Day ??? of learning go. Building cli apps

Why cli??

I have always had a preference for command line interface (CLI) and terminal user interface (TUI) tools over their graphical user interface (GUI) counterparts. This project, aptly named "Phraser" (no apologies for the poor naming), is a command line application designed to manage wallet seed phrases for crypto wallets. I developed this application to create a more convenient way to manage the seed phrases for my crypto wallets.
It creates a directory and stores the phrases in encrypted JSON files. You can then move the JSON files and store them anywhere you want.

Why go?

To enhance my skills, I chose to rewrite a project I had previously written in Python using Go. Unlike the Python version, which requires a multitude of dependencies to be installed, the Go version can be compiled into a single binary, making it more portable and less cumbersome. Additionally, Go is known for its blazing speed(I couldn't resist:))

Tool used

Go v1.22.5(of course)
Cobra-cli

Installation

You can find a precompiled binary on the releases page of the GitHub repository(link at end of article).

Manual Installation

If you prefer, you can clone the repository and install the dependencies to test it out.
The instructions are in the Readme in the GitHub repository, but I will still highlight them here.

Usage

Phraser is easy to use with a set of straightforward commands. Here's a basic overview:

   phraser [command] [flags]

Commands

completion: Generate the autocompletion script for the specified shell.
create: Creates a wallet in your store.
gendoc: Generate Markdown documentation for all commands.
get: Retrieves data stored in a wallet.
init: Initializes a store.

Options

  -a, --amount int      amount of phrases to be inputted
  -h, --help            help for phraser
  -s, --store string    name of the store to access
  -t, --toggle          Help message for toggle
  -w, --wallet string   name of the wallet to be created

Examples

Initialize a new store:

   phraser init --store myStore

Create a new wallet:

   phraser create --store myStore --wallet myWallet --amount 12

Retrieve a wallet's seed phrase:

   phraser get --store --wallet myWallet

Conclusion

This project taught me a lot about Go-like encryption/decryption, file handling, and also the cobra-cli for building CLI apps. Any feedback and corrections are appreciated.

Implementing Mutexes and Locks in Go for Thread SafetyMay 05, 2025 am 12:18 AM

In Go, using mutexes and locks is the key to ensuring thread safety. 1) Use sync.Mutex for mutually exclusive access, 2) Use sync.RWMutex for read and write operations, 3) Use atomic operations for performance optimization. Mastering these tools and their usage skills is essential to writing efficient and reliable concurrent programs.

Benchmarking and Profiling Concurrent Go CodeMay 05, 2025 am 12:18 AM

How to optimize the performance of concurrent Go code? Use Go's built-in tools such as getest, gobench, and pprof for benchmarking and performance analysis. 1) Use the testing package to write benchmarks to evaluate the execution speed of concurrent functions. 2) Use the pprof tool to perform performance analysis and identify bottlenecks in the program. 3) Adjust the garbage collection settings to reduce its impact on performance. 4) Optimize channel operation and limit the number of goroutines to improve efficiency. Through continuous benchmarking and performance analysis, the performance of concurrent Go code can be effectively improved.

Error Handling in Concurrent Go Programs: Avoiding Common PitfallsMay 05, 2025 am 12:17 AM

The common pitfalls of error handling in concurrent Go programs include: 1. Ensure error propagation, 2. Processing timeout, 3. Aggregation errors, 4. Use context management, 5. Error wrapping, 6. Logging, 7. Testing. These strategies help to effectively handle errors in concurrent environments.

Go Error Handling: Best Practices and PatternsMay 04, 2025 am 12:19 AM

In Go programming, ways to effectively manage errors include: 1) using error values instead of exceptions, 2) using error wrapping techniques, 3) defining custom error types, 4) reusing error values for performance, 5) using panic and recovery with caution, 6) ensuring that error messages are clear and consistent, 7) recording error handling strategies, 8) treating errors as first-class citizens, 9) using error channels to handle asynchronous errors. These practices and patterns help write more robust, maintainable and efficient code.

How do you implement concurrency in Go?May 04, 2025 am 12:13 AM

Implementing concurrency in Go can be achieved by using goroutines and channels. 1) Use goroutines to perform tasks in parallel, such as enjoying music and observing friends at the same time in the example. 2) Securely transfer data between goroutines through channels, such as producer and consumer models. 3) Avoid excessive use of goroutines and deadlocks, and design the system reasonably to optimize concurrent programs.
