# Approach:
|
||
|
|
# 1. Find variable declaration in the form of "$my-var: anyvalue"
|
||
|
|
# 2. Loop through found variables and find occurrences of each variable in all sass files
|
||
|
|
# 3. Filter out vars that occurred only once
|
||
|
|
#
|
||
|
|
# Run from command line with `build/lint-vars.sh scss`.
