chmln/sd

This system is a command-line search-and-replace tool implemented in Rust, designed for efficient text processing. It features line-by-line streaming to minimize memory usage, supports in-place file editing, and allows reading from or writing to standard input. The project is structured as a Cargo workspace with automated generation of shell completions and documentation.

The xtask tool now includes a 'gen' command that automatically generates shell completion scripts and a man page for the sd CLI. This change moves the responsibility of creating these static assets from manual processes to an automated build step, ensuring that documentation and shell integrations are always up-to-date with the current command-line interface definitions.

The sd-cli package now provides a command-line tool for search-and-replace operations. It defaults to line-by-line processing for memory efficiency, supports in-place file modification, and allows reading from or writing to standard input. Users can control behavior via flags such as \-p\ for preview mode, \-F\ for literal string matching, and \-A\ to process files across line boundaries.

The application's internal structure has been completely overhauled to improve efficiency and maintainability. The previous monolithic modules for application logic, error handling, and input streaming (app.rs, error.rs, input.rs, main.rs) have been removed and replaced with a new, modular implementation. This change introduces a more efficient pipeline for multi-file replacements, switches the CLI argument parsing library from structopt to clap v4, and adopts a custom error type for better error management. Users will experience these changes as a more robust and performant replacement tool, although the specific command-line interface details are defined in other parts of the codebase.

The tool now processes files line-by-line by default, streaming content without loading entire files into memory. This change improves performance and reduces memory consumption when handling large files, while maintaining the same replacement logic and output behavior for users.

sd · high confidence

The project has been restructured into a Cargo workspace containing the core library (sd), the CLI binary (sd-cli), and a build task runner (xtask). This change upgrades the Rust edition to 2024 and bumps the minimum supported Rust version to 1.86.0. Key dependencies have been updated, including the CLI argument parser (clap) to version 4.4.6 and the regex engine to 1.10.2, while the package name and repository URLs have been updated to reflect the 'sd' project identity.

(dependencies) · high confidence

The generated assets in the gen directory have been updated to reflect the sd 1.0.0 release. This includes new shell completion scripts for Zsh, PowerShell, Bash, Elvish, and Fish, as well as a new man page (sd.1). These files document the current command-line interface, including options such as --preview, --fixed-strings, --max-replacements, --flags, and --across, ensuring that users receive accurate tab-completion and documentation for the tool's features.
