### Adding a New Scheme to Base16 Registry (YAML)

Source: https://context7.com/chriskempson/base16-schemes-source/llms.txt

This example demonstrates how to add a new scheme to the `list.yaml` file. New entries must follow the `base16-[scheme-name]-scheme` naming convention for repositories and be inserted alphabetically into the list.

```yaml
# Example: Adding a new scheme called "midnight"
# Repository must be named: base16-midnight-scheme
# Add entry in alphabetical position in list.yaml:

materia: https://github.com/Defman21/base16-materia
midnight: https://github.com/yourusername/base16-midnight-scheme  # New entry
nebula: https://github.com/Misterio77/base16-nebula-scheme
```

### Parse Base16 Scheme Registry with Python

Source: https://context7.com/chriskempson/base16-schemes-source/llms.txt

This Python script fetches the `list.yaml` registry, parses it using `PyYAML`, and iterates through each scheme. It demonstrates how to extract scheme names and repository URLs, and construct raw URLs for scheme definition files.

```python
import yaml
import requests

# Fetch the scheme list from the repository
response = requests.get(
    "https://raw.githubusercontent.com/chriskempson/base16-schemes-source/main/list.yaml"
)
schemes = yaml.safe_load(response.text)

# Iterate through all available schemes
for scheme_name, repo_url in schemes.items():
    print(f"Scheme: {scheme_name}")
    print(f"Repository: {repo_url}")

    # Convert GitHub URL to raw YAML URL for scheme files
    # Each scheme repo contains .yaml files with color definitions
    raw_base = repo_url.replace("github.com", "raw.githubusercontent.com") + "/main/"
    print(f"Raw URL base: {raw_base}")
    print("---")

# Output:
# Scheme: default
# Repository: https://github.com/chriskempson/base16-default-schemes
# Raw URL base: https://raw.githubusercontent.com/chriskempson/base16-default-schemes/main/
# ---
# Scheme: apprentice
# Repository: https://github.com/casonadams/base16-apprentice-scheme
# ...

### Parse Base16 Scheme Registry with Shell

Source: https://context7.com/chriskempson/base16-schemes-source/llms.txt

This shell script provides a concise way to download and parse the `list.yaml` registry. It filters out comments and empty lines, then iterates through scheme entries to display their names and URLs, with an option to clone repositories. It also includes a command to count the total number of registered schemes.

```bash
# Download and parse the scheme list
curl -s https://raw.githubusercontent.com/chriskempson/base16-schemes-source/main/list.yaml | \
  grep -v "^#" | \
  grep -v "^$" | \
  while IFS=': ' read -r name url; do
    echo "Fetching scheme: $name from $url"
    # Clone each scheme repository
    # git clone "$url" "schemes/$name"
  done

# Count total schemes
curl -s https://raw.githubusercontent.com/chriskempson/base16-schemes-source/main/list.yaml | \
  grep -v "^#" | grep -v "^$" | wc -l
# Output: 76
```

### Base16 Scheme Registry Format (YAML)

Source: https://context7.com/chriskempson/base16-schemes-source/llms.txt

The `list.yaml` file serves as the core registry, mapping scheme names to their respective GitHub repository URLs. This format is directly parsed by Base16 builders to discover available color schemes.

```yaml
# Official Base16 Schemes
default: https://github.com/chriskempson/base16-default-schemes

# Community Contributed Schemes - alphabetically ordered
apprentice: https://github.com/casonadams/base16-apprentice-scheme
atelier: https://github.com/atelierbram/base16-atelier-schemes
atlas: https://github.com/ajlende/base16-atlas-scheme
dracula: https://github.com/dracula/base16-dracula-scheme
gruvbox: https://github.com/dawikur/base16-gruvbox-scheme
nord: https://github.com/spejamchr/base16-nord-scheme
solarized: https://github.com/aramisgithub/base16-solarized-scheme
```
