ngrv\n\n[![CI][ci-badge]][ci-url]\n[![Version][version-badge]][version-url]\n![MSRV][msrv-badge]\n![License][license-badge]\n\n**ngrv** (**n**a**g**a**r**e **v**iewer, 流れビューアー) is a terminal-based\ntool for monitoring the progress of data through a pipeline written in [Rust].\nIt is inspired by [`pv(1)`] and can be used for similar purposes, but is not\nintended as a drop-in replacement for it.\n\n![Demo animation](assets/demo.gif)\n\n## Installation\n\n### From source\n\n```sh\ncargo install ngrv\n```\n\n### From binaries\n\nThe [release page] contains pre-built binaries for Linux, macOS and Windows.\n\n### How to build\n\nPlease see [BUILD.adoc].\n\n## Usage\n\n### Basic usage\n\nTo watch the progress of compressing a `.gz` file:\n\n```sh\nngrv archive.tar | gzip \u003e archive.tar.gz\n```\n\nA similar example that read a `.tar` archive from standard input:\n\n```sh\ncat archive.tar | ngrv -s 4GiB | gzip \u003e archive.tar.gz\n```\n\n\u003e [!TIP]\n\u003e If any inputs are not files or the size of the file cannot be queried, the\n\u003e progress bar will not be shown unless `-s` is specified.\n\n### Generate shell completion\n\n`--generate-completion` option generates shell completions to standard output.\n\nThe following shells are supported:\n\n- `bash`\n- `elvish`\n- `fish`\n- `nushell`\n- `powershell`\n- `zsh`\n\nExample:\n\n```sh\nngrv --generate-completion bash \u003e ngrv.bash\n```\n\n## Command-line options\n\nPlease see the following:\n\n- [`ngrv(1)`]\n\n## Source code\n\nThe upstream repository is available at\n\u003chttps://github.com/sorairolake/ngrv.git\u003e.\n\n## Changelog\n\nPlease see [CHANGELOG.adoc].\n\n## Contributing\n\nPlease see [CONTRIBUTING.adoc].\n\n## Acknowledgment\n\nThis program is
