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}!"

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install claptrap, simply use the following command:
sudo snap install claptrap
Browse and find snaps from the convenience of your desktop using the snap store snap.
