Use Cases

• Teams migrating from Stylus to LESS for broader tooling support
• Developers switching preprocessors to align with a LESS-based UI framework
• Projects consolidating multiple preprocessor syntaxes into one
• Frontend teams standardizing on LESS for consistency across repos

Tips

• Verify that Stylus variables map to LESS @variable syntax
• Check that Stylus conditionals convert to LESS guard mixins
• Review nested selectors for proper LESS & parent references

Fun Facts

• LESS and Stylus both run on Node.js, making this conversion between two JavaScript-based preprocessors.
• LESS uses @ for variables while Stylus has no required prefix, requiring a syntax transformation during conversion.
• Both LESS and Stylus support lazy evaluation of variables, unlike SCSS which uses imperative variable scoping.

FAQ

Why convert Stylus to LESS?

Usually because you're migrating away from Stylus (it's effectively abandoned) and LESS is already established in your project.

What syntax differences matter?

LESS requires braces and semicolons; Stylus doesn't. Variables use @ in LESS, $ in Stylus. The tool handles both.

Will mixins translate cleanly?

Basic mixins yes. Stylus's transparent mixins (used like functions) need manual review — LESS mixins have slightly different invocation.

Is this lossy?

Mostly lossless. Edge cases: Stylus's @block values and deeply chained arithmetic may need manual cleanup after conversion.
