Update transpilation docs (#4700)
2017-09-16 12:32:48 -04:00
### Compatibility
Option to transpile with Babel (#4697) * Upgrade Babeli (now babel-minify) which fixes the bug that was forcing us to run Babel twice for transpilation * Add --transpile option (WIP) * Node API always compiles a string, so it doesn’t need the option to pass a path to an options file, it can always just pass an object to `transpile`; get `transpile` working with `eval` * Not allowing argument to `--transpile` so don’t need to cover so many cases * Don’t need to worry about `sourceMaps` option to pass to Babel, `inputSourceMap` overrides it * Rewrite Webpack test to use Node API * Make the compiler safe again for browsers and Webpack/Browserify * Node version of CoffeeScript.compile passes reference to Babel if transpile is requested * Test Node API for transpile option * Test for merged source maps * Test for Node API error message * Only stop searching for Babel options if a package.json has a truthy "babel" key * Update docs

Regular expressions `s` (dotAll) flag (#4880) * Support ES2018 regex dotall flag * Test in Node 9 * Alphabetize regex flags * Split regex dotall test into its own file, use new feature detection method of loading it * Update docs to explain compatibility for ES2018 and newer Node features * Remove unnecessary paragraph

Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. Here are some notable exceptions:

This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to [node.green](http://node.green/) for full details. You can [run the tests in your browser](test.html) to see what your browser supports. It is your responsibility to ensure that your runtime supports the modern features you use; or that you [transpile](#transpilation) your code. When in doubt, transpile.
