Testing
Create a wev.yml configuration file suitable for your plugin:
# Invoke the wev-ask plugin to set the DEFAULT_FOO environment variable:
DEFAULT_FOO:
plugin:
id: wev-ask
# Invoke the wev-ask plugin to set the LOWER_FOO environment variable:
LOWER_FOO:
plugin:
id: wev-ask
force_case: lower
# Invoke the wev-ask plugin to set the UPPER_FOO environment variable:
UPPER_FOO:
plugin:
id: wev-ask
force_case: upper
Install your plugin:
pipenv install . --skip-lock
Verify the plugin is installed by generating an execution plan:
wev --explain
Warning
If you get an error about your plugin not being installed then you're probably running a global installation of wev rather than the one in your virtual environment.
Either uninstall the global installation, or install your plugin globally.
wev (1.1.1) execution plan generated at 2021-01-17 13:44:41:
1. DEFAULT_FOO will be resolved by the wev-ask plugin.
You will be prompted to enter a special value, which will be cached for 30 seconds.
2. LOWER_FOO will be resolved by the wev-ask plugin.
You will be prompted to enter a special value, which will be cached for 30 seconds.
Your value will be returned as lower-case.
3. UPPER_FOO will be resolved by the wev-ask plugin.
You will be prompted to enter a special value, which will be cached for 30 seconds.
Your value will be returned as upper-case.
Now let's try it!
For this example, I'll assume you're developing in macOS or Linux and have env installed to print environment variables:
wev env
You'll be prompted three times to enter a value. Enter Foo each time.
Finally, env will output your environment variables, and you should see these three:
DEFAULT_FOO=Foo
LOWER_FOO=foo
UPPER_FOO=FOO
To verify the caching, run wev env again within 30 seconds. This time, you should see env run directly without being prompted for values.
