badger-cli

badger-cli is a simple command-line interface for interacting with Badger DB, a fast key-value database written in Go.

Features

• Connect to an existing Badger DB
• Get, set, and delete key-value pairs
• List keys with optional glob pattern matching

Installation

To install badger-cli, make sure you have Go installed on your system, then run:

go install github.com/lovromazgon/badger-cli

Usage

Run the CLI by providing the path to your Badger database:

badger-cli /path/to/your/badger/db

Once the CLI is running, you can use the following commands:

• get <key>: Retrieve the value for a given key
• set <key> <value>: Set a value for a given key
• delete <key>: Delete a key-value pair
• list [pattern]: List all keys, optionally filtered by a glob pattern
• exit: Exit the CLI

Examples

set mykey myvalue
Value set successfully

get mykey
myvalue

list my*
mykey

delete mykey
Value deleted successfully

list
No matching keys found

exit

Glob Pattern Matching

The list command supports glob pattern matching:

• *: Matches any sequence of characters
• ?: Matches any single character
• [abc]: Matches any character in the set
• [a-z]: Matches any character in the range

Examples:

• list app_*: Lists all keys starting with "app_"
• list *_config: Lists all keys ending with "_config"
• list user_??: Lists all keys starting with "user_" followed by exactly two characters

Acknowledgements

The initial version of this CLI was developed with assistance from an AI language model. The code has since been modified and expanded.
