研究方向

使用回報的命令 bunx jco componentize world.js --wit wit -o ts-typescript.wasm -d clocks -d random -d http 重現失敗,並檢查 node_modules/.pnpm/[email protected]/node_modules/change-case/dist/index.js 中的 Unicode 屬性正規表示式。透過 src/componentize.js 第 305 行附近以及回報的 jco 進入點追蹤該失敗。完成的標準是相同的輸入可以在沒有 Wizer 初始化錯誤的情況下被 componentize。

描述

bug good first issue

I am trying to wrap typespec into a component. It pulls in change-case library which uses regular expressions with Unicode. componetize is failing on these regular expressions:

var SPLIT_LOWER_UPPER_RE = /([\p{Ll}\d])(\p{Lu})/gu;
var SPLIT_UPPER_UPPER_RE = /(\p{Lu})([\p{Lu}][\p{Ll}])/gu;
var SPLIT_SEPARATE_NUMBER_RE = /(\d)\p{Ll}|(\p{L})\d/u;
var DEFAULT_STRIP_REGEXP = /[^\p{L}\d]+/giu;

The code is from here:
node_modules/.pnpm/[email protected]/node_modules/change-case/dist/index.js
https://www.npmjs.com/package/change-case
https://github.com/blakeembrey/change-case/blob/main/packages/change-case/src/index.ts

$ bunx jco componentize world.js --wit wit -o ts-typescript.wasm -d clocks -d random -d http

Copilot says:

SpiderMonkey, the JavaScript and WebAssembly engine used in Mozilla Firefox, supports Unicode property escapes as part of the ECMAScript 2018 (ES9) specification. This feature allows you to use Unicode property escapes in regular expressions to match characters based on their Unicode properties.

Enabling Unicode Property Escapes in SpiderMonkey

To ensure that SpiderMonkey is compiled with support for Unicode property escapes, you need to use a version of SpiderMonkey that supports ECMAScript 2018 or later. Most modern versions of SpiderMonkey, including those used in recent versions of Firefox, already include this support.
