为从 Coffeescript 编译的多个连接的 javascript 文件生成源映射 [英] Generating source maps for multiple concatenated javascript files compiled from Coffeescript

问题描述

有人在这方面取得过成功吗?

Has any one had any success with this?

推荐答案

我认为这或多或少是一个未解决的问题:https://github.com/jashkenas/coffee-script/issues/2779 .最后一个有意义的评论来自一个月前的 jwalton.

I think it's more or less an unsolved problem: https://github.com/jashkenas/coffee-script/issues/2779 . Last meanigingful comment was from jwalton, a month ago.

不过，增加对它的支持似乎不是火箭科学，所以它可能很快就会到来.

Still, it doesn't seem rocket science to add support for it, so it will probably come soon.

Michael Ficarra(CoffeeScript Redux 的创建者)建议使用 https://github.com/michaelficarra/commonjs- 无处不在 .

Michael Ficarra (creator of CoffeeScript Redux) suggested using https://github.com/michaelficarra/commonjs-everywhere .

两个警告:

• 它仅适用于捆绑 CommonJS 模块.
• 它使用的是 CoffeeScript Redux，它仍处于测试阶段(尽管看起来工作得很好)，并且与原始 CoffeeScript 编译器不是 100% 兼容.

所以这不适用于您特别要求的连接".

So this does not work for what you ask for specifically, "concatenation".

您可能会很幸运:combine-source-map 和/或generate-sourcemap，均出自同一作者.

You might have luck with these: combine-source-map and/or generate-sourcemap, both by same author.

这看起来很简单:https://npmjs.org/package/mapcat.您只需将咖啡编译器生成的各个源映射文件提供给它.

This looks really simple: https://npmjs.org/package/mapcat . You just have to feed it the individual source map files generated by the coffee compiler.

Mariusz Nowak 刚刚发布 webmake-coffee.与 CommonJS Everywhere 一样，它需要将代码组织为 CommonJS 模块.与其他地方的 CommonJS 不同，它使用常规的 CoffeeScript.

Mariusz Nowak has just released webmake-coffee. Like CommonJS Everywhere, it requires code to be organized as CommonJS modules. Unlike CommonJS everywhere, it uses regular CoffeeScript.

Grunt Coffee-Script 插件 似乎也有源映射支持连接文件很长一段时间(两个月)，有效地证明我原来的答案是不正确的.

It also seems the Grunt Coffee-Script plugin has had source-map support for concatenated files for quite a while (two months), effectively proving my original answer to be incorrect.

即将推出的 Snockets 2.0 版也将支持它.

The upcoming version 2.0 of Snockets will have support for it too.
