#### Bring the power of Clap to shell scripts

Claptrap is a tool that allows you to parse complex command line arguments in shell scripts using a declarative
specification.

Features:

Claptrap brings the full power of Clap command line parsing to shell scripts. Command line interface specifications can
be declared in `toml`, `yaml` or `json` and used as standalone files or embedded directly in scripts.

Claptrap Supports `bash`, `zsh`, `fish` and `PowerShell` scripts and can run on Linux, BSD, macOS, and Windows. Claptrap
can also automatically generate shell completions, man pages, markdown documentation and template scripts.

See the [documentation](<https://claptrap.sh>) for more details.

Example:

```
#!/usr/bin/env bash

set -euo pipefail

eval "$(claptrap --spec - -- "$@" <<'SPEC'
name = "hello"
[args]
name = { short = 'n', long = "name", default-value = "world" }
SPEC
)"

echo "hello, ${claptrap_name}!"
```
