CLI output formatting utilities.

This crate provides utilities for building command-line applications, including output processing, formatting, and other CLI-specific helpers.

Modules

• output - Process command output (head/tail filtering, width truncation, stream merging)
• help - Typed, configurable CLI help text renderer (CliHelpTemplate, CliHelpStyle, CliHelpData)

Architecture

This crate focuses on CLI-application-specific functionality. For general-purpose string and ANSI manipulation, use strs_tools instead.

Distinction:

• strs_tools: Generic string/ANSI utilities (any application)
• cli_fmt: CLI-specific helpers (command-line tools only)

Examples

# #[ cfg( feature = "output" ) ]
# {
use cli_fmt::output::*;

let config = OutputConfig::default()
  .with_head( 10 )
  .with_width( 80 );

let result = process_output( "stdout text", "stderr text", &config );
println!( "{}", result.content );
# }
