# Global default (no flags = global)
dvm set theme coolnight-ocean

dvm set theme coolnight-synthwave --workspace dev
dvm set theme tokyonight-night --app my-api
dvm set theme gruvbox-dark --domain backend
dvm set theme catppuccin-mocha --ecosystem my-platform

Via YAML

Themes can be embedded directly in resource YAML:

# In a Workspace YAML
spec:
  nvim:
    theme: coolnight-synthwave

# In an App YAML
spec:
  theme: tokyonight-night

# In a Domain YAML
spec:
  theme: gruvbox-dark

Apply with:

dvm apply -f workspace.yaml

Creating Custom Themes

Define a custom theme as a YAML resource:

apiVersion: devopsmaestro.io/v1
kind: NvimTheme
metadata:
  name: my-custom-theme
  description: My personalized colorscheme
  category: dark
spec:
  plugin:
    repo: "folke/tokyonight.nvim"
  style: "night"
  colors:
    bg: "#1a1b26"
    fg: "#c0caf5"
    accent: "#7aa2f7"

dvm apply -f my-custom-theme.yaml

# Export an existing theme to customize
dvm get nvim theme coolnight-ocean -o yaml > my-ocean.yaml
# Edit my-ocean.yaml, then:
dvm apply -f my-ocean.yaml

User-defined themes with the same name as a built-in theme override the library version.
