icornwell / dweeve Goto Github PK

What it is/does:

• d~weeve is a research / learning project
• d~weeve transpiles the Mulesoft Dataweave 2.0 syntax into javascript and executes it
• d~weeve supports nearly all of the Dataweave language sytex / features
• d~weeve accepts json or xml payloads, but currently only emtis json
• d~weeve is for fun and experimentation

What it isn't/doesn't:

• d~weeve is not quite a full implementation of Dataweave 2.0 (but it is getting close for core library functions)
• d~weeve is not for production / real use
• d~weeve doesn't do some Dataweave functions (it as alphabetically all a-p(ish) + some) (but they are easy to add)
• d~weeve doesn't do type coercion (it's javascript so things are a little more flexible, it does support 'is' and 'as' though)
• d~weeve doesn't have any ouput formats other than json, depsite having an xml output declaration

d~weeve uses nearley https://nearley.js.org/ for grammar and parsing

There was a branch 'dweeve4browser' with some hacks and tweaks for running in the browser, killed this as this now has a nicely babel'd lib build.
