A Rust crate implementing elastic tabstops for aligning tabular data in text output.
tabwriter is a Rust crate that implements elastic tabstops for aligning tabular data in text output. It provides both a library for programmatically formatting text in Rust applications and a command-line utility for shell usage. The tool dynamically adjusts column widths based on content, solving alignment issues in terminal tables or generated reports.
Rust developers working with text-based output, such as CLI tools, log formatters, or data presentation libraries that require clean tabular alignment.
Developers choose tabwriter for its efficient implementation of elastic tabstops, which offers more flexible and readable text alignment compared to fixed-width tabs. Its dual library/CLI design and ANSI escape code support make it versatile for both programmatic and interactive use cases.

Implements elastic tabstops to adjust column widths based on content, providing flexible and readable alignment, as shown in the library example with artist and song names.
Offers both a Rust library for programmatic use and a standalone command-line tool, making it suitable for embedding in applications or shell pipelines, as highlighted in the simple examples.
Can handle ANSI codes to preserve text colors and formatting in aligned output, though it requires enabling the TabWriter::ansi option, as noted in the README section on dealing with ANSI codes.
Focuses on simplicity with minimal dependencies, prioritizing correctness and performance for text formatting tasks, as stated in the project philosophy.
Only aligns text; lacks built-in support for table headers, borders, or advanced styling, which may require additional tools for comprehensive table formatting.
As a Rust crate, it cannot be directly used in projects written in other languages without integration efforts, limiting its applicability in polyglot environments.
ANSI code handling is not enabled by default and requires manual configuration via TabWriter::ansi, which can lead to formatting issues if overlooked in colored output setups.
