## Installation

The tool is
[written in Rust](https://crates.io/crates/preserves-tools).
[Install `cargo`.](https://doc.rust-lang.org/cargo/getting-started/installation.html)
Then, `cargo install preserves-tools`.

## Subcommands

The tool includes three subcommands.

### `preserves-tool convert`, `preserves-tool`

This is the main tool, and is also the default if no subcommand is
explicitly specified. It can

 - translate between the various Preserves text and binary document
   syntaxes;
 - strip annotations;
 - pretty-print; and
 - break down and filter documents using [preserves path](..{% link preserves-path.md %}) selectors.

#### Usage

    preserves-tool-convert

    USAGE:
        preserves-tool convert [FLAGS] [OPTIONS]

    OPTIONS:
            --bundle <filename>


        -c, --commas <COMMAS>
                [default: none] [possible values: none, separating, terminating]

            --collect


            --escape-spaces


        -h, --help
                Print help information

        -i, --input-format <INPUT_FORMAT>
                [default: auto-detect] [possible values: auto-detect, text, binary]

            --indent <on/off>
                [default: on] [possible values: disabled, enabled]

            --limit <LIMIT>


        -o, --output-format <OUTPUT_FORMAT>
                [default: text] [possible values: text, binary, unquoted]

            --read-annotations <on/off>
                [default: on] [possible values: disabled, enabled]

            --select <SELECT_EXPR>
                [default: *]

            --select-output <SELECT_OUTPUT>
                [default: sequence] [possible values: sequence, set]

            --write-annotations <on/off>
                [default: on] [possible values: disabled, enabled]

### `preserves-tool quote`

This subcommand reads chunks from standard input and outputs each one
as a Preserves `String`, `Symbol`, or `ByteString` using either the
text or binary Preserves surface syntax.

This is useful when writing shell scripts that interact with other
programs using Preserves as an interchange format.

It defaults to taking the entirety of standard input as a single large
chunk, but it can also work with newline- or `nul`-delimited chunks.
