3 The Syntax Warnings Language
| (require racket/base/warn) | |
| packages: syntax-warn, syntax-warn-lang | |
This library provides a variant of the racket/base language that adds syntax warning wrappers around various forms. For example, the require binding introduced by this language enforces a few "good style" practices around require clauses.
When racket/base/warn is used as a #lang language, everything from racket/base is provided. Various forms are adjusted to attach syntax warnings in certain cases. Warning kinds for these warnings are also exported.
syntax
(require require-spec ...)
Like in racket/base, but warns require:phase-order
when the given require-spec forms are not in
phase order. Phase order is for-syntax
first, for-template second, for-label third,
for-meta fourth, and all other forms fifth.
