Config Command

The viben config command provides git-style configuration management. It allows you to read, write, list, and edit configuration values using familiar syntax.

Command Overview

viben config <subcommand> [options]

Subcommands:
  get       Get a configuration value
  set       Set a configuration value
  list      List all configuration values
  edit      Open configuration file in editor
  unset     Remove a configuration value

Reading Configuration

Get a Single Value

viben config get <key>

Examples:

# Get the default editor
viben config get settings.editor
# Output: code

# Get global setting
viben config get --global settings.pager
# Output: less

# Get from workspace
viben config get --workspace mcp.enabled
# Output: ["filesystem", "git"]

Key Format

Configuration keys use dot notation to access nested values:

Key	Description
settings.editor	Default editor
settings.pager	Output pager
settings.color	Color mode
mcp.enabled	Enabled MCP servers
mcp.disabled	Disabled MCP servers
skills.enabled	Enabled skills

For array access, use bracket notation:

# Get first enabled MCP
viben config get mcp.enabled[0]

# Get second agent reference
viben config get agents[1]

Writing Configuration

Set a Value

viben config set <key> <value>

Examples:

# Set editor
viben config set settings.editor vim

# Set pager globally
viben config set --global settings.pager less

# Set color mode
viben config set settings.color always

Setting Complex Values

For arrays and objects, use JSON format:

# Set enabled MCP servers
viben config set mcp.enabled '["filesystem", "git", "browser"]'

# Set multiple skills
viben config set skills.enabled '["code-review", "commit", "test-runner"]'

Scope Options

Option	Description
--global, -g	Write to global config (~/.viben/config.yaml)
--workspace	Write to workspace config (.viben/config.yaml)

# Set in global config
viben config set --global settings.editor code

# Set in workspace config
viben config set --workspace mcp.enabled '["filesystem"]'

Listing Configuration

List All Values

viben config list

Output:

settings.editor=code
settings.pager=less
settings.color=auto
mcp.enabled=["filesystem","git"]
mcp.disabled=["browser"]
skills.enabled=["code-review","commit"]

Show Configuration Origin

Use --show-origin to see where each value comes from:

viben config list --show-origin

Output:

global    settings.editor=code
global    settings.pager=less
workspace settings.color=always
workspace mcp.enabled=["filesystem","git","browser"]
global    mcp.disabled=["browser"]
global    skills.enabled=["code-review","commit"]

Scope-Specific Listing

# List only global configuration
viben config list --global

# List only workspace configuration
viben config list --workspace

Editing Configuration

Open in Editor

viben config edit

This opens the configuration file in your default editor (set by settings.editor or $EDITOR).

Edit Specific Scope

# Edit global config
viben config edit --global

# Edit workspace config
viben config edit --workspace

Editor Priority

The editor is selected in this order:

1. settings.editor from config
2. $VISUAL environment variable
3. $EDITOR environment variable
4. vi (fallback)

Removing Configuration

Unset a Value

viben config unset <key>

Examples:

# Remove a setting
viben config unset settings.pager

# Remove from global config
viben config unset --global mcp.disabled

注意

Unsetting a workspace value reveals the underlying global value. To truly disable something at workspace level, set it to an empty value instead.

JSON Output

All config commands support --json for structured output:

viben config list --json

Output:

{
  "success": true,
  "data": {
    "settings": {
      "editor": "code",
      "pager": "less",
      "color": "auto"
    },
    "mcp": {
      "enabled": ["filesystem", "git"],
      "disabled": ["browser"]
    },
    "skills": {
      "enabled": ["code-review", "commit"]
    }
  }
}

viben config get settings.editor --json

Output:

{
  "success": true,
  "data": {
    "key": "settings.editor",
    "value": "code",
    "origin": "global"
  }
}

Common Use Cases

Initial Setup

# Set your preferred editor
viben config set --global settings.editor code

# Enable color output
viben config set --global settings.color always

# Set default MCP servers
viben config set --global mcp.enabled '["filesystem", "git"]'

Per-Project Configuration

# Initialize workspace
viben init

# Enable additional MCP for this project
viben config set --workspace mcp.enabled '["filesystem", "git", "browser"]'

# Disable certain skills for this project
viben config set --workspace skills.disabled '["commit"]'

Debugging Configuration Issues

# See all config with origins
viben config list --show-origin

# Check effective value
viben config get mcp.enabled

# Verify scope detection
viben config list --json | jq '.data'

Error Handling

Invalid Key

viben config get nonexistent.key

Output:

{
  "success": false,
  "error": {
    "code": "KEY_NOT_FOUND",
    "message": "Configuration key 'nonexistent.key' not found"
  }
}

Invalid Value Format

viben config set mcp.enabled "not-valid-json"

Output:

{
  "success": false,
  "error": {
    "code": "INVALID_VALUE",
    "message": "Value for 'mcp.enabled' must be a valid JSON array"
  }
}
