Helper scripts to build and test CodeMirror packages.
The exports (build
and watch
) from this package build packages
that conform to the conventions of the various @codemirror
packages.
They do the following:
Mangle the code to convert our
///
doc comments to/** */
comments, so that TypeScript will not strip them.Run the TypeScript compiler, catching the output in memory.
Run rollup and rollup-plugin-dts on the result to emit the CommonJS and ES modules, as well as a bundled
.d.ts
file, todist/
.
There's also a cm-buildhelper
binary which builds the main file
specified as its first argument. This is used by the individual
packages in their prepare
scripts.
NOTE: This tool will add a /*@__PURE__*/
annotation in front of
every top-level function call, to allow tree-shaking of things like
Facet.define(...)
. This is likely to break some styles of code
(which, say, uses a side-effecting helper function to build up some
top-level data structure), but I wasn't able to find another approach
for working with the crude current state of JS dead-code detection
tools.
The cm-runtests
binary helps run tests. Given a list of directories,
it'll run ./test/test-*.js
as plain mocha tests, and
./test/webtest-*.js
using a Selenium headless browser.
You can also pass it a --server
argument to start a test server that
you can interact with in your browser.
