= Build and Install

This document describes how to build and install *RSHash* from source code.

== Prerequisites

.To build *RSHash*, you need to have the following dependencies installed
* https://doc.rust-lang.org/stable/cargo/[Cargo] (v1.56.0 or later)

.To build man pages, you need to have the following additional dependencies installed
* https://asciidoctor.org/[Asciidoctor]

== Building and installing from source

First, either download the source archive or clone the https://github.com/sorairolake/rshash[Git repository].

.To clone the Git repository
[source, shell]
----
$ git clone https://github.com/sorairolake/rshash.git
$ cd rshash
----

.To build a package
[source, shell]
----
$ cargo build --release
----

NOTE: If Asciidoctor is available, man pages are generated.
Run `fd -I . target/{asterisk}/build/rshash-{asterisk}/out` to find the generated.

Now an executable is generated in `$CARGO_TARGET_DIR/release`, so copy this wherever you like.

.To generate shell completion
[source, shell]
----
# Output to stdout.
$ cargo run -- --generate-completion <SHELL>

# Output to a file.
$ cargo run -- --generate-completion <SHELL> -o <OUT_DIR>
