# ZSH Utilities
|
|
|
|
A shell-scripting utilities module made for ZSH.
|
|
This module is definitely a major component of Scwrypts, but is also standalone and can be sourced by any ZSH script to utilize (almost) all of the features.
|
|
|
|
## Usage
|
|
Import `utils.module.zsh` to activate all of the features.
|
|
Doing so will *also* check for path dependencies and required environment variables (see [Dependencies](#dependencies) and [Environment](#environment) below).
|
|
|
|
|
|
```shell
|
|
#!/bin/zsh
|
|
source ./path/to/utils.plugin.zsh
|
|
__SUCCESS 'ZSH utilities online!'
|
|
```
|
|
|
|
Checkout [io](./io.zsh) and [os](./os.zsh) for available simple functions.
|
|
|
|
### Dependencies
|
|
Ensures dependent programs are available for execution.
|
|
Specify a simple name to check the current `PATH`, or give a fully-qualified path for arbitrary dependency inclusion.
|
|
|
|
Include a dependency by adding to the `_DEPENDENCIES` array.
|
|
*Always using `+=` makes your dependencies extensible to other scripts :)*
|
|
|
|
If any dependencies are missing, `source utils.module.zsh` will return an error code and count the number of missing dependencies in the variable `DEP_ERROR_COUNT`.
|
|
|
|
```shell
|
|
#!/bin/zsh
|
|
_DEPENDENCIES+=(
|
|
path-executable-1
|
|
path-executable-2
|
|
/path/to/arbitrary/program
|
|
)
|
|
source ./path/to/utils.plugin.zsh
|
|
echo "missing $DEP_ERROR required dependencies"
|
|
```
|
|
|
|
### Environment
|
|
Similar to [Dependencies](#dependencies), `environment.zsh` ensures a list of environment variables are *set to non-empty values*.
|
|
|
|
Include an environment variable by adding to the `_REQUIRED_ENV` array.
|
|
*Something something use `+=` here too ;)*
|
|
|
|
If any environment variables are missing, `source utils.module.zsh` will return an error code and count the number of missing variables in `ENV_ERROR_COUNT`.
|
|
|
|
Missing environment variables will be added to the environment template (*exclusive to Scwrypts*).
|
|
|
|
```shell
|
|
#!/bin/zsh
|
|
_REQUIRED_ENV+=(
|
|
AWS_PROFILE
|
|
AWS_REGION
|
|
)
|
|
source ./path/to/utils.plugin.zsh
|
|
echo "missing $ENV_ERROR_COUNT required environment variables"
|
|
```
