Scwrypts (Wryn + Scripts)

Scwrypts is a friendly CLI / API for quickly running sandboxed scripts in the terminal.

In modern developer / dev-ops workflows, scripts require a complex configurations. Without a better solution, the developer is cursed to copy lines-upon-lines of variables into terminals, create random text artifacts, or maybe even commit secure credentials into source. Scwrypts leverages ZSH to give hot-key access to run scripts in such environments.

Major Version Upgrade Notice

Please refer to Version 3 to Version 4 Upgrade Path when upgrading from scwrypts v3 to scwrypts v4!

Dependencies

Due to the wide variety of resources used by scripting libraries, the user is expected to manually resolve dependencies. Dependencies are lazy-loaded, and more information can be found by command error messages or in the appropriate README.

Because Scwrypts relies on Scwrypts (see Meta Scwrypts), zsh must be installed and junegunn/fzf must be available on your PATH.

Usage

Install Scwrypts by cloning this repository and sourcing scwrypts.plugin.zsh in your zshrc. You can now run Scwrypts using the ZLE hotkey bound to SCWRYPTS_SHORTCUT (default CTRL + W).

% cd <path-to-cloned-repo>
% echo "source $(pwd)/scwrypts.plugin.zsh >> $HOME/.zshrc"

Check out Meta Scwrypts to quickly set up environments and adjust configuration.

No Install / API Usage

Alternatively, the scwrypts API can be used directly:

./scwrypts [--env environment-name] (...script-name-patterns...) [-- ...passthrough arguments... ]

Given one or more script patterns, Scwrypts will filter the commands by pattern conjunction. If only one command is found which matches the pattern(s), it will immediately begin execution. If multiple commands match, the user will be prompted to select from the filtered list. Of course, if no commands match, Scwrypts will exit with an error.

Given no script patterns, Scwrypts becomes an interactive CLI, prompting the user to select a command.

After determining which script to run, if no environment has been specified, Scwrypts prompts the user to choose one.

Using in CI/CD or Automated Workflows

Set environment variable CI=true (and use the no install method) to run in an automated pipeline. There are a few notable changes to this runtime:

• The Scwrypts sandbox environment will not load. All variables will be read from context.
• User yes/no prompts will always be YES
• Other user input will default to an empty string
• Logs will not be captured
• Setting the environment variable SCWRYPTS_GROUP_LOADER__[a-z_]\+ will source the file indicated in the variable (this allows custom groups without needing to modify the config.zsh directly)
  • In GitHub actions, *.scwrypts.zsh groups are detected automatically from the $GITHUB_WORKSPACE; set SCWRYPTS_GITHUB_NO_AUTOLOAD=true to disable
