

Browse what's available:

THEMES                                     # Vector of all themes
[t.name for t in THEMES]                    # their names
ImGuiThemes.theme("Cherry")                 # one Theme (has .author, .tags, .colors, .style)

Drop this single call anywhere inside your imgui frame and it shows a standalone window with two bordered groups — dark and light — of radio buttons (one per theme, wrapping to the window width) to switch themes in one click:

ImGuiThemes.theme_picker()                  # window = true by default
ImGuiThemes.theme_picker(; window = false)  # or render the buttons inline

A runnable demo opens a real window with the picker next to imgui's demo window:

julia --project=examples examples/theme_picker_demo.jl

The catalogue (~93 themes, ≈22 light) is assembled from three sources:

ImThemes (47 themes) — the community database from Patitotective/ImThemes (MIT, © 2022 Patitotective), vendored in data/imthemes.toml. Each theme keeps its original author.

Curated hand-authored themes (8 themes, in src/themes/) — imgui-native Julia files, each transcribed or ported from a known upstream source:

• Solarized Light & Dark — palette by Ethan Schoonover
• Spectrum Light & Dark — Adobe Design System palette
• Light Rounded & White is White — Pascal Thomet / HelloImGui (MIT)
• Doug Binks Light — Doug Binks / Pacôme Danhiez
• Paper and Ink — TheAncientOwl (imgui issue #707)

ktsu themes (38 themes) — Catppuccin, Gruvbox, Everforest, Tokyo Night, Nord, Dracula, and more, generated at load time by a Julia port of ktsu-dev/ThemeProvider's palette→imgui engine (src/ktsu/engine.jl). Seed palettes are vendored in data/ktsu_themes.toml (MIT, © ktsu-dev — see data/ktsu-LICENSE).
