lazer-rs

Console printer with a fluent API, written in Rust.

lazer

Lazer is a utility for printing to the console using a fluent API. Ported to Rust from the original TypeScript package.

Description

Lazer helps you build, format and print complex messages to the console using an expressive fluent API.

Usage

Simple Example

main.rs

```rust use lazer::{lazer};

fn main() { lazer() .print("Hello,") .printspace() .printgreen("Green World") .print_ln("!"); } ```

```bash $ cargo run Hello, Green World!

```

Complex Example

```typescript use lazer::{lazer};

fn main() { let remoteaddr = "127.0.0.1"; let method = "GET"; let path = "/a/really/really/really/long/path/here"; let status = 200; let timems = 20; let sizebytesstring = "1.10kB";

lazer()
    .print("[").print_utc_time().print("]")
    .print_space(1).print("-").print_space(1)
    .print_pad_right(remote_addr, 15, "_")
    .print_space(2)
    .print_pad_right(method, 4, "_")
    .print_space(2)
    .print_pad_right(path, 20, "_")
    .print_space(2)
    .iff(status >= 200 && status < 300)
        .print_green(&status.to_string())
    .eliff(status >= 300 && status < 400)
        .print_yellow(&status.to_string())
    .eliff(status >= 400)
        .print_red(&status.to_string())
    .end()
    .print_space(2)
    .print_pad_right(&format!("{}ms", time_ms), 6, "_")
    .print_space(2)
    .print_ln(size_bytes_string);

} ```

```bash $ deno run example.ts [Tue, 11 May 2021 17:25:18 +0000] - 127.0.0.1_ GET_ /a/really/really/r+18 200 20ms__ 1.10kB

```

Buffering Example

```typescript import { lazer } from "https://deno.land/x/lazer/mod.ts"

const getLinePrefix = () => { return lazer().buffer() .printyellow('[').printyellow("Line Prefix").printyellow(']') .printspace().print("-").printspace() .printyellow('[').setcoloryellow().printutctime().printyellow(']') .printspace().print("-").print_space() .return(); }

lazer() .print(getLinePrefix()) .printyellowln("This is a prefixed line of text output");

lazer() .print(getLinePrefix()) .printyellowln("This is another prefixed line of text output"); ```

```bash $ deno run example.ts [Line Prefix] - [Mon, 10 May 2021 16:31:29 GMT] - This is a prefixed line of text output [Line Prefix] - [Mon, 10 May 2021 16:31:29 GMT] - This is another prefixed line of text output

```

Buffer Aliasing Example

```typescript import { lazer } from "https://deno.land/x/lazer/mod.ts"

lazer().buffer() .setcolorred().print_ln("Some red output to buffer") .store('i am an alias');

lazer().buffer() .load('i am an alias') .print_b(); ```

```bash $ deno run example.ts Some red output to buffer

```

Supported Platforms
