Question 1

How to install Gonzales PE with npm?

Accepted Answer

Install via npm using the git dev branch: `npm install --save git://github.com/tonyganch/gonzales-pe.git#dev`. Note that this relies on the development version, which might not be stable for production.

Question 2

Gonzales PE vs PostCSS: which should I use?

Accepted Answer

Gonzales PE is better for deep AST manipulation in SCSS/Sass/LESS due to native syntax support, while PostCSS offers a larger plugin ecosystem for common transformations. Choose based on your need for preprocessor parsing versus plugin convenience.

Question 3

How to traverse and modify the AST with Gonzales PE?

Accepted Answer

Use methods like traverseByType to iterate nodes by type, and insert or removeChild to modify the tree. The README provides examples, such as removing comments with traverseByType('multilineComment', callback).

Question 4

Does Gonzales PE support newer CSS features like grid or custom properties?

Accepted Answer

The README doesn't specify, but as a CSS parser, it likely handles standard CSS; check the node types documentation for specifics, though preprocessor syntax is its primary focus.

Question 5

What are the performance implications of using Gonzales PE?

Accepted Answer

Performance data isn't provided in the README. For large files, AST manipulation can be memory-intensive, so benchmark parsing speed and tree operations in your use case.

Question 6

How to handle parsing errors in Gonzales PE?

Accepted Answer

Error handling isn't detailed in the README; wrap parse calls in try-catch blocks and inspect error objects, as the parser may throw on invalid syntax for the specified preprocessor.
