CLI Arguments

CLI arguments take precedence over configuration file options.

Options

Option Short Description Default Example
--reporter -r Output format: table, json table --reporter json
--exclude -e Exclude path patterns (can be used multiple times) - --exclude "*.test.ts"
--config -c Configuration file path - --config techscan.json
--version Display techscan version - --version

Examples

# Scan languages with table output (default)
techscan lang ./project

# Scan languages with JSON output
techscan lang ./project --reporter json

# Scan languages with exclude specific file patterns
techscan lang ./project --exclude "*.test.ts" --exclude "node_modules"

# Multiple excludes with short option
techscan lang ./project -e "*.test.ts" -e "*.spec.ts" -e "dist"

# Using configuration file
techscan lang ./project --config techscan.json

# Configuration file with CLI option override
techscan lang ./project --config techscan.json --exclude "node_modules"

CLI Configuration File

techscan supports configuration files in JSON (.json, .json5), YAML (.yaml, .yml), and TOML (.toml) formats to set default options.

Options

Setting Type Description Default Example
exclude Array of strings File patterns to exclude from analysis [] (none) ["*.test.*", "dist"]
reporter String Output format ("table" or "json") "table" "json"

Examples

JSON Format
{
  "exclude": ["*.test.*", "dist"],
  "reporter": "json"
}
YAML Format
