parameter-types

Parameter Types Example

This example demonstrates all parameter types available in the glazed framework.

Usage

# Build the example
go build -o parameter-types .

# Show help to see all available parameters
./parameter-types --help

# Run with default values
./parameter-types

# Test basic types
./parameter-types \
  --string-param "hello world" \
  --secret-param "my-secret" \
  --integer-param 100 \
  --float-param 2.71828 \
  --bool-param=false \
  --date-param "2024-12-25" \
  --choice-param option2

# Test list types
./parameter-types \
  --string-list-param item1,item2,item3 \
  --integer-list-param 10,20,30 \
  --float-list-param 1.1,2.2,3.3 \
  --choice-list-param red,green

# Test file types
./parameter-types \
  --file-param sample.json \
  --file-list-param sample.json,sample.yaml \
  --string-from-file-param sample-text.txt \
  --string-list-from-file-param sample-lines.txt \
  --object-from-file-param sample.json \
  --object-list-from-file-param sample-list.json

# Test key-value type
./parameter-types \
  --key-value-param key1:value1,key2:value2

# Load key-value from file
./parameter-types \
  --key-value-param @config.yaml

Parameter Types Demonstrated

Basic Types

• string: Simple text values
• secret: Text values that are masked when displayed (***)
• integer: Whole numbers
• float: Decimal numbers
• bool: Boolean true/false values
• date: Date/time values (RFC3339 or natural language)
• choice: Single value from predefined options

List Types

• string-list: Multiple text values
• integer-list: Multiple integers
• float-list: Multiple decimal numbers
• choice-list: Multiple values from predefined options

File Types

• file: Load file with metadata (path, size, type, etc.)
• file-list: Load multiple files with metadata
• string-from-file: Load file content as a single string
• string-from-files: Load and concatenate multiple files as string
• string-list-from-file: Load file lines as string list
• string-list-from-files: Load lines from multiple files as string list
• object-from-file: Parse JSON/YAML file as object
• object-list-from-file: Parse JSON/YAML file as object list
• object-list-from-files: Parse multiple files and merge object lists

Key-Value Type

• key-value: Map of key-value pairs (key:value format or @file)

Sample Files

• sample.json - JSON object for testing object parameters
• sample.yaml - YAML data for testing YAML parsing
• sample-list.json - JSON array for testing list parameters
• sample-text.txt - Multi-line text for string parameters
• sample-lines.txt - Line-by-line text for list parameters
• config.yaml - Configuration file for key-value parameters

Output

The program displays all parsed parameter values in a structured format, demonstrating how each type is processed and what the final values look like.

Note that secret parameters will show as *** in the output to protect sensitive data.
