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}!"
