qsv-tabwriter 2.0.0

NOTE: qsv-tabwriter is a renamed fork of tabwriter with the following changes:

• It implements LeftTabEnd and LeftFwf alignment
• updated to 2024 edition
• applied numerous clippy lint suggestions
• is BufWriter-backed to minimize syscalls

tabwriter is a crate that implements elastic tabstops. It provides both a library for wrapping Rust Writers and a small program that exposes the same functionality at the command line.

Dual-licensed under MIT or the UNLICENSE.

Simple example of library

use std::io::Write;

use qsv_tabwriter::TabWriter;

let mut tw = TabWriter::new(vec![]);
tw.write_all(b"
Bruce Springsteen\tBorn to Run
Bob Seger\tNight Moves
Metallica\tBlack
The Boss\tDarkness on the Edge of Town
").unwrap();
tw.flush().unwrap();

let written = String::from_utf8(tw.into_inner().unwrap()).unwrap();

assert_eq!(&written, "
Bruce Springsteen  Born to Run
Bob Seger          Night Moves
Metallica          Black
The Boss           Darkness on the Edge of Town
");

Documentation

The API is fully documented with some examples: https://docs.rs/qsv-tabwriter/latest/tabwriter/.

Installation

This crate works with Cargo. Assuming you have Rust and Cargo installed, simply check out the source and run tests:

git clone git://github.com/jqnatividad/qsv-tabwriter
cd qsv-tabwriter
cargo test

You can also add qsv-tabwriter as a dependency to your project's Cargo.toml:

[dependencies]
qsv-tabwriter = "2"

Dealing with ANSI escape codes

If you want tabwriter to be aware of ANSI escape codes, then you should enable the TabWriter::ansi option. Previously this was done by enabling the crate feature ansi_formatting, but that feature is now deprecated. (If you use it, then TabWriter::ansi will be automatically enabled for you. Otherwise it is disabled by default.)

Minimum Rust version policy

This crate's minimum supported rustc version is 1.90.0.

The current policy is to use the latest Rust stable.
